Treadmill and track running comparisons were made on eight track athletes. Oxygen uptake (o2) during steady-state and maximum aerobic power (o2max) were measured in a discrete series of three speeds, and at maximal effort. Running speeds were always in sequence from slowest to fastest. Expired air was collected from the runner by the Douglas-bag method, and analyzed by the Lloyd-Haldane technique. Neither o2max nor aerobic requirements of running were significantly different in track and treadmill determinations. There were several correlations: 1) o2max with body weight (r = .83 P < .02), 2) treadmill and track determinations of o2max (r = .95, P < .01) and 3) o2ml/kg with running velocity m/min (r = .91, P < .01) where the regression was linear and may be represented by the equation Y = 5.36 -r 0.172X, where Syx = 2.7 ml02/kg. It is concluded that treadmill determinations of oxygen uptake may be validly applied to track running in calm air within the range of 180 … 260 m/min. |
