Background: To perform general warm-up prior to athletics is widely recognized and has adocumented effect on performance. Lower extremity injuries are commonly occurring forsoccer, handball, volleyball, and floorball players. Injury prevention exercises decreases therisk for musculoskeletal injuries, supposing good compliance exists. Whether injurypreventive exercises may increase performance is to this day unclear. Aim: The aim of the study was to compare performance measured in vertical jump height ofathletes after injury preventive exercises and general warm-up. Methods: Experimental study with a cross-sectional design. 17 active soccer, handball,volleyball, and floorball players between 20-32 years were recruited through conveniencesampling. Data was collected occurred by measurement of maximal vertical height done bycountermovement jump (CMJ) on an electronic contact mat. Results: No statistically significant differences regarding vertical jump height wereidentified when comparing injury preventive exercises and general warm-up. Conclusion: The result from the study suggests that male soccer and handball players maybenefit from performing injury prevention exercises instead of general warm-up prior tomaximal vertical jumps due to the decreased risk for injury while the effects of general warmup still emerges. Further research within the subject is necessary to investigate whetherinjury prevention exercises may replace general warm-up prior to more complexperformances such as sports. Further research on others than male handball and soccerplayers should be conducted.
