    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.

    Five-repetition sit-to-stand test validation in adolescents and adults with intellectual disabilities
    (2024) Farías-Valenzuela, Claudio; Shepherd-Shepherd, Catalina; Ferrero-Hernández, Paloma; López-Sánchez, Guillermo F.; Espoz-Lazo, Sebastián; Cofré-Bolados, Cristian; Val-Martín, Pablo del; Victo, Eduardo R. de; Ferrari, Gerson
    This study aims to validate the five repetition sit to stand test (5R-STS) test as a measure of strength and functionality in adolescents and adults with intellectual disabilities (ID). The sample was made up of 159 subjects with ID (85 adolescents and 74 adults) of both sexes, with average age of 18.36 (5.26) years, belonging to four special educational centers from Santiago, Chile. Absolute (AHGS) and relative (RHGS) handgrip strength and countermovement jump (CMJ) were considered as muscle strength evaluation tests. The timed up and go (TUG) and agility test 4×10 m were considered as functional tests. Spearman and intraclass correlations, as well as Bland-Altman plots were used to establish the respective correlations. The average values obtained in the 5R-STS test (s) in adolescents were 6.55 and 7.24, while in adults they were 6.82 and 7.17 for men and women, respectively. Significant correlations (p=<0.05) are established between the 5R-STS test with AHGS (r= -0.48) and RHGS (r= -0.54), CMJ (-0.53), 4×10 m test (-0.50) and TUG (-0.49), as well as in the analysis of agreement between 5R-STS and the TUG (ICC=0.74) and agility 4×10 m (ICC=0.61) tests, both in adolescents and adults of both sexes. The 5R-STS test is a valid, simple and safe tool to evaluate general and lower extremity muscle strength. Its use is suggested as a simple measure for monitoring functional capacity by professionals in educational and health contexts for the adolescent and adult population with ID.
