Abstract:

The purpose of this study was to investigate the amount of some biomechanical variables (fly angle/land, horizontal displacement HD, angle of knee and hip, impulse and braking impulse) and electromyography (Area under curve AUC, Time Before Peak TBP and Time After Peak TAP) for targeted muscle groups in leg (LAT. GASTRO , TIB.ANT., RECTUS FEM., BICEPS FEM.).The subjects (10 M, age 20 -24 years) who were participated in Iraqi league during spike in volleyball. The technical that depended to record muscle activity was (Myotrace 400 from Noraxon company) and to determined biomechanical variables we used (Techno DYNAFOOT©), DYNAFOOT2 software is compatible with computers, laptops and tactile tablets under Windows operating system and equipped with a Bluetooth connection. Also we used Casio digital high speed camera (320f/s) to investigate joint angle and analysed by Kinovea v.8.15 software. The result come to show us there is a significant differs between two types in EMG variables so in some biomechanics.
