AB  - The purpose of this study was to compare the electromyogram (EMG) activity of the 
      trunk musculature for long throwers and short throwers during the side 
      medicine-ball throw. The study consisted of 2 sessions. Thirty athletes performed 
      the side medicine-ball throw (S-MBT) in the first session. The top 5 subjects 
      (long throwers) and the worst 5 subjects (short throwers) in the performance of 
      the S-MBT proceeded to the second session. These subjects performed the fast side 
      medicine-ball throw (FS-MBT) and the isometric maximal trunk rotation torque 
      (IMTRT) test after applying surface electrodes bilaterally to the following 
      muscles: pectoralis major, rectus abdominis, external oblique, and latissimus 
      dorsi. The value of IMTRT in the left turn in long throwers was significantly 
      greater (p < 0.05) than that recorded for short throwers, whereas no difference 
      was observed in the right turn. The velocities of the medicine ball using 2-kg, 
      4-kg, and 6-kg medicine balls were significantly different (p < 0.01-0.001) 
      between long throwers and short throwers The examination of EMG activity in each 
      muscle group for long throwers and short throwers revealed that the major 
      difference between the 2 groups is EMG activity of the left external oblique. 
      These results suggest that the EMG activity of the external oblique on either 
      side is an important factor for FS-MBT.
