摘要:
      摘要 目的:测定老年人24式简化太极拳的能量消耗范围,探讨其是否符合老年心血管患者的运动处方的要求。 方法:采用实时气体采样,不限制太极拳练习的体位,测定老年人的耗氧量(VO2)、代谢当量(METs)、心率(HR)等指标(n=200);根据膝关节弯曲角度分为高位(150°)和低位(120°)两组,再测定其上述指标。 结果:不限体位时,平均VO2为644.57±153.6ml/min,达47.90%±10.06%VO2max;平均METs为3.10±0.60,达47.74%±10.15%METsmax;平均HR为101.17±15.52bpm,达67.0%±10.25%HRmax;高位时平均VO2为541.66±96.13 ml/min,达40.85%±6.57%VO2max,低位时739.95±134.44ml/min,达54.43%±8.15%VO2max;高位时平均METs为2.63±0.31,达40.86%±7.16%METsmax,低位时3.52±0.47,达54.12%±8.18%METsmax;高位时平均HR 96.62±11.57bpm,达63.96%±7.72%HRmax,低位时105.37±17.56bpm,达69.82%±11.52%HRmax。两组间能量消耗差异有显著性(P<0.05)。 结论:简化24式太极拳运动强度、练习特点符合老年心血管患者运动处方的要求,是可调节的低-中强度的有氧运动。

Abstract:
      Abstract Objective:To evaluate the range of energy expenditure in the practice of 24-actions taijiquan in the elderly and to determine the qualification of exercises prescription of 24-actions taijiquan for the elderly with cardiovascular diseases. Method: The oxygen consumption(VO2),metabolic equivalent(MET),heart rhythm(HR) of 200 elderly patients were measured by real-time air sampling during the practice of taijiquan with or without posture limited. Result: ①Without posture limited,the mean VO2 was 644.57±153.6ml/min, reached 47.90%±10.06%VO2max; the mean METs was 3.10±0.60, reached 47.74%±10.15%METsmax; the mean HR was 101.17±15.52bpm,reached 67.0%±10.25%HRmax.②With posture limited when the knee-joint curvature was 150° or 120°, the mean VO2 was 541.66±96.13 ,739.95±134.44ml/min respectively,reached 40.85%±6.57%,54.43%±8.15%VO2max respectively; The mean METs was 2.63±0.31,3.52±0.47 respectively, reached 40.86%±7.16%,54.12%±8.18%METsmax respectively; the mean HR was 96.62±11.57,105.37±17.56 bpm respectively,reached 63.96%±7.72%,69.82%±11.52%HRmax respectively. The energy expenditure between two groups had significant difference(P<0.05). Conclusion: The intensity and practice features of 24-actions taijiquan was qualified for the exercises prescription of the elderly with cardiovascular diseases and was an adjustable aerobic exercise with mild to middle intensity.
