In Games and Sports the importance of aerobic potential has been realized by top coaches and everyone tends to spur it up to perform efficiently. A group of 40 male students who were in the age group of 17to 25 years were selected as subjects for the study. They were divided into two groups of 20 each (n= 20) as low and high aerobic capacity groups based on Cooper's 12 minutes run and walk test. Physiological traits were estimated and studied descriptively. The results showed the mean value of lean body mass and total body weight of low aerobic capacity group to be higher than the aerobic capacity group. A significant mean difference was found in hemoglobin content, resting heart rate and vital capacity between the groups.

Stabilometric parameters were compared in sportsmen of various disciplines (biathlon, boat racing, judo, and water polo). A decrease in the role of gravitational factor in sport activity was accompanied by the impairment of balance characteristics, which remained within normal limits of the mean population level.

Changes in nerve conduction after 10-min electroneurostimulation of the posterior surface of the neck were studied. Changes in the parameters of laser-induced potentials obtained during stimulation of C7 dermatome on hands and posterior surface of the neck were found. Decrease in the amplitude and shortening of the component latency were shown. Method of laser-induced potentials was concluded to provide unbiased estimation of the level and peculiarities of analgesic effects of physical factors.

The effects of photostimulation with different colors on α-rhythm amplitude and parameters of variation pulsometry were studied. Green color stimulation modulates human functions: ?-rhythm amplitude increases by 1.06 μV/√Hz (p<0.05) and the index of regulatory systems strain decreases significantly (p<0.05).
