The Benefits and Operating Tips of Barefoot Running Technique

There have been great deals of questions over the years as to regardless of whether barefoot running poses а much better benefit or more risk to runners, some runners said that barefoot running technique is very helpful and less traumatic for the runner.

Actually barefoot running technique has been going on for centuries, back in the day shoes were not common. Those that are proponents of barefoot operating claim that the human body has evolved over thousands of years to run with out shoes. Because of this, humans run most efficiently and with the proper technique when barefoot. When operating barefoot, the strike of the foot consistently lands at the forefront and then works its way to the heel while working with muscles to ease the force. Since running is a remarkable sport, then again it requires healthy feet and a healthy musculoskeletal system. When using modern shoes the strike of each step is concentrated onto the heel which puts a lot of stress onto both the muscles and bones, most runners lose their natural foot function and natural operating method. Barefoot running technique does not have those risks given that it does not go against the natural strike of the foot.

A runner who is running barefoot usually has their stride underneath their body. This means the ball of the foot strikes the ground even with or slightly behind the rest of the body. This takes a fantastic deal of pressure off of each strike to the ground and stride looks highly natural and simple. Landing on your heel with a dead straight leg sends an impact weighing twice your body-weight appropriate through your ankle, knee, and hip into your lower back - there is no shock absorber other than the joints it travels by means of. When you land on your mid-foot, your knee is slightly bent to absorb some of the effect into our calves and quads and away from our joints. If you take your shoes off and try a couple of hundred meters barefoot, you will plenty of likely discover that you not surprisingly start to run mid foot.

Barefoot running technique is also being an option to injured runners or runners with chronic injuries as they realize that are able to run again. Most ailments are caused from the shock our feet have to absorb each and every time the heel hits the ground, which lead to injuries and chronic pain. Running barefoot puts the pressure on the ball of the foot where it was meant to be as opposed to the heel exactly where a majority of runners land when wearing shoes. The ball of the foot was meant to be used as natural shock absorber. Run barefoot for a couple of yards and see if you land on your heels. Changes are you won't. In many countries, barefoot running is nevertheless the norm. Studies show that barefoot running is related with decrease cases of ankle sprains and strains, knee injuries and a lower instance of chronic decrease leg injury including shin splints.

If you try to use barefoot running technique, you're going to obviously, nearly automatically, adopt a barefoot running approach to safeguard your heel by landing on the forefoot. As compared to landing on the heel, landing on the front of the foot creates a smoother cycle of effect without having 1st spike of pressure. Runners who use a pattern of forefoot planting - with its moderate effect forces - have a reduced incidence of particular running-related injuries, such as sprained ankles, plantar fasciitis, and shin splints.

Due to this interest in barefoot running technique of shoe producers are today coming out with new shoes that simulate running barefoot. The most popular of which is Vibram Five Fingers. These shoes have thin rubber bottoms to defend your feet from harmful objects for instance sticks, glass, and rocks. They at the same time are including toe socks in that they have a place for each toe. This business enterprise's sole purpose is to offer you shoes that simulate barefoot activity. Some other shoe manufacturers that are making barefoot design shoes are New Balance, Nike, and Saucony. New Balance came out with their Minimus collection which is highly very same to five fingers in that it has highly small cushioning. Saucony's Kinvara line has a dropped sole to try to steer clear of heel striking. Nike's cost-free line has a segment sole which allows the foot to move freely but in spite of this maintains the cushioning, among them Vibram Five Fingers is the closest to operating barefoot running technique, and it readily gives protection with the rubber bottom.

How Often Should I Do Physical Exercise, and When Should I Do Physical Exercise Regularly?

In general, may people did less than one 30-minute session of moderate or vigorous exercise per week in America, actually you may find that it is more convenient and realistic to have a twenty- or thirty-minute workout each day, varying the muscle groups exercised so that all muscles arc addressed on a regular schedule. Or perhaps you would prefer a one-hour full-body routine every third day. You may maintain the status by exercising less frequently; however, exercising on a regular schedule encourages steady gains in muscle tone and strength.

It is imperative that you schedule daily physical exercise sessions to accomplish the toning, aerobic, and stretching exercises that will move you toward your fitness goals. Some physical trainers teach three one-hour muscle-toning classes each week at the parks. In addition, the goal is to perform forty-five to sixty minutes of aerobic exercise four to six days per week. You should establish discipline to accomplish your fitness goals. Schedule your workouts realistically, and then insist that you and other family members honor this time. A disciplined lifestyle recognizes that actions have consequences. Often, it is the difficult choices that propel you toward positive goals.

People are always wonder when the best time to do physical exercise is, and the physical trainers’ answer is always the same: the best time is whenever you have the time. That said, there are some advantages to working out at different times of the day. If you work out in the morning, your metabolism gets a boost that lasts throughout the clay, and you have more control over your time. If you work out in the afternoon or evening, your muscles and joints are warmed up and more flexible, and the exercise may be more relaxing. If not performed too close to your bedtime, it will help you to wind down. Another option is to split your workout into several sessions during the day.

