Background. Athletics is one of the sports modalities with the greatest growth in the number of federative licenses in our country. In the last five years, the use of footwear with Advanced Footwear Technology (AFT) has become widespread in order to increase athletic performance.
Objective. To analyze the risk of injury in athletes using Advanced Footwear Technology as well as the sporting, sociodemographic and anthropometric variables that influence this risk.
Method. Ambispective cohort study. Ninety-five athletes competing in events longer than 800 meters will be recruited. The primary variable will be the number of injuries, muscular and tendon, of lower limbs in the last 3 athletic seasons. Secondary and modifying variables will be: age, sex, weekly training load with and without AFT, weekly training frequency, completion of a complementary toning program and foot size. Potential confounding variables will be body mass index, main training surface and commercial footwear models used. The analysis will calculate the risk of injury in these athletes and assess the influence of confounders and trend analysis on the primary variable, stratified by potential confounders.
Expected results. To calculate the risk of injury as a function of sport, sociodemographic and anthropometric variables. Identify
