A Comparative Study on Neuromuscular Control Patterns during Side Cutting Depending on Direction Prediction Presence or Absence and Gender

PURPOSE This study aimed to identify the lower limb muscle activity based on direction prediction presence or absence and gender during side cutting in healthy college students. METHODS The participants included 14 males females (8 males; 6 females). All ran at full speed for a distance of 12m, side-cutting was carried out 45 degrees randomly indicated fixed direction. Simultaneously, data regarding vastus medialis, lateralis, semitendinosus, biceps femoris dominant leg were collected using an electromyography sensor, vertical acceleration inertial sensor attached pelvis. A sync webcam used obtaining initial contact stance period time. During 10 milliseconds (pre-activation) prior 50% phase (loading phase), average hamstring quadriceps ratio as variables. RESULTS pre-activation loading phase, medialis male group higher unexpected condition than expected condition. Furthermore, confirmed be under compared phase. CONCLUSIONS results suggest that risk anterior cruciate ligament injury may increase with unpredictable conditions. It is provide useful information identifying factors related knee general population.
