- Abstract
- Limited glenohumeral range of motion of the throwing shoulder in baseball players has been shown to be a risk for shoulder and elbow injury. Although there are many established programs that have been shown to improve glenohumeral range of motion, no program has been shown to effectively improve throwing velocity and range of motion. Identifying a throwing program that can improve range of motion could help to decrease the risk of shoulder injury in a way that is easily marketed to a performance-minded participant. Therefore, the purpose of this study was to determine the extent to which the Velocity Plus Throwing Program could alter shoulder range of motion. 32 youth baseball players between the ages of 8-17 years old completed the study; 12 in the intervention group and 20 in the control group. The participants underwent range of motion testing to measure dominant internal rotation (IR), dominant external rotation (ER), dominant total arc of motion (TAM), glenohumeral internal rotation deficit (GIRD), external rotation gain (ERG), and total arc of motion difference (TAMD). Participants in the intervention group demonstrated a significant TAM decrease of 10.1 ± 4.5 degrees (t(30):0.95, p=0.03). No significant difference was found with dominant IR, dominant ER, GIRD, ERG, or TAMD. Further, no significant change in velocity resulted from the intervention, with a mean of increase of 1.2 ± 1.1 MPH (t(30):-1.09, p=0.29). Future research should focus on a larger sample size to increase the power of the findings and identify aneffective performance program that can be utilized to improve athletic performance and help prevent injury.
