[Work capacity of the operators of chemical industry and its effect on motor activity]. / Rabotosposobnost operatorov khimicheskikh proizvodstv i eë zavisimost ot obëma dvigatelnoi aktivnosti.

Motor activity, energy metabolism, work productivity, functioning and regulation of cardiovascular system were examined in machine operators working at 2 chemical enterprises. The energy loss within the shift appeared to vary from 800 to 1200 kcal, that within the day--from 2,500 to 2,900 kcal. The examinees demonstrate lack of physical training that affects the functioning of cardiovascular system. However, the study found no correlation between the Physical State Index and the work productivity. The elderly operators show higher work productivity associated with more noticeable lack of physical training. The authors conclude also that daily amount of physical load should be considered in evaluation of low physical training impact.
