Lifestyle factors

Doping

Doping increases the risk of injuries and endangers health. It is also illegal, and cheating. Regulations have been developed by the International Olympic Committee and others, and must be followed.

Alcohol

Consumption of alcohol impairs performance and causes a marked increase in the risk of injury. The breakdown of alcohol in the body occurs at a constant speed and is not influenced by such measures as physical exercise or sauna baths. Sport and alcohol do not mix.

Overweight and obesity

The overweight are usually less physically active than their lighter fellows and hence tend to have a less robust musculoskeletal system. This, combined with the greater load they have to support, increases the risk of injury and can accelerate joint degeneration.Obesity is a significant, though probably comparatively minor, risk factor for the development of cardiovascular disease. Its main cause is a surplus of unused food energy; an underlying physical disorder is the exception rather than the rule. The energy surplus is converted into fatty tissue.

A man who has a sedentary job and does no physical exercise in his spare time requires 8000–10 000 kJ (2000–2500 kcal) every 24 hours. Most people’s diets, however, are not ideal, so that in order to ensure a sufficient intake of important nutrients, they have to consume the equivalent of 10 000–12 000 kJ (2500–3000 kcal) daily, which for many people is far more than they need. The problem can be solved by:

– eating smaller quantities of food, but making sure that the diet is well-balanced;
– increasing the rate of metabolism by exercise or other physical activity.

A combination of these two methods is more likely to be successful than one used in isolation.
