HIGH-INTENSITY PERFORMANCE NOT AFFECTED BY PRE-EXERCISE CARBOHYDRATE OR TRIGLYCERIDE SUPPLEMENTATION
Khodiguian, N., Hawkins, S. A., Cornwell, A., DiCaprio, P. A., & Crespo, N. (2002). The effects of medium chain triglycerides on high intensity running performance Medicine and Science in Sports and Exercise, 34(5), Supplement abstract .1315
The effects of pre-exercise medium chain triglycerides (MCT) on high-intensity running performance were determined. Males (N = 13) exercised four times with 7-14 days between bouts. Ss performed a maximal run to exhaustion at 80% VO2max. After a baseline testing session, Ss ingested carbohydrates (CHO), MCT, or placebo before exercising.
There were no differences between conditions for exercise duration, intensity, heart rate, or respiratory exchange ratio. The two experimental conditions produced different biochemical responses.
Implication. Although pre-exercise feedings did affect biochemistry, high-intensity running performance was not affected.
