Abstract

The purpose was to determine the relationship between two measures of lower-limb explosive power (LLEP) and establish the relationship between these measures and physical match performance (PMP) in Division II female collegiate soccer players (N = 24). Countermovement jump (CMJ) height (using a switch mat) and a 5-jump test (5JT) for distance were measured. PMP was measured by the Yo-yo intermittent recovery test level 1 (YYIRTL1). Hypotheses were: 1) 5JT would significantly relate to CMJ, and 2) the relationship between 5JT and YYIRTL1 would be stronger than the relationship between CMJ and YYIRTL1. Scores on the 5JT (910.0 ± 59.7 cm) and CMJ (39.7 ± 4.3 cm) were related (r = .71, p .05). No significant relationship was found for 5JT or CMJ with YYIRTL1 (r = .20, p .05; r = .11, p .05, respectively). 5JT is a valid measure of LLEP in female soccer players. The sex of the athlete, limitations in measurement methods for LLEP, the location of participants on the spectrum of performance and/or restriction of range in values may explain findings of the current study relevant to existing literature. Also, validation of YYIRTL1 is based on high-intensity running in a match, and the contribution of LLEP to this may be small. Alternatively, powerful participants, who are less resistant to fatigue, may have performed poorly on YYIRTL1 due to its fatiguing nature. The 5JT validly measures LLEP in soccer; LLEP does not explain variance in PMP in Division II female soccer players.
