Resumo: The present study aimed to analyze the effect of 24 weeks of AT with RFS on muscle activation and strength in overweight elderly women with osteopenia/osteoporosis. Thirty elderly women [66 (5) years] were randomly assigned to one of three interventions: CAM (moderate-intensity walking), CAM+RFS (low-intensity walking with RFS), or RFS (RFS alone). Muscle activation (EMGS) and knee flexor and extensor strength were measured, respectively, by surface electromyography and dynamometry, pre-intervention and after 12 and 24 weeks. Knee extensor EMGs and knee flexor strength increased similarly across all interventions at 24 weeks (p<0.05). A moderate effect size (ES, Cohen’s d) was observed in knee extensor EMGs (ES=0.65) for CAM+RFS compared to CAM. The ESs for knee flexor strength were −0.86 and −0.69, respectively for RFS and CAM+RFS compared to CAM. Therefore, interventions based on the RFS method showed similar strength gains, however, elderly women can achieve long-term neuromuscular gains over 24 weeks.

Trinta mulheres idosas [66 (5) anos] foram aleatoriamente designadas para uma das três intervenções: CAM (caminhada de intensidade moderada), CAM+RFS (caminhada de baixa intensidade com RFS) ou RFS (RFS sozinho). A ativação muscular (EMGS) e a força dos flexores e extensores do joelho foram mensuradas, respectivamente, por eletromiografia de superfície e dinamometria, pré-intervenção e após 12 e 24 semanas. O EMGs dos extensores do joelho e a força dos flexores do joelho aumentaram de forma semelhante em todas as intervenções em 24 semanas (p<0,05). Um tamanho de efeito moderado (ES, Cohen’s d) foi observado na EMGs dos extensores do joelho (ES= 0,65) para o CAM+RFS em comparação com o CAM. Os ESs para a força dos flexores do joelho foram −0,86 e −0,69, respectivamente para RFS e CAM+RFS em comparação com CAM.  Portanto, as intervenções baseadas no método de RFS apresentaram ganhos de força semelhantes, no entanto, mulheres idosas podem alcançar ganhos neuromusculares de longo prazo ao longo de 24 semanas.Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte2023-12-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/otherapplication/pdfapplication/pdfhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/1592810.15628/holos.2023.15928HOLOS; v. 6 n. 39 (2023): v.6 (2023)1807-1600reponame:Holosinstname:Instituto Federal do Rio Grande do Norte (IFRN)instacron:IFRNporenghttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/15928/3902http://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/15928/3903Brazil, 2023Brasil, 2023https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessTeixeira Bittar, Dra.
