The protection of an athlete's health and preventing injuries and illnesses in sport are top priorities for the IOC and its Medical Commission. The IOC therefore partners with selected research centres around the world and supports research in the field of sports medicine. This has enabled the IOC to develop an international network of expert scientists and clinicians in sports injury and disease prevention research. The IOC wants to promote injury and disease prevention and the improvement of physical health of the athlete by: (1) establishing long-term research programmes on injury and disease prevention (including studies on basic epidemiology, risk factors, injury mechanisms and intervention), (2) fostering collaborative relationships with individuals, institutions and organisations to improve athletes' health, (3) implementing and collaborating with applied, ongoing and novel research and development within the framework and long-term strategy of the IOC and (4) setting up knowledge translation mechanisms to share scientific research results with the field throughout the Olympic Movement and sports community and converting these results into concrete actions to protect the health of the athletes. In 2009, the IOC also identified four research centres that had an established track record in research, educational and clinical activities to achieve these ambitions: (1) the Australian Centre for Research into Injury in Sport and its Prevention (ACRISP), Australia; (2) the Sport Injury Prevention Research Centre (SIPRC), Canada; (3) the Clinical Sport and Exercise Medicine Research (CSEM), South Africa and (4) the Oslo Sports Trauma Research Center (OSTRC), Norway. This paper highlights the work carried out by these four IOC Centres of Excellence over the past 6 years and their contribution to the world of sports medicine.
This study investigated the tackling technique of high-performance, collision-sport athletes and documented the relationships between tackling technique and playing experience, playing level, game-specific tackling performance, and injury in these athletes. Twenty-two national rugby league (NRL) and 17 state-based rugby league (SRL) players underwent a standardized one-on-one tackling drill in a 10 m grid. Video footage was taken from the rear, side, and front of the defending player. Tackling technique was assessed using standardized technical criteria. A large difference (ES = 1.53, p <0.05) was detected between playing groups for tackling technique, with NRL players having better tackling technique than SRL players. Players who had at least 150 NRL matches experience had a significantly greater (ES = 1.1–1.6, p <0.05) tackling technique than players who had played up to 49 NRL matches, 50–99 NRL matches, or 100–149 NRL matches. Significant relationships (p <0.05) were detected between tackling technique and the proportion of tackles missed each game (r = −0.74) and the proportion of dominant tackles effected each game (r = 0.78). There was no relationship between tackling technique and the incidence of tackling injuries. The results of this study demonstrate that playing level and playing experience influence tackling technique in high-performance, collision sport athletes, with greater playing experience and playing level associated with greater tackling technique. Furthermore, significant relationships were detected between tackling technique and the proportion of tackles missed each game (negative) and the proportion of dominant tackles effected each game (positive). Identifying the factors that limit tackling proficiency may assist playing performance, but may have minimal effect on injury prevention in high-performance, collision-sport athletes.
