Effect of Blueberry Supplementation on Liver Enzymes, Muscle Injury and Respiratory Parameter in Football Athletes: A Eight-Week Training Study

Turkey (Türkiye)36 participantsStarted 2025-01-05

Plain-language summary

Abstract Background and objective: Regular Exercise causes physiological changes in the body. As a result, its impact on liver enzymes and muscle injury is unknown. The purpose of this study was to look into the effect of blueberry supplement taken in addition to football training on athlete muscle injury, liver enzymes and respiratory parameter. Methods: The present study comprised 36 male football players who volunteered for the study. The participants were divided into three groups: a Control Group (CG) (n=12), which performed only football training; a Supplementation Group (EG) (n=12), which received blueberry supplementation in addition to football training; and a Supplementation + Exercise Group (SEG) (n=12), which received blueberry supplementation and 20 minutes of exercise in addition to football training. A eight-week training program was implemented to the athletes three days per week in our study. The athletes' blood was drawn twice before and after training. The athletes' markers of muscle injury and liver enzymes were measured as a result of blood samples taken. The SPSS package program was used to examine the study's data.

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.
