Description
Alkaline supplementation has been shown in previous research to improve the body’s ability to buffer lactic acid during maximal exercise. PURPOSE: To determine the physiological and performance effects a 7-day alkaline supplementation period has on a maximal 1,300-m cycling effort compared to a placebo group. METHODS: The study consisted of three visits: an introductory visit, a visit before supplementation and a visit the day after supplementation was completed. The second and third visits consisted of a 10-minute warmup, a 1,300-m maximal cycling effort, and a 10-minute cool down. During this visit, lactate concentration (LC), heart rate (HR), oxygen intake (VO2), carbon dioxide output (VCO2), and respiratory exchange ratio (RER) were taken periodically during the all-out effort and cool down period; time to completion was also measured. Participants would then return 7 days later and perform the same procedures after fully completing the 7-day treatment. A t-test was performed to determine if there was a significant difference in means between the placebo and supplement groups for each variable. RESULTS: No statistical differences were observed between treatment groups (p
