Introduction: The practice of physical exercise is recommended for the prevention and rehabilitation of several aspects related to health and HRV is an excellent non-invasive method used to assess the autonomic nervous system. Objective: To verify the acute effect of passive static stretching on the heart rate variability in sedentary individuals. Materials and Methods: Fifteen sedentary men (Age 23.6 ± 3.7, body mass 77.6 ± 13.7, height 1.76 ± 0.1) participated in the study, without the presence of cardiovascular, neurological or musculoskeletal injuries. Participants were allocated group). The stretching protocol was run in 4 sets of 30 seconds for both sides. Results: There was a significant difference in the HRV, RMSSD, SDNN and HF indices for both large groupings and small muscle groups. Discussion: Due to its simplicity of execution, muscle stretching exercises are an excellent option to start a training program in sedentary or sick individuals. Conclusion: The stretching of a large and small muscle group performed with 4 sets of 30 seconds was able to demonstrate significant physiological results on HRV.
