TABLE 3.
One-way repeated measures analysis of variance (ANOVA) comparing skin body temperature, mean and maximum heart rate, and maximal metabolic respiratory variables between the three experimental conditions during the steady-state test.

Mean ± standard deviation. PLA, Placebo; HD, high dose; LD, low dose; FOpeak, Peak of fat oxidation; CHOOXpeak, Peak of carbohydrate oxidation; MEEpeak, Peak of energy expenditure; MRERpeak, Peak of respiratory exchange ratio. * Significant difference: p ≤ 0.05.
