Influence of Externally Damping on Impact-induced Soft Tissue Vibrations and Muscle Responses in Landings
نویسندگان
چکیده
The aim of this study was to investigate the changes in activation of the musculoskeletal system in response to soft-tissue vibrations with different compression conditions (externally applied) in a drop-jump landing task. Twelve trained male participants were instructed to perform drop-jump landings from 3 heights in compression shorts (CS) and regular shorts without compression (CC). Externally induced soft-tissue vibration damping, i.e. reduced peak acceleration and increased damping coefficient, was associated with a significant decrease in muscular activity of the rectus femoris and the biceps femoris muscles during drop-jump landing from different heights. Therefore, a greater increase in the damping is associated with a greater decrease in muscle activity.

BACKGROUND Previous studies have not used neurophysiological methodology to explore the damping effects on induced soft-tissue vibrations and muscle responses. OBJECTIVE This study aimed to investigate the changes in activation of the musculoskeletal system in response to soft-tissue vibrations with different applied compression conditions in a drop-jump landing task.

متن کاملModification of soft tissue vibrations in the leg by muscular activity.
Vibration characteristics were recorded for the soft tissues of the triceps surae, tibialis anterior, and quadriceps muscles. The frequency and damping of free vibrations in these tissues were measured while isometric and isotonic contractions of the leg were performed. Soft tissue vibration frequency and damping increased with both the force produced by and the shortening velocity of the under...
متن کاملPartial External Soft Tissue Vibration Damping Decreases Local Oxygen Consumption
Soft tissue exposure to vibrations was shown to increase the muscle activity [1]. External soft tissue vibration damping, using compression apparel, was associated with an increase of the damping coefficient of the soft tissue compartments of the leg and a decrease of the muscle activity during vibrations exposure [2]. It is assumed, but not known, that a decrease in muscle activity induced by ...
متن کاملMuscle activity damps the soft tissue resonance that occurs in response to pulsed and continuous vibrations.
This study tested the hypotheses that when the excitation frequency of mechanical stimuli to the foot was close to the natural frequency of the soft tissues of the lower extremity, the muscle activity increases 1) the natural frequency and 2) the damping to minimize resonance. Soft tissue vibrations were measured with triaxial accelerometers, and muscle activity was measured by using surface el...
متن کاملBiomechanical Comparisons of Active and Unexpected Landings with Changes in Drop Height
The purpose of this study was to determine the differences of kinematics, impact force, soft-tissue vibration, and muscle activity between active (AL) and unexpected landing (UL). Twelve trained male volunteers were requested to land from self-made elevated platform at three heights (30, 45, and 60cm) in AL and UL conditions. During active landing, human body can adjust the landing strategy of ...
