The working capacity of the older employee.

Abstract

Measurements of working capacity in the factory should include tests of aerobic power, obesity, and strength. Aerobic power shows a progressive decline throughout the span of working life, and by the age of 60 many men and almost all women seem unlikely to sustain an eight-hour work load at three times the resting level of energy expenditure without fatigue. Workers over the age of 40 carry a substantial burden of body fat, and diminishing muscle strength also increases their liability to fatigue. The relation of these findings to productivity is discussed, and the possible improvement of working capacity through use of an appropriate training regime is set at 15% to 20%. Motivation to increased activity is considered, and is suggested to be a justifiable charge upon company finances.
