Treinamento de Potência em Idosos: Porque é Importante?

A potência e a força muscular são componentes importantes no processo de preservação da capacidade funcional e independência para realizar as atividades da vida diária em idosos, já que o processo de envelhecimento parece reduzir a força e potência muscular, resultante do declínio das funções neuromuscular e morfológica1 . Estima-se que a força e a potência possam reduzir em média de 20% a 40% entre os 70 e 80 anos e 50% após os 80 anos2 . Essas alterações estão relacionadas com a perda de massa muscular e força que ocorre com o envelhecimento denominada sarcopenia3 , predispondo o idoso a desenvolver osteopenia, osteoporose, diminuição do nível de atividade física e gasto calórico diário, além de diversas mudanças na composição corporal, como o aumento na adiposidade e gordura visceral.Referências 1.
