| Summary: | Purpose: This study investigated the impact of two different resistance training (RT) protocols on cardiac autonomic modulation during exercise recovery in trained individuals. It was hypothesized that a hypertrophic resistance training program would induce more significant stress and negatively affect cardiac autonomic modulation compared to a power/force resistance training program. Methods: Six healthy, trained participants (aged 18–40) were randomized in a crossover and controlled pilot study. Participants performed two RT protocols: (i) three sets of 10 repetitions with 85% of 10 RM, 60 s inter-set rest (3x10<sub>60s</sub>) and (ii) eight sets of three repetitions with 85% of 3 RM, 120 s inter-set rest (8x3<sub>120s</sub>). Heart rate variability (HRV) was measured before and 30 min after each RT session. Results: Significant reductions in HRV parameters (RMSSD, HF, and SD1) were observed following the 3x10<sub>60s</sub> protocol (hypertrophic design) compared to baseline. Conversely, the 8x3<sub>120s</sub> (power/force design) protocol did not show significant changes in HRV parameters. A significant interaction effect for time and RT protocol was found for all HRV measures with more significant reductions observed after 3x10<sub>60s</sub> compared to 8x3<sub>120s</sub>. Conclusions: The hypertrophic RT session (3x10<sub>60s</sub>) significantly reduced HRV parameters, suggesting higher physiological stress and potentially negative implications for cardiac autonomic recovery than the power/force RT session (8x3<sub>120s</sub>). These findings highlight the importance of considering exercise intensity and protocol design to manage cardiac autonomic stress during resistance training. |
