Effects of Cognitive Training on Executive Functions and Decision-Making in Adolescent Female Volleyball Players
Turkey (Türkiye)50 participantsStarted 2026-05-02
Plain-language summary
This randomized controlled trial aims to evaluate the effects of a four-week tablet-based cognitive training program on executive functions and on-court decision-making performance in adolescent female volleyball players. Fifty licensed female volleyball players aged 12 to 14 years were randomly assigned to either an intervention group or a control group. The intervention group received cognitive training three times per week in addition to routine volleyball training, while the control group continued routine training only. Executive functions were assessed using the Stroop Test, Trail Making Test-A, Go/No-Go Test, and 2-Back Test. Volleyball-specific decision-making performance was evaluated using a video-based temporal occlusion test. The study investigates whether improvements in executive functions following cognitive training transfer to sport-specific decision-making performance.

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?
