The paper “Quantitative Assessment of Glenohumeral Translation in Baseball Players” (The Amer. J. of Sports Med., 2004: 1711–1715) considered various aspects of shoulder motion for a sample of pitchers and another sample of position players (“glenohumeral” refers to the articulation between the humerus (ball) and the glenoid (socket)). The authors kindly supplied the following data on anteroposterior translation

(mm), a measure of the extent of anterior and posterior motion, both for the dominant arm and the nondominant arm.
