The influence of a gymnastic pause upon recovery following post office work.

The influence of a gymnastic pause and of a passive pause after work was compared in the Post-Cheque Office in Brussels. A group practising some light gymnastic movements and a control group taking a passive rest, each composed of 40 subjects, were examined by a test battery consisting of the flicker fusion frequency test, Wechsler's digit symbol test, a hand dynamometer test, and Pieron's tremor test. The tests were carried out before and after the pause. The results were interpreted to mean that hand steadiness improved, that general fatigue and fatigue of the eyes diminished, that the girls worked faster, and that muscular strength was greater after the gymnastic pause than after the passive pause.
