[Psychophysiological states in humans with different levels of adaptation to muscular activity].

The influence of straight muscular activity to peculiarities of forming ofpsychophysiological states in humans has been studied. Two groups of sportsmen with different levels of adaptation to muscular activity were investigated. The first group composed of the sportsmen with higher level of adaptation to muscular activity (27 members of Ukrainian national team of Greco-Roman wrestling, aged 18-26), the second group contained the sportsmen with the average level of adaptation to muscular activity (24 sportsmen, average qualification, student of specialty gymnasium, aged 18-26). The results showed that psychophysiological states in humans with higher adaptation level to muscular activity are characterized by more determined organization of information processing system and heart rate regulation compared to humans with simple adaptation level. In addition, in sportsmen who have higher level of adaptation to intensive muscular activity the balance with vagus-sympathetic tonus mechanisms of vegetative regulation of heart rate is showed.
