The growth of the human body ends at the age of 25, and the aging process begins immediately. To slow down or stop it altogether is a dream not only of scientists and philosophers who have been trying for centuries to find the “elixir of youth”, but also of each individual person. About a century ago, the science of gerontology arose, studying the biological, social and psychological aspects of human aging, its causes and ways to deal with it. A lot of scientific and pseudo-scientific theories of aging have arisen, over which whole gerontological institutes work, created in almost all countries of the world. There are a lot of theories describing the causes of aging – a change in the regulation of gene activity, a decrease in the synthesis of intracellular regulators of plasma membranes, a decrease in the length of telomeres (end sections of chromosomes), the concept of stress-age syndrome, etc. Continue reading
The topic of losing weight is, without exaggeration, one of the most popular topics in communication – both physical and virtual, and in all age groups. The inability of most people to observe moderation in food and to properly compose their own diet leads to a gradual (and sometimes quite fast) weight gain, which must be periodically “driven off”. Few manage to keep their weight at a constant level of a slim figure, and here heredity, family traditions in nutrition, own aesthetic views, lifestyle, and, of course, physical education play an important role. Unfortunately, some physical exercises cannot cope with the problem of excess weight, and it must be solved in conjunction with other measures.
There are a lot of recommendations on how to lose weight. You can “sew up” your mouth by sharply limiting the diet, as the great ballerina Maya Plisetskaya advised; you can completely stop eating for a while – the benefits of therapeutic fasting are undeniably proven. Continue reading
Engaging in physical education is not only useful, but also fashionable. Today, young people and middle-aged people regularly visit fitness clubs, train in sections or on their own. Someone trains every day, someone once a week, and each sets its own tasks – either to build muscle, or to gain a slender figure, or simply to maintain and strengthen health. It is useful to know in this case that according to the Scandinavian recommendations on nutrition and a healthy lifestyle (NNR), which are the most authoritative for the Nordic countries (including Russia), adults need to spend at least 150 minutes a week on moderate loads or more than 75 minutes per week for high-intensity loads. This means that you need to train at least two to three times a week. If this doesn’t work out like this, you can gain the necessary level of physical activity with daily morning exercises (at least 15-20 minutes) and walking, controlled by a pedometer (10 thousand steps per day).
