Abstract

The present study examined the effects of different temperatures of protein-containing drink after exercise on subsequent gastric motility and energy intake in healthy young men. Twelve healthy young men completed three, one-day trials in a random order. In all trials, the subjects ran on a treadmill for 30 min at 80% of maximum heart rate. In exercise + cold drink (2 °C) and exercise + hot drink (60 °C) trials, the subjects consumed 300 mL of protein-containing drink (0.34 MJ) at 2 °C or 60 °C over a 5-min period after exercise. In the exercise (i.e., no preload) trial, the subjects sat on a chair for 5 min after exercise. Then, the subjects sat on a chair for 30 min to measure their gastric motility with an ultrasound imaging system in all trials. Thereafter, the subjects consumed a test meal until they felt comfortably full. Energy intake in the exercise + hot drink trial was 14 % and 15 % higher than the exercise (P=0.046, 95% CI: 4.010-482.538) trial and exercise + cold drink (P=0.001, 95% CI: 160.089-517.111) trial, respectively. The frequency of the gastric contractions in the exercise + hot drink trial was higher than the exercise (P=0.023) trial and exercise + cold drink (P=0.007) trial. The total frequency of gastric contractions was positively related to energy intake (r=0.386, P=0.022). These findings demonstrate that consuming protein-containing drink after exercise at 60 °C increases energy intake and that this increase may be related to the modulation of the gastric motility.
