Conclusion of this study

Body mass increased (p less than or equal to 0.05) only for the BA group at weeks 4 and 8, whereas %fat decreased (p less than or equal to 0.05) and FFM increased (p less than or equal to 0.05) at weeks 4 and 8 for all groups (BA, PL, and CON). Although it is unclear why beta-alanine supplementation increased BM, there was no additive effects for increasing VO2 peak beyond the PL. Overall, these results suggested that HIIT may be an effective and time-efficient method of training to improve maximal oxygen uptake.
