Change of direction ability (CODA) is vital for team sport athletes, especially soccer. However, there is little evidence relating the association of CODA and jumping ability in female soccer players.

PURPOSE: The aim of this study was to assess the relationship between CODA and loaded and unloaded vertical jump performance among NCAA Division I female soccer players.

METHODS: 14 female soccer players (age 21±0.9yrs, height 168.5±5.7cm, weight 67.3±6.9kg) were volunteered to participate in this study. A 5-5 COD test was used to evaluate CODA; athletes were required to sprint 5 m, perform a 180° turn and sprint back to the starting line. Two sets of timing gates were used to assess athletes’ 3m acceleration time (3mAcc) and total time (TT). Countermovement jumps (CMJ) and static jumps (SJ) with loaded (20kg barbell) and unloaded (0kg PVC pipe) conditions were performed on a force plate. Jump variables included: jump height (JH), peak force (PF) and peak power (PP). The relationship of CODA and vertical jumps was assessed using Pearson correlation coefficients.

RESULTS: Strong statistically significant relationships were found between 3mAcc and TT (r=0.67, p<0.01), TT and SJ JH (0kg, r= -0.59, p<. 05; 20kg, r= -0.541, p<0.05). No relationships were found among 3mAcc and other jumps variables.

CONCLUSION: The results from this study indicated at female soccer players who jumped higher during loaded and unloaded SJ had superior CODA. The results also showed the female soccer players who sprint faster during the first 3m had better CODA. Therefore, vertical jump height might be a useful tool to access female soccer players’ CODA at the NCAA Division I level.
