Resumo
Introdução: à medida que são registrados dados sobre o envelhecimento, também
são observados o aumento de doenças crônicas não transmissíveis e alterações na
composição corporal nos idosos que contribuem em quadros de maior
vulnerabilidade. Alterações como redução da massa magra e aumento do percentual
de gordura impactam diretamente na redução de massa muscular e óssea. Neste
contexto, investigar se o percentual de gordura apresenta uma relação inversa com
a funcionalidade e a massa magra uma relação direta em mulheres idosas ativas é
importante para estabelecer o impacto dessas alterações na funcionalidade.
Objetivo: analisar a influência da composição corporal (gordura e massa magra) na
funcionalidade de mulheres idosas ativas. Métodos: trata-se de um estudo
observacional transversal onde foram avaliadas 48 mulheres idosas com idade igual
ou superior a 60 anos. O estudo foi realizado em duas fases, onde na primeira fase
foi realizada a caracterização da amostra com avaliações antropométricas para
calcular o IMC e testes clínicos para avaliar as variáveis de performance física,
equilíbrio funcional e força de preensão palmar. Na segunda fase foi realizada a
avaliação da composição corporal utilizando a absorciometria de raios-x de dupla
energia (DXA). Para a caracterização da amostra e desfechos foram apresentados
em média, desvio padrão, número absoluto e porcentagem. Para avaliar a
normalidade dos dados foi utilizado o teste de Shapiro-Wilk. A avaliação das
relações das variáveis foi realizada por meio do teste de correlação de Pearson ou
Spearman de acordo com a normalidade. O nível de significância utilizado foi de
p<0,05. Resultados: foram encontradas relações positivas e significantes (p<0,05)
entre o percentual de gordura com o tempo de execução do teste sentar e levantar 5
vezes e TUG, e o total de massa magra com a dinamometria manual. Ainda, foi
notada relações negativas e significantes entre o percentual de gordura com a
dinamometria manual (p<0,05). Conclusão: conclui-se que o percentual de gordura
apresentou uma relação inversa com a funcionalidade (sentar e levantar e TUG) e a
massa magra uma relação direta (força de preensão palmar) em mulheres idosas
ativas.
Introduction: As data on ageing is recorded, there is also an increase in chronic non-communicable diseases and changes in body composition in the elderly which contribute to greater vulnerability. Changes such as a reduction in lean mass and an increase in fat percentage have a direct impact on a reduction in muscle and bone mass. In this context, it is important to investigate whether fat percentage has an inverse relationship with functionality and lean mass a direct relationship in active elderly women in order to establish the impact of these changes on functionality. Objective: To analyze the influence of body composition (fat and lean mass) on functionality in active elderly women. Methods: This was a cross-sectional observational study in which 48 elderly women aged 60 or over were assessed.The study was carried out in two phases. In the first phase, the sample was characterized with anthropometric assessments to calculate BMI and clinical tests to assess physical performance variables, functional balance and handgrip strength. In the second phase, body composition was assessed using dual-energy X-ray absorptiometry (DXA). To characterize the sample and the outcomes, means, standard deviations, absolute numbers and percentages were presented. The Shapiro-Wilk test was used to assess the normality of the data. The relationship between the variables was assessed using the Pearson or Spearman correlation test, according to normality. The significance level used was p<0.05. Results: Positive and significant relationships (p<0.05) were found between the percentage of fat with the time taken to perform the sit and stand test 5 times and the TUG, and total lean mass with manual dynamometry. A negative and significant relationship was also found between the percentage of fat and manual dynamometry (p<0.05). Conclusion: It can be concluded that the percentage of fat showed an inverse relationship with functionality (sit and stand and TUG) and lean mass a direct relationship (handgrip strength) in active elderly women.
