The Relationship between the Bunkie-Test and Physical Performance in Rugby Union Players

It is suggested that restrictions in the fascia along the kinetic chains could inhibit muscle function and therefore influence movement patterns, such as those required by skilled rugby players. The Bunkie-test has been proposed as a tool to identify fascia restrictions in five kinetic chains. The purpose of this study was to use the isometric Bunkie-test to determine its relationship with performance in selected physical tests (agility, speed, explosive power, and muscle endurance) in rugby union players. The participants (n = 121) were rugby union players from three academies. Results indicated significant relationships (p < 0.05) between performance in the Bunkie-test and the physical tests. Players who performed better on the Bunkie-test achieved better results in the physical tests. The Bunkie-test might be a tool for coaches, trainers and therapists to identify weaknesses and imbalances in the kinetic chains of players. Addressing these problems could lead to improvements in sport performance, as well as assessing readiness of players to return to play after injuries.
