OBJECTIVES
Frequency-domain analysis of heart rate variability (HRV) is an effective tool to evaluate autonomic balance. This study aimed to investigate gender differences in HRV among individuals undergoing regular resistance training.
METHODS
This preliminary cross-sectional study was conducted from April to September 2016 in João Pessoa, Paraíba, Brazil. The low-frequency (LF), high-frequency (HF) and LF/HF ratio components of HRV spectral analysis were analysed among 22 men and 27 women undergoing regular resistance training.
RESULTS
Among the male participants, the LF component was significantly increased compared to females in both the supine (1,171 ± 192 versus 545 ± 74 ms; = 0.0067) and upright (1,824 ± 260 versus 738 ± 133; = 0.0011) positions. The LF/HF ratio was also significantly increased in both positions among male participants ( <0.0500 each).
CONCLUSION
These preliminary data suggest a possible gender difference in the HRV of individuals undergoing resistance training.
目的
心率变异性（HRV）的频域分析是评估自主神经平衡的有效工具。本研究旨在调查接受常规抗阻训练的个体中HRV的性别差异。
方法
这项初步横断面研究于2016年4月至9月在巴西帕拉伊巴州若昂佩索阿进行。对22名男性和27名接受常规抗阻训练的女性进行HRV频谱分析的低频（LF）、高频（HF）和LF/HF比值成分分析。
结果
在男性参与者中，仰卧位（1171±192对545±74毫秒；P = 0.0067）和直立位（1824±260对738±133；P = 0.0011）时，LF成分均显著高于女性。男性参与者在两个体位的LF/HF比值也显著升高（各P<0.0500）。
结论
这些初步数据表明，接受抗阻训练的个体在HRV方面可能存在性别差异。
