Gender Differences in Heart Rate Variability Among Individuals Undergoing Regular Resistance Training Preliminary observations
Journal Title: Sultan Qaboos University Medical Journal - Year 2017, Vol 17, Issue 2
Abstract
Objectives: Frequency-domain analysis of heart rate variability (HRV) is an effective tool to evaluate autonomic balance. Tis study aimed to investigate gender differences in HRV among individuals undergoing regular resistance training. Methods: Tis preliminary cross-sectional study was conducted from April to September 2016 in João Pessoa, ParaÃba, Brazil. Te 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 signifcantly increased compared to females in both the supine (1,171 ± 192 versus 545 ± 74 ms2; P = 0.0067) and upright (1,824 ± 260 versus 738 ± 133; P = 0.0011) positions. Te LF/HF ratio was also signifcantly increased in both positions among male participants (P <0.0500 each). Conclusion: Tese preliminary data suggest a possible gender difference in the HRV of individuals undergoing resistance training.
