NIACIN-BOUND CHROMIUM IMPROVED CYCLING SPRINT POWER
Frank, L. L., & Baer, J. T. (2002). The effect of a chromium-containing beverage on sprint cycling performance after a submaximal exercise bout. Medicine and Science in Sports and Exercise, 34(5), Supplement abstract 14.
The effects of a 7% carbohydrate-electrolyte beverage with or without added niacin-bound trivalent chromium on sprint capacity (Wingate Anaerobic Power Test), after 60 minutes of submaximal (75% VO2max) cycling, were assessed. Ss were trained male cyclists (N = 6).
Total power in the Wingate Test was significantly greater and post-sprint lactate level was lower under the chromium-added condition. There were no differences between either condition for blood glucose, VO2, VCO2, or RER.
Implication. Niacin-bound chromium improved power output in sprint cycling.
