Brief Summary

Whether the use of customised mouthguards is effective in improving the athletic performance of baseball and softball performance

Detailed Description

This study recruited 45 baseball and softball players, including 30 fielders and 15 pitchers. Using a randomized crossover experimental design, the study was divided into randomised divided into customised mouthguards trial (MG) and control trial (CON) without temporal positioning. After the participants wore the mouthguard, they performed the vertical jump and grip strength tests sequentially. At the end of the test, depending on the pitcher or fielder, a baseball pitching ability test or a hitting ability test was conducted using a radar baseball tracking system. It is expected to analyze the vertical jump height, grip strength, pitchers' straight and changeup ball speeds, rotation speeds, degree of displacement, on-base and off-base locations. Hitting ability was expected to be documented with respect to initial velocity, elevation, and consistency of elevation.
