Sports without harm to health

There are two sides to sports - benefits and harms. In order for sports to become a harmless activity, it is necessary to take into account the specific effects of sports loads on the body, regardless of the type of sport chosen.

Sports activities always involve burning calories, i.e. energy expenditure. But human energy is not unlimited and in special cases energy expenditure is at odds with improving health. This applies to periods of time when a person is on the threshold of illness, falls ill and recovers from illness. In all these cases, spending energy on sports is excessive and harmful to health. For example, with sports activities, even minimal ones, the heartbeat increases, blood begins to circulate faster through the vascular system, and this can worsen the disease several times. It is for this reason that when an illness occurs, doctors recommend rest or bed rest, rather than jogging in the fresh air or warm-up exercises.

Fat and muscle tissue are different types of tissue. And they are not interchangeable. When exercising, a person expects to increase the volume of muscle tissue and reduce the volume of fat tissue. But this does not mean that any physical activity will achieve this. Protein (protein food) is needed to form and grow muscle tissue, and fat tissue and energy expenditure require fats and carbohydrates, which compete for absorption by the body. What the body chooses is up to it, but if we are talking about maintaining energy and endurance while actively using up fat tissue, then there should be less fatty food than carbohydrate-containing food. If you exercise and continue to eat fatty foods, then the muscles will not increase in size and replace the fat layer. They will increase tone, and the fat layer may also increase. For this reason, sports diets have a strict proportionality in the distribution of food products in the menu for protein, fatty and sweet components.

Starving yourself while doing sports is as harmful as overeating. No one goes jogging, does physical exercise, or loads the body with a full range of sports loads on an empty stomach, just like on a full stomach. It is customary to have a snack an hour before the start of physical activity and drink drinks that allow the body to stock up on water for its use in vigorous exercise. Sports loads "on an empty stomach" can cause a decrease in blood sugar levels, a decrease in pressure, and lead to a painful condition accompanied by dizziness, general weakness, and even loss of consciousness.

Sports loads are always proportionate to body weight and body proportions. It is impossible to pump up a mountain of muscles with regular sports exercises due to the slow growth of muscles and the absence of a certain set of hormones in the body. For sports muscle mass building, special hormonal agents are used in nutrition - muscle growth stimulants - steroids. The use of hormonal drugs in sports, as well as their withdrawal, is accompanied by certain medical supervision, without which irreparable damage to metabolism can be caused.

It is important to know that there is a moderate set of safe sports activities that do not adversely affect health - this is daily walking (at a fast pace), climbing and descending stairs with a small number of steps, bending and squatting without weights, swimming, sports entertainment. A person performs all these physical activities daily, which allows the body to maintain normal health and a toned overall physical condition.
