原始语种摘要: Abstract(#br)β -Alanine (BA) supplementation results in elevated intramuscular carnosine content, enhancing buffering capacity during intense exercise. Although men have greater muscle carnosine content than women, elevations still appear to occur despite high baseline levels. Recent research has suggested that BA supplementation may also reduce muscle l -histidine. Thus, the purpose of this investigation was to compare 28 days of BA (6 g·d −1 ) supplementation in men and women on performance and muscle carnosine, l -histidine, and BA. We hypothesized that supplementation would result in similar elevations in carnosine and performance between sexes and decrease l -histidine. Twenty-six men and women were assigned either BA or placebo (PLA). At baseline, a trend toward greater carnosine (...
