Abstract: (220 Views)
Background. Jump landing tasks are frequently employed as a non-specific tool to quantify the capabilities of the lower extremity performance and athletes' injuries.
Objectives. This study aimed to investigate the relationships between jump height (JH) and ground contact time (CT) in countermovement jump (CMJ) and drop jump (DJ) with assessment indicators such as reactive strength index (RSI), eccentric phase rate of force development (ERFD), peak rate of force development (PRFD), average velocity (EV), amortization phase time (AT), peak ground reaction force (PF), concentric phase average force (CAF), and vertical stiffness.
Methods. This study employed a cross-sectional design, with 23 participants completing CMJ and DJ tests. Ground reaction force and center of mass displacement data were captured using a motion system and force platforms. Paired-sample t-tests were used to compare differences between CMJ and DJ in JH, CT, ERFD, RSI, and CAF. Spearman rank correlation analysis was conducted to examine the correlation between vertical stiffness and other variables, while Pearson product-moment correlation was used to identify correlations among other variables.
Results. JH was comparable between CMJ and DJ (p=0.14), whereas significant differences were noted in CT (p<0.001), ERFD (p<0.001), RSI (p<0.001), and CAF (p=0.01). In CMJ, significant positive correlations were identified between JH and RSI, PF, and CAF (RSI: r=0.44, p=0.036; PF: r=0.48, p=0.022; CAF: r=0.55, p=0.007). Moreover, CT exhibited a significant negative correlation with RSI, ERFD, and PRFD (RSI: r=-0.66, p=0.001; ERFD: r=-0.47, p=0.025; PRFD: r=-0.44, p=0.034) and a significant positive correlation with AT (p>0.05). During DJ, JH was significantly positively correlated with CAF and RSI (RSI: r=0.76, p<0.001; CAF: r=0.66, p<0.001), whereas CT was significantly negatively correlated with RSI (r=-0.48, p=0.021). Notably, increasing the drop height altered these relationships.
Conclusion. These findings collectively reveal that CMJ and DJ differ in influencing factors, suggesting that athletes should tailor their training strategies according to the type of jump.

APPLICABLE REMARKS
APPLICABLE REMARKS
- For athletes primarily engaged in countermovement actions at ground level, if the goal is to improve JH, the focus should be more on strength training, followed by SSC capacity.
- If the priority is enhancing movement speed, SSC capacity should be prioritized first, followed by explosiveness.
