Introduction: Balance is a complicated term which includes a static, dynamic and functional part. These parts have, during a long period of time, been included into the existing training programs through several different balance exercises, which aim to prevent sports injuries mostly focused on the knee and ankle. In floorball these injuries are common and a sports injury prevention program is required. Purpose: The purpose is to explain the balance term and relate it to injury prevention training and the existing theories. A second purpose is to see whether five weeks of balance training increases the balance ability in female floorball players and thereby increase the test values in the two tests. Method: Twenty female floorball players participated in the study and were divided into a training group and a control group. They performed a Star excursion balance test (SEBT) and a Multiple single leg hop stabilization test (MSLHST) before and after a five week training period, containing exercises of balance. Results: The training group showed improvement after the training period, however only one significant result was found. The control group showed no improvements, rather the opposite in some parts of the tests. Conclusions: The results indicate that there could be an injury preventive effect coming from balance training, but the training program and the tests have to be customized to suit the training group. Nevertheless, balance training should be recommended as a compliment to the ordinary training session.
