This study focused on the pronator-flexor mass of the elbow and its role in the overhead throwing motion. This specific muscle group is responsible for primary pronation and flexion at the elbow joint, while also reducing valgus stress from compromising the ulnar collateral ligament.
Twenty-three participants were put through a short throwing progression that was focused on their velocity and overall distance thrown from a standing position. After baseline testing was completed participants underwent a short intervention to determine if the intervention would impact all dependent variables. Experimental and non-experimental groups were compared using a repeated measures ANOVA which found no statistically significant difference.
The hypothesized relationship between the flexor-pronator group strength and the elbow range of motion would have resulted in increased overall valgus stability of the UCL due to an active warm-up which, in turn, would have increased pitching velocity and distance. This theoretical improvement would not only have decreased the possibility of injury as well as pain but improved the individual's overall functionality.
