Research & Ressources

In the end, the research and numbers are what drive Balance Hitting, LLC. Life is based on understanding what the numbers mean and too many times the numbers are either ignored. The following is a sample collection of research studies, journal articles, and other digital information nodes that we believe can support any hitter in becoming the best hitter possible.

Hitting Terms

  • Exit Ball Speed: The speed of the ball after it is struck by the hitter's bat.
  • Implement Weight Training: Training that includes under and overload percentages (%).
  • Kinetic Link Theory: Large proximal base muscles passing momentum to smaller distal muscles.
  • Plyometric exercise: Powerful, quick movements that require a pre-stretch, activating the stretch shortening cycle.

Training and using the micro muscles of the swing are key in developing an Elastic Stretch and Kinetic Sequence. Both are absolutes in developing a dynamic and explosive on-time swing.
