Abstract

The purpose of this investigation was to compare the effects of warming up with bats of varying weight on pre-impact bat linear velocity and on the timing and extent of segmental movement during the baseball swing, Sixteen varsity high school baseball players volunteered as subjects for the study The subjects were videotaped from overhead while hitting wiffle balls off of a hitting tee following each of three standardized warm-up routines using bats of varying weight Each subject performed 6-10 swings following each warm-up condition with the three best swings per condition selected for analysis, Pre-impact velocity of the impact point of the bat (measured electronically) and the timing and extent of segmental movements were compared, No significant intergroup differences for either pre-impact bat linear velocity or the segmental kinematic variables were found,
