Acute citrulline malate shows promise for male sprinters going for gold

Acute citrulline malate (CM) supplementation (8 g) in trained male sprinters showed a modest improvement in repeated 100 m sprint performance and reduced perceived exertion during the second sprint in a randomized, double-blind crossover study. The findings suggest potential benefits for recovery, blood lactate response, and fatigue reduction, possibly via nitric oxide and metabolic effects, though mechanisms remain uncertain.
