Abstract

Research Aim:The purpose of this study was to investigate the effect of eight weeks of resistance training on heart rate variability in sedentary male students of Mohaghegh Ardabili University. Research method:30 statistical samples were divided into experimental (n= 15) and control (n= 15) groups according to the inclusion criteria. The resistance training program consisted of 3 sets of 8 to 10 repetitions with 60-70% 1RM and 2-minute rests at 3 sessions per week (one day in between). The normality of the data distribution was evaluated using Shapiro-Wilk tests. Data were analyzed using covariance analysis (ANCOVA) and intra-group data were analyzed by t-test. Statistical operations and analyzes were performed at the P<0.05 level with using SPSS 23 and Excel 2013 statistical software. Findings: The results showed that eight weeks of resistance training did not have significant effect on SDNN, LF, HF, rMSSD and LF / HF parameters. Conclusion:In general, in the present study, the performance of eight of seven resistance exercises in passively healthy men did not cause significant changes in time-centered and frequency-based indices of heart rate variability. The reason for these minor nonsignificant effects, based on the research literature, can be attributed to the healthyness of the subjects and the intensity of exercise presented in this study.
