Biochemical differences between left- and right-handed pitchers lead to a higher population of left-handed pitchers and an increased risk of shoulder injury for those pitchers, according to a study published in The Journal of Sports Medicine.
Researchers used three-dimensional, high-speed video data on fastballs from 84 colligate baseball pitchers to examine the pitching mechanics and resultant kinetics on the throwing shoulder and elbow. Fifty percent of the pitchers in the database were left-handed.
The data found that the non-throwing shoulder external rotation, elbow flexation at stride-foot contact and shoulder abduction during acceleration were greater in left-handed pitchers. However, the shoulder abduction at stride-foot contact, shoulder horizontal abduction at stride-foot contact and peak horizontal adduction angular velocity were less for left-handed pitchers.
Left-handed individuals make up approximately 10 percent of the general population, yet 30 percent of pitchers in Major League and Division I college baseball. Researchers suggest physicians pay close attention to left-handed athletes because they may be at greater risk for shoulder injuries.
