Body composition could influence exercise physiology. However, no one has ever studied the effect of visceral fat (VF) on heart rate (HR) trends during and after exercise by using bioimpedance analysis (BIA). This study aims to investigate BIA variables as predictors of HR trends during vigorous exercise. Ninety-six participants (age 22.5 ± 4.8 years) were included in the data analysis. After performing BIA, the HR was recorded at three time points: baseline HR (BHR), peak HR (PHR) at the end of vigorous exercise, and resting HR (RHR) 1 min after the end of the exercise. After BHR, a 30 s squat jump test was performed. Linear regression analysis showed the body fat percentage and VF as a predictor of HR recovery post-exercise ( < 0.01). However, body weight has no association with HR recovery ( > 0.05). On the other hand, BIA variables were not associated with the variation of HR from the baseline to the end of the exercise. The results show that higher VF is associated with a slower HR recovery. To schedule a training program, it would be safer to monitor visceral fat before prescribing recovery time.
身体成分可能会影响运动生理学。然而,从未有人通过生物电阻抗分析(BIA)研究过内脏脂肪(VF)对运动期间及运动后心率(HR)变化趋势的影响。本研究旨在调查BIA变量作为剧烈运动期间心率变化趋势预测指标的情况。96名参与者(年龄22.5±4.8岁)纳入数据分析。进行BIA后,在三个时间点记录心率:静息心率(BHR)、剧烈运动结束时的峰值心率(PHR)以及运动结束后1分钟的静息心率(RHR)。记录BHR后,进行30秒深蹲跳测试。线性回归分析显示,体脂百分比和VF可作为运动后心率恢复的预测指标(<0.01)。然而,体重与心率恢复无关(>0.05)。另一方面,BIA变量与运动开始至结束时心率的变化无关。结果表明,较高的VF与较慢的心率恢复相关。为制定训练计划,在规定恢复时间之前监测内脏脂肪会更安全。
