Swimming, biking, and running each have a host of overuse injuries that can occur as a result of overtraining. High running mileage, a history of previous injury, inadequate warm up or cool down, and an increase in the years of triathlon experience are a few of the factors that have been linked to triathlon overuse injuries. Early identification of overtraining symptoms and a corresponding reallocation of balance between each discipline, perhaps with an emphasis on increasing swimming, may help prevent many overuse injuries. © 2012 Lippincott Williams & Wilkins, Inc.
