| This study investigated whether the basic Nintendo Wii Fit aerobic games elicit sufficient intensity for the improvement and maintenance of cardiorespiratory fitness. Cardiorespiratory and metabolic responses while playing three trials of the beginner Nintendo Wii Fit aerobic games, Basic Hula Hoop, Basic Step, and Basic Run, were measured in 20 young adults (9 men aged 23.8 +/- 3.3 years and 11 women aged 24.5 +/- 2.1 years). Intensity during the Nintendo Wii Fit aerobic game-play protocol averaged 37% of heart rate reserve (HRR), 10 for rating of perceived exertion (RPE), 3.4 metabolic equivalents (METS), and 131 kcal estimated energy expenditure over 30 min. For maintenance and improvement of cardiorespiratory fitness, the American College of Sports Medicine (ACSM) recommends a minimal exercise intensity of 40/50% HRR and an RPE of 12. To receive health benefits, ACSM recommends exercising at a minimum intensity of 3 METS and expending a daily minimum of 150 kcals per exercise session.;Out of the four metabolic variables measured, METS was the only variable that met ACSM recommendations for improving health and fitness. It was concluded that the basic Nintendo Wii Fit aerobic games may improve health and aid in weight loss, but they will not maintain or improve cardiovascular fitness in healthy, young adults. |
