Neuromuscular Fatigue Assessment in Youth Soccer

Turkey (Türkiye)18 participantsStarted 2025-06-15

Plain-language summary

This clinical trial investigates neuromuscular fatigue and recovery responses following a standardized soccer-specific fatigue protocol in trained young male soccer players. The study compares the sensitivity of different neuromuscular performance assessments, including the countermovement jump (CMJ), isometric mid-thigh pull (IMTP), and isometric hamstring 90-90 (IH90-90) tests, for detecting fatigue and recovery over time. The main questions the study aims to answer are: * Which neuromuscular assessment is most sensitive for detecting fatigue following soccer-specific activity? * How do force production characteristics change immediately after exercise and during recovery? * Do single-joint and multi-joint isometric assessments demonstrate different recovery patterns? Participants complete a standardized soccer simulation fatigue protocol and perform neuromuscular performance tests before exercise, immediately after exercise, and 24 and 48 hours following the protocol. The findings may help improve fatigue monitoring strategies during congested training and match schedules in soccer players and support approaches aimed at reducing injury risk.

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
