摘要
目的：通过对Bruce跑台法进行改进研究，提出了更为合理全面的测定老年人最大摄氧量的力竭标准和对应公式，并通过实验进行验证。方法：25名年龄55．65岁的老年志愿者按照Bruce法的跑台负荷标准跑步，佩戴心肺功能测试仪进行跑台测试，监测受试者的心率变化，计算对应的最大摄氧量。结果：力竭终点参考心率阈值150b／min，推导的最大撮氧量最接近直接法测得的结果。结论：需考虑老年人的特点，完善该方法。标准：心率满足大于150b／min、心率增长速度在O．78至1．06b／min／s范围内；公式常量补偿：2．3677ml／kg／min。
Purpose： Aiming at the old people put forward a more reasonable and safe method to test the maximal oxygen uptake （VO2max） based on the Bruce Treadmill method. Methods： According to the Bruce method, 25 old people run with the cardiopulmonary to monitor changes of heart rate and calculate the VO2max. Result： Exhausted at the end of the reference rate threshold of 150b/min, the deduced VO2max value is closest to the cardiopulmonary instrument results. Conclusion： Considering the characteristics of the elder and improve this method. Standard： Heart rate is greater than 150b/min, the growth rate of heart rate ranges from 0.78 to 1.06b/min/s, and the constants compensation formula is 2.3677 ml/kg/min.
