Enrollment: 30
Sex: ALL
Minimum age (years): 11
Maximum age (years): 18
Standard ages: CHILD
ADULT
Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Exercise Program Alone Exercise Program with External Cueing Device
Primary purpose: PREVENTION

Brief summary: The goal of this study is to find out if a tool called an external cueing device (ECD) can help young swimmers improve their shoulder function. An ECD is a tool that limits arm movement and gives the swimmer a target to focus on while doing exercises. The main questions this study will answer are:

* Does using an ECD during certain exercises improve muscle strength?
* Does using an ECD while exercising help with shoulder stability?

Participants will:

* Test their shoulder muscle strength and stability at the beginning of the study.
* Complete 8 exercises as part of their regular dry-land training program for 6 weeks.
* Repeat the same tests after 3 weeks and again at the end of the study.


Eligibility criteria: Inclusion Criteria:

* Healthy Volunteer Adolescent Swimmers
* Member of CMSA

Exclusion Criteria:

* Swimmers under the age of 11 years of age.
* Swimmers that are not registered as athletes through United States Swimming.
* Swimmers that are not enrolled in Age Group III, Senior 1, Senior 2, or Senior 3
* Swimmers not attending practice due to an injury (i.e., shoulder, back, etc.).
* Swimmers currently not participating in a dryland program offered through CMSA.
