Group mean (± SD) baseline physical characteristics and physiological responses to the ramp incremental cycling test, bout 1 of the repeated 3-min all-out cycling test, and whole thigh muscle carnosine content for the placebo (PL) and β-alanine (BA) groups.

The post-supplementation whole thigh muscle carnosine values are presented as the mean of the two post-supplementation scans at 4 and 6 weeks. No significant differences were observed between the groups (P > 0.05).
