Validity of the baltimore therapeutic equipment work simulator in the measurement of lifting endurance in healthy men.

OBJECTIVE: To examine the criterion validity of the Baltimore Therapeutic Equipment (BTE) work simulator by comparing endurance time, oxygen uptake (VO2), and heart rate measured during real and simulated lifting tasks and to derive a regression equation for predicting actual lifting endurance from measurements on the work simulator. METHOD: Twenty healthy male volunteers repetitively lifted and lowered a load of 40 lb using the BTE work …
