老年迪斯科健身操(舞)比赛前后心肺机能变化的研究

Research on the changes of old people's cardio-respiratory functions before and after the competition of Disco Aerobic gymnastics (dance) in Sichuan Province

老年迪斯科健身运动目前越来越为中老年人所喜爱,它对于增进中老年人的身心健康具有良好的作用。深入研究迪斯科运动对中老年人心肺机能的影响,对于科学地指导老年人健身运动具有重要的意义。本文应用超声多普勒和肺功能仪等先进仪器,对参加1988年四川省老年迪斯科健身舞比赛的32名运动员进行了现场测试,就比赛前后的心血管、呼吸系统机能等多项指标进行了研究,所获数据用电子计算机进行统计学处理。结果表明:比赛后心脏射血加速度,射血速度、射血距离、收缩压、脉搏以及第1秒时间肺活量百分数、肺最大通气量等指标均有明显增高(P<00·1和P<0.05);舒张压及肺活量赛后无变化(P>0.05)。

Recently, Disco has become one of old people's favorite Keep-fit exercise, which processes a good effect on adults'body and psychological health. There is a important significance for directig old people's aerobic exercise upon the cardio—respiratory functions. The instant measurements were carried on 32 subjects (age: over 60 year old) in the competition of Sichuan Old people Disco Aerobic Dance in 1988 with Ultrasonic Doppler and Vitalograph. The functional indexes and parameters of cardio-respiratory systems oefore and after the Competition were studycd. The statistics procedure on the data was made by means of microcomputer. The results showed that there arc a significant increase that cardiac shooting acceleration (CSA), shooting speed (SS), shooting distance (SD), systolic blood pressure (SBP), and so forth (P<0.01 and P<0.05), while diastolic blood pressure (DBP) and vital volum did not showed a rcrnarkable changes after theCompetition (P>0.05)
