title: Evaluating physical and perceptual responses to exergames in Chinese children.
abstract: OBJECTIVE
  The primary objective of this study was to examine whether exergames could help children reach the recommendations for PA and cardiorespiratory fitness regarding exercise intensity. Differences in perceived physical exertion, EE, VO2, and HR between normal weight (NW) and overweight (OW) children participating in exergames were also examined.
  
  
  METHODS
  Twenty-one children (age: 10.45 ± 0.88) were assessed for EE, VO2 and HR during rest, in a maximal treadmill test, and while playing different exergames. Ratings of perceived exertion (RPE) (category range: 0 to 10) were also measured during exergaming. Three types of exergames were examined: running, table tennis, and dancing. These games were either performed on a Chinese game console, I-Dong, or another well-developed Western game console (Sony PlayStation 3 or Nintendo Wii).
  
  
  RESULTS
  Exergaming resulted in EE (kcal/min) from 2.05-5.14, VO2 (mL/kg/min) from 9.98-25.54, and HR (beats per minute) from 98.05-149.66. Children reported RPE ranging from 1.29 to 5.29. The Chinese exergame, I-Dong Running, was the only game in which children reached a moderate intensity and met the recommended minimum VO2reserve (50%) for cardiorespiratory fitness.
  
  
  CONCLUSIONS
  Exergames could provide alternative opportunities to enhance children's physical activity. They could be used as light-to-moderate PA, and with exergames, children can even reach the recommended intensity for developing and maintaining cardiorespiratory fitness.
