Abstract | The aim of the study was to investigate associations and differences between dynamic strength index (DSI) and multi-directional jumping, linear and curvilinear sprinting and change of direc-tion (CoD). Highly trained basketball players (n = 44) performed 20-m linear sprint, 20-m 3-point line (curvilinear) sprint, countermovement jump (CMJ), drop jump (DJ), bilateral horizontal jump, unilateral horizontal jump, lateral jump, basketball specific lateral jump and isometric mid-thigh pull (IMTP). The results showed weak to moderate associations between IMTP performance and horizontal jump, lateral jump and curvilinear sprint (r = −0.33-0.41; p < 0.05). No correlations were found between CMJ peak force and performance variables, while weak correlations were observed between DSI and unilateral horizontal jump (r = −0.36; p < 0.05), lateral jumps, linear sprint and CoD deficit (r = −0.37, −0.38; p < 0.05), showing that lower magnitude of DSI is associ-ated with better performance in those tests. Additional analysis revealed that the low DSI sub-group had the highest IMTP peak force, while high DSI subgroup had the highest CMJ peak force. The low DSI group showed better performance in vertical, horizontal and lateral jump, while no significant differences were observed in DJ and curvilinear sprint performance compared to other groups. The findings indicate that athletes with lower DSI values exhibit superior physical per-formance, suggesting that a strength-oriented training approach may be beneficial for basketball players, Due to ballistic nature of basketball, more maximal strength training is required to op-timize the DSI ratio in basketball players. Additional studies are needed to determine the precise benchmarks for navigating training based on DSI values. |
