Incidence and determinants of lower extremity running injuries in long distance runners: a systematic review

The search in PubMed-Medline produced a group of abstracts which were screened using the following criteria: The subject of the study was running injuries to the lower extremities occurring in long distance runners. We included only studies where subjects ran >= 5 km per training or race, or both. The runners were recreational or competitive runners, but not belonged to the elite group (which presumably can rely on a better medical support). The study described epidemiology (prevalence, incidence) or aetiology (determinants) of lower extremity running injuries, or both. The study included a study population of at least 10 individuals (cross sectional studies, prospective cohort studies, retrospective cohort studies, case control studies, case series and clinical trials). The study was written in English, Dutch, German, French, Spanish, Italian, Danish, Norwegian, Swedish, Icelandic or Indonesian.
