Ventilatory response to carbon dioxide (deltaVE/deltaPCO2) was measured in 23 teenage swimmers chosen by their coach for their potential for future athletic success. Siblings and parents of these swimmers were also studied. We found a strong relation between siblings' de;taVE/DELTAPCO2, whether or not they were swimmers (r=0.71, P less than 0.01). A weaker relationship was found between mother's and children's deltaVE/DELTAPCO2 (r==0.39, P less than 0.01). No association was found between swimming training and deltaVE/deltaPCO2. One swimmer 12 years of age had an extremely low deltaVE/PCO2 (0.42 liter per min per mm Hg) She was the only swimmer among these 23 potential champions to achieve international success in endurance events in the 2 years after the study. We concluded that family factors are important determinants of a subject's deltaVE/PCO2 and suggest that measurement of this aspect of chemical drive to breathing in young athletes may help identify those most likely to succeed in endurance events.
对23名被教练选中、有未来运动成功潜力的青少年游泳运动员测量了对二氧化碳的通气反应（δVE/δPCO2）。还对这些游泳运动员的兄弟姐妹及父母进行了研究。我们发现兄弟姐妹的δVE/δPCO2之间存在很强的相关性，无论他们是否为游泳运动员（r = 0.71，P < 0.01）。母亲与孩子的δVE/δPCO2之间的相关性较弱（r = 0.39，P < 0.01）。未发现游泳训练与δVE/δPCO2之间存在关联。一名12岁的游泳运动员的δVE/PCO2极低（0.42升/分钟/毫米汞柱）。在研究后的两年里，她是这23名潜在冠军中唯一在耐力项目上取得国际成功的游泳运动员。我们得出结论，家庭因素是受试者δVE/PCO2的重要决定因素，并建议在年轻运动员中测量这种对呼吸的化学驱动方面，可能有助于识别那些最有可能在耐力项目中取得成功的人。
