Relationship between record time and maximal oxygen consumption in middle-distance running.
The relationship between record time (tr) 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 tr and VO2max were inversely related. The relationships tr = f(VO2max) have been fitted by two exponential equations: tr (1500 m) = 698e-0.0145VO2max; tr (800 m) = 272e-0.011VO2max; P less than 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 tr were highly correlated to measured tr (P less than 0.001), it was concluded that the relationships tr = f(VO2max) can be interpreted on the basis of the model described in this study.
