| Research Abstract |
The purpose of the present project was to determine the kinematic factors influencing the flight distance of the batted ball in baseball. An experimental study and a simulation study were conducted to examine the inter-relations among the kinematic characteristics of the pitched ball, bat swing and batted ball. The results of the studies indicated consistently that the trajectory and speed of the bat swing immediately before impact and the rolling velocity of the bat around the long-axis influence the flight distance of the batted ball.
