The Influence of Verbal Cues on Drop Jump Landing Strategies in NCAA Division I Soccer Players

Jump testing to monitor athletic performance and development has become commonplace in the field of strength conditioning. Verbal cues jump tests, such as drop jump, significant effects on metrics movement strategy. The purpose this study was use a force platform analysis investigate landing depth global flexion lower extremity joints at initial impact between maximize height or minimize ground contact time. Another repeat previous investigations influence cueing DVJs time Reactive Strength Index (RSI). Thirty-nine Division I soccer players performed one DVJ (DVJHeight) for maximum another (DVJQuick) quickness. Differences dependent variables were analyzed by Bayesian paired samples t-tests. RSI greatest DVJQuick condition (Meandiff = 0.36 ± 104 (95% HDI: .232, .492). Ground shorter with -0.19 0.028, 95% -0.224, -0.155). less -0.033 0.007, -0.068,.0035). Landing decreased during -0.093 0.018, -0.118, -0.066). Global extremities -0.057 0.025, -0.084, -0.031). resulted large increase due disproportionate decreases (large decrease) compared (small decrease). coincided decrease depth, suggesting stiff strategy increased stretch-shortening cycle intensity.
