The purpose of this study was to examine the relationship between heart rate (HR) and oxygen consumption (VO2) for aerobic dance exercise. Therefore, eleven females completed 20 minutes of aerobic dance with continuous monitoring of HR and VO2. These physiological responses were analyzed with correlation/regression techniques. The results showed that for aerobic dance to produce a response in excess of 50% of VO2 max, the target HR must be approximately 80% of the age-predicted HR max or greater. In contrast, previously reported data for treadmill running shows that 50% of VO2 max is achieved at approximately 65% of age-predicted HR max in females. The maximum heart rate reserve (Karvonen) method was also found to underestimate the actual VO2 of AD. With the Karvonen method, the target heart rate must approximate 65% of maximum HR reserve in order to elicit a VO2 response which is representative of 50% of VO2 max. These data support recent research which illustrates that target heart rate prescriptions derived from treadmill testing may fail to accurately place AD participants in the recommended training zone.
本研究的目的是探讨有氧舞蹈运动中心率(HR)与耗氧量(VO2)之间的关系。因此,11名女性完成了20分钟的有氧舞蹈,同时持续监测心率和耗氧量。这些生理反应采用相关/回归技术进行分析。结果表明,对于有氧舞蹈运动,要产生超过最大摄氧量(VO2 max)50%的反应,目标心率必须约为年龄预测最大心率(HR max)的80%或更高。相比之下,先前报道的关于跑步机跑步的数据显示,女性在约为年龄预测最大心率65%时可达到最大摄氧量的50%。还发现最大心率储备(卡尔沃宁)法低估了有氧舞蹈运动的实际耗氧量。采用卡尔沃宁法时,目标心率必须约为最大心率储备的65%,才能引发代表最大摄氧量50%的耗氧量反应。这些数据支持了最近的研究,该研究表明,从跑步机测试得出的目标心率处方可能无法准确地将有氧舞蹈运动参与者置于推荐的训练区间。
