Biomechanical analysis of the physical effects of riding the X-lider

The purpose of this study was to assess 5 different types of fundamental movements with Xslider and inline skate, through an examination of muscle activity patterns and kinematics. Visol DV Express program was used to capture the data, Kwon 3D 3.1 for windows was used to quantify the kinematical variables. 1) Straight motion exercise: rectus femoris, tibialis anterior, and gastrocnemius were active with the X-slider at the pushing leg phase. At the pulling leg phase, levels of hamstring and gastrocnemius activities increased. Inline skate used tibialis anterior and gastrocnemius as agonist muscles instead of quadricep groups. 2) Figure-8 exercise: X-slider produced high level of rectus femoris, tibialis anterior, and gastrocnemius activities. 3) Slalom exercise: Xslider activated many kinks of lower leg muscles especially crossing legs motion produced high adductor muscle activity. Tibialis anterior and gastrocnemius were mainly used for inline skate. 4) Rotation exercise: X-slider used most of lower leg muscles as if performing slalom. Gathering the legs together led to greater adductor muscles activity. Adductor muscle, tibialis anterior and gastrocnemius were used as agonist for inline skate. 5) While stopping: rectus femoris was highly used with X-slider and tibialis anterior and gastrocnemius were largely used with Inline skate.
