The percentage changes of the forces from pre-training to post-training in control and training groups. The maximum voluntary contraction force of 90° of elevation for the deltoid and supraspinatus was measured with abduction (ABD) in the scapular plane at 90° of humeral elevation with neutral axial rotation. The force of external rotation (ER) for posterior rotator cuff muscles was tested with the arm at the side and 90° of elbow flexion. The force of horizontal abduction for lower trapezius was tested in a prone position with horizontal abduction in 120° of elevation. The force of 135° of elevation for the serratus anterior was measured with 135° of abduction in the scapular plane. (*p < 0.05)
