[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).

[Sexual dimorphism of the psychophysiological indices in sportsmen of higher qualification].

To determine the influence of sexual dimorphism on mental characteristics in elite athletes, 24 sportsmen (18-27 years old) (17 men and 7 women members of Ukrainian National Judo Team), 20 sedentary men and 20 sedentary women (20-29 years old) were studied. Results obtained confirmed significant difference of sexual dimorphism indices in athletes and sedentary people. It was determined that sexual dimorphism manifestations in athletes were as follows: (1) short memory capacity (62.

[Functional state of the body and mental capability in humans of various ages].

The aim of investigation was to studied of functional state and mental capability of human in different age. The 150 women and 125 men in five age-groups: 13-18, 19-29, 30-39, 40-49, 50-60 [symbol: see text] were examined. The mental capability was modeled by special computer's test.

[The characteristics of autonomic regulation in persons with different levels of mental work capacity].

The aim of the study was investigation of efficiency of mental activity in people with different types of vegetative regulation. The 32 operators Chernobyl atomic station aged 26-54 were examined. The mental activity was studied by two computer's tests.

[The age-related characteristics of human mental work capacity].

The aim of investigation was to study the ageing peculiarities of human mental working capacity with mathematical models. Were examined 150 women and 125 men in five aged groups: 13-18, 19-29, 30-39, 40-49, 50-60. The human mental activity was presented with special computer's tests.

[The characteristics of visual information processing in persons of different ages].

Remarked the information of the computer operators (fifty persons aged from 18 to 67 years) was studied under conditions of the modelled computer operation. The results obtained show that the process of remarked the information of operators is characterized by a decrease in professional working capacity due to an overstrain of physiological reserves of an organism. Dynamics of their ageing involution includes four stages: professional training (age 18-21), maximal professional working capacity (age 26-28), professional ageing (age 29-40), and accelerated professional ageing (age after 40).

[Study on transitional processes of the regulation of the heart rate in man exposed to strenuous muscular activity].

Physical work (gradually increasing from initial 20 W + additional 20 W each minute up to the moment of failure to perform any work) was performed by 38 sportsmen and 35 non-sportsmen aged 18-25. The cardiac rhythm was registered based on two parameters: the heart rate and heart rate dispersion. The urgent adaptation to strenuous muscular activity characterizes the transitional process of an open outline of the cardiac rhythm regulation.
