N2 - Support personnel tasks of brattice construction and rock-dust bag carrying were simulated in a laboratory setting. Two different seam heights (1.07 m and 1.37 m) and two different postures (kneeling and stooping) were studied for stooping construction. For bag carrying, a handle was either used or not. All dependent measures, energy expenditure, heart rate and Borg's rating of perceived exertion, indicated that the kneeling posture was preferred over stooping. Similarly, the use of handles reduced the difficulty of bag carrying.
