Effects of self-paced high-intensity interval training and moderateintensity continuous training on the physical performance and psychophysiological responses in recreationally active young adults

The aim of the study was to investigate the effects of 4-week small-sided games (SSG) and high-intensity interval training with changes of direction (HIT-COD) on physical performance and specific technical skills in female collegiate basketball players. Nineteen players were divided into SSG (n = 9) and HIT-COD (n = 10) groups, that performed either SSG or HIT-COD three times per week for 4 weeks during the pre-season. Players’ heart rate (HR) and perceived exertion responses (RPE) were assessed during the intervention. Before and after the intervention period, performances were assessed with 30-15 intermittent fitness test (30-15IFT), repeated sprint ability (RSA) test, modified agility T-test (MAT), countermovement jump (CMJ), 20-m sprint, shooting accuracy test, 1 min shooting test, passing test, defensive movement test and control dribble test. Both training interventions led to similar physiological and perceived exertion responses, showing no significant differences in HR ( P = .49, d = 0.2) and RPE ( P = .77, d = 0.1) between groups. Significant improvements were observed in 30-15IFT (SSG: 4.1%, d = 1.5; HIT-COD: 4.2%, d = 1.7), RSAmean (SSG: −2.2%, d = 1.0; HIT-COD: −1.9%, d = 1.0), RSAbest (SSG: −2.0%, d = 0.9; HIT-COD: −2.1%, d = 1.1), MAT (SSG: −7.2%, d = 1.7; HIT-COD: 5.7%, d = 1.5), defensive movement test (SSG: −5.1%, d = 2.1; HIT-COD: −5.8%, d = 1.8) and control dribble test (SSG: −3.4%, d = 1.0; HIT-COD: −2.6%, d = 1.0). The only significant group × time interaction was found ( P = .032, [Formula: see text] = 0.24), with SSG improving 1 min shooting (22.4%, d = 1.0) and HIT-COD performing slightly worse (−2.6%, d = 0.1) after a 4-week intervention. The current study suggests that using SSG is more effective than HIT-COD for female collegiate basketball players in pre-season, since SSG improves physical performance and basketball-specific movements as well as shooting abilities after a 4-week intervention.

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.

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.