Strategies for Prevention of Travel-associated Deep Venous Thrombosis(DVT)

Spring and summer is travel time in the United States. It is estimated that 60,000 individuals in the United States die each year from pulmonary embolus. Each year, at least 100,000 deaths are attributed to deep venous thrombosis and pulmonary embolisms. How widespread is Deep Venous Thrombosis? Each year, 600,000 patients will encounter some type of venous thromboembolism or Deep Venous Thrombosis. The most Deep Venous Thrombosis is normally in the legs, approximately 70-80% of Deep Venous Thrombosis take place in the thigh region and 20- 30% happen in the calf. However, Deep Venous Thrombosis can simultaneously develop in each leg, causing bilateral swelling. If only one leg is swollen, this is more suspicious for Deep Venous Thrombosis than if both legs are swollen. The symptoms normally related with Deep Venous Thrombosis are discomfort, tenderness, and swelling in the area where the clot takes place, and frequent in ladies as well as men who have experienced leg injuries. It is а clot that forms deep in legs, common among post-surgery patients, frequent to air travelers, hormonal contraception, obesity.

Long duration travel is a weak risk factor for the development of Deep Venous Thrombosis. Deep Venous Thrombosis is a multicausal disorder and the accumulation of risk factors added to an individual’s inherent thrombotic risk determines whether or not thrombosis develops. In clinical practice decisions about thromboprophylaxis are made by considering the patient’s thrombosis risk and the illness or proposed surgical intervention. A similar approach should be taken to travel-related thrombosis where risk is related to pre-existing factors and duration of travel. The data suggest that duration of travel of 3 hours upward is associated with a thrombotic risk. The incidence of symptomatic Deep Venous Thrombosis, most of which are confined to the calf, in low risk travelers after 8 hour flights is around 0.5% and the incidence of early symptomatic pulmonary embolism in all flyers is around 1 in 2 million. To these points the experts proposes as follows recommendations:-

1) Maintaining mobility may prevent Deep Venous Thrombosis and in view of the likely pathogenesis of travel-related Deep Venous Thrombosis maintaining mobility is a reasonable precaution for all travelers on journeys over 3 hours.

2) Travelers at the highest risk of travel-related thrombosis undertaking journeys of greater than 3 hours should wear well fitted below knee compression hosiery. Often, compression stockings are recommended by а doctor to relieve pain, cease swelling, and improve blood circulation. First, before discussing compression therapy, we should distinguish between "Graduated Compression Stockings" and "Anti-Embolism" stockings. Compression stockings could be employed to manage swelling in the legs. Compression stockings, in some circumstances, have been utilized to encourage suitable circulation. If you have to have a greater level of compression, your doctor will know and recommend a level of compression accordingly.

3)      Where pharmacological prophylaxis is considered appropriate, anticoagulants as opposed to anti-platelet drugs are recommended based on the observation that in other clinical scenarios they provide more effective thromboprophylaxis. Usual contraindications to any form of thromboprophylaxis need to be borne in mind.

Prevention of Ligamentous Sports Injuries to the Hand and Some Factors about Postoperative Rehabilitation

Ligamentous sports injuries to the hand have been witnessed for an expanding participation in all types of activities, ranging from leisure sports to competitive athletics, at both the amateur and the professional level. The prevailing enthusiasm for physical exercise and proper body conditioning has unfortunately been accompanied by an increased incidence of sports-related injuries with a variety of disparate clinical manifestations. This has spawned a host of common eponyms associated with particular games and specific injuries, and terms such as baseball finger, tennis elbow, skier's thumb, golfer's injury, boxer's fracture, bowler's neuroma etc., are familiar terminology.

The hands, being the principle tools of implementation of most acts, are constantly being exposed to sudden and often violent physical forces. The compact and intricately structured yet delicate joints of the hand are extremely vulnerable to trauma of varying severity. In the heat of competition, with perhaps the game on the line, scant and often cursory attention is paid to potentially serious injuries. The common refrain, it's only a sprain or jammed finger, only hastens the injured player's return to the playing field, with the possibility of further aggravation and disruption. Not only are elementary principles of diagnosis and primary care often disregarded, but the optimal and definitive management of the injured joint is possibly compromised. The sequelae of chronic pain, swelling and limitation of motion and function are therefore not surprising.

The vast majority of injuries to the small joints of the hand result in partial tears of the ligamentous supporting structures. Even simple dislocations are easily reducible and generally stable. Partial ligament injuries, once accurately diagnosed, respond favorably to a short period of protective immobilisation with consistent recovery of function.

