In elderly people, obesity may induce changes in the autonomic nervous system via alteration of the balance between the sympathetic and parasympathetic nervous systems. Little is known about obesity and parasympathetic reactivation following exercise testing, particularly in young people in Saudi Arabia, and its relationship with body composition parameters.
Compare parasympathetic reactivation using heart rate recovery (HRR) following the exercise test between young obese and nonobese people and explore the association between body composition parameters with HRR.
Cross-sectional study.
University research lab.
Twenty-seven young male college students underwent anthropometric measurements and treadmill exercise testing, during which the heart rate was monitored via 12-lead electro-cardiography. Participants were divided into a group (n=15) with high body fat percentage (>30%), and a group (n=12) with a normal body fat percentage (<30%) to compare multiple parameters including HRR, which was defined as the absolute change from heart rate (HR) peak during exercise to 1-minute post-HR peak.
HRR, body mass index, waist-to-hip ratio, fat percentage, and trunk fat. SAMPLE SIZE AND CHARACTERISTICS: n=27, mean (SD) age=22.4 (0.98) years, range 21-25 years.
There was no significant difference in HRR between the groups (32.20 [13.42] bpm for high body fat percentage vs 35.42 [13.35] bpm for normal body fat percentage) ( P=.54). We found a non-significant inverse correlations of HRR with BMI (r=-0.18, P=.37), WHR (r=-0.04, P=.86), fat percentage (r=-0.18, P=.38) and trunk fat (r=-0.23, P=.25).
HRR was preserved in our young obese people and was not different from nonobese people. Furthermore, it seems that obese people with higher body composition parameters may have slower HRR, or slower recovery indicating poorer parasympathetic reactivation.
Need a larger sample to confirm the findings of this pilot study.
None.
在老年人中，肥胖可能通过改变交感神经系统和副交感神经系统之间的平衡来诱发自主神经系统的变化。关于运动测试后的肥胖与副交感神经再激活，尤其是沙特阿拉伯年轻人中的情况，以及其与身体成分参数的关系，人们了解甚少。
比较年轻肥胖者和非肥胖者运动测试后使用心率恢复（HRR）的副交感神经再激活情况，并探讨身体成分参数与HRR之间的关联。
横断面研究。
大学研究实验室。
27名年轻男性大学生接受了人体测量和跑步机运动测试，期间通过12导联心电图监测心率。参与者被分为高体脂百分比组（n = 15，>30%）和正常体脂百分比组（n = 12，<30%），以比较包括HRR在内的多个参数，HRR定义为运动期间心率（HR）峰值到HR峰值后1分钟的绝对变化。
HRR、体重指数、腰臀比、脂肪百分比和躯干脂肪。样本量和特征：n = 27，平均（标准差）年龄 = 22.4（0.98）岁，范围21 - 25岁。
两组之间的HRR无显著差异（高体脂百分比组为32.20 [13.42]次/分钟，正常体脂百分比组为35.42 [13.35]次/分钟）（P = 0.54）。我们发现HRR与体重指数（r = -0.18，P = 0.37）、腰臀比（r = -0.04，P = 0.86）、脂肪百分比（r = -0.18，P = 0.38）和躯干脂肪（r = -0.23，P = 0.25）之间存在非显著的负相关。
我们的年轻肥胖者中HRR得以保留，与非肥胖者无差异。此外，似乎身体成分参数较高的肥胖者可能HRR较慢，或恢复较慢，表明副交感神经再激活较差。
需要更大的样本量来证实这项初步研究的结果。
无。
