Six male industrial workers performed 42 variations of lifting, lowering, pushing, pulling, and carrying tasks. Lifting boxes without handles produced consistent decreases (median, 16%) in maximum acceptable weights when compared with lifting boxes with handles. Lifting with extended horizontal reach (approximately 48 cm) produced consistent decreases (median, 48%) in maximum acceptable weights when compared with lifting close to the body (approximately 17 cm). No significant heart rate or oxygen consumption differences occurred in either of these variables. No significant differences in maximum acceptable weight of carry were observed among box sizes; however, the maximum acceptable force of pulling was lower for longer (15.2 m) pulling tasks. The maximum acceptable weight for combination tasks was similar to that of the limiting component.<\/jats:p>","DOI":"10.1177\/001872089303500110","type":"journal-article","created":{"date-parts":[[2017,7,20]],"date-time":"2017-07-20T06:50:13Z","timestamp":1500533413000},"page":"175-186","source":"Crossref","is-referenced-by-count":73,"title":["Further Studies of Psychophysically Determined Maximum Acceptable Weights and Forces"],"prefix":"10.1177","volume":"35","author":[{"given":"Vincent M.","family":"Ciriello","sequence":"first","affiliation":[{"name":"Liberty Mutual Insurance Company, Hopkinton, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stover H.","family":"Snook","sequence":"additional","affiliation":[{"name":"Liberty Mutual Insurance Company, Hopkinton, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gareth J.","family":"Hughes","sequence":"additional","affiliation":[{"name":"Liberty Mutual Insurance Company, Hopkinton, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1993,3,1]]},"reference":[{"key":"atypb1","volume-title":"Textbook of work physiology.","author":"Astrand, P.
