Impact of Carbohydrate-Electrolyte Beverage Ingestion on Heart Rate Response While Climbing Mountain Fuji at ~3000 m

Figure 1

Profile of the present study. Participants consumed tap water or a carbohydrate-electrolyte beverage freely throughout the two days of the study except for the first 40 min before beginning to climb up the mountain on the first day, during which time we measured their body weight and peak aerobic capacity. In addition, we measured their energy expenditure and heart rate continuously while climbing up and down the mountain. Then, after climbing down the mountain, we measured body weight again. The measurements are shown in the procedure of the text.
