RELATIONSHIP BETWEEN RECORD TIME AND MAXIMAL OXYGEN-CONSUMPTION IN MIDDLE-DISTANCE RUNNING

The relationship between record time (t(r)) and maximal oxygen uptake (VO2max) has been examined in 69 male physical education students who had taken part in 800-m and 1500-m footraces. It was found that t(r) and VO2max were inversely related. The relationships t(r) = f(VO2max) have been fitted by two exponential equations: t(r)(1500m) = 698e-0.0145 VO2max; t(r)(800m) = 272e-0.011 VO2max; P < 0.001. A mathematical formulation of the energy conservation principle in supramaximal running, based on the exponential increase of the oxygen uptake as a function of time with a rate constant of 0.025 s-1 has been applied to the tr calculation from VO2max. As calculated t(r) were highly correlated to measured t(r) (P < 0.001), it Was concluded that the relationships t(r) = f(VO2max) can be interpreted on the basis of the model described in this study.
