Abstract Aim This systematic review aimed to determine the effect of aerobic exercise interventions, including high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT), on liver fat in adults. A secondary aim was to investigate the interaction between total weekly exercise volume and exercise-related energy expenditure and change in liver fat. Methods Relevant databases were searched to December 2020 for randomised trials, comparing HIIT to control, MICT to control, or HIIT to MICT. Studies were excluded if they did not implement ≥2 weeks intervention or assess liver fat using magnetic resonance-based techniques. Weighted mean differences and 95% confidence intervals (CI) were calculated. Regression analyses were undertaken to determine the interaction between weekly exercise volume in minutes and kcal with change in liver fat %. Results The search returned 28,262 studies of which 19 were included involving 745 participants. Both HIIT and MICT elicited moderate reductions in liver fat % when compared to control (HIIT:-2.85%, 95%CI:-4.86 to -0.84, p=0.005, I 2=0%, n=114, low certainty evidence; MICT:-3.14%, 95%CI:-4.45 to -1.82, p<0.001, I 2=5.2%, n=533, moderate certainty evidence). There was no difference between HIIT or MICT (-0.34%, 95%CI:-2.20 to 1.52, p=0.721, I 2=0%, n=177, moderate certainty evidence). Neither total exercise volume in minutes (β=0.0002, SE=0.0017, Z=0.13, p=0.89) nor exercise-related energy expenditure in kcal (β=0.0001, SE=0.0002, Z=-0.63, p=0.52) were related to changes in liver fat %. Conclusion HIIT elicits comparable improvements in liver fat to MICT despite often requiring less energy and time commitment. Further studies should be undertaken to assess the relative importance of aerobic exercise prescription variables, such as intensity, on liver fat.

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.

Intensity Training

Subjects performed high-intensity interval training (HIIT) and continuous moderate-intensity training (END) to evaluate 24-h oxygen consumption. Oxygen consumption during HIIT was lower versus END; however, total oxygen consumption over 24 h was similar. These data demonstrate that HIIT and END induce similar 24-h energy expenditure, which may explain the comparable changes in body composition reported despite lower total training volume and time commitment.

High Intensity Interval

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.
