“…Our results are consistent with results of previous studies (Greening et al 2011, Vanhelst et al 2011, that showed better results on physical fitness values and decreases on body composition values in experimental group constituted by obese students (9months physical activity program, 2 sessions/week), or even was observed significant differences on body mass index (BMI), with decreases in experimental group and increases in control group, after a 12 months long physical activity program. the results of the current study are also congruent with results of a previous study (Alves et al 2017) in this area which were showed significantly decreases on body fat percentage in experimental group constituted by prepubescent girls (8-week concurrent training, 2 sessions/week). Dorgo et al (2009) verified the effectiveness of different physical training programs on physical fitness levels, however did not observed differences on body composition values.…”

Introduction: The aim of the study was to compare the effects of ten-week multicomponent training with different exercise frequencies on body composition (BC) and physical fitness (PF) in overweight and obese young children. Methods: 40 children, aged 12-15 (14.77±1.49), were randomly selected and assigned to experimental groups to train three times/week (EG1) or two times/week (EG2) for 10 weeks and a CG group (no training program). Results: It was shown that experimental groups (EG1 and EG2) improved similarly aerobic capacity (3.8% and 3.5%, respectively), muscular strength (29.7% and 25.2%), flexibility (6.1% and 9.9%), body mass index (5.0% and 4.6%), and body fat (6.4% and 5.6%) from pre-to post-training. CG group showed no significant improvements on BC and PF variables. Conclusion: Short-term multicomponent training seems to be effective on PF improvements, independently of the exercise frequency, in overweight and obese young children. However, it seems to be more effective to perform a multicomponent exercise training three times/week to improve muscular strength, body mass index, and decrease body fat percentage. This knowledge should be considered by professionals in physical education or youth sport in order to adapt practical tasks depending on the training purposes.

Some studies have shown that resistance training combined with plyometric training is more time-efficient and effective for fitness development. The degree and frequency of combined training might influence the benefit of training to maintain time. To better understand this phenomenon of the degree and frequency of combined training in pre-and early pubertal boys, we have provided a more specific recommendation for physical education teachers thus that they are able to prescribe an exercise plan for their students in the physical education setting. We aimed to investigate the effects of combined training followed by 12 weeks of a reduced/detraining period on physical fitness and anthropometric features in 8 to 12-year old boys. Forty-six healthy boys were randomly assigned to either an experimental group (EG, n = 31) or a control group (CG, n = 15). Besides regular physical education classes (PE), participants in the EG performed a combined training program (resistance and plyometric training) twice weekly for 12 weeks. In the CG, participants only underwent PE classes twice per week. Then, the trained boys were randomly assigned to either a reduced training group (RTG, n = 14) or a training cessation group (TCG, n = 17). The RTG continued a reduced combined training program once a week with PE for additional 12 weeks. In the TCG, participants only kept their PE classes twice a week for 12 weeks. We assessed physical fitness performances (biceps curl, leg power, and running speed) and anthropometric features at baseline, after 12 weeks of combined training, and after 12 weeks of reduced training/detraining. We observed a significantly greater decrease in biceps girth in the EG (p = 0.049, d = 0.636), as compared to the CG. With regard to the physical fitness measures after the 12-week combined training, the EG showed significantly greater increase on biceps curl (p = 0.005, d = 0.92) and standing long jump (p = 0.015, d = 0.8) in comparison with the CG, whereas a significantly greater improvement on 30 m sprint speed (p = 0.031, d = 0.707) was observed in the EG, as compared to the CG. With regard to detraining and reduced training, results indicated a significantly greater increase on this outcome in the RTG (p = 0.038, d = 0.938), as compared to the TCG. Resistance training combined with plyometric training can be a safe and effective way to enhance the selected aspects of physical fitness, as well as reduce muscular girth in boys aged between 8 and 12 years. The frequency of one session per week in the combined training seems to provide an additional benefit to prevent leg power of lower limb from rapid deterioration.

BackgroundSchools provide a favorable setting for health education, however, the most effective school-based exercise mode for improving physical fitness remains unclear. This network meta-analysis was designed to assess and rank the comparative efficacy of six exercise modalities on physical fitness indicators in a school-based setting.MethodsAn online search of the Web of Science, PubMed, SPORTDiscus, and Scopus databases was conducted. Randomized and quasi-randomized controlled trials were considered. Outcomes included measures of anthropometry and body composition, muscular fitness, and cardiorespiratory fitness. Data were pooled with a random effects model using the frequentist framework.ResultsA total of 66 studies with 8,578 participants (48% girls) were included. High-intensity interval training was the most effective intervention reducing body mass index (mean difference (MD) = −0.60 kg·m−2, 95% confidence interval (95%CI) = −1.04 to −0.15, p = 0.009), elevating VO2max (MD = 3.59 mL·kg−1·min−1, 95% CI = 2.45 to 4.74, p < 0.001), and 20-meter sprint performance (MD = −0.35 s, 95% CI = −0.55 to −0.14, p = 0.001). Aerobic training had the highest probability of reducing waist circumference (standardized mean difference (SMD) = −0.60, 95% CI = −0.88 to −0.32, p < 0.001). Active video games emerged as a promising modality for improving countermovement jump (MD = 2.43 cm, 95% CI = 0.06 to 4.80, p = 0.041) and shuttle running performance (SMD = 0.86, 95% CI = 0.29 to 1.43, p = 0.003). Strength training was the best exercise mode for improving standing long jump performance (SMD = 1.03, 95% CI = 0.07 to 1.98, p = 0.035) while combined training was rated the first for decreasing body fat percent (MD = −2.56%, 95% CI = −4.73 to −0.40, p = 0.022) and increasing push-up repetitions (SMD = 3.59, 95% CI = 0.81 to 6.37, p = 0.012).ConclusionSchool-based exercise interventions have multiple effects on physical fitness. The findings of this study will help to inform physical education teachers and coaches how best to deliver exercise programs in a school setting. Since the study was limited by the original research, the conclusions will require further verification using high-quality randomized controlled trials.Systematic Review RegistrationPROSPERO, Identifier: CRD42023401963.
