Self-paced hard work comparing men and women.

摘要: Six fit male subjects (23 years, 171 cm, 67 kg, maximal V˚O2 = 2.25mmol kg−1 min−1 (50.3ml kg−1min−1)) and six female (22 163 cm, 57 kg, V˚O2= l.83mmol min−1(41.1 mlkg−1 min−1)) performed self-paced hard work while walking over four different terrains carrying no external load, 10 kg 20 kg. Time on each course for individual was used to determine speed energy expenditure; heart rate recorded as subject completed course. Walking expenditure of the males were found be significantly greater (p 0.05) remarkably constant at a value close 45% V˚O2max, These data indicate that voluntary is dependent upon aerobic power. The best pred...
