Purpose: Examine the effect of exercise intensity of prolonged running exercise on whole-body protein metabolism and protein requirements during recovery. Methods: Seven male endurance athletes completed two randomized exercise trials (20-km run) at LOW (~55% V̇O2peak), or HIGH (~72% V̇O2peak), intensity. Participants consumed 0.6g·kg-1 CHO pre-exercise. During the 8 h post-exercise, participants consumed 8.6g·kg-1·d-1 CHO and hourly meals providing 0.93g ·kg-1·d-1 protein, enriched with indicator AA [13C] phenylalanine. Breath and urine samples were collected to determine whole-body phenylalanine flux (PheRa), oxidation (PheOx), protein synthesis (PS), breakdown (PB) and net balance (NB). Results: The rate of CHO oxidation during exercise was 60% greater in HIGH vs LOW (P<0.001). PheOx had a large effect size and tended to be greater in HIGH (d=0.844, P=0.094). NB had a large effect size and tended to be less positive in HIGH (d=0.844, P=0.094). There was a moderate effect size for PheRa PS and PB. Conclusion: Post-exercise protein requirements are elevated following high vs low intensity endurance exercise.
