Si bien el exceso de peso corporal es un problema multifactorial, que puede originarse por causas ambientales, genéticas y socioeconómicas, la evidencia apunta a la inactividad física y la adopción de estilos de vida poco saludables como sus principales causantes^5,6. En este contexto, estudios sobre población chilena, desarrollados en estudiantes universitarios, han reportado un alto número de conductas y factores de riesgo poco saludables, entre los cuales se identifican un alto número de horas sentados, consumo de alcohol y alimentos procesados (con un alto contenido de sal, grasas saturadas y azúcares simples), no respetar los tiempo de comida como el desayuno, hábito tabáquico, insuficientes horas de sueño, exceso de peso corporal e inactividad física, estando estos dos últimas directamente relacionadas con el desarrollo de enfermedades cardiovasculares^7-10.

This systematic review aimed to assess the available evidence on the effects of neuromuscular training on physical performance in older adults. A literature search was conducted across four databases (Psychology and Behavioral (EBSCO), Scopus, Web of Science and PubMed). The PRISMA guidelines were followed. The PEDro scale and Cochrane risk of bias tool were used to assess the quality of and risk of bias in the studies, respectively. The protocol was registered in PROSPERO (code: CRD42022319239). The outcomes were muscle strength, cardiorespiratory fitness, postural balance and gait speed. From 610 records initially found, 10 were finally included in the systematic review, involving 354 older people with a mean age of 67.3 years. Nine of them reported significant changes in at least one variable related to physical performance in the intervention compared to the control groups. The neuromuscular training caused significant improvements in postural balance, flexibility, cardiorespiratory fitness, strength power of the upper and lower limbs and autonomy. The available evidence indicates that neuromuscular training has a positive effect on some variables of physical performance, especially in postural balance; however, the methodological quality and certainty of the evidence in the available literature are limited. Therefore, a greater number of high-quality studies are required to draw definitive conclusions.

Background/Objectives: Executive functions—including inhibitory control, working memory, and cognitive flexibility—are fundamental for children’s learning and development. Physical activity is recognized as a key factor that enhances these functions through neurobiological and structural brain adaptations. This narrative review aims to synthesize current evidence on the relationship between physical activity, executive functions, and brain outcomes in children. Methods: A narrative review was conducted using systematic evidence search across PubMed, Scopus, and Web of Science until August 2025. Search terms encompassed physical activity, executive functions, and brain mechanisms. Eligible studies included randomized controlled trials, longitudinal and cross-sectional studies, systematic reviews, and meta-analyses that examined executive function domains and brain-related outcomes in children, with or without neurodevelopmental disorders. Results: The evidence reviewed highlights that acute physical activity improves inhibitory control, working memory, and cognitive flexibility, primarily through enhanced neurotransmission and cerebral oxygenation. Chronic interventions promote structural and functional brain adaptations, including improved white matter integrity and increased network efficiency. Benefits are observed in both neurotypical children and those with ADHD, with inhibitory control emerging as the most responsive domain. However, findings are moderated by intervention type, intensity, and duration, with heterogeneity across protocols. Conclusions: Physical activity is a promising strategy to support the development of executive and brain functions in childhood, with implications for education and clinical practice. Despite consistent short- and long-term benefits, further research is required to establish optimal prescriptions and evaluate sustained real-world impacts, particularly in children with neurodevelopmental disorders.

Background: Aging causes morphological and physiological changes, especially in the musculoskeletal and somatosensory systems, leading to sarcopenia and reduced postural balance, increasing the risk of falls and loss of independence. This study aimed to analyze the effects of a neuromuscular training program on postural balance, physical performance, and muscle strength in older Chilean women. Methods: The double-blind randomized controlled trial included 48 participants aged 65–80 who were divided into three groups: a control group (CG), a multicomponent training group (MCG), and a neuromuscular training group (NMG). Postural balance was assessed using a force platform with open eyes (OE) and closed eyes (CE) conditions, measuring ML velocity, AP velocity, mean radius, and area. Physical performance was evaluated with the Short Physical Performance Battery (SPPB), including static balance, 4-m walking speed, and 5× sit-to-stand chair test. Muscle strength was measured using a hydraulic hand dynamometer to record maximum grip force. Results: Significant time × group interactions in the CE condition were found for mean radius (F = 0.984; p = 0.017; ηp² = 0.184), AP velocity (F = 10.01; p = 0.001; ηp² = 0.312), and ML velocity (F = 4.30; p = 0.027; ηp² = 0.163). Significant pre–post differences in the NMG for mean radius (p < 0.001), AP velocity (p < 0.001), and ML velocity (p = 0.029) were observed, with no significant changes in CG. Significant time × group interactions were also found in the SPPB test score (F = 11.49; p < 0.001; ηp² = 0.343), gait speed (F = 5.513; p = 0.012; ηp² = 0.198), and sit-to-stand test (F = 5.731; p = 0.010; ηp² = 0.206), but not in the balance score (F = 2.099; p = 0.148). Handgrip strength showed no significant interactions (F = 3.216; p = 0.061; ηp² = 0.127). Conclusions: These findings suggest that neuromuscular training is a promising intervention to mitigate the decline in balance and physical function associated with aging, offering a targeted approach to improve the quality of life in the elderly.

La condición física corresponde a la capacidad fisiológica para realizar actividades de la vida diaria con normalidad, de manera segura, independiente, sin fatiga excesiva y que depende de la indemnidad de aptitudes físicas, tales como; fuerza, resistencia aeróbica, flexibilidad, agilidad y equilibrio dinámico⁸. El déficit en los componentes de la condición física han sido vinculados con discapacidad, mayor riesgo de caídas, fracturas y disminución en la calidad de vida^9,10.

This systematic review and meta-analysis aimed to assess the available body of published peer-reviewed articles related to the effects of Olympic combat sports (OCS), compared with active/passive controls, on balance, fall risk, or falls in older adults. The TESTEX and GRADE scales assessed the methodological quality and certainty of the evidence. The protocol was registered in PROSPERO (code: CRD42020204034). From 1496 records, eight studies were included, involving 322 older adults (64% female; mean age = 71.1 years). The TESTEX scale revealed all studies with a score ≥ 60% (moderate-high quality). The GRADE scale indicated all studies with at least some concerns, up to a high risk of bias (i.e., was rated very low). Meta-analyses were planned, although the reduced number of studies precluded its incorporation in the final manuscript. Only two from six studies that assessed balance found improvements after OCS compared to controls. No differences were found between OCS vs. control groups for fall risk or falls. The available evidence does not allow a definitive recommendation for or against OCS interventions as an effective strategy to improve balance and reduce the fall risk or falls in older adults. Therefore, more high-quality studies are required to draw definitive conclusions.
