Effect of Increasing External Loads on Countermovement Jump Landing Kinetics between NCAA DI Women's Soccer and Gymnastics on Land vs in Water

摘要: The purpose of this study was to compare the effect differing loads on landing kinetics land, and in aquatic conditions. Twenty four NCAA DI athletes volunteered for twelve female soccer players gymnasts. Participants performed three jumps with external both land environments. External were body weight (BW), BW*1.1, BW*1.2, BW*1.3 applied via a weighted vest. All conditions added based upon participants BW land. Kinetic measures peak force, rate force development, impulse phase plyometric countermovement jump. Data collected waterproof force-plate. Results analyzed using three-way repeated 2x2x4 ANOVA. There no significant difference any result sport. Aquatic environments reduced impact by 50.7%, development 53.5%, 38.6%. Increasing load did not produce differences or but significantly higher (p=0.000). In an environment increasing produced all kinetic values. results agree previous studies. loaded show increased over unloaded jumps, decreased jumps. Adding may utilized increase kinetics, while remaining under values plyometrics. EFFECT OF INCREASING EXTERNAL LOADS 3
