Exercise with flexible poles provides fast eccentric and concentric muscle contractions. Although the literature reports significant muscle chain activity during this exercise, it is not clear if a single bout of exercise induces cardiac changes. In this study we assessed the acute effects of flexible pole exercise on cardiac autonomic regulation.
The study was performed on 22 women between 18 and 26 years old. We assessed heart rate variability (HRV) in the time (SDNN, RMSSD and pNN50) and frequency (HF, LF and LF/HF ratio) domains and geometric indices of HRV (RRTri, TINN, SD1, SD2 and SD1/SD2 ratio). The subjects remained at rest for 10 min and then performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 60 min and HRV was analyzed.
We observed no significant changes in time domain (SDNN: p=0.72; RMSSD: p=0.94 and pNN50: p=0.92) or frequency domain indices (LF [nu]: p=0.98; LF [ms(2)]: p=0.72; HF [nu]: p=0.98; HF [ms(2)]: p=0.82 and LF/HF ratio: p=0.7) or in geometric indices (RRTri: p=0.54; TINN: p=0.77; SD1: p=0.94; SD2: p=0.67 and SD/SD2: p=0.42) before and after a single bout of flexible pole exercise.
A single bout of flexible pole exercise did not induce significant changes in cardiac autonomic regulation in healthy women.
使用柔性杆进行的锻炼可提供快速的离心和向心肌肉收缩。尽管文献报道在此类锻炼过程中存在显著的肌肉链活动,但尚不清楚单次锻炼是否会引起心脏变化。在本研究中,我们评估了柔性杆锻炼对心脏自主神经调节的急性影响。
该研究针对22名年龄在18至26岁之间的女性进行。我们在时域(SDNN、RMSSD和pNN50)和频域(HF、LF和LF/HF比值)评估了心率变异性(HRV)以及HRV的几何指数(RRTri、TINN、SD1、SD2和SD1/SD2比值)。受试者静息10分钟,然后使用柔性杆进行锻炼。锻炼方案结束后,志愿者立即静坐在原处60分钟,并对HRV进行分析。
我们观察到,单次柔性杆锻炼前后,时域指标(SDNN:p = 0.72;RMSSD:p = 0.94;pNN50:p = 0.92)、频域指标(LF[nu]:p = 0.98;LF[ms²]:p = 0.72;HF[nu]:p = 0.98;HF[ms²]:p = 0.82;LF/HF比值:p = 0.7)或几何指数(RRTri:p = 0.54;TINN:p = 0.77;SD1:p = 0.94;SD2:p = 0.67;SD1/SD2:p = 0.42)均无显著变化。
单次柔性杆锻炼未在健康女性中引起心脏自主神经调节的显著变化。
