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)

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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.
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
