Motion Capture: Baseball Swing

August 25, 2020 updated by: Patrick McCulloch, The Methodist Hospital Research Institute

The Kinetic and Kinematic Profile of the Upper Extremity During Progressive Phases of the Baseball Swing

The aim of this study will be to assess kinetic and kinematic data during different phases of baseball hitting progressions commonly employed in the rehabilitation setting.

Detailed Description

Study participants will undergo consent and history process. Subjects must meet inclusion and exclusion criteria prior to consent. Once consent is obtained, each subject will undergo instruction and training expectations of each swing phase. Once an adequate determination of proficiency has been met, each subject will undergo EMG and MOTUS sleeve placement on each upper extremity:

  • Forearm flexors
  • Forearm extensors
  • Medial epicondyle
  • Lateral epicondyle
  • Posterior rotator cuff musculature

Once participants have undergone appropriate calibration processes, they will perform listed swing progressions in a randomized order:

A. Dry swings - reduced weight (wiffleball) bat - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) B. Dry swings - normal weight bat - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) C. Tee hitting - normal weight bat - middle strike zone level - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) D. Soft toss - underhand toss from assistant - middle strike zone placement - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort) E. Simulated hitting - pitching machine - randomized strike zone placement - 5 swings light intensity (25-50% effort), 5 swings moderate intensity (50-75% effort), 5 swings high intensity (75-100% effort)

Baseball Batters
Participants must be healthy volunteers who accept all provisions of the study and agree to complete the program in its entirety. Participants should have their own bat and relative experience of at least 2 years of hitting a baseball. Ages accepted will be 16-40.
Behavioral: Motion capture participant

Once participants have undergone appropriate calibration processes, they will perform listed swing progressions:

  1. 15 dry swings with a wiffle bat at low, medium and high effort
  2. 15 dry swings with a weighted bat at low, medium and high effort
  3. 15 swings off of a tee at low, medium and high effort
  4. 15 swings at an underhand toss at low, medium and high effort
  5. 15 swings from a pitching machine at low, medium and high effort
