The main research goal of the study was to identify the type and severity of injuries and the risk factors of injury among Croatian rugby players. The sample consisted of 122 players who agreed to be part of the study and 100 of them who, in addition to the entry questionnaire, completed weekly reports related to injuries and pain. The sample comprised the entire available population of Croatian rugby players in the 2014/15 spring season. To modified previously validated questionnaire was applied and players were asked about injury occurence once a week. To determine the type and severity of the injury and the risk factors of injury among Croatian rugby players frequenices and percentages were calculated. In order to determine the associations between predictors and outcome (injury prevalence and occurence), logistic regression and Chi square were calculated depending on type of predictor variables. The incidence of injury in the analyzed sample was 99.68 injuries per 1000 match-hours and 5.29 injuries per 1000 training-hours. Several risk factors for injury occurence were identified, including: body mass, injury during the pre-season, higher level matches and pain occurence In particular, a higher risk of injury was observed for heavier players (OR: 1.02 95% CI: 1.01-1.04), players who had a pre-season injury (OR: 0.42 95% CI: 0. 23-0.75), when playing higher level matches (OR: 1.59 95% CI: 1.29-1.96) and players who reported pain (OR: 7.44 95% CI: 4, 17 to 13.25). In addition, the data showed that the type of footwear should be considered as a certain risk factor, as injured players were more likely to wear blade studded boots. In order to reduce injuries, it is necessary to monitor players injuries during the preparation part of the season, as well as to regularly evidence eventual occurence of pain throughout the season. The shoulder and knee were the most injured body locations, and therefore preventive exercise programs are neccesary.
