English abstract<\/strong><\/p>\n

The aims of this project were: 1) to provide data regarding the physical abilities of Icelandic male handball players, by using 9+ screening test. 2) to register prevalence of overuse problems in the knee, low-back and dominant shoulder and to investigate if 9+ screening test score could predict for overuse problems. 3) to record the players training load during pre-season, to register prevalence of overuse problems in the knee, low back and dominant shoulder and assess the possible association between the training volume and overuse problems.<\/p>\n

Several physical factors from players from 13 handball teams were tested using a 9+ screening test with players earning score according to their performance. The players answered the Oslo Sport Trauma Research Centre (OSTRC) overuse questionnaire regarding overuse problems in the knee, low-back and shoulder during one competitive season. During a 6-week pre-season, players from 10 teams answered the OSTRC overuse questionnaire weekly. The coaches recorded their teams training volume and training types.<\/p>\n

The main results were that age-related differences were observed. Junior players displayed lower scores than senior players in tests measuring abdominal strength and stability, but higher in tests measuring trunk and shoulder mobility. About 30% of the players reported overuse problems (OP) in the knee, low-back or shoulder at any given time during the research period. Ten percent reported substantial overuse problems (SOP), affecting their performance and\/or participation. No association was found between overuse problems and the 9+ screening test score. The prevalence of OP and SOP was higher in the shoulder in the pre-season compared to the competitive season, but lower in SOP in the low-back. The knees were most susceptible for OP during the pre-season, with running exercises and shooting practice as the main risk factors. Jumping was associated with OP in the low-back.<\/p>\n
