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

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.

Interventions

DIETARY_SUPPLEMENT

High-Dose Taurine Supplementation (6g)

Participants will receive taurine supplementation at a high dose of 6g. The taurine will be provided in powder form, dissolved in water, and administered 30 minutes prior to exercise. This intervention is designed to evaluate the effects of high-dose taurine supplementation on exercise performance, fatigue resistance, and recovery under high-temperature and high-humidity conditions.

DIETARY_SUPPLEMENT

Medium-Dose Taurine Supplementation (4g)

Participants will receive taurine supplementation at a medium dose of 4g. The taurine will be provided in powder form, dissolved in water, and administered 30 minutes prior to exercise. This intervention is designed to evaluate the effects of medium-dose taurine supplementation on exercise performance, fatigue resistance, and recovery under high-temperature and high-humidity conditions.

DIETARY_SUPPLEMENT

Low-Dose Taurine Supplementation (1g)

Participants will receive taurine supplementation at a low dose of 1g. The taurine will be provided in powder form, dissolved in water, and administered 30 minutes prior to exercise. This intervention is designed to evaluate the effects of low-dose taurine supplementation on exercise performance, fatigue resistance, and recovery under high-temperature and high-humidity conditions.

DIETARY_SUPPLEMENT

Placebo (0g Taurine)

Participants will receive a placebo, consisting of an inactive substance (0g taurine). The placebo will be provided in powder form, dissolved in water, and administered 30 minutes prior to exercise. This intervention serves as a control arm to evaluate the effects of taurine supplementation on exercise performance, fatigue resistance, and recovery under high-temperature and high-humidity conditions.
