Description
Background: Baseball pitchers commonly suffer shoulder and elbow injuries. Previous research on the relationship between pitch velocity and upper extremity kinetics has been limited to laboratory settings, but recent strides in markerless motion capture have allowed analysis of in-game baseball pitching biomechanics.
Purpose: To provide normative data of in-game pitching kinetics and assess the relationships between pitch velocity and shoulder and elbow kinetics. Hypotheses: It was hypothesized that 1) pitchers with higher velocity will also have higher throwing arm kinetics, 2) the relationship will be stronger within pitcher than between pitchers, and 3) the intrapitcher relationship between throwing arm kinetics and fastball velocity will remain consistent across multiple outings.
Study Design: Descriptive laboratory study. Methods: A retrospective review of markerless motion capture data collected during NCAA Division I baseball games was performed. Data from 183 college pitchers were included in this analysis. Multilevel models were used to assess the relationships between pitch velocity and kinetics. ICCs were used to assess the intrapitcher relationship between kinetics across multiple outings.
Results: The inclusion of random slopes did not meaningfully reduce intrapitcher throwing arm kinetic variance. Additionally, the intrapitcher relationship between throwing arm kinetics and ball velocity did not remain constant across multiple outings.
Conclusion: Pitch velocity and in-game throwing arm kinetics did not have a strong intrapitcher relationship, which is different than the results of previous laboratory analyses. Intrapitcher relationship between fastball velocity and throwing arm kinetics does not remain consistent across multiple outings. Additionally, this study provides normative in-game kinetic data for baseball...