Partial ligament tears and simple dislocations need to be distinguished from more serious injuries that cause significant structural disruption and result in pathological characteristics that either precludes a successful closed reduction or compromise joint stability, the category of serious joint injuries includes:

1.    Complex dislocations.

2.    Unstable fracture-dislocations.

3.    Complete collateral ligament disruptions.

Prevention of an injury is obviously preferable than having to treat it once it has happened. Unfortunately, most sports-related injuries occur in a split second and in the heat of the moment. Attention directed towards prevention must focus on a thorough understanding of the causation and mechanism of athletic injuries in order to identify specific factors whose elimination or modification would help to significantly minimise their occurrence. Supervised training and proper body conditioning are essential requisites for operating safely at peak performance levels. Inadequate training or lack of physical fitness increases susceptibility to injury. Similarly, improper playing techniques or faulty delivery mechanics predispose towards repetitive overuse syndrome. Another frequently overlooked aspect in the prevention of injury is the use of proper equipment and safety gear. These should be designed and manufactured on the basis of a thorough study of the protective needs of individual sports, without being overly cumbersome or restraining. The last, but not the least important preventive measure is the dissemination of appropriate knowledge and information to inculcate increased awareness in the general public, the players and their training and managing personnel. Usually, these people are the first to confront the injury, give advice and render initial treatment, and what they do or may not do will have a major bearing on the appropriateness and quality of primary care.

Postoperative rehabilitation is as critical to overall recovery as the operation itself, and frequently more difficult and demanding. After surgical repairs, the injured joints are preferentially immobilised for a variable length of time depending on specific circumstances. Immobilisation of the injured hand should take cognisance of the 'protective position' whereby the small joints are maintained in a physiologically acceptable posture that prevents contractures of the critical capsular and ligamentous structures. The essential elements of the protective position include extension of the interphalangeal joints, flexion of the joints and wide palmar abduction of the thumb. Custom fabricated splints are available in a variety of shapes, sizes, styles and designs, and serve to function for static or dynamic purposes. They are easily applied, and ensure adequate protection with minimal unnecessary constraints. Protection of an injured joint should be maintained until the 'acute inflammatory reaction' initiated by the injury has completely resolved; this is clinically indicated by the subsidence of pain and swelling with the restoration of functional mobility, also rehabilitation following a serious joint injury is a difficult task that requires cooperation, diligence and perseverance from the patient, and diagnostic acumen and surgical skill on the part of the physician to ensure a mutually satisfactory outcome.

Heat therapy techniques after sports injury

The most useful of heat therapy after sports injury consist of: immersion in hot water, hot packs, paraffin-wax baths and electric pads.  Heat therapy must not be used immediately after an injury, but should be delayed for at least 12 to 24 hours. It causes a dilatation of the capillaries of the part under heat therapy, and if used too soon aggravates the inflammatory reaction and encourages bleeding from the torn blood vessels. The application of heat to an injured part relieves pain and muscle spasm, through its effects on the nerve endings in the skin. This is particularly true of the moist forms of heat, e.g. paraffin-wax and hot packs. Heat also assists in the repair process by increasing the blood supply to the injured area.

Simple heat therapy have a direct heating effect on the skin, heating of the structures which lie immediately beneath the skin, such as ligaments, is possible to a limited degree by conduction, i.e. the temperature of the skin is raised and the adjacent tissues absorb some of the heat. Short-wave diathermy and ultrasonic therapy are capable of heating the deeper structures after sports injury.

Immersion in hot water

The heat penetrates the skin to a small degree only, and the heating effect on the deeper tissues is negligible. Generally the treatment Is used only when other forms of heat therapy are not available. Immersion time: 20 to 30 minutes. 

Hot packs

The heating effect after sports injury is again superficial. Hot packs are widely used, however, because they form a very simple and practical method of applying moist heat in the relief of pain. The toweling pack has now been largely superseded by the steam pad. This pack is inexpensive, and can be easily used at home by the player. It consists of a thick linen pad, 12x10 in., which contains special filler which absorbs up to three times its own volume of water. It is stitched into several sections, so that it is flexible and can be molded to any part of the body.

The pad is placed in a saucepan of hot water, and boiled for about 30 minutes. It is next lifted out of the water by the loops which are attached to each corner, and wrapped in four or five thicknesses of Turkish toweling. The pad is then placed on the injured part, and covered with two or more layers of toweling to conserve heat. The top towel is usually wound round the area being treated, to hold the pack firmly in place. The pack is left in position for about 20 to 30 minutes.

Sheets of foam rubber, 1/2 in. thick, may be used to replace the towels after sports injury, this heat treatment simplifies application. After being boiled, the pad is laid on a piece of foam rubber, which is folded over it. A towel is placed over the injured part, and covered by another piece of foam rubber. The pack is placed on top of the rubber square, and held in place by a towel. The foam rubber can be used a great many times before it needs to be replaced. 

Paraffin-wax baths

When a wax bath is used the heating effect is slightly greater than that produced by the two previous treatments after sports injury. If the wax is applied as a pack the heating effect is not so pronounced.  Wax baths are only suitable for injuries of the hands, wrists, elbows, feet and ankles.

