Abstract Bodybuilder‐type workouts may affect heart rate variability (HRV), which has considerable potential to assess the role of autonomic nervous system (ANS). A scientifically designed approach is necessary for bodybuilders achieve better results while protecting their health. In this study, we aimed investigate HRV parameters in compared healthy control subjects and effects creatine supplementation. total 48 male participants (16 controls, 16 supplement (–), (+)) were evaluated our study. Bodybuilders who taking supplementation enrolled (+) group. measured from 24‐hour Holter recordings all participants. When mean rates with group (71.5 ± 12.6 beats/min), statistically significant difference was revealed (–) (61.8 6.8 beats/min; P = 0.022) unlike (69.63 14.1 0.650). analyses parasympathetic shift No demonstrated on parameters, except high frequency (P 0.029) Conclusively, elevated modulation, favorable cardiovascular outcome exercise, bodybuilders. However, study also that attenuates effect ANS by limiting elevation modulation. Although sympathetic slight attributed supplementation, it cannot be discriminated over training.
