Consecutive changes during standartised cardiopulmonary test in basketball players

The purpose of the study was to determine the dynamics of cardiopulmonary and metabolic response of trained basketball players during different stages of exhaustive exercise lest. A total of 42 male athletes were studied. They performed incremental multistage (50W each 2 min) exercise lest until exhaustion. During the lest, the expired air was analyzed using breath-by-breath VMAX229 System. Parameters of Ventilation, heart rate, power, indices of gas exchange were measured during the tests. Samples were formed for each 30 s interval. All samples were checked according to the Kolmogorov-Smirnov criterion and Standard grouping into classes was used; the degree of freedom was established according to the normal distribution Standard (k=m-p-l). Confidence intervals were calculated for samples similar to normal (95% level, p<0.05 considered sufficient).The results of this study suggest that the increase in VO2 is a * linear progression, which approximately corresponds to the function VO2~4.68+0.14*P in relation to load (VO2=P/8) or VO2~7,34+0,04*T in relation to time (VO2~t(s)*19. Graphic expression of cardiopulmonary and metabolic variables is useful nomograms for the routine assessment of response during exercise in players of invasion games.
