Zusammenfassung (Englisch)

The aim of the study was to quantify the activation of arm and shoulder muscles during a static therapeutic climbing exercise

and to investigate the possibility of altering the muscle activation through arm position (Jug, Undercling, Sidepull internal

rotated, Sidepull external rotated), hand support (one-handed, double-handed) and wall inclination (0, 12).

Electromyographic (EMG) activity of 14 healthy, climbing unexperienced males for the right m. biceps brachii (BB),

m. serratus anterior (SA), m. upper, middle and lower trapezius (UT, MT, LT) showed mainly low to moderate EMG

activation levels (BB: 4.140.1% maximum voluntary isometric contraction (MVIC), SA: 4.524.5% MVIC, UT: 1.3

28.0% MVIC, MT: 8.647.1% MVIC, LT: 3.847.3% MVIC). Significant differences occurred between the four arm

positions for the UT and LT. The one-handed support revealed significant higher muscle activation than the doublehanded

support in every condition except for SA in Undercling arm position at 12 wall inclination. Increasing the wall

inclination (from 0 to 12 overhang) led to a significant increase in muscle activation in nearly every exercise variation

and muscle. These findings suggest that arm position, hand support and wall inclination are appropriate possibilities of

altering muscle activation patterns in therapeutic climbing.
