The objectives of this study were to determine whether significant differences existed between bicyclists and noncyclists in cervical range of motion (ROM), the incidence and intensity of cervical pain, and whether there was a correlation between cervical ROM and the intensity of cervical pain. This study included two age matched groups of subjects; eight bicyclists (bicycling at least 5 hr/wk) and eight noncyclists (bicycling less than 1 hr/wk). Six cervical ROM measurements were taken from each subject using a cervical range of motion device. Pain incidence and intensity were determined by administering a survey to each subject. The data was analyzed and the results indicated a significant (p < .05) decrease in mean cervical flexion in bicyclists (41.8) as compared to noncyclists (56.8). No significant difference was noted in any of the other five cervical ROM measurements. In addition, bicyclists and noncyclists failed to demonstrate significant differences in pain incidence or intensity (p < .05). Finally, there was no significant correlation between cervical ROM and cervical pain intensity. These results indicate that cyclists appear to develop selective shortening of specific cervical musculature (extensors) . This should be considered in prevention and treatment of cervical injuries in cycling.
