About this study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

ControlBehavioural
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: Behavioral: Strength & Conditioning |

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 4 months
Secondary outcomes (4)
20 metre sprint
Athletes will perform 3 trials of a 20 metre sprint, with their time at 10 m and 20 m recorded. Timing will be done using a photo-electric timing system (SmartSpeed Pro, Fusion Sports, Chicago, USA). Each subject will wear a radio-frequency identification (RFID) bracelet assigned at the Open House sign-in; this device will allow timing for the sprint test. The fastest of the 3 trials will be used in analysis.
Measured: 4 months
Multiple Jump test
Athletes will perform 3 different types of jumps. For each of the jumps the athlete stands on a Smart Jump Mat (SmartJump, Fusion Sports, Chicago, USA), and holds a dowel across the shoulders, behind the head. A static jump requires the athlete to crouch down for a jump, pause at the bottom, and then jump as high as possible. A countermovement jump requires the athletes to crouch down and immediately jump back up for maximum height. Three submaximal practice trials of each jump will be done, followed by 3 test trials. The goal is maximum vertical jump, measured by time in the air. Then a series of elastic jumps, maximizing height but minimizing time on the mat, will be done for 60 seconds. The athletes will have a short, submaximal practice trial first. The jump tests will allow for a description of the athletes' power qualities, which are important for sport performance.
Measured: 4 months
Functional Movement Screen score
The FMS is a series of 7 tests including deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push-up, and rotary stability tests. The intent of the test is to screen athletes for the ability to complete functional activities that underlie more complex athletic skills. A low score on the FMS has been related to increased injury risk.
Measured: 4 months
Self-reported injury rates
Injury rates will be recorded during the study period by asking parents to contact the researcher when an injury occurs. A research assistant will also make bi-weekly phone calls to the parents/athletes in the study to ask about injury occurrence to ensure all injuries are noted. The type of injury (acute or overuse), involved body part, and treatment received will be documented as reported by the parent. No health identification numbers will be collected or healthcare practitioners contacted.
Measured: 4 months

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 May 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Y-balance score (time frame: 4 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2017; AzTrials last refreshed its copy on 3 Nov 2026.
