Abstract
The health effect of a muscle strenght and endurance training programme on shoulder/neck disorders in cashier checkout workers was investigated. 29 checkout workers from two large retail supermarkets participated in 30 training sessions during a 15-week training programme. In comparison to a control group (n=24) without training, the trained group showed an increase in muscle strength and endurance. Perceived exertion in a dynamic and a static endurance test were significantly lowered in the training group compared with the control group. The trained group reported that checkout work felt less tiring as an effect of the training programme. Improvement of neck complaints was more pronounced in the training group than in the control group. This effect, however, may be ascribed to a pre-training difference in the level of complaints between the two groups. No significant training effect on shoulder complaints could be shown.
