High-Intensity Intermittent Exercise and Autonomic Modulation: Effects of Different Volume Sessions

Abstract The aim of this study was to compare heart rate variability (HRV) recovery after 2 sessions of high-intensity intermittent exercise at different volumes (1.25 km [HIIE 1.25 ] and 2.5 km [HIIE 2.5 ]). 13 participants determined their maximal aerobic speed (MAS) and completed 2 HIIE (1:1 at 1...

Zusammenfassung:	Abstract The aim of this study was to compare heart rate variability (HRV) recovery after 2 sessions of high-intensity intermittent exercise at different volumes (1.25 km [HIIE 1.25 ] and 2.5 km [HIIE 2.5 ]). 13 participants determined their maximal aerobic speed (MAS) and completed 2 HIIE (1:1 at 100% MAS) trials. The heart rate was recorded before and after each session. HRV indicators were calculated according to time (RMSSD and SDNN) and frequency (LF, HF and LF/HF ratio) domains. SDNN and RMSSD presented effect of test (F=20.97; p
