Data-based interval throwing programs for baseball position players from age 13 to college level

Objective: To design interval throwing programs for baseball players other than pitchers from 13 years of age to the college level. Design: The author s recorded throws to base, distance of throws, and perceived effort of thro ws 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 squ at stance. From these data they designed throwing programs specific to outf ielders, infielders, and catchers. Results: No significant difference was f ound between the number of throws and distance of throws for infielders and catchers across all age groups. The mean distance of throws differed signi ficantly between 13-year-olds and all other levels of play. Conclusion: The authors devised I program for infielders and catchers of all age groups, 1 program for 13-year-old outfielders, and 1 for all other levels.
