Exercise responses
Treadmill running was performed at an average speed of 11.6 ± 1.4 km/h which elicited a mean heart rate of 169 ± 14 beats/min and a mean oxygen consumption of 3.08 ± 0.39 L/min equivalent to 68% ± 3% of peak oxygen uptake. The non‐protein respiratory exchange ratio was 0.93 ± 0.03, which corresponded to a proportional energy contribution of 80% ± 10% carbohydrate and 20% ± 10% fat (assuming zero contribution from protein). The estimated net oxidation of carbohydrate and fat were 174 ± 35 g and 19 ± 9 g, respectively, with an estimated net energy expenditure of 3.62 ± 0.53 MJ.
