Summary
The purpose of this study is to determine the effect of baseball weight on the pitching motion and joint forces in youth baseball pitchers. The study will also investigate how the baseball weight affects grip strength, which is also correlated with injury.
The study will recruit two cohorts of 20 youth male baseball players each (ages 7-9 and 10-12). Each participant will complete 1 visit (visit will take 2 hours).
Inclusion/Exclusion Criteria
Inclusion:
- Amateur male baseball players of ages 7-12
- Minimum of 1 season of baseball experience
Exclusion:
- History of shoulder or elbow injury requiring surgery or cessation from throwing
- Players with a history of shoulder or elbow pain over the past 6 months
- Players with a history of lower extremity or back pain over the past of 6 months
- Players who have pitched in a competitive game within 4 days of anticipated testing
- Players unwilling to adhere to 2 days of rest from competitive pitching after laboratory testing
