本研究的目的是评估一组10名休闲跑步者（8男2女）在半程马拉松比赛中的生理需求。该组的平均跑步速度为223.1 +/- 22.7 m.min-1（平均+/- SD），这代表这些跑步者的最大摄氧量为79 +/- 5%。最大摄氧量与比赛表现时间之间有很好的相关性（4 = -0.81;p < 0.01），相当于血液乳酸浓度为4 mmol时的跑步速度之间的相关性甚至更好。L-1和性能次数（r = -0.877; p < 0.01）。比赛结束时4名选手血乳酸浓度为5.65±1.42 mmol。l-1（平均+/- SD），该组的估计能量消耗为6.22 M.J.，而总能量消耗与比赛表现时间之间只有较差的相关性，当每个人的能量消耗以KJ表示时，相关系数得到提高。Kg-1 min-1 （r = 0.938; p < 0.01）。
The purpose of this study was to assess the physiological demands of a half-marathon race on a group of ten recreational runners (8 men and 2 women). The average running speed was 223.1 +/- 22.7 m.min-1 (mean +/- SD) for the group and this represented 79 +/- 5% VO2 max for these runners. There was a good correlation between VO2 max and performance time for the race (4 = -0.81; p less than 0.01) and an even better correlation between running speed equivalent to a blood lactate concentration of 4 mmol.l-1 and performance times (r = -0.877; p less than 0.01). The blood lactate concentration os 4 of the runners at the end of the race was 5.65 +/- 1.42 mmol.l-1 (mean +/- SD) and the estimated energy expenditure for the group was 6.22 M.J. While there was only a poor correlation between total energy expenditure and performance time for the race, the correlation coefficient was improved when the energy expenditure of each individual was expressed in KJ.kg-1 min-1 (r = 0.938; p less than 0.01).
