Values are means ± SEMs. n = 12 per group. Data were analyzed using a 1-factor ANOVA. bpm, beats per minute; O2 peak, peak oxygen consumption; Wmax, maximal workload capacity; 0 g PRO, 45 g carbohydrate with 0 g protein; 15 g PRO, 45 g carbohydrate co-ingested with 15 g milk protein; 30 g PRO, 45 g carbohydrate co-ingested with 30 g milk protein; 45 g PRO, 45 g carbohydrate co-ingested with 45 g milk protein.
