The first studies about the link between body activity and overall health started in the 1950’s, but it was 30-40 years later, when the overwhelming scientific evidence for the positive effect of activity and sport and the health was found. Various studies have shown the correlation between regular physical activity and the prevention of certain illnesses and health conditions, such as: diabetes, cardiovascular disease, hypertension, osteoporosis, depression, obesity and cancer.
Research has shown that when young people practice sports on a regular basis, their bone development and proper growth is healthier, also the lung and heart functions improve. For women, engaging in regular exercise and other physical activity help reduce the risk and effects of osteoporosis and reduces the risk of hip fractures. Elderly people who stay active keep up their quality of life and their independence. The heart beats harder during exercise, and thus does its own exercise, which keeps it healthy and reduces the risk of cardiovascular problems.
Experiments show that not only does sport lower the weight and hypertension, but it can help lower the bad cholesterol levels as well. Regular training helps improve the blood circulation, improves the bone density and makes the muscles stronger and more toned.
Another positive effect of regular exercise of the human health has been found by the World Health Organization. It links sports with improved mental health in people who suffer from different psychological disorders. Regular exercise makes people fitter and makes their bodies more toned, which imminently has an effect on their self- consciousness, confidence and their self-perception. This means that regular exercise can help treat or prevent depression too.
Sports can help people develop their concentration, cognitive and motor skills, coordination as well as the ability to communicate and work along with other people, especially in team sports. Of course, the studies have found that the physical activity’s effect on the health is also influenced by the diet, the intensity of the activities, the type of climate, the sleep patterns and even wearing the appropriate athletic footwear and clothing worn during the physical activity.
Using sports and regular activity as a preventive method against diseases of different kinds is actually a very cost-effective method, and policy which should be promoted not only in the Western world but also in the developing countries.
Overall, playing sports promotes a healthier lifestyle. Not only does it prevent a number of diseases and harmful conditions, but it brings positive energy, self-esteem, helps improve the discipline, teamwork as well as goal setting.
