Battling rope (BTR) exercise has become incredibly popular among not only fitness enthusiasts and athletes but in the general exercising population. Despite its popularity, research regarding the acute cardiovascular responses to BTR exercise is limited. This investigation evaluated the effects of acute BTR exercise on heart rate variability (HRV) and blood pressure (BP) responses in young men with elevated BP.
Eleven young men with elevated BP completed either a BTR or a non-exercise control trial in randomized order. The BTR trial consisted of 10 rounds of BTR exercise. Each round included 30 s of exercise followed by 30 s of rest. HRV and BP were evaluated at baseline and 3, 10, and 30 min following each trial.
There were significant elevations (p ˂0.01) in heart rate, markers of sympathetic activity (nLF), and sympathovagal balance (LnLF/LnHF, nLF/nHF) for 30 min following the BTR trial, whereas no changes from baseline were detected after control. Additionally, there were significant reductions (p ˂0.01) in markers of vagal tone (RMSSD, LnHF and nHF) and LnLF (both sympathetic and vagal modulations) for 30 min; as well as (p ˂0.01) systolic BP and diastolic BP at 10 and 30 min after the BTR, but not the control trial.
Current findings revealed that BTR exercise elevates sympathovagal balance for 30 min post-intervention, which is concurrent with an impressive hypotensive effect. Further investigations are warranted to assess the potential clinical application of BTR exercise not only in cohorts needing BP control but also in populations with limited locomotion that might benefit from post-exercise hypotension.
战绳(BTR)训练不仅在健身爱好者和运动员中,而且在普通运动人群中都变得极其流行。尽管它很受欢迎,但关于BTR训练对心血管急性反应的研究却很有限。本研究评估了急性BTR训练对血压升高的年轻男性心率变异性(HRV)和血压(BP)反应的影响。
11名血压升高的年轻男性按随机顺序完成了BTR训练或非运动对照试验。BTR训练包括10轮BTR练习。每轮包括30秒的运动,然后是30秒的休息。在每次试验的基线以及试验后3、10和30分钟评估HRV和BP。
BTR训练后30分钟,心率、交感神经活动标志物和交感迷走神经平衡(LnLF/LnHF,nLF/nHF)显著升高(p<0.01),而对照后未检测到与基线有变化。此外,迷走神经张力标志物(RMSSD、LnHF和nHF)和LnLF(交感和迷走神经调制)在30分钟内显著降低(p<0.01);以及BTR训练后10分钟和30分钟时收缩压和舒张压显著降低(p<0.01),但对照试验未出现此情况。
目前的研究结果表明,BTR训练在干预后30分钟内会提高交感迷走神经平衡,同时伴有显著的降压效果。有必要进一步研究,以评估BTR训练不仅在需要控制血压的人群中,而且在可能从运动后低血压中受益的行动受限人群中的潜在临床应用。
