HITTING              
1, Dynamic Balance          
  Tracking the center of gravity or center of mass from start to finish
             
2, Posture            
  Tracking the angle of the upper half of the body in relationship to the lower 
  half of the body throughout the motion    
             
3, Stride Length          
  The displacement of the front foot from the beginning of the motion to the foot
  striking the ground and the percentage of the body's height
             
4, Stride Tempo          
  Indicates the total time the stride foot was off the ground
             
5, Foot Strike Angle          
  The angle of the front foot as the front heel reaches the ground
             
6, Stride Line            
  How in line the stride foot is with the center of home plate
             
7, Head Movement Stride        
  Head movement from foot lift to foot strike    
             
8, Head Movement Swing        
  Head movement X, Y & Z  from launch to contact  
             
9, Blocking            
  How far the C.G. drifts forward after directional shift (linear to angular)
             
10, Sequential Rotation          
  Peak dis-association in degrees of the upper half of the body from the lower 
  half of the body        
             
11, Angular velocity          
  Angular velocity of the body's center of mass  
             
12, Axis of Rotation          
  The location of the center axis of which the body rotates around
             
13, Bat Lag            
             
             
14, Bat Speed          
  Peak angular velocity of the bat head    
             
15, Bat Quickness / Acceleration        
  Elapsed time from the launch of the bat until contact is made