The wax is usually heated to a temperature of between 110°F. and 120°F, and it is best to use a wax with a low melting point (110°K).  A wax pack is made by using a 2 in. paintbrush, and applying six to eight coats of hot wax to the affected area; the wax may also be applied with a soup ladle. The part is then covered with grease-proof paper, well wrapped in a large piece of old blanket, and left for about 20 to 30 minutes.

Electric pads

Superficial heating only, as with the hot pack after sports injury, the dry form of heat produced by an electric pad is not so effective in relieving pain as moist heat.

Cold treatment is used immediately after injuries

Cold applications and treatment:

The simplest and most effective method of applying cold treatment consists of immersing the injured part in ice-cold water. Other methods include ice-packs and compresses. Cold applications must be applied immediately, or as soon as possible, after the injury has taken place. It should be noted, however, that cold can be used to relieve pain and associated muscle spasm in the later phases of recovery.  Indeed, in recent years many therapists have advocated cold applications and treatment for this purpose instead of traditional forms of heat. 

Effects of cold applications and treatment

The application and treatment of cold to an injured part relieves the pain, through its effect on the nerve endings in the skin: in some cases the relief seems to last for a longer time than when heat is used as a palliative agent. Physiologists investigating the effects of local cooling on the body tissues have not only found that cold reduces the conductivity of nerves, but that the susceptibility of nerves to cooling varies with the type and size of the fibers. Experiments have shown that some smaller diameter fibers are more readily influenced than large diameter fibers. If the intention is to use cold to reduce muscle spasm and initiate active movement a temperature of between 12°C. and 15°C. (53’6° F. and 59°F.) is best.

Limiting swelling

It is possible that cold applications and treatment also help to restrict the traumatic effusion or swelling which accompanies a local inflammation, by causing a constriction of the dilated capillaries of the superficial structures. The practical difficulty associated with this form of treatment is that the initial vasoconstriction is followed later by a marked vasodilatation.

Effect on deeper structures

Cold applications and treatment have little effect on the capillaries of the deeper structures. This is because the network of blood vessels in the skin acts as an insulator; in other words, the blood flowing through the skin vessels absorbs the cold before it can penetrate to the deeper structures. Because of this, the immediate treatment of soft-tissue injuries should consist of pressure bandaging combined with a cold application and treatment.

Cold Treatment techniques:

Immersing in ice-cold water

This cold treatment is suitable only for injuries of the wrist, hand, foot and ankle. It consists of immersing the injured part for about 10 to 20 minutes in a pail or deep bowl of cold water to which ice cubes or crushed ice have been added. It is advisable to check the temperature of the water with a bath thermometer. After cold treatment the wet pressure bandage is removed and a new bandage applied. If immersion is not practicable the pressure bandage may be soaked thoroughly, the water being applied with a sponge

Wet towels

Several pieces of terry toweling, about 30 x 24 in. are soaked in a bucket containing a mixture of cold water and crushed or flaked ice. The towels are wrung out to get rid of excess moisture, and then applied this cold treatment to the injured area. They are changed every minute, and the whole sequence of cooling should last for about 10 to 20 minutes. From a practical point of view half the number of towels required (having been folded lengthwise) should be left soaking in the bucket while the others are used.

Cold packs

Damp terry toweling bags of a suitable size are filled with flaked-or crushed ice. The injured part is wiped with oil to prevent the possibility of an ice burn, and covered with a paper tissue to prevent soiling of the bag. The ice pack is then molded round the part. If the trunk is being treated it is helpful to hold the pack in place by a broad canvas strap passed round the body.  As an alternative to toweling plastic or rubber bags may be used. 

Ice massage

A paper tissue is wrapped round one end of an ice cube. The cube is then massaged slowly over the painful area for about 5 minutes. This is a useful form of cold treatment for relieving pain over a small area (ligaments, for example); it is possible that ice massage acts as a counter-irritant and helps to reduce the conductivity of the pain fibers in the nerves involved.

Cold compresses

A piece of white lint, cut and folded to the required size (to make a double thickness), is soaked in ice-cold water.  The lint is squeezed out gently, so that it is not made too dry, and applied to the affected part. It is then covered with a piece of jaconet or oiled silk, and bandaged lightly in position with a few turns of cotton bandage. The compress of cold treatment must be changed frequently, and used for about 20 minutes. A pressure bandage is then applied. In general, cold compresses have a very limited effect.

The tips for Sports Injury Treatment when the injured body parts can be used almost normally

(1) To accustom the injured tissues to being without support. This is achieved by using an elastoplast or crepe bandage support. Both types of support allow considerable freedom of movement, but provide the injured structures with a certain degree of stability. It is never advisable to take away all support from the injured tissues before they have recovered completely. If this is done the injured part tends to swell when used, owing to a leakage of the blood

fluid from the capillaries into the tissue spaces. The swelling gives rise to considerable pain and stiffness. The leakage of the blood fluid is due to a loss of tone of the capillary walls, which have become accustomed to the firm support of the original strapping.

