[The physiologic effect of lifting weights from the floor and working surface at different rates].

The article provides data on the physiological value workload in lifting weights from different surface levels (the floor and working surface at the level of 0.7 m from the floor), at different rates and at the distance of 0.7 m. The results of the study proved that, in case of manual lifting of weights, the rate and the surface level are the most important factors accounting for the degree and the nature of the physiological reactions, e. i the physiological value of the workload. Manual lifting of weights from the working surface is marked by a lower physiological value of workload and higher efficiency. This should be taken into account in manual labour planning, workload and labour intensity evaluation, labour conditions and recreation improvement.
