Trunk Muscle Endurance and Flexibility as Determinants of Athletic Performance in Elite Adolescent Tennis Players
Turkey (Türkiye)38 participantsStarted 2025-04-01
Plain-language summary
This study aims to examine how trunk (core) muscle endurance and flexibility relate to athletic performance in elite adolescent tennis players aged 11-18 years. Tennis requires speed, balance, strength, coordination, and repeated high-intensity movements. The trunk region plays an important role in transferring force between the upper and lower body and in maintaining posture and stability during sports activities. However, there is limited research on how trunk physical characteristics influence performance in young elite tennis players.
Participants who actively compete in tennis tournaments and train regularly will complete a set of standardized tests assessing flexibility, trunk muscle endurance, balance, sprint speed, agility, and strength. The results will help researchers understand whether trunk flexibility and endurance are associated with better athletic performance. Findings may guide coaches and health professionals in designing training programs that improve performance and potentially reduce injury risk in young athletes.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
