Whilst high-intensity interval training (HIIT) is a powerful stimulus to increase endurance exercise performance, there are potential nutritional interventions that can be put in place to further increase performance gains.~Energy for the contraction of muscles is created in the mitochondria. HIIT can improve the function of mitochondria, therefore improving performance.~Β-alanine is a commonly used supplement that can improve exercise performance by increasing the amount of carnosine in muscle. Carnosine has many functions that may help improve exercise capacity.~The present study will seek to quantify whether a period of HIIT alongside β-alanine supplementation will improve the adaptation to training, and therefore performance, more than a period of HIIT alone.
