Integrating Data into Training

Driveline’s Research Approach

Driveline is built around a two-part research approach.

First, we evaluate our training through a review of peer-reviewed sports-science articles. Is there a tested or theoretical foundation for what we wish to implement with athletes?

Second, we do our best to replicate those studies in-house with our athletes to determine if those findings will work for our population of athletes.

Not until a drill or training methodology has met both parts of the two-part test do we include it with our programming.

Brief reviews of the research papers that drive our creative process are available at our Pitching Research webpage.

On-going Driveline Research Projects

Spin Rate

Investigating whether there is a relationship between grip strength and fastball spin rate. Using Trackman to collect spin rate data. Comparing the differences in spin rate between collegiate and professional pitchers.

Investigating whether fastball spin rate is dependent on velocity.

Motus Sleeve

Examining the difference in stress of throwing regulation baseballs compared to weighted baseballs.

Examining the stress of pulldowns compared to pitching off of a mound.

Examining the difference in stress between flat ground work and mound work

Long Toss

Examining the stress levels on the elbow, using the Motus sleeve, when throwing long toss.

Data will be collected on athletes throwing regulation and weighted baseballs.

Pitching-Ground Reaction Force

Examining the relationship between front and back leg force in a Rocker drill with Kistler force plates.

Hitting-Ground Reaction Force

Examining ground force production with Kistler Force plates

Hitting-Weighted Bats

Examining the long-term results of using overload and underload bats in training

Vertical Jump Force Production

Using our Tendo Unit we are examining the average & peak, power and velocity of our athletes in two and one leg vertical jumps. We are collecting the data to see if there are differences between professional athletes playing levels.

We are also examining whether there are relationships between peak/average measurements and throwing velocity.

Broad and Lateral to Medial Jumps

Examining the differences between professional and collegiate pitchers with two and one leg broad jumps as well as lateral to medial jumps.

Examining the correlation between the distances jump and throwing velocity in pulldowns and mound velocity.

Relevant research paper: Correlation of Throwing Velocity to the Results of Lower-Body Field Tests in Male College Baseball Players

Vision and Gaze research

Comparing hitters of different playing levels (professional and collegiate) to see if there are difference in gaze and pitch tracking.

Grip Strength

Examining the differences in grip strength between collegiate and professional hitters and pitchers.

Investigating whether there is a relationship between grip strength and velocity.

Investigating whether there is a relationship between grip strength and hitting metrics such as average or peak exit velocity.

Contributing Factors for Increased Bat Swing Velocity

Bar Velocity and Throwing Velocity

Investigate whether there is a relationship between velocity and power output in the bench press and throwing velocity. Post warm-up athletes bench press with set weights of 45lbs, 70lbs and 95lbs. We are collecting all data using Push band (linear position transducer) and Tendo unit.
