CHROMIUM IMPROVES MAXIMAL PERFORMANCE AFTER PROLONGED EXERCISE

Horn, M. E., Baer, J. T., & Vanderburgh, P. M. (1998). Improved sprint cycle performance following consumption of a chromium-carbohydrate beverage during prolonged exercise. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 878.

Male cyclists (N = 11) performed two separate trials at 75% VO2max for 60 minutes followed by a 45-s Wingate anaerobic Power Test. Ss ingested a chromium-carbohydrate or a carbohydrate drink (3 mg/kg) in four doses during the continuous exercise trial.

Anaerobic work output was significantly greater after the chromium-CHO drink than with CHO alone.

Implication. Chromium ingestion improves maximal exercise performance after prolonged exercise. It might be a dietary substance that will add "power" to a finishing effort.
