      <subfield code="a">The purpose of this paper was to differentiate the physiological effects of carrying different weights on children by simultaneus measurement of expired air, heart rate and blood pressure. It was hoped that the finding of this paper would help to produce guidelines on approved school bag weight</subfield>
