Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is designed to evaluate the effects of taurine supplementation on exercise performance under extreme environmental conditions of high temperature and high humidity. The primary goal is to investigate whether taurine supplementation can enhance performance during exhaustive exercise and subsequent repetitive sprints (RS). Sixteen college students (8 male, 8 female) will participate in a single-blind, randomized, crossover-controlled trial. Participants will be divided into four groups receiving either high-dose (6g), medium-dose (4g), low-dose (1g) taurine supplementation, or placebo.

The study will involve a protocol with exhaustive exercise followed by six repetitive sprints. Performance metrics such as peak power (PP), mean power (MP), and fatigue index (FI) will be recorded. Additionally, physiological parameters, including heart rate (HR) and blood lactate (BLA), as well as subjective measures like ratings of perceived exertion (RPE), will be monitored. A standardized measurement protocol will be used to ensure consistency and accuracy across trials.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

This study utilized a single-blind, randomized, crossover-controlled design to evaluate the effects of taurine supplementation at varying doses (6g, 4g, 1g) and placebo on exercise performance under high-temperature and high-humidity conditions. Each participant received all four interventions (high-dose, medium-dose, low-dose, and placebo) in randomized order, with a washout period between treatments to minimize carryover effects. This design allows each participant to serve as their own control, enhancing the precision of the comparisons across conditions.

Primary Study Purpose

BASIC_SCIENCE

Blinding Strategy

SINGLE

Participants

The study employed a single-blind design where participants were masked to the intervention assignments. This means that participants were unaware of whether they received high-dose taurine (6g), medium-dose taurine (4g), low-dose taurine (1g), or placebo. The care providers and investigators were aware of the intervention assignments to ensure proper administration and data collection.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High-Dose Taurine Group (6g)

Participants in this arm will receive taurine supplementation at a high dose of 6g, dissolved in water, administered 30 minutes prior to exercise.
