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.

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.

High-intensity interval training (HIIT) is emerging as a safe and effective means to combat chronic diseases. The objective of this work was to perform a systematic review of the effect of HIIT interventions in an aging population. Three electronic databases were searched for randomized trials comparing the effect of HIIT and moderate-intensity continuous training in older adults. After a thorough screening process, 15 articles were identified as meeting the inclusion criteria. All studies expressed a comparable or superior effect of HIIT in cardiorespiratory fitness measures. No studies reported a lessened effect of HIIT in comparison with moderate-intensity continuous training. This systematic review demonstrates that HIIT is a useful exercise regimen, which can be used in older adults to increase cardiorespiratory fitness. More research is needed to determine the effects of HIIT in an aging, predominately female population.
