The Prevalence of Lower Extremity Injuries in Running and Associated Risk Factors: A Systematic Review

Abstract

Introduction: Running is an extremely popular pastime and competitive sport. There is a general consensus that runners present a high incidence of injury. This study aims to discover the prevalence of injury to the lower extremity among runners and any associated risk factors which correlate with the development of lower extremity injuries. Methods: An inclusion and exclusion criteria were used to screen search results. From an original 184 search results, 24 research papers were selected for the final study. The PRISMA checklist was adhered to in the research process. EndnoteX9 was used to filter through all search results and to achieve the final study selections, in line with the appropriate criteria. Results: Overall, a mean incidence of 37% was displayed for running related injuries to the lower extremity. Females displayed a greater mean incidence of injury than males, 39.7% vs 34.3%. Injury prevalence presented greatest at the knee region (24.3%), but this differed when results were split into male and females. Females presented the greatest prevalence of injury at the calf/lower leg, whilst males presented greatest incidence of injury at the hip/pelvis/upper leg region. Risk factors for developing injury which were identified throughout the research included; having 3 times per week. Conclusion: This systematic review is in agreement with the literature which has repeatedly illustrated that female runners present a greater incidence of injury than male runners.
