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.
