Title: Electromyographic analysis of selected muscles of lower extremity of kitesurfers. Objective: The goal of thesis is to determine muscle groups, which are the most active during the kitesurfing position and compare the values in increasing time spent in this position. Furthermore, to determine a degree of co-contraction level between m. quadriceps femoris and m. biceps femoris. According to the enlarging number of riders in kitesurfing population the goal is to compare results between professional and recreant riders and determine statisticaly significant differences. Methods: This thesis is a case study, where is analyzed the degree of muscle aktivity of lower extremity during the kitesurfing position. The research involved 6 persons of very specific selection consisted of professional riders and recreants. As an objectification method surface electromyography had been chosen and the normalized value between m. quadriceps femoris, m. gluteus maximus, m. biceps femoris, m. tibialis anterior, m. gastrocnemius and m. trapezius had been evaluated. Findings: The measurement results showed that the most active muscle during the kitesurfing position is m. quadriceps femoris of stance lower extremity even though after long-term stay. Furthemore, the results showed that professional riders apply more...
