Potencia muscular: Romper el paradigma de fuerza para tratar sarcopenia

En la evaluación del desempeño muscular se debe de incorporar la evaluación de la potencia muscular, que se encuentra muy estrechamente relacionada con el desempeño funcional, y guiar las intervenciones terapéuticas para prevenir desenlaces como caídas.
