• Conditions: Sports; Basketball; Strength Training
• Interventions: Other: Resistance training based on DSI value; Other: Normal training group

• Registration Number: NCT06094075
• Lead Sponsor: University of Primorska

Brief 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.
