    Asociación entre la condición física y calidad de vida con la fragilidad en personas mayores
    (2022) Rodríguez-Gutiérrez, Salomé; Alarcón-Rivera, Miguel; Concha-Cisternas, Yeny; Valdés-Badilla, Pablo; Guzmán-Muñoz, Eduardo
    Introducción: El envejecimiento patológico provoca cambios anatomofisiológicos responsables de generar deterioro en la condición física y calidad de vida de las personas mayores. Así también se ha observado un aumento en la presencia de síndromes geriátricos como la fragilidad física. Objetivo: Determinar si existe asociación entre la condición física y calidad de vida con la fragilidad en personas mayores. Métodos: Estudio correlacional. Se incluyeron 84 personas mayores de 65 años (62 mujeres y 22 hombres) entre agosto y septiembre del año 2021 en las regiones metropolitana y Maule, Chile. Se midieron la condición física, calidad de vida y fragilidad. La condición física se evaluó con la batería Senior Fittnes Test y la calidad de vida fue medida con el cuestionario World Health Organization Quality of Life Old (WHOQOL-OLD). La fragilidad se determinó con el fenotipo de Fried. Se utilizaron tablas de contingencia para asociar las variables de estudio con la fragilidad a través de la prueba de ji cuadrado. Resultados: La fragilidad se asoció con algunos componentes de la condición física como fuerza del tren superior (p= 0,038), fuerza del tren inferior (p= 0,018), flexibilidad del tren inferior (p= 0,004), resistencia aeróbica (p= 0,038), agilidad y equilibrio dinámico (p= 0,002). También, se observaron asociaciones significativas con dimensiones de calidad de vida como autonomía (p= 0,007), actividades del pasado, presente y futuro (p= 0,018), participación social (p= 0,006) e intimidad (p= 0,038). Conclusión: Existe asociación entre fragilidad con dimensiones de calidad de vida y con variables de la condición física.

    Effectiveness of Olympic Combat Sports on Balance, Fall Risk or Falls in Older Adults: A Systematic Review
    (2022-01-04) Valdés-Badilla, Pablo; Ramirez-Campillo, Rodrigo; Herrera-Valenzuela, Tomás; Magnani Branco, Braulio Henrique; Guzmán-Muñoz, Eduardo; Mendez-Rebolledo, Guillermo; Concha-Cisternas, Yeny; Hernandez-Martínez, Jordan
    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.

    Effects of Neuromuscular Training on Physical Performance in Older People: A Systematic Review
    (2023-03-24) Concha-Cisternas, Yeny; Castro-Piñero, José; Leiva-Ordóñez, Ana María; Valdés-Badilla, Pablo; Celis-Morales, Carlos; Guzmán-Muñoz, Eduardo
    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.
