EVALUATION OF MECHANICAL PROPERTIES OF KNEE EXTENSOR AND PATELLAR TENDON DURING SQUATTING BY MUSCLE CONTRACTION SENSOR METHOD
Keywords: MC sensor, squatting, mechanical property, muscle-tendon complex
AbstractThe purpose of this study was to investigate the mechanical properties of muscle-tendon can* during squatting. Fourteen males were participated in this study. The muscle activities of knee extensor during squatting were measured by surface electrompgraphy. The mechanical prop@ of knee extensor and patellar tendon were measured using a muscle contraction (MC) sensor. Muscle activities of the knee exten- during squatting showed a significant correlation to the MC signal. The mechanical properties of the knee extensor and patellar tendon were closely related to the angle of the knee joint MC signals of knee extensor shaved a consistency on each muscle related to patellar tendon. From these results, it is considered, that the method using an MC sensor is effective for evaluating the changes in dynamic tension in muscle-tendon complex during squatting.
