Article Synopsis
- The study compared heart rate dynamics and variability before and after high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) using treadmill workouts.
- HIIT-4:3 showed a faster heart rate peak and greater sympathetic activity post-exercise, while HIIT-30:30 and MICT had improved heart rate variability during recovery.
- Overall, HIIT-4:3 leads to more sympathetic dominance and potential cardiac overload, whereas HIIT-30:30 enhances heart rate recovery and autonomic balance.
To test whether women with metabolic syndrome (MS) have impairments in the on- and off-transients during an incremental test and to study whether any of the MS components are independently associated with the observed responses. Thirty-six women aged 35-55 years were divided into a group with MS (MSG, = 19) and a control group (CG, = 17). R-R intervals (RRi) and heart rate variability (HRV) were calculated on a beat-to-beat basis and the heart rate (HR) at the on- and off-transient were analyzed during an incremental cardiopulmonary exercise test (CPET).
