• Description:
  Twelve male subjects with mining experience participated in a U.S. Bureau of Mines investigation of the acceptable weights and physiological stresses while lifting a crib block. The independent variables were posture, symmetry, and lifting height. The dependent variables were the maximum acceptable weight of lift (MAWL), heart rate (HR), absolute and normalized oxygen utilization (AVO2 and NVO2), ventilation volume (Ve), and respiratory exchange ratio (R). HR, NVO2, AVO2, and Ve were all significantly higher in the stooped posture than in the kneeling posture, and R was higher in restricted postures than in the unrestricted posture. NVO2, AVO2, and Ve were higher when lifting to a higher shelf. MAWL was a function of posture, symmetry, and lifting height. The data indicate that the weight of crib blocks is often above acceptable weight limits for the tasks tested. [Description provided by NIOSH]
