Prevalence of injury in ultra trail running

Abstract

PurposeThe purpose of the study was to find the rate of musculoskeletal injuries in ultra-trail runners, investigate the most sensitive anatomical areas, and discover associated predicting factors to aid in the effective prevention and rapid rehabilitation of trail running injuries.MethodsForty ultra trail runners responded to an epidemiological questionnaire.ResultsAt least one running injury was reported by 90% of the sample, with a total of 135 injuries were reported (111 overuse injuries, 24 appeared during competing). Lower back pain was the most common source of injury (42.5%). Running in the mountains (<i>p</i> = 0.0004) and following a personalized training schedule (<i>p</i> = 0.0995) were found to be protective factors. Runners involved in physical labor are associated with more injuries (<i>p</i> = 0.058). Higher-level runners are associated with more injuries than lower-level cohorts (<i>p</i> = 0.067), with symptoms most commonly arising in the lower back (<i>p</i> = 0.091), hip joint (<i>p</i> = 0.083), and the plantar surface of the foot (<i>p</i> = 0.054). Experienced runners (> 6 years) are at greater risk of developing injuries (<i>p</i> = 0.001), especially in the lower back (<i>p</i> = 0.012), tibia (<i>p</i> = 0.049), and the plantar surface of the foot (<i>p</i> = 0 .028). Double training sessions could cause hip joint injury (<i>p</i> = 0.060).ConclusionsIn order to avoid injury, it is recommended to train mostly on mountain trails and have a training program designed by professionals.
