摘要
目的分析在健康青年人中应用四肢联动进行症状限制性极量运动试验的可行性,以探索心肺适能评估的适宜设备。方法于2016年9月—2017年9月社会招募108例测试者于徐州市康复医院进行运动测试,均先后使用功率自行车和四肢联动进行症状限制性极量运动试验,测量试验过程中的心肺适能评估指标,采用Borg scale自感劳累分级表评估最大运动负荷时呼吸困难和腿部疲劳的自感劳累程度,记录测试终止的原因。结果108例测试者均顺利完成测试,达到终止标准而停止测试,未发生不良事件。使用功率自行车测试时,72例(66.7%)达到症状限制性极量运动水平;使用四肢联动测试时,102例(94.4%)达到症状限制性极量运动水平。功率自行车的绝对峰值摄氧量(VO_(2peak))、相对VO_(2peak)、相对VO_(2peak)/预测摄氧量(VO_(2pred))、峰值代谢当量(MET_(peak))、峰值心率(HR_(peak))、HR_(peak)/年龄最大预计心率(APMHR)、峰值收缩压(SBP_(peak))、峰值呼吸交换率(RER_(peak))、达到VO_(2peak)的时间(time_(peak))、达到无氧阈时绝对摄氧量(绝对VO_(2AT))、达到无氧阈时相对摄氧量(相对VO_(2AT))、相对VO_(2AT)/相对VO_(2peak)均低于四肢联动,峰值负荷、呼吸困难评分、腿部疲劳评分均高于四肢联动(P<0.05)。四肢联动的相对VO_(2peak)与功率自行车的相对VO_(2peak)呈正相关(r=0.881,P<0.001);四肢联动的HR_(peak)与功率自行车的HR_(peak)呈正相关(r=0.845,P<0.001)。结论四肢联动应用于健康青年人心肺适能评估是安全、有效、可行的,测试结果更贴近真实的心肺功能。
ObjectiveTo analysis the feasibility of a symptom limited maximal incremental cardiopulmonary exercise test using limb linkage equipment in healthy youths and explore the appropriate equipment for the assessment of the potential energy of the heart and lung.MethodsBetween September 2016 and September 2017,108 healthy youths who were tested in Xuzhou Rehabilitation Hospital were recruited and successively underwent two symptom-limited maximal incremental cardiopulmonary exercise tests using two devicesa cycle ergometer and limb linkage equipment,and the cardiopulmonary function indexes were recorded.The Borg Scale was used to evaluate the perceived exertion levels of dyspnea and leg fatigue at maximal exercise load,and the reasons for test termination were recorded.ResultsAll testees successfully completed the tests and stopped at the attainment of termination standards without any adverse events;72 （66.7%） achieved symptom limited maximal exercise levels in the cycle ergometer test,and 102 testees （94.4%） did so in the limb linkage test.The absolute peak oxygen uptake （VO2peak）,relative VO2peak,relative VO2peak/predicted oxygen uptake（VO2pred）,peak metabolic equivalent,peak heart rate （HRpeak）,HRpeak/age predicted maximum heart rate,peak systolic blood pressure,peak respiratory exchange ratio,time to VO2peak,absolute oxygen uptake at anaerobic threshold,relative oxygen uptake at anaerobic threshold （relative VO2AT）,and relative VO2AT/relative VO2peak were all significantly higher in the limb linkage test than the cycle ergometer test,whereas the peak load,dyspnea score,and leg fatigue score were invariably lower in the limb linkage test than the cycle ergometer test （P〈0.05）.There was a positive correlation between the relative VO2peak （r=0.881,P〈0.001） and the HRpeak （r=0.845,P〈0.001） between both tests.ConclusionLimb linkage equipment is safer and more effective and can be feasibly used to assess cardiorespiratory fitness in young people;it provides test results closer to the real scenario.
