“…Values of these temporal domain variables were higher at the pre moment (M1), which reflects a parasympathetic activity closer to a basal state, a fact that contradicts the HR means results. In other research with psychology students, it was found that the HRV parameters sensitive to identify the autonomic modulation were PNN50, RMSSD, SD1, SD2, and HF [18], and with physiotherapy students, the sensitive parameters were PNN50, RMSSD, SD1 and SD2 [19]. With athletes' sample, PNN50, RMSSD, and HF were the parameters sensitive to identify the autonomic modulation [20], and with military population the parameters were RRSD, and RR interval mean [21].…”
