Cardiovascular, hormone, and lipid responses to stress induced by virtual crane handling.

Objectives: The aim of the study was to test whether a mixed-mock-up-simulator (MMU-simulator) is suitable for on-the-job training by measuring stress reactions induced by handling a crane in a virtual environment in subjects not experienced in crane operation.

Materials And Methods: A MMU-simulator in a virtual environment was developed. Twenty three individuals were randomly divided into Group 1 (n = 13) and Group 2 (n = 10).
