Aerobic demands of the dance simulation game.

The purpose of this study was to assess the intensity and energy cost of dance simulation in relation to the American College of Sports Medicine (ACSM) recommendations on the quantity and quality of exercise for developing and maintaining cardiorespiratory fitness, and to assess its safety. Forty subjects (21 males and 19 females, age 17.5 +/- 0.7 years) had their heart rate (HR) and oxygen consumption (.VO(2)) measured during maximal treadmill exercise and during a dance simulation game at a self-selected level of difficulty. They were monitored for injuries during and after the study. The results showed a mean HR of 137 beats x min(-1) (139 beats x min(-1) for males and 136 beats x min(-1) for females) and a mean .VO(2) of 24.6 ml x kg(-1) x min(-1) (25.3 ml x kg(-1) x min(-1) for males and 23.8 ml x kg(-1) x min(-1) for females) during the dance simulation game test, with an estimated energy expenditure of 480 W (550 W for males and 410 W for females). The dance intensity only just meets the minimum ACSM guidelines, so dancer-players will need to play for extended periods to improve or maintain cardiorespiratory fitness or to lose weight. No injuries occurred during 201 hours of dance time.
