Physically inactive adults are prevalent worldwide. This study compared the effects of short-term high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) on heart rate variability (HRV) in physically inactive adults as a preliminary study. Thirteen physically inactive male adults (27.5 ± 3.80 years) were randomly assigned to HIIT (N = 7) or MICT (N = 6). The HIIT program consisted of 20 min of interval training with cycling to rest ratio of 10/50 s at ≥90% HRpeak, while the MICT program consisted of 40 min of continuous cycling at 60–75% HRpeak. Both groups completed eight sessions of training within two weeks. Time and frequency domains of HRV were measured for 20 min with Actiwave-Cardio monitor (CamNtech, UK). The number of R-R interval and inter-beat interval (IBI) were significantly improved (p < 0.05) in both HIIT and MICT programs following eight sessions of training. A significant interaction effect for group by time was found in the lnLF/HF ratio (p < 0.05) where it was only improved in the HIIT group from pre- to post-test. The HIIT program is superior to MICT in improving HRV in physically inactive adults. The HIIT program can be applied as a time-efficient program for improving cardiac-autoregulation.

Introduction: High intensity interval exercise (HIIE) is performed widely. However, the field possesses limited knowledge regarding the acute HIIE cerebrovascular response. Our objective was to characterize the middle cerebral artery blood velocity (MCAv) response during an acute bout of short interval HIIE in healthy adults. We hypothesized MCAv would decrease below BL 1) during HIIE, 2) following HIIE, 3) and 30-minutes after HIIE. As a secondary objective, we investigated sex differences in the MCAv response during HIIE. Methods: Fourteen healthy adults (7 male) completed the HIIE session. The 10-minute HIIE session included alternating 1-minute bouts of high-intensity and low-intensity intervals. MCAv, mean arterial pressure (MAP), heart rate (HR), and expired end tidal carbon dioxide (PETCO2), were recorded at BL, during HIIE, following HIIE, and 30-minutes after HIIE. Results: Contrary to our hypothesis, MCAv remained above BL for the HIIE duration. MCAv peaked at the third minute then decreased concomitantly with PETCO2. MCAv was lower than BL after HIIE (p=0.03). Thirty minutes after HIIE, MCAv returned to near BL values (p = 0.47). Women showed higher BL MCAv (x = 70.9 ± 8.1 cm/s) compared to men (x = 59.3 ± 5.8 cm/s, p = 0.01). A greater magnitude of MCAv response was observed in men resulting in non-significant differences during HIIE secondary to higher workload (p = 0.03). Conclusions: Collectively, these findings show that in healthy adults, MCAv remained above BL during a 10-minute short-interval HIIE and returned to resting values 30 minutes after exercise.

High Intensity Interval

Exercise appears to have overall benefit in pulmonary arterial hypertension (PAH); however, studies to date indicate little effect on the elevated pulmonary pressure or RV hypertrophy (RVH) and dysfunction associated with the disease. High intensity interval training (HIIT) is reported to be superior to the more customary prolonged continuous exercise training (CExT) protocol for chronic heart failure but has not been tested for PAH. Therefore, we investigated impact of a 6 wk HIIT vs. CExT treadmill program in a monocrotaline rat model of mild PAH (MCT, 40 mg/kg) on indicators of disease progression. Methods: Treadmill training was performed 5x/wk in male Sprague-Dawley MCT rats (250-300g), following a protocol of either HIIT (5 cycles of 2 min at ~90% VO 2 reserve [VO 2 R] + 3 min at 30% VO 2 R; n=8), or low intensity CExT (60 min at 50% VO 2 R; n=7). Statistical analysis was performed by one-way ANOVA. Results: MCT-induced decrements in VO 2 max were ameliorated by both HIIT and CExT (p < 0.01 vs. sedentary MCT rats, MCT-SED, n=6), and were similar to healthy controls (CON, n=6). Most importantly, RV systolic pressure (RVSP, in mmHg; via Millar catheter) and RVH (ratio of RV to LV+S mass) were lowered (p<0.05) only by HIIT (28.7±2, and 0.32±0.02) and not by CExT (44.1±3, and 0.43±0.01) vs. MCT-SED (40.2±3.2, and 0.41±0.02). Cardiac output (Δ from baseline in μl, via RV echocardiography) was also improved by HIIT (117±28) vs. MCT-SED (6±42, p=0.04). Additional hemodynamic recordings during running, via novel implantable telemetry (DSI), were obtained serially at pre- and 2, 4, 6, and 8 wks post-MCT, and revealed ‘surges’ in RVSP during HIIT, vs. a steady RVSP pattern during CExT. Pulmonary eNOS (per immunoblotting) was increased (p<0.05) with HIIT, consistent with greater endothelial stimulation. Conclusions: HIIT is superior to CExT for improving hemodynamics and RV remodeling and dysfunction in MCT rats and warrants further investigation in other models and in patients. More favorable outcomes may be explained by greater sheer-stress mediated vascular endothelial adaptation to HIIT stimulus, or lower cumulative training-induced RV wall stress with the briefer HIIT session duration.