(2) To disperse any residual effusion or thickenings. This is accomplished by the auto-massage pressure of the strapping or crepe bandage. When strapping is used the massage can be localized most effectively by strapping over a pad of adhesive felt. Heat treatments, remedial exercises and deep massage are also of great value.

(3) To strengthen the muscles of the injured part, and to restore full joint movement. The player practices all types of strengthening and mobilizing exercises, including weight-resisted exercises. Usually the supporting bandage or strapping is removed for the treatment session; it may be retained for the stronger exercises.

(4) When Sports training is started, please pay attentions to prepare the injured part for the normal stresses and strains of the game or event. This is done by the player resuming training and carrying out all the normal movements which are expected of him. The Injured part should be supported by a firm strapping, to prevent a recurrence of the injury.

For two to three months after the injury has recovered fully the player should have the injured part strapped firmly each time he takes part in a game or event. The time factor, of course, will depend on the severity of the original injury.

The treatment for 24 to 36 hours after sports injury, until injured body parts can be used almost normally

(1) To disperse the traumatic effusion, i.e. (a) to spread the free blood fluid into the surrounding tissues, so that it mil be drained away by the uninjured lymphatic vessels and veins, and (b) to assist the drainage of any excess amount of synovial fluid . This aim is accomplished by the use of strapping and various forms of physiotherapy.

Strapping. The injured part is strapped firmly and the player encouraged using it as normally as possible; in injuries of the lower limb this usually includes walking. The pressure of the strapping on the moving muscles and joints acts as a most efficient form of auto-massage, which improves the circulation and the lymphatic drainage of the part.

To increase the effect of the massage the strapping may be applied over a pad of adhesive felt, which is positioned over the injured tissues.

Two types of strapping may be used: (a) Zinc oxide adhesive plaster, and (b) Elastoplasts combined with supporting strips of zinc oxide plaster. Support is necessary until the traumatic effusion has been completely dispersed; this may take anything from two or three days to two weeks or more, depending on the severity of the original injury.

Protecting the skin. The skin is often sensitive to the adhesive spread, or may be irritated by the strapping being changed frequently, as when daily massage is given. To protect the skin the strapping may be applied after the injured part has been covered by a few turns of ordinary cotton bandage, which has been previously soaked in cold water. The strapping must overlap the bottom and top edges of the cotton bandage by about i to I in., so that it is securely fastened to the skin.

When using elastoplasts another method of protecting the skin may be tried. The non-adhesive side of the strapping is applied to the skin; the reinforcing strips of zinc oxide plaster are then arranged over the adhesive surface. Any areas which are left uncovered are powdered with talcum powder to make them less sticky.

Joint injuries. In dealing with a joint injury which is associated with a large synovial effusion strapping is not used. A pressure bandage is applied to the joint, the injured limb is rested, and the controlling muscles exercised by static contractions and other non-weight-bearing exercises which do not cause movement of the affected joint.

Physiotherapy. Massage, exercises, contrast baths, faradic stimulation and anodal galvanism may be used to disperse the traumatic effusion. Two or more of the treatments are generally used in combination, and the choice depends on individual preference and the stage of recovery. In the early stage, for example, anodal galvanism, faradism and contrast baths may be employed; later, massage and exercises.

(2) To prevent movements which might stretch the damaged structures and break down the delicate repair tissue which joins the ends of the torn fibers. This aim is achieved, as far as possible, by arranging the strapping so that it holds the injured tissues in a relaxed position. With many muscle injuries this is not practicable, and the therapist has to support the affected muscles in a circular manner, and instruct the player not to put them on the stretch.

(3) To assist repair. The aim is accomplished by the measures which have been previously outlined for improving the circulation and preventing the damaged structures from being stretched. Some form of heat therapy may also be used to improve the blood supply of the injured part-short-wave diathermy, infra-red radiation, radiant heat or hot packs.

(4) To strengthen the muscles of the affected part, especially those which may have been injured. The player practices some simple remedial exercises which do not stretch the damaged structures or require too much muscular effort; in practice this means exercising within the limit of pain.

(5) To maintain the normal range of movement of the joint or joints of the injured part. This is done by using exercises of the type suggested above. Unless the joints are exercised their movements may be seriously limited by the formation of thickenings and adhesions.

Immediately treatment after the sport injuries for about 24 to 36 hours

(1) To limit the traumatic effusion (swelling), and so restrict the amount of “Sticky” blood fluid in the tissue spaces. This is achieved by applying a pressure bandage to the injured part. A calico or crepe bandage is used over several layers of cotton wool, each layer being compressed by turns of bandage; it is essential that the turns cover the injured part adequately, and extend well above and below it. In general calico bandages are used when treating joints and crepe bandages when dealing with muscle injuries.

Strapping should not be used to limit traumatic effusion in the early stage of injury; it may produce an uneven, cordlike compression, which may increase the effusion. It should be noted, however, that when an injury does not appear to be of a severe nature, and it is considered essential for the individual to continue to use the injured part, an elastoplasts strapping is used instead of a pressure bandage. The principle of allowing an injured player or athlete to resume activity immediately after an injury is basically unsound, and should not be accepted by the trainer or therapist unless he is acting on medical advice.

