Do Young Triathletes Have a Greater Predisposition to Suffer Running Injuries

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.

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Triathletes included in the Triathlon Plan in High Performance of the Valencian Community in Spain.
  • Reported running a minimum of 2 days per week for the last 3 months with no reported injury.
  • Worst pain rated a minimum of 3 out 10 on a numerical rating scale (NRS) for pain (0=no pain, 10=worst possible pain)

Exclusion criteria

  • Previous musculoskeletal surgery.
  • Neurological impairment
  • Structural deformity in the knee.
  • Pain suffered by trauma or sports activity, having stopped running or receiving additional treatment outside the study.

Treatment and study plan

Gait retraining

Other

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.

Primary outcomes

  1. Surface Electromyography

    Time frame: Baseline - 7 months

    Mean activation amplitude of gluteus medius.

Secondary outcomes

  1. 3D Kinematic Analysis

    Time frame: Baseline - 7 months

    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

  2. Maximal Oxygen Consumption (VO2max)

    Time frame: Baseline - 7 months

    Oxygen Consumption during running

Other outcomes

  1. Self-report Questionnaire about Running-related injuries

    Time frame: Baseline - 7 months

    By means of a self-report questionnaire according to previous research in triathletes to document the incidence of overuse injuries previous and post gait retraining protocol season. Higher scores (number of injuries) mean a worse outcome.
