Abstract
Shoulder strength peak torque (PT) values were assessed. Concentric (CON)& eccentric (ECC) strength of the dominant (DCM) & nondominant (ND) extremities of 23 males were tested at 1.047 rad's on a Biodex® 2000 isokinetic dynamometer for the flexor (FL), extensor (EX), abductor (AB), adductor (AD), horizontal abductor (HB), horizontal adductor (HD), external rotator (ER), & internal rotator (IR) muscle groups. 3 submax & 3 maximal contractions were performed prior to a 3 max test. A pairedt-test compared CON vs CON & ECC vs ECC windowed PT data of identical muscle groups of the DOM & ND extremities.Results:Table DOM IR, ER & HD CON PT production is greater (p<.001) than PT generated by the identical muscle group on the ND side. DOM FLEX, EXT, AB, AD, IR, & HD ECC PT production is greater (p<.001) than PT generated by the identical muscle group on the ND side. These data show that, for certain muscle groups & modes of contraction, the DOM shoulder of the college-aged male is stronger than the ND.
