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.

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.
