• Ithaca College Study on the Stabilizer
  • Bio-Mechanical Study

Coaches Edge is proud to present the following Scientific study done over the past 2 ½ years on the bio-mechanical benefits of the Stabilizer Hitting System. This study was executed by world renowned Deborah King PHD, Associate Professor Bio-mechanics Department, Exercise and Sport Sciences, Ithaca College, Ithaca, NY.

Whether you are an avid hitting coach/instructor or are searching for the latest proven teaching techniques in hitting, you will find this study very compelling. Any questions on the study results should be directed to Coaches Edge.

NOTE: Study does not include the added dynamics of the Buggy Whip on swing; study is ongoing and will have results in the near future…Thank you for your interest!


"Twenty moderately experienced, though currently non-active, baseball and softball players practiced batting for one week either taking 30 practice cuts using their typical swing or 30 practice cuts a day using the Stabilizer. The players’ swings were compared prior to starting practice, immediately following the week of practice and one week after practice ended. Batters who trained with their typical practice swings had greater forward hip motion and a greater forward shift of their weight after the week off as compared to their initial swings. In comparison, batters who trained on the stabilizer did not display additional forward hip motion or a greater shift of their weight after training for a week and taking one week off. These results may indicate that with practice, moderately experienced batters may, over several days of practice, shift their weight more to the front leg with greater forward hip motion. Taking practice swings on the stabilizer appears to prevent this phenomenon." Read the full report...

"A tremendous amount of time and energy has been dedicated to the development of conditioning programs, mechanics drills, and rehabilitation protocols for the throwing athlete. In comparison, a significantly smaller amount has been spent on the needs of the hitting athlete. Before these needs can be addressed, an understanding of mechanics and the demands placed on the body during the swing must be developed. This study uses three-dimensional kinematic and kinetic data to define and quantify biomechanics during the baseball swing. The results show that a hitter starts the swing with a weight shift toward the rear foot and the generation of trunk coil. As the hitter strides forward, force applied by the front foot equal to 123% of body weight promotes segment acceleration around the axis of the trunk. The hip segment rotates to a maximum speed of 714°/sec followed by a maximum shoulder segment velocity of 937°/sec. The product of this kinetic link is a maximum linear bat velocity of 31 m/sec. By quantifying the hitting motion, a more educated approach can be made in developing rehabilitation, strength, and conditioning programs for the hitting athlete." Read the full report...
