Mobility, Flexibility & Stability Screening

Miguel has a “neutral” thoracic which shows up in his loading style as a hitter. He has 45 degrees of rotation to the right and 55 degrees to the left. This is neutral and still is a factor in his loading mechanism as he uses inward torso rotation to take the slack out of his core. His scapular retraction is “neutral” as well, bordering “loose.” Scap retraction was 6 inches in both scaps. He is “loose” in internal and external hip rotation.   Core stability is excellent, which will factor into his energy transfer.

Force Plate Jumps

Miguel has a leg-to-leg imbalance in his jump tests. He favors his right leg 8% over his left and just needs to be monitored so as it doesn’t get worse. Counter movement jumps were more explosive than the squat-pause jumps. CMJ had a lift off force at 242% BW while SJ were 214% BW. This shows Miguel’s body prefers to transfer energy over a shorter time duration.

Force Plate Swings

Below is video of the swing analysis. I will walk you through this matched up with video.

Miguel loads into his whole foot but is short in back leg loading force at 94% BW. Front leg interaction with the ground is slightly low and dissipates over a longer period of time than we’d like.  Front leg numbers are 164% of BW which is lower than the 200% of BW we’d want. He prefers to create rotational speed, so he’ll need a more active heel interaction with the ground to increase turn speeds.

Back leg torque numbers are at the desired 45 Nm. Leg to leg transfer rates are good – shown by his x-axis timing numbers. He produces a great deal of torque force at 110 Nm.

However, there was a stark difference in torque once we added velocity. He took his lower half out of the swing more and just used his hands. We need to make sure he’s comfortable creating force against a time constraint, and I’m curious about his numbers against velocity due to his steepness as well.

KVEST Sequencing & Rotational Speeds

The 3d readings are on kinematic sequencing and rotational speeds.

Miguel has a neutral thoracic which requires a big upper body move to remove slack from the core. Instead of doing this with a scap load, he inwardly rotates his torso excessively. Torso inward rotation is 33 degrees which leads to limited energy transfer in the swing. We see the lead arm firing to start the swing because the torso has farther to open.  This limits bat speed, TTI and adjustability, Hip speeds can be improved with a more active front leg but are still “good” on the “Real Speed” scale at 675 deg/sec. Torso values get little climb because his hands fire early. Torso values are “fair,” at 800 deg/sec. Lead arm valuers are high but start the swing which increases TTI. Bat speeds are fast, but we would like to see TTI decrease, which will mean he’ll have to create better sequencing. Lead arm values are at 1100 deg/sec. Wrist values are high at over 2000 deg/sec.

Bat Sensor Data

Bat speed numbers ranged from 77-78 mph which ranks at the top of our organization. Attack angles are a major concern and were often negative. His bat gets on plane very late, which means his timing window is narrow and he HAS to be on time in the front of the zone. Adjustibility will decrease as a result because he’ll have to sell out to velocity and commit early to it. . Time to impact was higher than we’d like at 171-181 milliseconds. He swings fast, but takes longer to get up to speed.

Summary & Recommendations

• Attack angles are a MAJOR concern. There’s little chance of production at higher levels against more consistent velocity in his current path. He has to learn how to use torso angles to create swing plane versus using his hands to do so.

• Replace inward torso rotation with scapular load to stretch the middle of the body. This will improve sequencing, adjustability and bat speed.