Ice-Cold Water. When pressure has been applied the injured part may be immersed in ice-cold water for about 10 to 20 minutes; if immersion is not practicable the bandage may be soaked, the water being applied with a sponge for the same length of time. The wet bandage is then removed, and a new pressure bandage applied. The cold water relieves pain, and may help to check effusion by causing a local constriction of the capillaries.

Local Injections of Hyaluronidase. In recent years many doctors have used local injections of hyaluronidase to accelerate the dispersal of traumatic effusion. The injections are used in conjunction with the other forms of physical treatment mentioned in this section.

(2) To prevent movements which might stretch or strain the injured structures and so (a) cause a recurrence of the bleeding, or (b) pull the ends of the torn fibers apart and so hinder repair. This aim is accomplished by supporting the damaged structures with the pressure bandage in such a way that they are completely relaxed, and then to resting the injured part. The type of rest required will depend on the severity of the injury; in injuries of the lower limb it may vary from complete rest in bed with the limb raised on pillows (to assist circulation and aid drainage of inflammatory exudates) to semi-rest, e.g. walking with crutches without taking weight on the injured limb. la injuries of the upper limb a triangular sling may be used to provide rest.

(3) To relieve pain. To a certain extent this aim is achieved by the measures which are taken to fulfill the previous aims pressure, support, cold applications and rest. In addition some type of pain-relieving drug (e.g. aspirin) may be prescribed by the doctor. It should be noted that when rest in bed is required for an injury of the lower limb a considerable amount of discomfort and pain is often experienced if the bedclothes are allowed to rest on the limb. A bedclothes support should be improvised by putting a large cardboard box or a pile of books on the mattress at the foot of the bed.

Minor Sports Injuries and More Serious Sports Injuries

It is convenient to consider sports injuries in two main groups:

(1) Minor injuries, in which there is no real damage to the tissues, such as strains of muscles and tendons; The reactions of the tissues to trivial injuries are often obscure and difficult to assess; in general they are those of a mild, localized inflammation, and pain and stiffness are the main symptoms. Many of the injuries are caused by over-use of the affected part, and clear up with rest; some require support by strapping or bandaging, especially when training is resumed. If more specific treatment is necessary it follows the lines suggested for the more serious injuries.

(2) More serious injuries, in which there is actual destruction of some of the tissues, such as muscle tears and sprains of ligaments. Three main changes occur in the tissues when they are more seriously injured: loss of substance or continuity, rupturing of some of the small blood vessels and localized inflammation.

When some part of a structure is torn or crushed (as by a blow), the small blood vessels of the injured area are ruptured, and bleed into the tissues. The blood seeps between the various tissue layers; its spread is aided by the action of the muscles, the effect of gravity, and the pressure of the membranous coverings. This is the reason why braising often appears in areas which are some distance from the injured part. Soon after the injury the capillaries constrict and the blood clots. The blood then consists of a jelly-like substance and a fluid part (the plasma, which has lost certain elements concerned in the clotting process). The clot seals off the ends of the ruptured vessels, and links the torn tissue fibers together. Special connective tissue cells, known as fibroblasts, grow into the links and eventually repair the damage. The fluid part of the escaped blood is drained away by the lymphatics, and eventually returns to the general circulation.

At the same time as these changes occur the undamaged capillaries in the neighborhood of the injury dilate, so that they hold more blood than usual. Their walls become more porous, and a considerable amount of sticky blood fluid (plasma) and a large number of white corpuscles pass through them into the tissues to mingle with the blood from the damaged vessels. The free blood fluid is known as inflammatory exudates.

These changes are concerned with repair and healing. The inflammatory exudates stimulate the formation and growth of the fibroblast repair cells. The white corpuscles act as scavengers and remove the tissue cells which have been destroyed; they also deal with the blood clot in the same way. The signs of these changes are local heat, redness, swelling and pain. The heat and redness are caused by the extra amount of blood in the arterioles and capillaries of the injured area. The swelling is due partly to the dilation of the capillaries and partly to the accumulation of fluid in the tissues. The pain is either the result of some of the nerves being involved in the injury or of their being compressed by the distended tissues.

Prevention of Chronic Back Strain of Spine Issues

Any work that requires sitting or standing partly bent over for long periods of time can cause extra stress on muscles which can become painful. A vicious circle may develop if chronic strain continues with the muscles becoming less able to withstand strenuous activities and becoming more prone to further injury. Working too long, too hard or holding the back in a fixed position can cause tension, tired muscles, weakness, less control of movement and proneness to back injury and spine issues.

Seating and other work positions should be so designed that the back is not bent for long periods. The best sitting position is with knees higher than hip and lower back flat against a firm back rest for spine health care.

