The 20 members of the Western Australian fast bowling development squad (mean age, 17.9 years), who had previously undergone routine computed tomography (CT) and magnetic resonance imaging (MRI) scans to detect the presence of bony and intervertebral disk abnormalities, acted as subjects for this study. While these radiologic data were being analyzed, these players were filmed both laterally (200 Hz) and from directly above (100 Hz) as their front foot impacted a force platform during the delivery stride of the fast bowling action. On a subsequent trial, kinetic data from the platform were recorded when their back foot impacted the force platform. In addition, these bowlers performed selected physical capacity tests. The occurrence of abnormal radiologic data were then used to group the bowlers (group 1: no abnormal radiologic features from CT or MRI scans; group 2: disk degeneration or bulging on MRI scan; group 3: spondylolysis, spondylolisthesis, or pedicle sclerosis). A Mann‐Whitney U‐rank test was then used to identify any significant differences (p<0.05) between the groups for all dependent variables. Pars interarticularis and intervertebral disk abnormalities were commonly identified in this sample of fast bowlers (55 and 65%, respectively) and all players who had experienced back pain had evidence of a radiologic abnormality. No player with a normal diagnosis complained of pain. The appearance of these features was attributed to a combination of factors rather than a single cause. Bowlers who recorded poorer hamstring or low back flexibility predisposed themselves to a disk abnormality, whereas those who delivered the ball from a high release height relative to their standing height and players who had bowled over several seasons during their growth period were predisposed to a bony abnormality. Furthermore, bowlers who used a technique that combined a front‐on back foot placement and a side‐on shoulder alignment were more likely to present abnormal radiologic features in the lumbar spine.
