Stress Response to Physical Exercise in Rats with Alimentary Obesity

Stress response to physical exercise was studied in rats with alimentary obesity with and without caloric diet restriction. Daily excretion of corticosterone, progesterone, and testosterone, weights of internal organs, and serum levels of glucose, free fatty acids, triglycerides, corticosterone, and testosterone were estimated. Stress response to moderate exercise in rats with alimentary obesity was associated with predominance of anabolic influence of testosterone over the catabolic effects of corticosterone, which promoted the increase in the weight of reproductive organs. Exposure to physical loads against the background of restricted ration potentiated the response of the adrenocortical system and reduced the concentration and anabolic effects of testosterone.
