Marathon running cannot ensure protection from coronary atherosclerosis or fatal coronary artery disease. Writing in the New England Journal of Medicine (Vol. 301: 2, 86-89, 1979), Dr Tim Noakes et al report on their autopsy findings in five marathon runners. Included in their study were the coronary conditions of three runners killed in an automobile accident during a routine training run.

There is still no definitely known reason for the physiological phenomenon of sleep. However one theory is that sleep forms some form of ï¿½restorative processï¿½. With this in mind I have investigated the effect of exercise on sleep as one would expect an increase in the requirement for this ï¿½restorative processï¿½ after exercise.

Objective. The purpose of this study was to determine whether cycling performance improved during a 14-day taper, the time course of any improvement, and the possible physiological reasons for any change in performance. Design. Twenty trained male cyclists (> 250 km/wk) were randomly assigned either to a control group that continued training as usual, or to a reduced-training (tapering) group.

The injuries incurred by 16 international cricketers while on a 5 week tour have been recorded. The physiotherapy treatment for these injuries has also been briefly noted. The purpose of this article is to make the medical team managing a cricket team (or any touring sports team) more aware of the type and extent of common injuries to be expected on a tour. It was concluded that it is important to thoroughly screen each player before undertaking any tours of this nature to identify either present or past injuries. Therefore, a treatment / training programme for the players, with the aim of minimising the possibility of re-injury while on tour, can be advised.

Objective. To determine whether fatigue, measured as a percentage of maximum heart rate (% HRmax), occurred during a six-over bowling spell in fast bowlers. Design. Twenty-one young elite or potentially elite fast bowlers (junior group N = 11; senior group N = 10) were recruited for the study. The bowlerï¿½s heart rate was recorded during a six-over bowling spell in a turf cricket net. The accuracy of each delivery was recorded, and various anthropometric and flexibility data relevant to the physical demands of bowling were also collected.

Every truth has two sides; it is well to look at both before we commit ourselves to either."" Aesop. Like most runners who have contact with doctors, I have experienced Aesopï¿½s truth. Have learned that, as regards this running experience, we runners have one set of truths. The doctors another.

The high incidence of exercise-related injuries, primarily in the form of overuse syndromes to the lower extremities, is a universal problem among recruits being subjected to an intensive physical conditioning programme (basic training) on entering the military service.

The female athlete triad is a triad of disorders observed in adolescent and adult female athletes and includes disordered eating, amenorrhoea and osteoporosis, the severity of which is determined primarily by prior menstrual history. It is not restricted to elite athletes but includes also physically active girls and women participating in a wide variety of sports.

In general, fats may be defined as a group of organic substances which are greasy to touch, insoluble in water and are soluble in alcohol or ether. Chemically speaking fats are organic compounds of carbon, hydrogen and oxygen. The fats in food are called triglycerides (neutral fats). Triglycerides are esters of glycerol (the water soluble component) and fatty acids which are the basic components of triglycerides.

Diabetes mellitus is a common metabolic disease characterized by insulin insufficiency resulting in impaired ability to transport glucose across the cell membrane for its subsequent oxidation. Also, muscle and liver glycogen re synthesis, triglyceride synthesis in adipose cells, inhibition of their breakdown (antilipolytic effect), as well as protein synthesis and storage (anabolic effects) are being impaired. Insulin insufficiency thus leads to metabolic disturbances leading to such common symptoms as fatigue, weakness, weight loss, hunger, overeating, polyuria, and signs of glycosuria, and ketosis.
