摘要
目的探讨时尚健身运动对心血管自主神经调节及体质的影响,结合时尚健身运动训练过程心率的变化、HRV结果,分析时尚健身的项目特点及其独特的健身价值,为科学健身提供理论和实践依据。方法以普通女大学生为研究对象。选取身体素质条件相当的女大学生30人。随机分为实验组和对照组,各15名。实验组进行十周,一周三次时尚健身练习。实验前后采集两组受试者10周后时尚健身静息和深呼吸的心电信号和体质测试数据。通过HRV配套软件分析心电信号。使用SPSS 13.0软件对数据进行T检验、非参数检验和单因素方差分析。结果(1)受试者交感神经活性增强,LF/HF明显高于安静休息状态;时尚健身练习改变明显影响HRV的RMSSD、pNN50、HF、LF和LF/HF指标。(2)10周训练对受试者的心血管自主神经调节有些许影响,其它状态下有明显改变。(3)10周训练明显减少体重、提高柔韧和力量素质,对平衡能力和体脂也有积极影响,心肺功能有明显改变。
Objective To investigate the effect of fashionable exercise on the cardiovascular autonomic regulation and constitution and analyze the characteristics of fashionable exercise and its unique value according to the change in heart rate and heart rate variability （HRV） during fashionable exercise, and to provide a theoretical and practical basis for scientific exercise. Methods Thirty female college students with similar physical conditions were included in the study. They were randomly divided into experimental group （n = 15） and control group （n = 15）. The experimental group underwent fashionable exercise three times a week for 10 weeks. Electrocardiogram （ECG） signals and body constitution measurement data of both groups were collected during rest and deep breath before and after experiment. The ECG signals were analyzed using HRV analysis software. The data were subjected to t-test, non- parametric test, and one-way analysis of variance using SPSS 13.0. Results The subjects had increased sympathetic nerve activity, and the LF/HF was significantly higher during deep breath than during rest; fashionable exercise had a significant impact on HRV indices including RMSSD, pNN50, HF, LF, and LF/HF. The 10-week exercise had some effect on the cardiovascular autonomic regulation in subjects, and it showed significant changes under other conditions. In addition, the 10-week exercise significantly decreased body weight, increased body flexibility and strength, and improved cardiopulmonary function and had a positive impact on balance ability and body fat.
