Clinical Trial Summary

The goal of this randomized controlled trial will be to determine the effectiveness of the dynamic strength index (DSI) in optimizing training programs to improve physical performance proxies (sprinting, jumping, and CoD) in basketball players. Subjects will be randomly allocated to one of two groups: the intervention group and the control group. Measurement and intervention will occur during a 7-week in-season period, right before the play off starts. Throughout this period, all participants will engage in an average of 10 hours of basketball training per week, which will comprise 5 basketball sessions and 2 strength training sessions. In addition, they are anticipated to play 2 games weekly. A pre-test will be performed one week before the first training session, and post-tests will be performed in the week after the training sessions have finished. Athletes will perform both testing sessions at the same time of the day (± 2 hours). Each athlete will perform a 20-m sprint test, with timing gates positioned at every 5 m distance, a 505 CoD test, countermovement jump (CMJ), and isometric mid-thigh pull (IMTP). Based on CMJ peak force and IMTP peak force data, we will calculate DSI. Based on the average DSI value, the participants in the intervention group will be divided into two groups - strength group and ballistic group.

Intervention

Other:
• Resistance training based on DSI value
The intervention consist of modifying the ongoing resistance exercises. Those with low DSI values will perform ballistics, explosive exercises. Those with high DSI will perform heavy-load training. The resistance training program will consist of 2 sessions per week for 5 weeks (10 sessions in total). The sessions will be separated by a minimum of 48 hours. The strength training group will consist mostly of exercises with high load, whereas the ballistic training group will perform ballistic exercises with low load or without any additional load. The training principle will be the same for both subgroups, consisting of 3 exercises per training session and a total of 6 exercises per week, with four of the exercises being bilateral, one unilateral, and one quasi-unilateral (Bulgarian split squat and scissor jumps).
• Normal training group
The participants will do a general training program (not based on DSI values). The resistance training program will consist of 2 sessions per week for 5 weeks (10 sessions in total). The sessions will be separated by a minimum of 48 hours. The strength training group will consist mostly of exercises with high load, whereas the ballistic training group will perform ballistic exercises with low load or without any additional load. The training principle will be the same for both subgroups, consisting of 3 exercises per training session and a total of 6 exercises per week, with four of the exercises being bilateral, one unilateral, and one quasi-unilateral (Bulgarian split squat and scissor jumps).
