The counter-movement jump (CMJ) is frequently utilized by strength and conditioning professionals working with athletes, given its relationship to a multitude of performance variables associated with success in sports.
To examine characteristics of CMJ performance between NAIA and NCAA Division I male and female athletes.
Archival data for 275 student athletes from two NCAA Division 1 universities (NCAA DI; males = 84, females = 74) and one NAIA university (NAIA; males = 66, females = 51) were utilized for this analysis. The CMJ was performed utilizing a dual single axis (Pasco PS 2141 plates, sampling rate 1000hz unfiltered) force platform system. A 2 × 2 multivariate analysis of variance (MANOVA) was used to determine whether significant differences in the three dependent variables of VJ height (cm), concentric RPD-100ms, and peak power existed between athletes at different playing levels.
A MANOVA revealed significant differences based on sex and competition level in the dependent variables measured (Wilk's Lambda = 0.908, (3,259) = 8.732, < .001, partial η = .092).
The findings of this study revealed that females at the Division I level achieved significantly greater jump heights, peak power and concentric RPD-100ms compared to females at the NAIA level. Division I males displayed significantly higher peak power than their NAIA counterparts.
反向纵跳（CMJ）常被力量与体能训练专业人员用于与运动员合作，因为它与众多与运动成功相关的表现变量有关。
研究美国全国大专体育协会（NAIA）和美国全国大学体育协会第一分区（NCAA Division I）男女运动员的CMJ表现特征。
本分析使用了来自两所NCAA第一分区大学（NCAA DI；男性 = 84人，女性 = 74人）和一所NAIA大学（NAIA；男性 = 66人，女性 = 51人）的275名学生运动员的存档数据。使用双单轴（帕斯科PS 2141板，采样率1000赫兹，未滤波）力平台系统进行CMJ测试。采用2×2多变量方差分析（MANOVA）来确定不同比赛水平的运动员在垂直跳高度（厘米）、向心RPD - 100毫秒和峰值功率这三个因变量上是否存在显著差异。
多变量方差分析显示，在所测量的因变量中，基于性别和比赛水平存在显著差异（威尔克斯Lambda = 0.908，（3,259） = 8.732，P <.001，偏 eta方 = 0.092）。
本研究结果表明，与NAIA水平的女性相比，第一分区水平的女性在跳高度、峰值功率和向心RPD - 100毫秒方面显著更高。第一分区的男性比NAIA的男性表现出显著更高的峰值功率。
