In running 70% of the lower limb, injuries are produced in the running segment. The vast majority of sports-related musculoskeletal injuries in young athletes are caused by overuse. Previous research has shown a clear association between running-related injuries and kinematic patterns, showing the existence of a causal relationship between biomechanical alterations and injures. According to the evidence, that real-time visual and auditory feedback based on gait retraining should be considered to treat injured runners or prevent injuries. However, no previous studies have been carried out on whether gait retraining decreases running-related injuries incidence in young triathletes. The investigators propose a study to determine the effect of gait retraining on the decrease in the number of running-related injuries and improve the running efficiency in young triathletes.

5 gait retraining sessions of continuous feedback in real time during running sessions; using videotape feedback, a digital metronome to increase step rate, and verbal feedback to reduce the tendency to heel strike upon ground contact. Verbal feedback is offered during the 25- to 30-minute running sessions following a series of drills aimed at improving running mechanics.

Surface Electromyography
Mean activation amplitude of gluteus medius.
Time frame: Baseline - 7 months
3D Kinematic Analysis
Peak angle at midstance defined as of the maximum pelvis joint angle between initial contact and toe-off. The tool to assess this variable would be an Inertial measurement unit (IMU) located at sacral vertebra S1
Time frame: Baseline - 7 months
Maximal Oxygen Consumption (VO2max)
Oxygen Consumption during running
Time frame: Baseline - 7 months
