PURPOSE/ BACKGROUND: Exercise-related leg pain (ERLP) is a common problem in runners. The purposes of this study were to 1) report ERLP occurrence among adult community runners; 2) determine ERLP impact on daily activities; and 3) determine if there is a relationship between ERLP occurrence and selected potential risk factors including sex, age, years of running, ERLP history, body mass index (BMI), orthotic use, menstrual function, and training variables. METHODS: Community runners registered for a local race were invited to complete a questionnaire including demographics and potential risk factors. Analyses of differences (t-test) and relationships (Chi-square) were conducted and relative risk (RR) values were calculated. RESULTS: 225 registered runners (105 male, 120 female) participated; 63.6% reported ERLP history, and 35.1% reported ERLP in the 3 months preceding the race with bilateral medial ERLP as the most common presentation. Of the 79 runners who experienced ERLP during the 3 months preceding the race, ERLP caused 41.8% to reduce their running and interfered with walking or stair climbing in < 10%. Chi square analyses showed no significant association of sex, menstrual function, orthotic use, or BMI with ERLP occurrence. Significant associations were observed between ERLP history and ERLP occurrence in the previous year (RR=3.39; 2.54-4.52 95% CI), and between ERLP in the 3 months preceding the race and both years running and training mileage. Greater ERLP occurrence was observed in runners with less than 3 years experience (RR = 1.53; 1.08-2.17 95% CI) and runners who ran fewer than 15 miles/week (RR = 1.47; 1.04-2.08 95% CI). Those runners with < 3 years running experience and a race pace of 9 min/mile or > were at greater risk for ERLP when compared to other participants (RR=1.53; 1.07-2.18 95% CI). CONCLUSION: Interfering ERLP was common among this group of community runners. Risk factors included ERLP history, training mileage < 15 miles/week, and < 3 years running experience. Further investigation is warranted to identify factors which may increase a community runner's risk of developing ERLP. LEVEL OF EVIDENCE: 2b.
