At Driveline, one in every of our elementary missions is to “clear up hitting.” Tall activity, proper? Whereas we perceive that hitting is much too dynamic and complicated to ever be fully solved, working with this purpose in thoughts permits us to function on the sting of innovation — the place the rubber meets the street. If we’re going to speak concerning the chopping fringe of hitting growth, our movement seize lab must be the place we begin. The significance of biomechanics is finest summarized by this quote from the Altis Foundations Course:
“Finding out biomechanics is in the end undertaken with a purpose to assist us grasp or higher perceive the bodily legal guidelines of movement which underlie all motion. The coach’s job is to supply significant instruction primarily based on applicable analysis of bodily motion expertise in comparison with our understanding of the proper technical mannequin.”
Come alongside for the journey as we present you the explanation why hitting biomechanics is a subject about which we are able to all get excited.
Grow to be the Hitter You Need To Be
Described as merely as doable, the movement seize lab lets us flip this…
However we aren’t simply making skeletons of everybody’s swing and calling it a day. The movement seize lab additionally permits us to view the kinematics (mechanics) and kinetics (forces) of your swing.
Each angle is captured with sub-millimeter accuracy whereas pressure plates acquire knowledge on the way you work together with the bottom throughout your swing. For instance, right here is an athlete’s swing synced to his kinematic sequence: pelvis, torso, higher arm, and arms.
And right here is one other participant’s hip-to-shoulder separation:
As you’ll be able to see, the extent of element is fairly granular, however now it’s time to ask the all-important query: How can we use this data to truly make you a greater hitter?
How will we use it?
Fast instance: right here’s the swing of one in every of our athletes:
After watching him hit throughout his assessment, one of many issues I observed was a transfer he makes throughout the stride section of his swing. That is the transfer I’m speaking about:
What I see right here is the pelvis and torso beginning to get extra upright (perpendicular to the bottom) earlier than he begins his rotational sequence. For reference, that is what the pelvis and torso would appear like at 0° of ahead bend:
Under is identical swing, however on the precise you’ll see two graphs. The higher is measuring pelvis ahead bend, and the decrease is measuring torso ahead bend. I like to recommend watching this GIF a minimum of thrice.
First, watch the skeleton’s pelvis and torso. Second time, watch solely the pelvis graph, and spot how as he strides the pelvis loses ≈10° of bend in a brief time frame.
Lastly, watch the torso graph, and spot the way it loses ≈10° of bend over a barely longer time frame. When you watch it a fourth time, you’ll have an ideal alternative to view the connection between the skeleton’s segments and the accompanying graphs.
That is what his posture seems to be like earlier than he begins to face upright. Discover that on the precise, neither of the graphs present any lack of bend but.
That is what it seems to be like after the pelvis and torso have each made their strikes to turn into extra upright:
A side-by-side view helps to visualise the variations between these two positions. The 2 issues of be aware are:
- The pelvis and torso have turn into extra upright (nearer to perpendicular in relation to the bottom);
- The athlete has come up and out of his hinge place. In different phrases, the angle between his higher and decrease half is extra obtuse (larger than 90°).
Is that this transfer a “swing flaw?” Not essentially.
Personally, I feel some hitting coaches are manner too fast to label sure actions as “swing flaws,” however that’s most likely a weblog put up for the long run. Nevertheless, a greater query to ask can be:
“How does this motion have an effect on what occurs downstream on this athlete’s swing?”
On this case, my remark is that the aforementioned transfer may very well be inflicting him to have a extra down and round bat path with a decrease assault angle. Once more, these are my observations. What do you see?
After we checked out his evaluation knowledge, two issues stood out:
- He had bother constantly squaring the ball up. His bat velocity ought to yield greater exit velocities, however it doesn’t, that means that he’s chopping baseballs and shedding out on potential exit velocity due to a low smash factor on most of his swings.
- Low common assault angle. That is most definitely a bi-product of his down and round bat path.
The excellent news is that we’ve got drills particularly designed to repair these points! The facility of teaching with biomechanics is the objectivity it offers us when evaluating and assessing motion. Then, from a sensible standpoint, we are able to use this data to create focused and particular coaching applications, reassess the athlete, and consider progress.