The following simple procedures can also help for prevention of chronic back strain of spine issues:-

(1) Change body position frequently;

(2) Stretch—by clasping hands behind head, bends forward until back is horizontal;

(3) Adjust working height to prevent slumping or excess reaching;

(4) Relax—let shoulders and neck muscles go limp, swivel head and let it droop all the way forward;

(5) Muscles are most rested during sleep by using a firm mattress (or hardwood between springs and mattress) and lying on one side with hip and knees bent.

Prevention of Back Injury and Spine Issues

The use of mechanical aids for load lifting and handling, whenever practicable, is the most effective method of preventing back injury. When manual handling of loads is unavoidable, the worker should be instructed in and apply the principles of safe lifting and handling. These guides are aimed at describing the common stresses imposed on the back by work activity and advising on the prevention of back injury and spine issues as below:-

Principles of safe lifting and handling for spine health care and back pain prevention

The safest methods of manual handling and lifting for prevention of back injury and spine issue are based on the following six principles:-

(1) Correct Grip

The sense of touch and the ability of the hands to carry out both hard and sensitive work is, next to sight probably the most valuable of the senses. The ability of the fingers to maintain pressure is limited, however, and they soon become tired, especially when the hands are being held out in front of the body to hold an object or when they are trying to grip a shiny surface. Gripping with the fingertips will therefore strain the fingers and also the muscles in the forearm. The correct grip uses the palm of the hand and the roots of the fingers and thumb so that prolonged strain on the fingers is avoided. Where boxes or small bins are used regularly to carry materials or objects from one position to another, they should never be fitted with finger holds or narrow handles which encourage the worker to use his fingers.

(2) Straight Back

If the back is bent as a worker reaches down to pick up an object he is off balance, strain is immediately imposed on the muscles controlling the spine by giving them more work to do and the discs between the vertebrae are compressed. When the object is lifted, this weight is added to the already considerable weight of the head, shoulders and arms. All too frequently, therefore, the worker suffers strain in the back muscles, or possibly a slipped disc. In lifting, therefore, the back should be kept straight and the body lowered to reach the load by flexing hips, knees and ankles. The lift is then carried out by using the powerful muscles of the legs rather than the back, which is kept straight, though not necessarily vertical, throughout the movement.

(3) Chin Position

To help maintain a straight back, the chin should be tucked in before the lift is begun. This pushes the top of the head upwards and keeps the top of the spine straight.

(4) Position of Feet

If the feet are close together, the weight of the body and of the load being lifted is balanced on a small floor area. This means that the worker can easily lose balance on his own or from someone bumping into him. The feet should therefore be the width of the hips apart with one foot in front of the other. The leading foot should point in the direction in which the worker will be moving. This balances the load far more securely and means that the worker can more easily ride any bumps he receives while he is lifting and is less likely to lose control of the load.

(5) Position of Arms

Lifting, pushing or carrying with the arms held away from the sides of the body imposes unnecessary strain on the chest upper back and shoulder muscles. The arms should therefore be kept as close in to the body as possible.

(6) Use of Body Weight

If used properly, the weight of the body can help in moving a load by acting as a counterbalance, so reducing the amount of muscular effort needed. It is wrong for the worker to feel comfortable at the beginning of a lifting movement because it means that he is positioned for remaining still. If the body-weight is to be used correctly, the starting position will usually be uncomfortable if he holds the position for more than a few seconds without moving. The action of moving the body from the uncomfortable starting position into a more comfortable one means that the weight of the body is being used as a source of power to overcome the weight and the resistance of the load, without excessive muscular effort. Such a movement must be a smooth one, however, and not a jerk or "snatch".

These six principles can be applied to all manual handling and lifting operations. The essence of them is the controlled use of the body, especially body-weight, and they require thought and practice. However, once they become as automatic as his second nature, the worker can lift and handle loads in much greater safety to himself and other workers than by using the "natural" methods.

Where two or more workers are carrying out lifting or handling operations it is essential that they should work together as a team, one worker, preferably the lightest, giving all necessary orders. Every workplace has its own difficult handling problems, either through environment or, more usually, special processes. Under these circumstances and as a result of long practice, the workers often develop their own skills and knacks in carrying out the work. Provided these skills are acceptable, they should be retained and the worker encouraged adopting correct body movements along with them.

Rules for safe lifting for spine health care and back pain prevention

The basic lifting rule is "use your head" to think things through before starting. Essential Steps are:-

(1) Examine object for size, shape and weight. Decide where and how to hold it. Check for grease, oil, sharp edges. Be extra careful of awkward shapes in difficult situation;

(2) Clear path of obstructions and tripping hazards;

(3) Know where and how the object will be let down; and

(4) Get help if there is any doubt

General rules for all situations are:

(1) Start close to the object. Have a firm footing with feet spread on either side of the load;

(2) Keep back straight—bend knees;Squat down—straddle the load somewhat;

(3) Grasp object firmly. Be sure grip will not slip;

(4) Breath-in—inflated lungs help to support the spine;

(5) Lift with legs—slowly straighten the legs. After legs are straight bring back to vertical position;

(6) Hold object firmly close to body;

(7) Always lift smoothly. Avoid jerky motions. Turn with feet instead of twisting the back.

