Brief Summary

The purpose of this study is to explore the effects of a strength \& conditioning (S \& C) program on risk factors for injury (Y-balance and Functional Movement Screen scores), as well as parent reported injury occurrence in 12-16 year old male and female athletes. Forty girls and 40 boys aged 12-16 will be recruited; half will participate in supervised S \& C sessions 2-3x/week while the other half will continue with their regular sports and activities. Risk factors for injury and performance indices (20 m sprint and multiple jump test) will be assessed before and after the 4 month study. Injury occurrence will be recorded via bi-weekly phone calls to the parent and athlete.

Outcome Measures

Primary Outcomes (1)

• Y-balance score

  Using the Y Balance Test Kit (Functional Movement Systems, Inc., Chatham, Virginia), the athlete stands on one leg, hands on hips, while pushing a wooden block as far forward as possible with the opposite foot. The displacement of the block is recorded. The athlete is allowed 4 practice trials in each of the 3 test directions: anterior, posteromedial and posterolateral. Three test trials are then conducted for each leg in each direction, with short rest breaks between trials. The average reach distance for each leg for each direction will be normalized to leg length and used in analyses. This test has shown moderate to excellent reliability. Lower scores and asymmetries on the Y-balance test have been linked with an increased risk of injury.

Study Arms (2)

Strength & Conditioning

EXPERIMENTAL

Supervised S \& C program based on the Long Term Athlete Development Model. Participants will attend 2-3 sessions per week for about one hour each session for 4 months. The comprehensive program will include strength and power training as well as plyometrics, agility and flexibility exercises.

Behavioral: Strength & Conditioning

Control

ACTIVE COMPARATOR

Athletes in the control group will continue with their usual sports and activities but will not receive any type of training.
