[Effect of long-term moderately hard and hard physical work on the psychomotor efficiency and mental work capacity (II.)].

23 women, aged 19--24, of average physical efficiency, were examined. The following aspects were taken into account: an influence of long-lasting cyclic physical work on bicycle ergometer on the results obtained during the visual and auditory reaction time, the task performed with different speed using the test of visual and motorial coordination and Piórkowski's Test, as well as work efficiency in Pauli's test and learning and reproduction of nonsensical syllables. Long-lasting physical work resulted in a significant prolongation of the visual reaction time and increased number of mistakes in case of a task performed with maximum speed using the test of visual and motorial coordination. Negative but weak effects of physical effort were observed in the results of auditory reaction time and tasks checking the mental work efficiency. In the initial stage of the experiment (the early part) in some tasks a positive effect of physical effort was observed.
