The static muscular strength of the back extensors, arm flexors and hand grip were measured on industrial workers (463 men and 139 women) involved in physically demanding jobs. No significant differences in strength were found among workers on different jobs. However, strength differences were evident with respect to age and sex; women were about 60 percent as strong as men, and men below 31 years of age were stronger than men above this age.
对从事体力要求较高工作的产业工人（463名男性和139名女性）的背部伸肌、手臂屈肌和握力的静态肌肉力量进行了测量。不同工作的工人之间未发现力量有显著差异。然而，在年龄和性别方面力量差异明显；女性的力量约为男性的60%，31岁以下的男性比这个年龄以上的男性更强壮。
