Mean (± SEM) Heart Rate (HR; bpm) following drink ingestion containing (i) flavored water (control, ~ 2 kcal) or (ii) 70 g whey protein (280 kcal; ‘P₂₈₀’); (iii) 14 g whey protein, 28 g carbohydrate, 12.4 g fat (280 kcal; ‘M₂₈₀’); (iv) 70 g protein, 28 g carbohydrate, 12.4 g fat (504 kcal; ‘M₅₀₄’) in older (n = 13) men. Drink-condition effects were determined by using repeated-measures ANOVA. Baseline Heart rate represented as BL in the figure was calculated as an average of -9, -6 and -3 min readings. HR increased after the M₅₀₄ (P < 0.001) and P₂₈₀ (P = 0.017) drinks when compared to control (0-180 min)
