The effects of 6-week training programs on throwing accuracy, proprioception, and core endurance in baseball

With a limited number of outcomes-based studies, only recommendations for strength-training and rehabilitation programs can be made.

To determine the extent to which throwing accuracy, core stability, and proprioception improved after completion of a 6-week training program that included open kinetic chain (OKC), closed kinetic chain (CKC), and/or core-stability exercises.

A 2 x 3 factorial design.

Division III college.

19 healthy baseball athletes with a control group of 15.

Two 6-week programs including OKC, CKC, and core-stabilization exercises that were progressed each week.

Functional throwing-performance index, closed kinetic chain upper extremity stability test, back-extensor test, 45 degrees abdominal-fatigue test, and right- and left-side bridging test.

There was no significant difference between groups. An increase was evident in all pretest-to-posttest results, with improvement ranging from 1.36% to 140%.

Both of the 6-week training programs could be used to increase throwing accuracy, core stability, and proprioception in baseball.
