“…Five (50% of total) articles were classified as randomized controlled trials [25,26,[34][35][36]. Three articles were classified as nonrandomized controlled trials [27,30,31] (two groups with pre-and postassessments but without randomization). Furthermore, one article had a crossover design [33], whereas another had an observational design [32] (the experimental group was only assessed once at the end of the intervention).…”

“…Table 1 shows the results of the risk of bias assessment. Random assignment of participants to intervention (40% of articles did not fulfill this criterion) [27,[30][31][32], random selection of participants for assessment (0% of articles fulfilled this criterion), and follow-up rate of 80% or more (30% of articles did not fulfill this criterion) [26,27,31] were the most important sources of bias detected in the selected articles.…”

“…Table 2 displays the participants characteristics in each study. Three articles were focused on obese children [27,33,34], whereas 7 were focused on obese adolescents [25,26,[30][31][32]35,36]. Sample sizes ranged between 7 and 79 participants per study, a total of 335 participants (49.25% girls).…”

“…Session durations typically ranged between 40 and 60 min except for one intervention that required a total of 5 h/day of physical activity [32]. A total of 6 articles conducted aerobic training in the range of 60-75% of maximal heart rate [27,31,35], at the first ventilatory threshold [26], at 70% of the maximal aerobic speed [36], or at the ventilatory anaerobic threshold [34]. One article conducted resistance training at 50-85% 10 repetition maximum (RM) [30].…”

“…However, higher HRV values are typically present in individuals with high fitness levels or after exercise [23]. In this regard, physical activity such as aerobic training [24], recreational soccer [25], highintensity training [26], or judo [27] are used as interventions to increase HRV and thereby decrease sympathetic modulation.…”

Physical Exercise Improves Heart-Rate Variability in Obese Children and Adolescents: A Systematic Review

Background: Childhood obesity has negative impact on heart-rate variability (HRV) and, thereby, on the cardiovascular health of children and adolescents. Thus, physical-exercise interventions were proposed to increase HRV. The present systematic review aims to provide an up-to-date analysis of research on the effect of physical-exercise interventions on HRV in obese children and adolescents. Methods: An electronic search of the literature was performed, and 10 articles were included. PRISMA guideline methodology was employed. Results: Physical-exercise interventions predominantly involved aerobic training; however, alternative training programs, including judo or recreational soccer, were found. The duration of intervention ranged from 6 to 24 weeks, with a training frequency of between 2 and 7 times per week. The duration of sessions typically ranged from 40 to 60 min. Conclusions: Results of the included articles indicated that physical-exercise intervention increased the HRV and thereby the autonomic modulation of obese children and adolescents. This is significant, as HRV is associated with cardiovascular health. Such physical-exercise interventions are crucial to reduce weight and improve cardiovascular health in children and adolescents, thereby achieving a sustainable future.

Background Obesity in children has become one of the key concerns of the World Health Organization, and the incidence of related non-communicable diseases is also rising. This study evaluates the effect of family sports participation on the treatment and prevention of obesity in children aged 0–14 years by systematic analysis. Method A literature review from 2000 to 2020 was conducted. According to PRISMA-IPD (Preferred Reporting Items for MetaAnalyses of individual participant data) guidelines. The two researchers independently assessed the risk and bias of the articles, obtained a comprehensive, high-quality result, and extracted the data based on the Cochrane intervention system review manual. Randomized controlled trials (RCTs) were selected from the searches that used family sports interventions or family sports combined with dietary adjustments and behavioral habits change. Only studies targeting overweight or obese children aged 0–14 years were included. Results The search resulted in a total of 16 studies. Across all 16 studies, there were a total of 1680 participants in the experimental groups and 1701 participants in the control groups. The results are as follows: body mass index (BMI) (SMD-RE = − 4.10, 95% CI (− 0.84 to 0.02), Z = 1.88, p = 0.06); Body weight (SMD-RE = − 0.77, 95% CI (− 1.53 to − 0.01), Z = 2.00, p = 0.05); Waist circumference (SMD-RE = − 0.45, 95% CI (− 1.36 to 0.47), Z = 0.96, p = 0.34); and Body fat rate (SMD-FE = − 0.06, 95% CI (− 0.22 to 0.11), Z = 0.69, p = 0.49). Hence, through family sports intervention among obese children, juvenile and obese body composition—BMI, body weight, waist circumference, and body fat rate—are all reduced. But only body weight was statistically significant. Conclusions Compared with the samples without family sports, the weight of obese children participating in family sports decreased, but there were no significant differences in other relevant physical indicators. Follow-up research should examine large-scale clinical trials with family sports as a single factor intervention, which are needed to provide stronger evidence of the intervention effect. However, family activities can help obese children grow and develop by improving their exercise capacity, enhancing their lifestyles, and facilitating communication and relationships with their parents. In the future, long-term sports training plans for children with obesity should be implemented.

Introduction To master judo skills, athletes must maintain maximum flexibility, agility, speed, and endurance. It is known that strength training can improve athletes’ competitive abilities and physical conditioning. Still, there is no consensus in the literature about the impacts of the CORE strengthening on the physical fitness of young judo practitioners. Objective Analyze the influence that CORE strengthens on the physical fitness of young judo practitioners. Methods 18 young athletes were randomly divided into a control training group, with routine activities, and an experimental training group, in which a protocol of core strengthening was also inserted. The article uses mathematical statistics to analyze the relationship between the physical conditioning of judo athletes and the structural characteristics of their technical training. Results No significant differences were identified between the two groups regarding muscle activation time or amplitude changes in the electrocardiogram (P>0.05). There was a significant difference in the results of the two groups in the static suspension test (P<0.05). The level of forearm endurance in the elite judokas group was higher than that in the common judo group(P<0.05). There is no apparent interaction between the forearm strength data (P>0.05). Conclusion It was found that strengthening the CORE can help improve the physical fitness of young judo athletes. More attention is recommended to young judo athletes by inserting CORE strengthening in their regular training. Evidence Level II; Therapeutic Studies - Investigating the result.
