Abstract

A laboratory study was conducted to determine static lifting strengths on 13 males and 12 females from 18 to 28 years of age. Using the strength monitor, the average strength and peak strength were measured in four different postures: standing, floor-sitting, and lying-on-the-stomach with and without elbow support. The statistical results indicated significant differences among postures and between sexes. No significant difference was found between sitting and lying on the stomach with support. However, female lifting strengths ranged from 49% to 55% of male strengths in all postures. This study is a further step in establishing personnel criteria and lifting-strength estimation for selecting entry employees in awkward lifting jobs such as in maintenance, coal mines, and aircraft assembly. The regression model indicates that load ratios can be established in terms of standard load tests for personnel evaluations.
