Reactivity of the Reproductive System During Physical Activity

Abstract

Hormones play a very important role in the functioning of the human body. These
substances stimulate the activity of certain cells and systems of the body. Hormones are produced
by endocrine glands and certain tissues. Among the wide range of hormones, anabolic and
catabolic hormones are of particular importance. Catabolism is the process of metabolic
breakdown of cells and tissues, as well as the breakdown of complex structures with the release of
energy in the form of heat or in the form of adenosine triphosphate. Catabolic processes provide a
large amount of energy. Anabolic processes are the opposite of catabolic processes. Anabolic
processes refer to the processes of creating cells and tissues, as well as substances necessary for
the functioning of the body. Regenerative processes and anabolism of muscle tissue largely depend
on the level of growth hormone, insulin and testosterone in the blood plasma. Physical activity
significantly increases the concentration of many hormones in the blood plasma, and not only
immediately during exercise. From the beginning of exercise (for example, close to maximum
power), in the first 4-10 minutes, the concentration of various hormones and metabolic products
changes spontaneously. Thus, with the start of exercise, the concentration of lactic acid in the
blood increases. And the concentration of glucose begins to change inversely with the
concentration of lactic acid. The level of somatotropin in the blood increases with the increase in
the time of physical exercise.
