Ultimate frisbee is a team sport where players mainly use their dominant arm for throwing the frisbee. Little is known about possible functional adaptations to this unilateral strain and the purpose of this study was to investigate related shoulder rotation strength and range of motion (ROM) in elite ultimate players. Concentric external (ER) and internal (IR) isokinetic (60°/s) shoulder rotation torque and passive glenohumeral (GH) ROM was tested in 15 male subjects (27.5 ± 5.5 yrs). Work during ER was higher on the dominant side (8.4 ± 8.4 %; p<.01). IR ROM and total ROM was smaller on the dominant side (21 ± 18 %; p<.01 or 5 ± 9 %; p<.05). This indicates similar adaptation patterns of GH mobility compared to other overhead sports, however, differing results regarding shoulder rotation strength.
