[Runners with back pain: to run or not to run?]. / Coureurs souffrant de maux de dos: courir ou ne pas courir?

ABSTRACT

We evaluated the perceived impact of physical activity on back pain in runners. Information from 777 runners participating in a half marathon was obtained with a questionnaire about basic data, features of the weekly training and the relationship between running activity and back pain. Half the runners (54.1%) reported a history of back pain. Among them, almost twice as many reported an improvement (49%) than a worsening (27%) of pain with running. No significant associations were found between perceived impact of running on back pain and other factors. In our study favorable effects were much more frequent than unfavorable ones. Further studies are needed to better understand these effects.
