Interfering effects of the task demands of grip force and mental processing on isometric shoulder strength and muscle activity / Christopher W. Macdonell and Peter J. Keir

The purpose of this study was to evaluate the effects of a concurrent sub-maximal grip and mental load no upper extremity muscle activity and siometric shoulder exertions at three frontal planes. To achieve this, the study evaluated maximum shoulder exertions at three shoulder angles of flexion and abduction in all possible combinations with and without shouder angles of flexion and abduction in all possible combinaitons with and without using a 30% relative grip forece exertion and the Stroop test
