Abstract
Basketball is a high intensity intermittent sport. The aim is to analyze the relationship between the vertical force-velocity profile (FV-v profile) and performance in the 30-15 intermittent fitness test (30-15 IFT), with the repeated sprint ability (RSA), both linear and with changes of direction (COD). 42 basketball players, 32 males (n1=32) and 10 females (n2=10) were evaluated. Measurements of the FV-v profile, the 30-15IFT test, the modified Running-Bassed Anaerobic Sprint Test (RASTm) and the modified Illinois Test with 4 intermittent repetitions were performed, also analyzing the countermovement jump loss (CMJloss) in the latter two. Significant relationships were found between imbalance in the FV-v profile and CMJloss in the modified Illinois test both in the whole sample (r = 0.49, p < 0.001), and in the men´s subgroup (r = 0.67, p < 0.001), although not in women (r = 0.13, p = 0.71). In addition, there was a significant relationship between the velocity achieved in the 30-15 IFT (VIFT) and the fatigue index (FI) in the RASTm (r = -0.33, p < 0.05). Optimization of the FV-v profile has a positive influence on CMJloss in RSA with COD. Specific endurance exerts a small influence on RSA without COD.
