    Mini handball is among the sports included as part of school physical education in Chileto improve children’s motor skills and to motivate their adherence to a healthy and active lifestylein response to concerns about this country’s high level of childhood obesity. To this end, non-linearpedagogy (NLP) has been used to develop motor skills through mini handball in the school context.However, socioeconomic differences that influence the development of children’s motor skills havenot been considered to determine whether the methodology applies to everyone. The aim of thepresent observational study is to describe and compare the effectiveness of the previously appliedNLP methodology in two contrasting socioeconomic contexts to determine whether it helps todevelop motor skills through mini handball in both school contexts. The Levine test was usedto determine the homogeneity of the variances (p < 0.05), as the distribution of the data was notnormal. The Kruskal–Wallis H statistical test was used to analyse within-group data. Additionally,the Mann–Whitney U test was applied for comparisons between groups. The results show significantimprovements in the acquisition of the expected motor skills specific to mini handball. Additionally,a shortening of the gap was evidenced between the groups during the training process, with nosignificant differences at the end of the progression. Therefore, the investigated NLP is equally aseffective for schoolchildren in two opposite socioeconomic contexts.

    Introduction: over 80% of children and adolescents fail to meet physical activity recommendations, leading to declines in muscular and cardiorespiratory fitness and rising obesity rates. Exergames—digital games requiring physical movement—are a promising tool to promote activity in youth.Objective: to determine the effects of exergames on muscular fitness, cardiorespiratory fitness,and body composition in children and adolescents.Methodology: a search was conducted in Web of Science, Scopus, CINAHL, and PubMed databases, including randomized controlled trials published in the last 10 years. Studies were excluded if they involved participants with disabilities or used exergames for rehabilitation orhospital-based interventions.Results: a total of ten studies were included: three out of five studies reported improvementsin muscular fitness, seven out of nine in cardiorespiratory fitness, and five out of nine in bodycomposition. The most effective interventions occurred 2–3 times per week, for 40–60 minutesper session, over at least 12 weeks.Discussion: while outcomes are promising, differences in study design, duration, and assessment tools may have affected consistency across results.Conclusion: exergames appear effective for improving health-related fitness in children and adolescents, providing a fun and accessible way to increase physical activity through technology.
