Therapeutic climbing currently has high popularity in treating glenohumeral instability. Therefore, the aim of this study was to quantify the muscular activation of the middle and upper trapezius (MT, UT) and serratus anterior (SA) of four quasi-static climbing positions (Jug, Undercling, Sidepull with external and with internal rotation) of 15 participants. Additionally, the effect of releasing one hand from the support handle on the muscular activation was analysed. The maximum in both handed conditions were 23% (MT), 9% (UP) and 7% (SA). Releasing one hand significantly increased the muscle activation level, which was especially evident for the Sidepull with external rotation (MT, SA) and internal rotation (UT). The analysed positions elicited similar muscular activation levels as common shoulder rehabilitation exercises in healthy participants.
