Actuality of Research. Scientific works proved that the greater the volume of the lungs, the better the physical abilities of athletes. So researching of the functional state of organism, namely the level of lung capacity of volleyball players is very important. The aim of the Researching. Determining of the level of lung capacity, forced air volume in 1 second and peak expiratory flow rate in volleyball qualifications. Results. The average rate of lung capacity of volleyball players is – 3,98 l, Forced air volume in 1 second – 3,32 liters, peak expiratory flow rate 5,77 – l/sec. Conclusions. The results of researching indicate that the level of vital capacity in girls is rather higher. So volleyball players (girls) have a high level of fitness of the body, providing adaptation to hight loads and hight endurance.
Studies of cardioselectivity and partial agonist activity in beta- adrenoceptor blockade comparing effects on heart rate and peak expiratory flow rate during exercise.
