“…Nonetheless, the relationship between muscle strength and LBM (whole-body or regional) is well stated [37]. This relationship has been found to be stronger (R 2 = 0.70) when the leg strength is not isometric, but isotonic [38]. In our study, the relationship between LBM and the isometric force reached a mean statistical force of (R 2 = 0.57).…”

Physical activity (PA) can bring incalculable benefits to people throughout the aging process. The objective of this study was to determine the relationships between the leg and arm strength, body composition and balance of elderly people. Twenty-one people (9 men and 12 women) over 60 years of age voluntarily participated in this study. Bioimpedance tests were carried out to obtain body mass data, manual dynamometer tests and the lower limbs test were conducted to obtain strength values, and the stork balance stand test was conducted to assess static balance. As a result, medium-high correlation coefficients were obtained between the aforementioned dependent variables. The highest value corresponded to the relationship between the results of the dominant hand strength test (right hand in all participants) and the lean body mass (LBM) of the participant (R 2 = 75%, p < 0.001). The results indicated that strength capacity, recorded by dynamometry, and balance ability have a direct relationship with the body composition of the subject, especially with their lean body mass. These data suggest that a greater lean body mass can provide greater strength and balance in the elderly, so it would improve or have greater duration the functionality and independence of the person, thereby justifying direct benefits in people and indirect benefits in public administrations that finance these social issues.

“…4 Conversely we have also shown that muscular power is strongly correlated and can therefore be predicted by various body parameters, such as whole body mass and lean body mass. 24 The frail phenotype stratifies grip strength values by gender and BMI quartile. The trigger for the development of the frailty syndrome appears to be strongly associated with grip strength 10 regardless of the remaining markers (physical activity, exhaustion, unintentional weight loss, and gait speed).…”

PURPOSE:To analyze the relationship of grip strength and physical function in institutionalized older people. METHODS: One hundred and fifty-seven nursing home residents of seven different long-stay institutions underwent evaluation of body composition, cognitive function, grip strength, mobility, balance (balance scale test BERG and single-leg stance test) and gait speed. RESULTS: Volunteers had no impairment of cognitive function, functional mobility, balance or gait speed. Men had higher grip strength and achieved higher scores in BERG. Fittest volunteers (i.e., P 75 to P 100 ) had better functional mobility, BERG and gait speed; less fit volunteers (i.e., P 0 to P 25 ) were taller and had better gait speed. The grip strength was independently associated with functional mobility and balance in the single-leg stance test only in females. The cognitive function (female, P 25 to P 75 , male, total sample) and age (male, total sample) showed a tendency to be mediators of functional mobility. Age and body weight seem to confound the gait speed, especially for females (P 25 to P 75 ), while cognitive function confound it in males (P 75 to P 100 ). However, age and body weight are significantly associated with gait speed (female, total sample). CONCLUSION: We can conclude that grip strength was independently associated with functional mobility and balance of institutionalized older women.

“…Com o aumento da idade associada ao sedentarismo, processos degenerativos no sistema nervoso central, ocorrem de forma acentuada e resultam em comprometimento do equilíbrio, da força muscular e desempenho energético. Tendo em vista esse quadro, o exercício físico é apontado como um fator de prevenção e tratamento de diversas doenças que tendem a surgir com o processo de envelhecimento (Brandão et al, 2018;Lopez et al, 2018;Raso et al, 2016).…”

Introdução: O envelhecimento vem aumentando ao longo das últimas décadas, com isso se aumenta o risco de declínio cognitivo, diminuição funcional e piora da qualidade de vida. A prática de exercício físico ganha destaque por seu caráter preventivo e/ou terapêutico, de custo baixo e acessível. A maioria dos estudos utilizam períodos longos de intervenção (6 meses ou mais), com exercícios aeróbios ou resistidos, no entanto são escassos os trabalhos que utilizam da metodologia de treinamento em circuito. O presente estudo avaliou os efeitos de 12 semanas de um programa de treinamento em circuito sobre aspectos funcionais, funções cognitivas e qualidade de vida de idosos. Metodologia: Vinte idosos foram submetidos a um programa de treinamento em circuito por um período de 12 semanas e avaliados no período pré e pós intervenção. Foram utilizados: questionário SF-36, Mini Exame do Estado Mental (MEEM), Time Get up and go (TUG), Teste de sentar e levantar, Teste de flexão de antebraço, Teste de velocidade de marcha de 6 minutos. Resultados: Os dados obtidos mostraram uma melhora de 26% na média do SF-36, 7% na velocidade da marcha para o teste de 6 minutos, e aumento de 1,6 pontos para o mini mental. Conclusão: O treinamento físico em circuito foi capaz de melhorar qualidade de vida, funcionalidade e cognição em idosos.
