유소년 축구선수의 킥 동작에 따른 운동역학적 분석

Abstract

We projected of analysis that was aimed at enhanced kick performance of football posture for adolescent athletes and was measured lower limb angle, displacement of plantar center of pressure(COP) were occurred during each inside kick and instep kick(long kick).<BR> Healthy adolescent athletes(n=10, male, age: 13.6±.52) were recruited for our project. Range of motion(ROM) over Hip, Knee and Ankle Joint were measured by three-dimensional analysis using inertial measurement units. COP of each kicking and support foot was measured from sensor insole. Statistical analysis of independent t-test was performed(p<.05).<BR> The results revealed that inside kick caused greater ROM than instep kick over the phase for preparing kick in almost all joints. Inside kick showed smaller ROM than instep kick over the phase for kicking. COP displacement of support foot from inside kick was smaller than instep kick with significant(p<.05) when the event of initial contact of support foot or toe-off of kicking foot from the ground arose.<BR> These results suggest inside kick and instep kick have the different tendency of ROM over joint angle of lower limbs each other and have the different tendency of behavior strategy for stability of center of body in football athletes when the foot for support of kicking contacted on the ground.
