Data were obtained from 13 sprint (age range 41-58) and 13 distance (age range 4-78) Masters track athletes. The mean VO2max value for the distance runners was 54.4 +/- 3 ml kg min compared with 47.2 +/- 2 ml kg min for the sprinters. The highest VO2max (71.0 ml kg min) was obtained on a 45-year-old distance runner while the lowest (27.3 ml kg min) was obtained on the oldest (78 years) distance runner. VO2max decreased by 34.5% from age 40 to 70 in the distance runner in spite of continued training that ranged from 40 to 120 miles/week. Maximum ventilation rates were 122.5 +/- 6.8 and 116.8 +/- 7.0 1 min for the sprint and distance runners, respectively. Percentage of body fat was 16.5 +/- 0.5 for the sprinters and 18.0 +/- 1.1 for the distance runners. Serum cholesterol values were 218.7 +/- 8.7 and 203.0 +/- 13.8 ml/dl, while triglyceride values were 101.5 +/- 8.2 and 84.1 +/- 9.3 mg/dl for the sprint and distance groups, respectively. These data indicate that, VO2max decreases significantly with aging despite the continuation of long distance training. Percent body fat and serum lipid levels were significantly lower in these athletes compared to those for sedentary adults, suggesting a protective effect against coronary heart disease. Only one subject had S-T segment depression during the exercise test.
数据来自13名短跑（年龄范围41 - 58岁）和13名长跑（年龄范围4 - 78岁）的老年田径运动员。长跑运动员的平均最大摄氧量为54.4±3毫升/千克·分钟，短跑运动员为47.2±2毫升/千克·分钟。最高的最大摄氧量（71.0毫升/千克·分钟）出现在一名45岁的长跑运动员身上，而最低的（27.3毫升/千克·分钟）出现在年龄最大（78岁）的长跑运动员身上。尽管长跑运动员持续进行每周40至120英里的训练，但从40岁到70岁，其最大摄氧量仍下降了34.5%。短跑和长跑运动员的最大通气率分别为122.5±6.8和116.8±7.0升/分钟。短跑运动员的体脂百分比为16.5±0.5，长跑运动员为18.0±1.1。短跑组和长跑组的血清胆固醇值分别为218.7±8.7和203.0±13.8毫克/分升，甘油三酯值分别为101.5±8.2和84.1±9.3毫克/分升。这些数据表明，尽管持续进行长跑训练，但最大摄氧量仍会随着年龄增长而显著下降。与久坐不动的成年人相比，这些运动员的体脂百分比和血清脂质水平显著更低，这表明对冠心病有保护作用。在运动测试中只有一名受试者出现S - T段压低。
