[A method of evaluating physical exertion during work based on the assessment of work capacity].

A method of calculating the synthetic index of effort capability, based on results of submaximal effort test, has been presented. Examinations of people working at 4 workstations demonstrated that the reduced effort capability after work is proportional to work energetic expenditure. The usefulness of work fatigue analysis has been indicated, as its magnitude, when accompanied by evaluation of effort capability changes, points to static load as an additional disadvantageous factor.
