Trial overview
Official title: A Study to Evaluate the Effects of Protein Supplementation in Attenuating the Decline in Performance Following Strenuous Concurrent Exercise
Trial description: This study is designed to investigate whether protein supplementation can improve recovery of muscle function following a strenuous combination of both endurance and resistance exercise. It will specifically investigate the effect of protein supplementation on the recovery of strength, power and endurance exercise performance, along with measures of damage and inflammation of the muscle.
