This study investigated countermovement jump (CMJ) strategies among NCAA Division 1 athletes and explored key variables associated with jump height. A total of 69 athletes (38 male, 31 female) from basketball and volleyball teams completed three or more CMJ trials on force plates during their regular neuromuscular monitoring. Using repeated-measures correlation analysis, we examined the relationships between various force-time variables and jump height across different sports and sexes. The results demonstrated very strong correlations between concentric peak velocity and jump height across all groups (r > 0.987). In addition, female athletes exhibited higher correlations between force-related parameters (concentric peak force, relative concentric peak force, and relative concentric mean force) and jump height compared to male athletes. Furthermore, no significant differences in force asymmetry were observed between sports or sexes. These findings indicate that concentric peak velocity serves as a key indicator of jump performance while emphasizing the importance of considering the interaction between force, time, and velocity, rather than focusing solely on peak force production. This research provides valuable insights for developing sport-specific training programs and monitoring jump performance in collegiate athletes, highlighting the necessity of individualized assessment and training approaches rather than assuming specific physical qualities are associated with particular populations.
