SHORT-TERM CREATINE-PYRUVATE SUPPLEMENTATION DOES NOT IMPROVE CYCLING PERFORMANCE
Van Schuylenbergh, R., Van Leemputte, M., & Hespel, P. (2003). Effects of oral creatine-pyruvate supplementation in cycling performance. International Journal of Sports Medicine, 24, 144-150.
Creatine-pyruvate (2 x 3.5 gm/d) was ingested by cyclists (N = 7) while another group (N = 7) ingested a placebo. Cycling ergometer performances were evaluated for a one-hour time trial. Immediately upon completion, Ss did 5 x 10s sprints with 2-min rest intervals.
Peak and mean power outputs, blood lactate levels, and heart rates were similar between the groups at all times.
Implication. One week of creatine-pyruvate supplementation does not beneficially influence endurance or intermittent sprint cycling in cyclists.
