Effects of Taurine Supplementation on Repetitive Sprint Performance and Exhaustion Time in College Students Under High-Temperature and High-Humidity Conditions

China16 participantsStarted 2024-12-01

Plain-language summary

This study is designed to evaluate the effects of acute pre-exercise taurine supplementation at different doses on the performance of college students during exhaustive exercise and subsequent repetitive sprint (RS) activities in a high-temperature, high-humidity environment. Sixteen college students (8 male, 8 female) will participate in a single-blind, randomized, crossover-controlled trial. Participants will be divided into four groups: high-dose taurine (6g), medium-dose taurine (4g), low-dose taurine (1g), and placebo. Key performance metrics such as peak power (PP), mean power (MP), fatigue index (FI), exhaustion time (ET), reverse vertical jump height, heart rate (HR), blood lactate (BLA), and ratings of perceived exertion (RPE) will be measured. The objective of this study is to assess how taurine supplementation influences exercise performance under these challenging environmental conditions. This study will help to better understand taurine's potential effects on exercise performance and contribute to nutritional strategies for athletes exposed to extreme conditions.

Inclusion Criteria: * School students * Aged between 18 and 28 years * No exercise-related risk, as indicated by a "no" response to all questions in the Physical Activity Readiness Questionnaire (PAR-Q) * No taurine-based supplements consumed in the last month. Exclusion Criteria : * Individuals who do not meet the inclusion criteria * Individuals with a history of cardiovascular issues, respiratory problems, or any condition that may impair exercise performance * Participants who did not provide a "no" response to all questions in the Physical Activity Readiness Questionnaire (PAR-Q) * Participants who consumed taurine-based supplements in the month preceding the study.

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.

What they're measuring

Change from Baseline in Peak Power (Watts)

Timeframe: Measured at the end of each sprint on Day 1 and Day 7.

Change from Baseline in Mean Power (Watts)

Timeframe: Measured after all 6 sprints on Day 1 and Day 7.

Change from Baseline in Fatigue Index (%/s)

Timeframe: Measured across all 6 sprints on Day 1 and Day 7.

Change from Baseline in Exhaustion Time (seconds or minutes)

Timeframe: Measured at the point of exhaustion during exhaustive exercise on Day 1 and Day 7.

Change from Baseline in Blood Lactate Levels (mmol/L)

Timeframe: Measured at baseline (pre-exercise), immediately after exercise, and at specific recovery intervals on Day 1 and Day 7.
