摘要: The purpose of this study was to compare the effect two different positions shoulder internal rotation (IR) and external (ER) on isokinetic concentric eccentric peak torque as well conventional dynamic ratios. Nineteen athletes (Eigth judo eleven tennis players), (20.3 ± 5.2 yrs) performed 5 maximal unilateral IR ER repetitions at 60 � /s 120 /s. subjects also 3 respectively. tests were in seated positions: 1) with abducted scapular plane, 2) flexed saggital plane. S houlder control ratio (DCR) assessed. plane position showed significa ntly (p < 0.05) greater (PT) values than during both speeds. However, PT significantly Additionally, DCR g reater for position. These results sug gest that test is an important variable i sokinetic testing.
