The meaning of the symbols of sport seen in a dream.

The ?eld of medicine concerned with physical ?tness and the diagnosis and treatment of both acute and chronic sports injuries sustained during training and competition. Acute injuries are extremely common in contact sports, and their initial treatment is similar to that of those sustained in other ways, such as falls and road traf?c incidents. Tears of the muscles (see MUSCLES, DISORDERS OF), CONNECTIVE TISSUE and LIGAMENTS which are partial (sprains) are initially treated with rest, ice, compression, and elevation (RICE) of the affected part. Complete tears (rupture) of ligaments (see diagrams) or muscles, or fractures (see BONE, DISORDERS OF – Bone fractures) require more prolonged immobilisation, often in plaster, or surgical intervention may be considered. The rehabilitation of injured athletes requires special expertise

– an early graded return to activity gives the best long-term results, but doing too much too soon runs the risk of exacerbating the original injury.

Chronic (overuse) injuries affecting the bones (see BONE), tendons (see TENDON) or BURSAE of the JOINTS are common in many sports. Examples include chronic INFLAMMATION of the common extensor tendon where it

attaches to the later EPICONDYLE of the humerus – common in throwers and racquet sportspeople – and stress fractures of the TIBIA or METATARSAL BONES of the foot in runners. After an initial period of rest, management often involves coaching that enables the athlete to perform the repetitive movement in a less injury-susceptible manner.

Exercise physiology is the science of measuring athletic performance and physical ?tness for exercise. This knowledge is applied to devising and supervising training regimens based on scienti?c principles. Physical ?tness depends upon the rate at which the body can deliver oxygen to the muscles, known as the VO2max, which is technically di?cult to measure. The PULSE rate during and after a bout of exercise serves as a good proxy of this measurement.

Regulation of sport Sports medicine’s role is to minimise hazards for participants by, for example, framing rule-changes which forbid collapsing the scrum, which has reduced the risk of neck injury in rugby; and in the detection of the use of drugs taken to enhance athletic performance. Such attempts to gain an edge in competition undermine the sporting ideal and are banned by leading sports regulatory bodies. The Olympic Movement Anti-Doping Code lists prohibited substances and methods that could be used to enhance performance. These include some prohibited in certain circumstances as well as those completely banned. The latter include:

stimulants such as AMPHETAMINES, bromantan, ca?eine, carphedon, COCAINE, EPHEDRINE and certain beta-2 agonists.

NARCOTICS such as DIAMORPHINE (heroin), MORPHINE, METHADONE HYDROCHLORIDE and PETHIDINE HYDROCHLORIDE.

ANABOLIC STEROIDS such as methandione, NANDROLONE, stanazol, TESTOSTERONE, clenbuterol, androstenedone and certain beta-2 agonists.

peptide HORMONES, mimetics and analogues such as GROWTH HORMONE, CORTICOTROPHIN, CHORIONIC GONADOTROPHIC HORMONE, pituitary and synthetic GONADOTROPHINS, ERYTHROPOIETIN and INSULIN. (The list produced above is not comprehen

sive: full details are available from the governing bodies of relevant sports.) Among banned methods are blood doping (pre-competition administration of an athlete’s own previously provided and stored blood), administration of arti?cial oxygen carriers or plasma expanders. Also forbidden is any pharmacological, chemical or physical manipulation to affect the results of authorised testing.

Drug use can be detected by analysis of the URINE, but testing only at the time of competition is unlikely to detect drug use designed to enhance early-season training; hence random testing of competitive athletes is also used.

The increasing professionalism and competitiveness (among amateurs and juveniles as well as professionals) in sports sometimes results in pressures on participants to get ?t quickly after injury or illness. This can lead to

players returning to their activity before they are properly ?t – sometimes by using physical or pharmaceutical aids. This practice can adversely affect their long-term physical capabilities and perhaps their general health.... sports medicine

Four main types of drug are abused by athletes to enhance physical or mental condition.

Stimulants such as amfetamines can prevent fatigue and increase confidence.

Three types of hormone drugs may be abused: anabolic steroids (see steroids, anabolic) to speed muscle recovery after exercise; erythropoietin to boost the haemoglobin content of the blood, which may increase stamina; and growth hormone to stimulate muscle growth.

Analgesic drugs may be used to mask the pain of an injury.

Betablockers are taken to reduce tremor in sports that require a steady hand.

Aside from the health risks associated with abuse of these drugs, their use is prohibited in many competitive sports.... sport, drugs and
