Abstract

This article deals with issues that are aimed at the organization of strength training. First of all, it is necessary to note significant differences between women and men in terms of strength. In women, they are 15-20% lower than in men. Women have a lower tendency to gain muscle mass. This is primarily related to the hormonal background, since the male hormone testosterone is responsible for the growth of muscle mass, and its amount in the body of women is many times smaller than that of men. At the same time, women's ability to display strength indicators of leg muscles is close to men's. Experts in age-related physiology note that at the age of 40-45, reverse processes begin in a woman's body. The main metabolism slows down, the productivity of various organs and systems decreases, the possibility of various pathological processes, chronic diseases, etc. increases. In connection with the decrease in the hormonal background, negative changes areobserved in all organs and systems of the body. Blood pressure often rises, a tendency to osteoporosis appears, fat metabolismis disturbed, which often leads to an increase in body fat. There are significant changes in the respiratory system, the vital capacity of the lungs decreases, the mobility of the chest decreases. After 40 years, there is a significant decrease in musclestrength in women. The elasticity of muscles, tendons, and joint performance is lost. At the same time, muscle tone decreases, which leads to negative changes in posture.
