Brief Summary:
This study investigates the effects of green tea extract and ginger supplementation, both individually and in combination, on endurance performance, metabolism, thermal comfort, and muscle soreness in recreationally active young men. Participants will complete cycling tests under both normal room temperature (21-24°C) and cold (5-7°C) conditions. The study uses a randomized, double-blind, placebo-controlled, crossover design to compare the outcomes of placebo, green tea, ginger, and combined supplementation. The findings may help to identify nutritional strategies that improve exercise performance and comfort in different environmental conditions.
Detailed Description:
This randomized, double-blind, placebo-controlled, crossover trial is designed to evaluate the effects of green tea extract and ginger supplementation, both individually and in combination, on endurance performance, metabolic responses, thermal sensation, and muscle soreness in recreationally active men.
Sixteen healthy participants will complete eight experimental conditions: placebo, green tea extract (500 mg), ginger (1 g), and a combination of both, tested under normal (21-24°C) and cold (5-7°C) environments. Each condition will be separated by a washout period to avoid carryover effects.
Endurance capacity will be measured using a time-to-exhaustion cycling test at 70% of maximal oxygen uptake (VO₂max). Metabolic responses will be assessed by gas analysis to determine respiratory exchange ratio (RER). Perceptual measures will include the Borg Rating of Perceived Exertion (RPE) and a thermal sensation scale, while muscle soreness will be evaluated 24 hours post-exercise using a visual analog scale (VAS).
The study aims to determine whether the combined intake of green tea and ginger provides synergistic benefits over individual supplementation, particularly in cold environments where thermoregulation and endurance capacity are challenged. Findings may contribute to practical nutritional strategies that enhance exercise performance, comfort, and recovery under environmental stress conditions.
