The effect of size and fabric weight of protective coveralls on range of gross body motions.
Am Ind Hyg Assoc J 1995 Apr; 56(4):333-340
The effects of garment size and fabric weight on range of motion (ROM) were evaluated. Ten male subjects performed a series of 12 gross body movements while wearing each of nine similarly styled overalls which were constructed from three different weights of fabric and were undersized, appropriately sized, or oversized. Fabrics were all woven, and included a 4.25 ounce/square yard (oz/yd2) 65/35 poly/cotton, a 7.25oz/yd2 50/50 poly/cotton, and a 10.0oz/yd2 50/50 poly/cotton. Control trial conditions consisted of athletic shorts, briefs, socks, and athletic shoes. A two arm manual goniometer was used to measure ROM. Garment size had a significant effect on all movements except for trunk lateral flexion and shoulder extension. Undersized garments reduced the mean ROM by up to 24% in the case of hip flexion when compared with control ROM. Fabric weight had a smaller effect on ROM than garment size. The effect of fabric weight was significant for elbow flexion, shoulder horizontal flexion, and hip flexion. The authors conclude that undersized garments can drastically reduce movement capability.
