Exercise-Related Leg Pain in Female Collegiate Athletes

Abstract

Background Exercise-related leg pain is a common complaint among athletes, but there is little evidence regarding risk factors for this condition in female collegiate athletes. Purpose To examine prospectively the effect of selected extrinsic and intrinsic factors on the development of exercise-related leg pain in female collegiate athletes. Study Design Cohort study; Level of evidence, 2. Methods Subjects were 76 female collegiate athletes participating in fall season sports, including cross-country running, field hockey, soccer, and volleyball. Athletes were seen for a preseason examination that included measures of height, weight, foot pronation, and calf muscle length as well as a questionnaire for disordered eating behaviors. Body mass index was calculated from height and weight (kg/m2). Those athletes who developed exercise-related leg pain during the season were seen for followup. All athletes who developed the condition and a matched group without such leg pain underwent bone mineral density and body composition testing. Statistical analyses of differences and relationships were conducted. Results Of the 76 athletes, 58 (76%) reported a history of exercise-related leg pain, and 20 (26%) reported occurrence of exercise-related leg pain during the season. A history of this condition was strongly associated with its occurrence during the season (odds ratio, 13.2). Exercise-related leg pain was most common among field hockey and cross-country athletes and least common among soccer players. There were no differences between athletes with and without such leg pain regarding age, muscle length, self-reported eating behaviors, body mass index, menstrual function, or bone mineral density. Athletes with exerciserelated leg pain had significantly (P < .05) greater navicular drop compared with those without. Conclusion Exercise-related leg pain was common among this group of female athletes. The results suggest that there are certain factors, including foot pronation, sport, and a history of this condition, that are associated with an increased risk of exerciserelated leg pain.
