Twenty middle aged endurance runners underwent physiological testing to determine their maximal oxygen uptake (VO2max), lactate threshold, ventilatory threshold, the slope variation point (SVP) of the linear relationship between running speed (RS) and heart rate (HR) both on the treadmill and during a field test, and the onset of blood lactate accumulation point. The RS, HR, VO2 and blood lactate concentration at which the different thresholds occurred were highly correlated (0.70 < r < 0.95; p < 0.01). The various indices of aerobic-anaerobic transition in the master athletes examined were shown to occur at a comparable percentage of their VO2max as compared to their younger counterparts. The tests developed for, and commonly used in adult athletes, are equally valid in this age group.
二十名中年耐力跑者接受了生理测试，以确定他们的最大摄氧量（VO2max）、乳酸阈、通气阈、跑步机测试和实地测试中跑步速度（RS）与心率（HR）线性关系的斜率变化点（SVP）以及血乳酸积累起始点。不同阈值出现时的RS、HR、VO2和血乳酸浓度高度相关（0.70 < r < 0.95；p < 0.01）。与年轻运动员相比，所研究的成年运动员有氧-无氧转换的各项指标在其VO2max的相当百分比时出现。为成年运动员开发并常用的测试在该年龄组同样有效。
