Eighteen effects from 17 RCTs [11,12,13,14,15,16,18,19,20,21,22,23,24,25,26,27,28] of 563 participants were included in the review (Table 1). Of the 17 included studies, 10 enrolled obese subjects [11,12,13,16,20,21,23,26,27,28], 1 included normal weight and obese subjects [39], and 6 included normal weight subjects [14,18,19,22,24,25].…”

“…In recent years, a number of experimental studies compared the effects of HIIT and MICT on CRF in children and adolescents, but the findings were inconsistent and inconclusive. Some intervention studies demonstrated that HIIT intervention stimulated significant increases in relative CRF when compared with MICT [11,12,13,14], while other studies did not observe any difference between these two methods [15,16,17,18,19,20,21,22,23,24,25,26,27,28]. Although there have been some systematic review suggested that the effect of HIIT on CRF is better than MICT [29,30], they focused on obese populations [30], or compared effect sizes with a non-exercise control group rather than a MICT group [31].…”

Enhancing cardiorespiratory fitness (CRF) can lead to substantial health benefits. Comparisons between high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on CRF for children and adolescents are inconsistent and inconclusive. The objective of this study was to perform a meta-analysis to compare the effects between HIIT and MICT on CRF in children and adolescents. We searched MEDLINE, PubMed, Web of Science, and Google Scholar to identify relevant articles. The standardized mean differences (SMD) and 95% confidence intervals (95% CI) were calculated to determine the pooled effect size of HIIT and MICT on CRF. A total of 563 subjects from 17 studies (18 effects) were identified. The pooled effect size was 0.51 (95% CI = 0.33–0.69) comparing HIIT to MICT. Moreover, intervention duration, exercise modality, work and rest ratio, and total bouts did not significantly modify the effect of HIIT on CRF. It is concluded that compared with endurance training, HIIT has greater improvements on cardiorespiratory fitness among children and adolescents.

“…The short-interval training programs consisted of training performed at intensities >90% VO 2peak or HR max for 30 s to 2 min intervals with 30 s to 1 min recovery (Corte de Araujo et al, 2012;Xiuming, 2014;Murphy et al, 2015;Lazzer et al, 2017). The long-interval training programs consisted of training performed at intensities of 80% VO 2peak or 85-100% HR max fort 2-4 min intervals with 1-3 min recovery (Koubaa et al, 2013;Starkoff et al, 2014;Mahgoub and Aly, 2015;Dias et al, 2018;Morrissey et al, 2018). The majority of the MICT programs consisted of training performed at 60-80% HR max or 60-70% VO 2peak for 30-40 min.…”

The main objective of this meta-analysis was to compare the effectiveness of high-intensity interval training (HIIT) and of moderate-intensity continuous training (MICT) on cardiometabolic health in childhood obesity and determine whether HIIT is a superior form of training in managing obese children's metabolic health. Methods: Relevant studies published in PubMed, Web of Science, Embase, the Cochrane Library, EBSCO, and CNKI were searched, restricted to those published from inception to 1 October 2019. Only randomized controlled trials (RCTs) depicting the effect of HIIT on childhood obesity were included. Results: Nine RCTs involving 309 participants were included in the meta-analysis. Among the 309 participants, 158 subjects were randomized for HIIT, while the others were randomized for MICT. Significant differences were observed in the body weight (mean difference [MD] = −5.45 kg, p = 0.001), body mass index (BMI; MD = −1.661 kg/m 2 , p = 0.0001), systolic blood pressure (SBP; MD = −3.994 mmHg, p = 0.003), and diastolic blood pressure (DBP; MD = −3.087 mmHg, p = 0.0001) in the HIIT group relative to the baseline values. Similar effects were found in the MICT group, as depicted by the significantly decreased values for body weight (MD = −4.604 kg, p = 0.0001), BMI (MD = −2.366 kg/m 2 , p = 0.0001), SBP (MD = −3.089 mmHg, p = 0.019), and DBP (MD = −3.087 mmHg, p = 0.0001). However, no significant differences were observed in the changes in body weight, BMI, SBP, or DBP between the HIIT and MICT groups. Furthermore, our studies showed that both HIIT and MICT could significantly improve VO 2peak (HIIT, MD = 4.17 ml/kg/min, 95% CI: 3.191 to 5.163, p = 0.0001; MICT, MD = 1.704 ml/kg/min, 95% CI: 0.279 to 3.130, p = 0.019). HIIT also showed more positive effects on VO 2peak (SMD = 0.468, 95% CI: 0.040 to 0.897, p = 0.006) than MICT. Conclusion: HIIT positively affects the cardiometabolic risk factors in childhood obesity. Similar positive effects on body composition and blood pressure were established. Moreover, HIIT can improve cardiorespiratory fitness more significantly than MICT. These findings indicate that HIIT may be an alternative and effective training method for managing childhood obesity.

“…During the 3-month program, exercise training consisted in supervised moderate-to-vigorous intensity exercise for 180 min/week. Each session mostly involved aerobic exercise, including training circuit, boxing, basket-ball and Nordic walk, with alternating short periods of high-intensity exercise interspersed among periods of lower intensity, as previously described [20].…”

Obesity in children is associated with vitamin D (VD) deficiency and cardiometabolic abnormalities. To analyze the effects of VD supplementation in adolescents with obesity enrolled in a weight-loss program. Adolescents with obesity (n=26) and with normal weight (n=23; controls) were matched for age, sex, and puberty stage. The obesity group followed a 3-month weight-loss program that combined a reduced caloric intake with interval training physical activity and during which they received or not VD supplementation (4000 IU/d) (n=13/group; random assignation). The anthropometric parameters (BMI z-score, fat mass); serum levels of 25(OH)D, calcium and parathyroid hormone (PTH), cardiometabolic factors (triglycerides, HDL, and LDL cholesterol), fasting glucose and insulin, and homeostasis model assessment of insulin resistance index; diastolic, systolic and mean blood pressure, and inflammatory status (C-reactive protein, CRP) were measured at baseline and at the end of the 3-month program. At baseline, 25(OH)D concentration was lower and VD insufficiency (25(OH)D levels <50 nmol/L) rate was higher (73% vs 22%) in the obesity than in the normal-weight group. All cardiometabolic factors were altered in the obesity compared with the normal-weight group. After the 3-month weight-loss program, 25(OH)D levels was >50 nmol in all adolescents with obesity, but only in 46% of normal-weight adolescents. Moreover, the weight-loss program improved the cardiometabolic factors, inflammatory status (CRP) and physical performance, but VD supplementation did not have any additional effect. Analysis only of the adolescents with obesity and VD deficiency (25(OH)D <50 nmol/L) at baseline showed a significant correlation between the change in PTH and CRP (p=0.02) in the supplemented obesity group, while the increase in 25(OH)D only tended to be correlated with CRP decrease. Vitamin D supplementation could reduce VD insufficiency in adolescent with obesity, but does not have any additional effect on cardiometabolic factors when combined with a weight-loss program.
