Exercise intensity during training and competition was assessed in women runners in relation to two metabolic markers determined in the laboratory, ventilatory threshold (VT) and 4 mM of blood lactic acid (OBLA). Heart rates (HRs) were then obtained during 6 days of training and during an 8 km race. These HRs were used as references for quantifying the amount of hard (> HR-OBLA), moderate (< HR-OBLA, > HR-VT) and easy (< HR-VT) intensity training. Mean maximal heart rate (HRmax) was 183 bpm, HR-OBLA was 94.8% of HRmax, and HR-VT was 82.2% of HRmax. Average weekly training time was 301.2 min, of which 45.8% was in the easy intensity range, 45.7% in the moderate intensity range, and 8.9% in the hard intensity range. Self-reports of how training time was spent differed from actual training as revealed by the monitored heart rates. Subjects reported that they completed 3 sessions per week of easy intensity training, less than 1 session of moderate intensity training, and 1.5 sessions of hard intensity training. More than 70% of the 8 km race was performed at an intensity higher than HR-OBLA (173 bpm). Although 8 km race intensity closely corresponded with that at OBLA, very little training time was spent at that running intensity. HR monitoring of training intensity provided more accurate information than self-reports of training intensity.
针对女性跑步者，结合在实验室测定的两个代谢指标——通气阈值（VT）和4毫摩尔血液乳酸（OBLA），对训练和比赛期间的运动强度进行了评估。然后在6天的训练期间和一场8公里比赛中获取心率（HR）。这些心率被用作参考，以量化高强度（>HR - OBLA）、中等强度（<HR - OBLA，>HR - VT）和低强度（<HR - VT）训练的量。平均最大心率（HRmax）为183次/分钟，HR - OBLA为HRmax的94.8%，HR - VT为HRmax的82.2%。平均每周训练时间为301.2分钟，其中45.8%处于低强度范围，45.7%处于中等强度范围，8.9%处于高强度范围。监测到的心率显示，关于训练时间分配的自我报告与实际训练情况存在差异。受试者报告称，他们每周完成3次低强度训练课程，少于1次中等强度训练课程，以及1.5次高强度训练课程。8公里比赛中超过70%的路程是以高于HR - OBLA（173次/分钟）的强度进行的。尽管8公里比赛强度与OBLA时的强度密切对应，但在该跑步强度下花费的训练时间很少。与训练强度的自我报告相比，心率监测提供了更准确的信息。
