Cause of the rising costs for the treatment of chronically low back pain, the develop- ment of evidence based and standardised therapeutically strategies is in the focus. The focus is now days on high quality in preventive and rehabilitee strategies.
Until now there are not many studies available about the physical effects of therapeu- tically measures of training who qualify the influence of the medium water concering conditional and coordinative parameters in an objective way.
The existing study follows that for the questioning if and how for active forms of train- ing in water influence the maximal strengths and the neuromuscular function of the trunk muscles, as well as reducing the low back pain.
As competition of the therapeutically treatment spectrum in the active rehabilitation of chronically back pain were proven new aqua training devices for strengthening of the trunk muscles.
