Biomechanics of Throwing


Throwing is one of the most important skills in softball.  If you can consider the biomechanics of throwing, you will have a good understanding of the mechanics for teaching and error detection and correction purposes.  Following is an analysis of a right handed softball player and their throwing.

Biomechanics of throwing for a right handed thrower

(no following action required)

Objectives of the Skill

  • To get the ball to a specific location with high velocity under varying conditions

Special Characteristics

  • Non – repetitive closed skill

Identify Top-flight Performance of the Skill

  • An athlete with a longer arm will improve the effect of the throwing lever
  • Strength
  • Experience level

Technical Progressions

  • begin with the feet shoulder width apart to facilitate balance
  • step forward with the right foot transferring the weight (center of gravity) to that foot
  • rotate upper body back to the right to facilitate the coiling effect
  • step forward with the left foot toward the target
  • begin rotation toward front to the left with the hips first, then shoulders then elbow and wrist
  • right elbow moves in front of the body bringing the ball and the wrist in line with the target
  • snap the wrist in front of the body at the target on release of the ball
  • follow through with deceleration of the upper body and arm extend down past the hips to the left

Evaluation and Assessment Tools

  • video analysis
  • charts and graphs
  • self evaluations
  • statistics from games
  • general observation


Most common errors

  • not looking at target
  • ball too far or too close to the body
  • not stepping toward the target
  • no follow through