Activities Predisposing to Back Injury and Spine Health Issues

Work activities predisposing to back injury and spine health issues are:-

(1)Lifting or setting down loads;

(2)Carrying,stacking,pushing,pulling,rolling,sliding and wheeling of loads;

(3)Operation of levers and other mechanical devices;

(4)Maintenance of unbalanced postures while performing these tasks;

(5)Normal movements of the spine aggravating existing damage to intervertebral discs.

Aggravating factors for back injury and spine health issues are:-

(1)Gross overloading of the spine;

(2)Lifting with a bent back or with the object held well out from the body or to one side;

(3)Loss of balance while lifting;

(4)Using a jerking or twisting lifting motion;

(5)Unexpected weight bearing;

(6)Restricted room to maneuver;

(7)Inadequate grip on heavy, awkward, hot corrosive, sharp or slippery objects;

(8)Unstable footwear;

(9)Slippery, uneven or littered floor surfaces;

(10)Uncoordinated team lifting; and

(11)Unfitness to lift

Many jobs require performance of tasks in the seated position. Constant sitting in unergonomically designed chairs in stressful postures dictated by visual or manipulative tasks is a common source of recurrent or persistent back pain. Appropriate workplace and chair design promote maintenance of correct posture and the prevention of postural strain and spine health issues.

Back Strain and Spine Health Issues

Back pain and spine health issues affect many people during their working and exercising life. It is a very common cause of disability and sickness absence with serious consequences for the individual and industry. While a severe accident such as falling or crushing may result in gross back injury the onset of pain is more often associated with repetitive and cumulative accidental and postural stresses, and then lead to serious spine health issues.

The back is a complex system which includes the spine, spinal cord, nerves and muscles according to spine anatomy. The spine supports the weight of the head, most of the trunk and upper limbs. It is composed of 33 bone segments (vertebrae) of which those in the pelvis and coccyx are fused together. Those in the neck, chest and lumbar region possess a limited degree of mobility with respect to one another. Each vertebra consists of a body in front and an arch behind, bearing various bony projections (processes), to which are attached powerful muscles and strong ligaments. The space enclosed by the vertebral body and arch is known as the spinal canal. Between the vertebral bodies are discs (intervertebral discs) composed of a tough outer ligamentous covering and a central core of plastic, viscous tissue (nucleus). The disc is weight bearing, but is sufficiently compressible and flexible to absorb shock and to permit a limited degree of bending and twisting of the spine.

The spinal cord is a cable of nerves running from the brain down through the spinal canal and controlling all activities below neck level. Nerves branching out from the spinal cord send information to the brain and orders to the muscles. There are about 800 muscles producing motions in all directions and they are attached to the bone by over 4 000 tendons.

Repeated spinal stress may cause disruption and degeneration of the intervertebral discs in the lower back (lumbar region) with rupture of the covering of the intervertebral disc and projection of part of the nucleus into the spinal canal where it may compress nerve roots and cause pain in the thigh, calf and foot (sciatica). Most cases of persistent or recurrent low back pain of spine health issues are caused by intervertebral disc degeneration disease.

Don't Let the Sports Injure Children

Some parents premature to let the children in some physical activities, actually some physical activities, not benefit the children’s health status, but easy to cause harm.

The health experts say children are in the growth and development of the period, the body organs and tissues have not yet matured; there are many different from adults of the physiology characteristic, so sports games for kids are unsuitable for children in early.

The children should not attend tug-of-war. According to the physiological theory, the child's heart is in the development stage, when the body load increases, mainly rely on the heart rate increase to gain the supply of blood, therefore, heart is easy to fatigue, and children can't afford such big powers to fight. Medical experts used to test 250 five to six years-old children after the tug-of-war competition, found their heart rate are too high, 30% of children fail to restore normal heart rate after one hour. In addition, the tug-of-war is a very tough against movement, because the pull time last too long and strong external force easy to cause dislocated and soft-tissue hurt.

Children can’t train the muscle too early. In the growth process, height is growing faster than the weight, and their muscle contains more moisture, less protein and inorganic salt, and easy to fatigue. Therefore, in childhood, don't do muscle weight exercise too early.

The children should not stand on his head. If often stand on their head, or every time handstand time is too long, can damage the eyes function in the adjustment of the intraocular pressure.

Children under the age of 10 could not play bumper car. Children's muscles, ligaments, bones and connective tissue and not mature and very fragile, when meet strong collision will cause the sprain and collision hurt.

Scooter games are unsuitable for children under the age of 8. When the children play scooter, the waist, knee and ankle position is easy on injury, so be sure to prepare well the protection, better with parents accompanying then play in a flat and spacious area.

According to children's body growth characteristics, parents could let children skip rope, bounce, playing kids soccer, and basketball games for kids, swimming; these sports games for kids help to increase the height of children, and would not damage their body.
