Endurance athletes possess superior ability to sustain high ventilation. However, it remains unknown if this high ventilatory endurance is an effect of training. As one approach to this question, we compared the breathing endurance of eight distance runners with that of eight of their siblings who were untrained. In two separate tests involving seated isocapnic hyperpnea, the athletes had greater ability to sustain high VE than did their brothers and sisters. In the first test, VE was voluntarily incremented by 30 l/min each 4 min. Before exhaustion, the athletes reached a VE that was a significantly greater fraction of their 12-s maximal voluntary ventilation than did the untrained siblings (75 vs. 62%; P less than 0.01). In the second test, 80% of the 12-s MVV was sustained until exhaustion. Endurance times for the athletes doubled those of the untrained siblings (7 vs. 3 min; P less than 0.05). The failure of elevated ventilatory endurance to occur in family clusters suggests that it may primarily result from training.
耐力运动员具备维持高通气量的卓越能力。然而，这种高通气耐力是否是训练的结果仍不明确。作为探讨这个问题的一种方法，我们将八名长跑运动员的呼吸耐力与其八名未受过训练的兄弟姐妹的呼吸耐力进行了比较。在两项独立的涉及坐位等碳酸血症过度通气的测试中，运动员比他们的兄弟姐妹有更强的维持高每分钟通气量（VE）的能力。在第一次测试中，VE每4分钟自愿增加30升/分钟。在疲劳之前，运动员达到的VE占其12秒最大自主通气量的比例显著高于未受过训练的兄弟姐妹（75%对62%；P<0.01）。在第二次测试中，维持12秒最大自主通气量的80%直至疲劳。运动员的耐力时间是未受过训练的兄弟姐妹的两倍（7分钟对3分钟；P<0.05）。通气耐力在家族群体中未出现增强，这表明它可能主要是训练的结果。
