Central arterial stiffness, wave reflection, and heart rate variability following 4-week high-intensity resistance training intervention in young active women

Purpose Arterial stiffness, expedited wave reflection, and autonomic dysfunction are risk factors for cardiovascular disease, which is the leading cause of death in women in the United States. Evaluation of the effects of resistance training on these factors has been inconclusive, and even less is known about the effects of high-intensity resistance training (HIRT). This study evaluated the effects of a 4-week HIRT intervention on central arterial stiffness, wave reflection, and heart rate variability in young healthy and active women. Methods 9 women were recruited and underwent a 4-week control period followed by the intervention. Measurements were recorded pre-control, post-control/pre-intervention, and post-intervention. Results There were no significant changes to central arterial stiffness, wave reflection, or heart rate variability. There was a significant increase in resting heart rate (bpm: 62 ± 7, 66 ± 10; p = 0.003) and a significant decrease in baroreceptor sensitivity (30 ± 7, 21 ± 7; p = 0.018) pre- to post-intervention. There was a significant decrease in total peripheral resistance pre- to post-intervention (1.076 ± 0.281, 0.916 ± 0.250; p = 0.002). Squat, bench press, and deadlift increased pre- to post-intervention (kg: 62 ± 11, 71 ± 9, p = 0.000; 37 ± 7, 40 ± 7, p = 0.002; 76 ± 19, 84 ± 19, p = 0.000). Conclusion 4 weeks of HIRT can supplement a healthy lifestyle in women by increasing strength while decreasing peripheral resistance and preserving arterial pressures. Further evaluation is necessary to investigate the observed increase in resting heart rate and decrease in baroreceptor sensitivity and to determine long-term effects of this training..
