Short-term Creatine Supplementation Suppresses the Cortisol Response to a High-Intensity Swim-Sprint Workout

The primary aim of the present study was to evaluate the effects of creatine ingestion on the metabolic hormone cortisol in male swimmers. Seventeen male swimmers (24.5 ± 3.9 years) with at least 5 years of competitive swimming experience and engaged in swimming training at least 4 times per week participated in the study. Subjects supplemented with creatine (20 g/day) + maltodextrin (1g/kg/day) or maltodextrin (1g/kg/day) only for 6 days prior to a progressive swim-sprint workout. The swim-sprint workout consisted of 8 progressive 100 meter freestyle sets starting at 65% of maximal intensity leading up to a 100% maximum capacity set on the eighth and final set.
