Values are presented mean ± standard deviation (mm). MT, middle trapezius; RH, rhomboid major; HAB, shoulder horizontal abduction; Ext, shoulder extension; ExRot, shoulder external rotation; ExY, extension with Y. ^aThere is a significant difference from resting. ^bThere is a significant difference from HAB. ^cThere is a significant difference from Ext. *p < 0.05, **p < 0.01.
