摘要

There are more than 16 million runners in the United States who train a minimum 100 days per year. Runners can be separated into the following three categories on the basis of training frequency: (a) core participants (> 50 runs/yr), (b) frequent runners (> 100 runs/ yr), and (c) core runners (> 224 runs/yr). The core runner category includes most competitive high school and collegiate runners in the United States as well as recreational runners training for distances ranging from 5 km to half-marathons (13.1 miles). In addition to the high running frequency per year, the core runner averages 31 miles per week. Given the repeated stresses and high impact loads of running, up to 46 % of runners suffer a running-related injury each year. Further, lower extremity stress fractures (LESFs) are reported to account for up to 20% of all injuries in athletes, with runners and track athletes experiencing the greatest incidence. Among runners, the tibia is highly susceptible to fracture, accounting for up to 55% of all LESFs. Combining the high incidence of LESFs in runners with recovery typically requiring up to 8 weeks, participation in training and competition can be greatly disrupted.participation in training and competition can be greatly disrupted.
