This paper describes experimental studies aimed to restore the physiological functions of model animals after a heavy physical load using biologically active substances in their diet. The findings of this study may be applied in power training. The paper suggests using biologically active substances in the diet of animals to maintain their internal environment after maximum physical exertion. The conducted experiments showed that bioactive supplements of different nature optimized the homeostasis of the laboratory animals. It positively affected their skeletal and heart muscles, lung tissue, liver and kidneys, where immunity and blood cells develop. Although the swimming test at the beginning of the experiment showed that mice and hamsters had approximately the same indicators of physical endurance, by the end of the experiment, the swimming time of the experimental group animals was significantly longer. The animals receiving pantocrine turned to be stronger. Their interval time increased by 267 seconds (Р≤0.05) while the swim time of animals consuming may chang rose by 96 seconds (Р≤0.05) compared to the control. Male hamsters consuming lemongrass tincture showed the maximum efficiency, exceeding the control by 21.3 minutes (P≤0.001), animals receiving drone brood overran by 0.5 minutes (Р≤0.01). Heart muscle of animals fed with pantocrine and lemongrass seed tincture at physical load had fewer dystrophic changes in muscle cells. The wall structure of most vessels did not have obvious pathological changes. Consequently, greater physical endurance in mice administered pantocrine and hamsters given lemongrass tincture is mainly due to better coordination of motor and vegetative functions and the functional stability of the body systems that ensure oxygen delivery to the working muscles.
