Título: Relationship between limb movement speed and associated contraction of the trunk muscles / Paul W. Hodges and Carolyn A. RichardsonAutor: Hodges, Paul W.
Notas: Rapid shoulder movement is preceded by contraction of the abdominal muscles to prepare the body for the expected disturbance to postural equilibrium and spinal stability provoked by the reactive forces resulting from the movement. The magnitude of the reactive forces is proportional to the inertia of the limb. The aim of the study was to investigate if changes in the reaction time latency of the abdominal muscles was associated with variation in the magnitude of the reactive shoulder flexion at three different speeds (fast, natural and slow)Registros relacionados: En: Ergonomics. - London [etc.]. - Vol. 40, nº 11, November 1997 ; p. 1220-1230Materia / lugar / evento: Ergonomía Postura Lumbalgia Contracciones musculares Lesiones musculares Tiempo de reacción Métodos de análisis Otros autores: Richardson, Carolyn A.
