【 摘 要 】

Background: The vertical jump task is a critical component of success in volleyball. Eachposition on the court has its own physical demands and has differing levels of vertical jumptask demands. Objective: Thus, the objective of this investigation was to compare vertical jumpperformance between the two positional groups using the countermovement jump (CMJ) andsquat jump (SJ). Methods: Using an observational cross-sectional study design, nineteen NCAADivision I female volleyball athletes participated in this investigation. Participants first performedthree CMJ trials followed by 3 SJ trials on a force platform. Jump height, peak and mean netpropulsive forces, and time to take off were calculated for both the CMJ and SJ. Reactive strengthindex modified and propulsive duration were additionally calculated for the CMJ and averageRFD for the SJ. Independent sample t-tests were performed comparing positional groups on eachvariable of interest with Hedges g effect sizes additionally calculated. Results: No statisticallysignificant differences (p < 0.05) were found between any of the variables of interest in the CMJthough moderate effect sizes were seen in jump height (g =0.78). No statistically significantdifferences were present in the SJ though moderate effect sizes were seen in RFD (g = 0.65),mean propulsive force (g = 0.79) and peak propulsive force (g = 0.66). Discussion: As the verticaljump task is a critical task for high-level performance in both positions, and the no differencesseen between groups, training programs should be designed to improve jump performance withspecial attention to the individual athletes’ needs rather than the specifics of the playing position.
