Creatine Supplementation At Simulated Altitude

California Polytechnic State University-San Luis Obispo60 enrolled

Overview

Creatine supplementation has been shown to increase exercise performance at sea level. The goal of this study is to determine the effects of creatine supplementation on exercise performance at simulated altitude.

Military personnel often encounter harsh environments such as high altitudes and hypoxic conditions, leading to significant constraints on their exercise capacity and performance. At sea-level creatine supplementation increases exercise performance; however no experimental studies have examined the effect of creatine supplementation at simulated altitude. The overall objective of this study is to investigate the effects of creatine supplementation on exercise performance, via a repeated sprints test (Wingate Test) after a 2-day supplementation period, compared to a placebo group.
