Van Pletzen and Venter (2012) showed that there was a correlation between the results of the Bunkie test (which measures fascia restrictions in five kinetic chains) and tests which measured rugby players' physical condition: vertical jump performance (p < 0.05; r = 0.24), repeated sprint ability (p < 0.05; r = 0.22), Illinois agility (p < 0.05; r = -0.23), 10 m sprint performance (p < 0.05; r = 0.24), 40 m sprint performance (p < 0.05; r = -0.25) and Max pull-ups (p < 0.05; r = 0.27). Players who showed higher levels of strength in the core muscles and therefore obtained better results in the Bunkie test also performed better in the various physical tests.
