Bank female employees, aged from 18 to 55, were examined in order to characterize some changes in the nervous-psychic capacity for work in age aspect. The following methods were used: inquiry for the subjective assessment of the strain and fatigue during work, DAM--a test characterizing the activity, disposition and mood, level of neurotism according to Ajsenk, time of single visual-motor reaction and reaction of choice. Some age changes in the subjective assessment of fatigue, disposition, and activity were established. The age changes in psychomotor sphere were enhanced under the effect of work loading. Among the age group 51-55, the subjective assessment of fatigue, disposition and activity were more favourable, not corresponding to the clearly manifested age changes in psychomotor sphere. Prophylactic measures, aiming at the optimization of the work of bank female workers, are elaborated on the base of the examinations carried out.

Effects of muscle fatigue on force coordination and task performance of various manipulation tasks are explored. Grip force (GF; normal force component acting at the digits-object contact area) and load force (LF; tangential component that lifts and holds objects) were recorded prior to and after fatiguing the distal (DAM; i.e., GF producing) and proximal arm muscles (PAM; LF producing). Results reveal a deterioration of GF scaling (i.e., averaged GF-LF ratio), GF-LF coupling (their correlation), and task performance (ability to exert a prescribed LF pattern) associated with DAM, but not PAM fatigue. Deteriorated force coordination clearly increases the likelihood of dropping an object; however, the observed selective effects of DAM and PAM fatigue represent a novel finding deserving of further research.
