Muscle strength training program in nonagenarians – a randomized controlled trial

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

OBJETIVO:

O objetivo do estudo é melhorar a capacidade funcional e a qualidade de vida (QV) de nonagenários por meio da implementação de um programa de treinamento aeróbico e de força individualizado em um centro geriátrico residencial.

DESENHO DO ESTUDO:

Estudo controlado randomizado.

METODOLOGIA:

Vinte e seis mulheres idosas foram randomizadas em grupo controle (CG) e grupo intervenção (SG). O SG realizou um programa de força com 12 semanas de duração de duas sessões semanais. As ferramentas de avaliação usadas antes e após a intervenção foram o Índice de Barthel das atividades da vida diária, o teste Five-to-Stand (FTSTS) e o Timed Up and Go (TUG) com sensores Wiva®.

RESULTADOS:

O SG manteve as pontuações no Índice de Barthel e melhora no FTSTS; o GC apresentou redução significativa nos dois testes. O teste de equilíbrio dinâmico mostrou diferenças significativas entre os grupos para as variáveis: Sit to Stand, pico da velocidade angular, amplitude anteroposterior, giro, posição sentada, tempo total e velocidade.

CONCLUSÕES:

Os programas de intervenção de força muscular podem ajudar a promover estilos de vida saudáveis nesta população para a manutenção da autonomia, a melhora da função e o equilíbrio.
