PITTSBURGH – Using visual data (and using it correctly) is a huge part of getting the most out of SwingTracker. Today we will look at a pair of swings that may seem similar, but are actually quite different, and understand why – through data visualization! – they are that way.

Take a look at two of the swings from Illustration 1.0 below: the ninth swing in the session that totaled a 4.2 overall score (the first score on the third row) and the second swing in the session that totaled a 5.4 overall score (the second score from the left on the first row).

While there are many metrics and components that factor into the overall swing score, we will look at Max Barrel Speed and examine how it affected each score differently.

Below, in Illustration 2.0, we can see the Max Hand Speed and Max Barrel Speed results from the swing that measured a 4.2.

The Max Hand Speed measured out at 17 mph, while the Max Barrel Speed was 48 mph.

Now let’s go further and look at Illustration 3.0, a 3D visual of that swing.

As the 3D visual shows us, the Max Barrel Speed of 48 mph occurred well before impact (as designated by the blue line). Because of this, we can gain more insight into the swing and see one of the reasons why this swing scored rather low during this session.

Since it’s ideal for Max Barrel Speed to occur at impact (therefore creating a higher exit velocity), the fact that barrel speed started to decrease as the bat got closer to impact shows that the timing of this swing was off.

While that wasn’t the only reason for the low score, it was definitely one of the main ingredients

Now let’s view the other swing, the swing that garnered a score of 5.4.

Take a look at Illustration 4.0 and Illustration 5.0 below:

While the Max Barrel Speed of this swing was only 4 mph faster than the other swing, it occurred much closer to impact.

This, as we know, is a good thing and explains one of the reasons why the overall swing score was much higher.

Moreover, common sense will tell us if one part of the swing improved (higher barrel speed + higher barrel speed occurring very near impact), then other parts of the swing likely improved – trigger to impact time, hand speed, impact momentum…etc.

Ultimately, that results in a better overall score.

By using the 3D viewer to pinpoint when Max Barrel Speed occurred, we are able to gleam a huge chunk of information that gives insight into the complexities of the baseball swing.

Hooray for visual data!
