From: Energy expenditure in chronic stroke patients playing Wii Sports: a pilot study

  Tennis (n = 7) Boxing (n = 8) P
VO2 (ml/min) 891.6 (249.1) 980.1 (319.2) 0.345
VO2 (ml/kg/min) 11.0 (3.9) 11.9 (3.3) 0.345
VO2 (ml/FFM/min) 17.0 (5.2) 18.1 (4.4) 0.345
HR (beats/min) 96.8 (14.7) 106.1 (20.0) 0.225
VE (L/min) 25.7 (4.7) 33.2 (10.3) 0.225
RER 0.91 (0.06) 0.95 (0.07) 0.500
Energy expenditure (METs) 3.7 (0.8) 4.1 (0.7) 0.500
Perceived exertion 4.1 (1.2) 5.3 (2.7) 0.034
  1. Values are mean ± standard deviation
  2. VO2 = oxygen uptake
  3. FFM = fat free mass
  4. HR = heart rate
  5. VE = pulmonary ventilation
  6. RER = respiratory exchange rate
  7. METs = metabolic equivalents
