A motion system collected 120-Hz data from 14 baseball adult hitters using normal and choke-up bat grips. Six swings were digitized for each hitter, and temporal and kinematic parameters were calculated. Compared with a normal grip, the choke-up grip resulted in 1) less time during stride phase and swing; 2) the upper torso more opened at lead foot contact; 3) the pelvis more closed and less bat linear velocity at bat-ball contact; 4) less range of motion of the upper torso and pelvis during…

Effects of Changes in Bat Grip Position on Baseball Bat Swing Timing, Ground Reaction Force, and Muscle Activation Characteristics
This study aimed to clarify the eŠects of changing to a short bat grip position from the long bat grip position on baseball bat swing timing, peak ground reaction force with the front leg, and
Kinematic comparison of baseball batting off of a tee among various competition levels
Comparison of batting kinematics across competition levels showed differences in angular positions between competition levels during the five phases of the swing, with the greatest differences seen between the youth and professional batters.
Relationship of pelvis and torso angular jerk to hand velocity in female softball hitting
Lack of significant findings suggests a relationship between jerk and angular hand velocity does not exist within female softball hitting, and future research should investigate the timing of minimal jerk through the acceleration phase as a predictor ofangular hand velocity, rather than the value of jerk itself.
The purpose of this study was to identify effect of moving the center of gravity of the body and rotating the torso when batting pitches with varying velocity. The subjects were 10 experienced
The Kinetics of Swinging a Baseball Bat.
Results indicate that players act to mostly "pull" the bat during their swing until just prior to ball impact, at which point they rapidly increase the moment on the bat, providing novel insight into the forces and moments used to swing baseball bats.
The effect of pitch type on ground reaction forces in the baseball swing
Batters had a similar loading mechanism and initial weight transfer from back foot to front foot regardless of pitch type, but peak front foot GRFx and GRFz occurred with significantly different magnitudes and at significantly different times, depending on the pitch type and hit result.
The purpose of this study was to explore for optimum motions of the upper body in order to generate a high bat-head speed through computer simulation of baseball tee batting. A bat and upper body
A Choke-Up Grip Facilitates Faster Swing and Stride Times Without Compromising Bat Velocity and Bat Control
Introduction Historically, since major league baseball established its modern day roots in the early 1900's, the best hitters in the game have studied hitting mechanics to improve their performances


The Mechanics of Batting: Analysis of Ground Reaction Forces and Selected Lower Extremity Kinematics
Abstract The purpose of this study was to examine variations in ground reaction forces and selected lower extremity kinematics during the stride and swing phases of batting. High speed photography
Hitting a baseball: a biomechanical description.
Three-dimensional kinematic and kinetic data are used to define and quantify biomechanics during the baseball swing and show that a hitter starts the swing with a weight shift toward the rear foot and the generation of trunk coil.
A Kinematic Analysis of the Baseball Batting Swings Involved in Opposite-Field and Same-Field Hitting
Abstract The purpose of this study was to examine the mechanics of hitting a baseball to the same and opposite fields. Twenty male subjects were assigned to one of two groups according to their
Relationship between bat mass properties and bat velocity
The relationship between bat mass properties (mass and moment of inertia) and bat velocity (linear and angular) was investigated for baseball and softball. Seventeen male collegiate baseball players
Three-Dimensional Interactions in a Two-Segment Kinetic Chain. Part I: General Model
The motion of a body segment is determined by joint torques and by the motions of the segments proximal or distal to it. This paper describes a three-dimensional model that was used to determine the

Quantitative evaluation of multiplicity in epidemiology and public health research.
The results indicate a type 1 error rate substantially higher than the traditionally assumed level of 5% (p < 0.05), which should be reported in epidemiologic and public health research investigations that include multiple statistical tests.
Direct linear transformation method for three-dimensional cinematography.
This study evaluated the “direct linear transformation” method developed by Abdel-Aziz and Karara (1971) for use with high-speed cine techniques and found it to be effective and efficient.
