Validity of selected laboratory and field tests of physical working capacity

The validity of selected laboratory field tests of physical working capacity was investigated. Male college students (N = 44, ages 17-30) were administered a series of laboratory and field tests of physical working capacity (PWC) Laboratory tests included were a treadmill test of [vdot]O max, the pwc, test, the Harvard Step Test, the Progressive-Pulse Ratio Test, the Margaria Test of Anaerobic Power, the All-Out Treadmill Run (10 mph and 8.6% grade), the Harvard Fitness Test (7 mph and 8.6% grade) and 0 debt following the Harvard Fitness Test. Field tests included were the 10-yd dash, the 50-yd dash, Sum 50‘s test, 300-yd run, 600-yd run, 1-mi run, and 12-min run. Significant correlation coefficients were found between [vdot]O max expressed in ml/kg/min and the 12-min run (.90), the 600-yd run (.78), the 1-mi run (-.74), the Balke Test (.77), the All-Out Treadmill Run (.74), the Harvard Fitness Test (.69), the 300-yd run (-.52), the Astrand-Ryhming Test (.62), the Harvard Step Test (.55), pwc (.58), and the Progressive-Pulse Test (-.47). Using Multiple Stepwise Regression with [vdot]O max expressed in ml/kg/min as the criterion measure, the following multiple correlation coefficients were found: from submaximal tests.78; from maximal tests.91; from field tests.91; from other laboratory tests.86; from all tests.92. Body weight and percent lean body mass were found to have little effect on the correlations obtained between [vdot]O max (mil kg/min) and selected work tests. © 1976 Taylor 8 Francis Group, LLC. 2 170 2 2 170 2
