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.
对两家化工企业的机器操作员的运动活动、能量代谢、工作效率以及心血管系统的功能和调节进行了检查。轮班期间的能量损失似乎在800至1200千卡之间，一天内的能量损失在2500至2900千卡之间。受检者表现出缺乏体育锻炼，这影响了心血管系统的功能。然而，研究发现身体状况指数与工作效率之间没有关联。年长的操作员工作效率较高，但缺乏体育锻炼的情况更明显。作者还得出结论，在评估缺乏体育锻炼的影响时应考虑每日的体力负荷量。
