To design interval throwing programs for baseball players other than pitchers from 13 years of age to the college level.
The authors recorded throws to base, distance of throws, and perceived effort of throws at 4 levels of play. For catchers they also recorded number of throws to the pitcher, number of sprints to first or third base, and time in the squat stance. From these data they designed throwing programs specific to outfielders, infielders, and catchers.
No significant difference was found between the number of throws and distance of throws for infielders and catchers across all age groups. The mean distance of throws differed significantly between 13-year-olds and all other levels of play.
The authors devised 1 program for infielders and catchers of all age groups, 1 program for 13-year-old outfielders, and 1 for all other levels.
