Relationship between natural muscle oscillation frequency and lower limb muscle performance during instrumented sit-to-stand and stand-to-sit movements on a novel device in sedentary subjects

Torres-Banduc et al. (2024)

Resumen

This 2024 study investigates the relationship between the natural oscillation frequency of muscles (a measure of tone) and functional performance during sit-to-stand movements. Results indicate that higher resting muscle frequency significantly correlates with better muscle force, power, and work, specifically in isotonic (constant resistance) testing modes.

Las pruebas isotónicas parecen ser más efectivas para evaluar la relación entre las propiedades mecánicas del músculo y el rendimiento funcional en poblaciones sedentarias. Esto proporciona una herramienta potencial para la evaluación no invasiva de la capacidad funcional de las extremidades inferiores.
