Table 3. Data from the maximal exercise testing.
The data are presented as the mean±standard deviation; VGG = video game group; TG = treadmill training group; VO2 = maximal aerobic capacity; HR = heart rate; double product = HR*blood pressure; The size effect was calculated using the Cohen method and classified as small = 0.21–0.49; medium = 0.50–0.79; and large = >0.80 as previously described (Cohen 1988).
