Energy expenditure measurement in badminton players during a training camp using doubly-labelled water

The quantity of physical activity and energy expenditure of badminton players have been studied in general using heart rate monitoring. There are many research reports concerning the physical activity of a game of badminton (Seki et al., 1982; Araragi et al., 1999; Cabello et al., 2003). In order to obtain good results in an international match, it is necessary to prepare for the target game. For that purpose, we need to understand the habitual energy consumption (in training camp, on tour, during competition games and so on) that a player expends.
