中老年男性太极拳高、低架野马分鬃、倒卷肱与云手练习中的气体代谢和能量消耗特征

Gaseous Metabolism and Expenditure of Energy in the Process of TaiJiQuan's Yemafenzong,Daojuangong and Yunshou Movements Exercise of the Elderly Men

目的:探讨太极拳野马分鬃、倒卷肱和云手高、低架势动作的气体代谢和能量消耗特征,为编排太极拳动作及中老年人运动处方的制定提供参考依据。方法:运用k4b2气体分析仪采集17名中老年男性进行3分钟野马分鬃、倒卷肱和云手高、低架势(高架:膝关节角度为110°～130°;低架:膝关节角度为90°～110°)练习过程中的呼吸频率、摄氧量、相对摄氧量、心率、氧脉搏、通气量和能耗等气体代谢和能量消耗指标。结果:同一架势下,3个动作之间呼吸频率、摄氧量、相对摄氧量、心率、氧脉搏、通气量和能耗均无显著性差异(P>0.05);高、低架野马分鬃之间呼吸频率、摄氧量、相对摄氧量、心率、氧脉搏、通气量和能耗有非常显著性差异(P<0.01);高、低架云手之间摄氧量、相对摄氧量和能耗有显著性差异(P<0.05),而呼吸频率、心率、氧脉搏、通气量无显著性差异(P>0.05);高架倒卷肱除呼吸频率外,摄氧量、相对摄氧量、心率、氧脉搏、通气量和能耗均显著低于低架倒卷肱(P<0.01)。结论:相同架势练习时,野马分鬃、倒卷肱、云手运动强度相似,3个动作的运动强度有明显的架势依赖性。

Objective The gaseous metabolism and expenditure of energy of three typical movements of Taijiquan were investigated in elderly men.Methods Seventeen elderly men participated in this study.RF,HR,VO2/HR,VO2,VE,VO2/kg,EE were measured during practice of Yemafenzong,Daojuangong and Yunshou movements by using K4b2 telemetry system.The knee angle of higher posture was 110°～130° and lower posture was 90°～110°.Results There were no significant differences in RF,HR,VO2/HR,VO2,VE,VO2/kg,EE among three movements（P 0.05）.There were significant differences in RF,HR,VO2/HR,VO2,VE,VO2/kg,EE（P 0.01）in Yemafenzong between lower posture and higher posture.Except for RF,HR,VO2/HR,VE,VO2,VO2/kg,EE showed significant differences（P 0.05） in Yunshou between lower posture and higher posture.Except for RF,HR,VO2/HR,VO2,VE,VO2/kg,EE showed significant differences（P 0.01） in Daojuangong between lower posture and higher posture.Conclusion In the same posture state,exercise intensity was similar among three typical movements.The difference of exercise intensity depended on different postures.
