Overall Efficiency Grade: 71.25/100

Mobility, Flexibility & Stability Screening

Trent is in the “loose mover” category. His thoracic mobility numbers (68 and 75 degrees) are near the “hyper-mobile” range on the scale. This indicates that Trent will have to have a longer loading pattern to create stretch in his body. Timing is an important factor for Trent, as he will need more time to take the slack out of his core.

Force Plate Jumps

Both the counter movement jumps and the squat jumps show some leg to leg imbalances. More of an emphasis of unilateral leg work needs to be done with imbalanced athletes or the bias will get worse and lead to hamstring pulls.

Squat jumps are more explosive for Trent averaging 138% BW of explosiveness. Counter movement jumps are at 125%. His body creates energy over a longer period of time. Combined with what we know about his mobility, it is important he stays with a long, slow loading mechanism when he hits.

Force Plate Swings

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

Trent does an excellent job loading and storing energy in his back leg. Swings average 104% body weight in the back leg load and he maintains optimal force during his positive move producing good body control. His 104% BW back leg force is above the top range of our grading scale.

He torques his femur during his positive move up to 70 Nm. Torque production is well above the desired 40-50 Nm.

We look for the front leg post to double the back leg force. He approaches 200% BW closely with is front leg, but just as important, his front leg force spikes rapidly (shown in the video).

X axis timing numbers were equally as impressive. His leg to leg transfer is one of the fastest we’ve ever tested. This is one of the most important metrics on the force plate and has one of the best correlations to rotational speed.

KVEST Sequencing & Rotational Speeds

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

The inefficiency Trent has in his swing is kinetic sequencing. In his lab swings, Trent landed across his back shoe. In players that have this stride style, we often see the arms lead the sequence in order to clear the closed-off body. Errors in sequencing limit reaching maximum speed achieved through proper energy transfer. From the graph, you can see his hips and torso are connected (red and green lines) and his arms and bat are connected (blue and brown lines), but the body is disconnected from the arms/bat.

Speed values in the lower body grade in the highest level. Rotational velocities are 737-791 deg/sec. Trent’s torso speeds are not as fast however, and grade “below average” for professionals. The poor torso speed is derived from one of two places:

• Core instability (we did not screen)
• Lack of necessary slack taken from an extremely mobile thoracic

Lead arm climbs are slightly below average, which we would expect on an out-of-sequence graph.

Bat Sensor Data

Excluding the outliers, Trent sits 70-71 mph on his bat speed. His high bat speed (75 mph) ranks in the top 10 of the org. Time to impact numbers are 168-179 milliseconds, which is top 25% of the org. Hand speed metrics are excellent at 24-25 mph.

Summary & Recommendations

Trent is a “loose” mover with an appropriate, long loading mechanism. Leg force data is outstanding and the strength of his swing. However, despite his bat speed being very good, he does have speed to gain with better sequencing.

Recommendations:

• Hold the scap load longer. The scap load will further stretch the core and connect the arms to the rest of the body.
• Work core stability and unilateral leg work as an emphasis of his strength and conditioning plan.
