Abstract

The purpose of this study was to investigate the criterion validity of isokinetic leg press Power-Force-velocity (P-F-v) parameters. Forty elite athletes with diverse sporting backgrounds performed a maximal vertical squat jump test and an isokinetic leg press P-F-v profile test. The isokinetic leg press P-F-v profile consisted of leg-extension against 4 given velocity conditions: 0.1, 0.3, 0.7, and 1.2 m/s. Criterion validity was evaluated using correlation between squat jump height and each isokinetic P-F-v parameter (F₀, v₀, P_max and, Sfv). Nearly “good” (r > 0.815) correlations were found for P_max, whereas correlations between the remaining P-F-v parameters ranged from “poor” to “impractical” (r = 0.702– 0.159). This result may fit the previous assumption of P-F-v profiles, that individuals express variable contributions of F₀ and v₀ for similar P_max values. Consequently evaluating criterion validity for these parameters (F₀ and v₀) is likely difficult would be contrary to this P-F-v assumption.
