Common occupational health problems, especially low back pain, are associated with physical demands of work, like lifting heavy weights. The study examined a multidimensional methodological approach (BASE) to reduce physical stresses in a logistic company in three stages: (1) theoretical background and implementation of the program, (2) evaluation of outcome-effects of a box lifting training (10 weeks) and (3) learning and lasting effects of workers' knowledge and behaviour with regard to ergonomic box lifting. Video analysis and questionnaires were used for breakdown analysis. Stage (2) and (3) collected intervention effects with a controlled preaEuropost test design (N = 41 males; 37.8 +/- 10.8 y.). The breakdown analysis revealed low back pain (65 \%) as a result of repeated manual lifting processes. Participants of the intervention showed a more ergonomic movement initiated by a more functional cognitive representation in long term memory. We suggest that especially this group of employees, with little motivation to participate in health promotion, benefit from the whole methodological approach of the BASE-program.
