Bffects of Continuously Performing 24 Form Taijiquan Exercises One to Three Times on Cardiovascular Functions of Old People

针对健康的中、老年人及患有各种心脑血管慢性疾病并已处于恢复状态的老年人提出：采用24式简化太极拳作为增强体质手段时，应怎样掌握运动量和强度？为此进行了以下研究。对象是北京体育大学的离退休干部共12人，对他们进行了不同遍数24式简化太极拳练习前安静时、运动中及恢复期的心率、血压及心脏统构和功能的超声心动图测试。结果发现：1）24式简化太极拳属中、小强度的有氧运动；2）连续练习两套、三套此拳后，即刻的测试呈现练习者血压的收缩压和舒张压与未练习安静时对比，均有所下降，并且有显著性差异；3）超声心动图的实测证明接连练两套及三套后即刻对心脏泵血功能的效应优于练一套后的反应。

How to control the amount and intensity of exercise,when performing 24 form Taijiquan exercises as the means of promoting physique is a question,put forward to healthy middle－aged people,old people and persons who suffered from various chronic cardiovascular and cerebrovascular diseases and havenow recovered. For this purpose a test was taken to 12 cadres of BUPE who had retired or retired on fullpay. Blood pressure,heart rate and echocardiogram were taken at rest before doing different times of 24form Taijiquan exercises,during exercise and in the recovery period. The resu1ts indicate: 1 )24 form Taijiquan belongs to aerobic exercise of middle or small intensity. 2)After doing Taijiquan exercises two orthree times the systolic and diastolic pressures of the subjects decreased significantly,compared with thosebefore exercise. 3)Effects of cardiac pumping function,shown by their echocardiograms,immediately aftercontinuously doing Taijiquan exercises two or three times were better than those after doing them onlyonce.
