The purpose of the present study was to assess fitness and running performance in a group of recreational runners (men, n = 18; women, n = 13). 'Fitness' was determined on the basis of their physiological and metabolic responses during maximal and submaximal exercise. There were strong correlations between VO2 max and treadmill running speeds equivalent to blood lactate concentrations of 2 mmol l-1 (V-2 mM) or 4 mmol l-1 (V-4 mM), 'relative running economy' and 5 km times (r = -0.84), but modest and non-significant correlations between muscle fibre composition and running performance. The results of the submaximal exercise tests suggested that the female runners were as well trained as the male runners. However, the men still recorded faster 5 km times (19.20 +/- 1.97 min vs 20.97 +/- 1.70 min; P less than 0.05). Therefore the of the present study suggest that the faster performance times recorded by the men were best explained by their higher VO2 max values, rather than their training status per se.
本研究的目的是评估一组业余跑步者（男性，n = 18；女性，n = 13）的体能和跑步表现。“体能”是根据他们在最大强度和次最大强度运动期间的生理和代谢反应来确定的。最大摄氧量与相当于血乳酸浓度为2 mmol/L（V-2 mM）或4 mmol/L（V-4 mM）的跑步机跑步速度、“相对跑步经济性”和5公里跑时间之间存在强相关性（r = -0.84），但肌肉纤维组成与跑步表现之间的相关性较弱且无统计学意义。次最大强度运动测试的结果表明，女性跑步者与男性跑步者的训练水平相当。然而，男性的5公里跑时间仍然更快（19.20 +/- 1.97分钟对20.97 +/- 1.70分钟；P < 0.05）。因此，本研究结果表明，男性更快的跑步成绩最好用他们更高的最大摄氧量来解释，而不是他们本身的训练状态。
