Idosos, Eletroestimulação, Treinamento resistido, Limiar de dor e Cargas externasResumo
Objetivo: Pesquisas sugerem relação entre eletroestimulação e treinamento de força para otimizar a função neuromuscular, mas os efeitos das diferentes configurações geram incertezas sobre variáveis manipuláveis, incluindo cargas internas e externas. Objetivo: Investigar a relação entre o limiar sensitivo e a carga externa do treinamento de força. Métodos: Estudo observacional transversal dividido em três etapas: envio de questionários eletrônicos; aplicação do Termo de Consentimento, coleta de dados antropométricos e avaliação dos limiares de dor e sensibilidade; após 72 horas, teste de preensão manual e predição de uma repetição máxima (1RM). Utilizou-se SPSS versão 26.0 para análise estatística. Resultados: Foram avaliadas 16 mulheres senescentes (60,25 ± 6,48 anos; IMC 28,59 ± 5,09 kg/m²). A força dinâmica média no supino, leg press e remada foi de 62,61 ± 14,08 kg; a força isométrica, 27,38 ± 6,15 kgF. O limiar médio de sensibilidade foi 8,1 ± 1,9 mA e o de dor, 114,15 ± 56,00 mA. As correlações entre força dinâmica e limiares de sensibilidade (r = -0,137; p = 0,614) e dor (r = 0,391; p = 0,135) não foram significativas, assim como para força isométrica (r < 0,1; p > 0,05). Conclusão: Não foram identificadas métricas que correlacionassem percepções internas de intensidade com cargas externas. Implicações: O estudo questiona a eficácia do sistema usual de estimativa de cargas externas baseado em percepções internas, mostrando inconsistência entre as duas medidas.
