3 simple ways to apply VBT & your Bar Sensei today

by Scott Damman, Assess2Perform.  There sure has been a lot of noise this year around sport tech, and specifically Velocity-Based Training (VBT) / barbell tracking.  The noise has created a lot of confusion and misinformation.  I bet some of you are feeling VBT fatigue.  I don't blame you. This week I had a nice call with one of our customers, Todd Barnes C.S.C.S., who heads up Athletic Development at Arcadia University.  As we were covering some basic questions he had related to setting up team & athlete rosters within the A2P Sport App, the conversation went into the application direction.  Of course, I could take this in numerous directions, and did take it down a few paths; but it really...

Barbell VBT: are we really measuring what counts?

by Scott Damman, Assess2Perform.  Being in the VBT technology space with the Bar Sensei we look beyond simply displaying a number.  We study training outputs to see if there is valuable information that maybe is getting missed.  Sometimes we need to challenge the traditional way and ask questions -- is the standard metric, or what I call legacy data, the right metric?  In June I guest wrote on SimpliFaster an article Is It Time for Coaches to Rethink Velocity-Based Training?  The point of the article was to create some fresh conversation related to the VBT metrics that have been used traditionally, and challenge those metrics. I want to come back to one metric in particular, MPV (mean propulsive velocity).  There...

What the heck is going on Eccentrically?

Based on the conference tweeting, this past weekend's High Performance Development Conference 2017 hosted by Athletic Lab, looked to have some refreshing presentations.  Seeing presentations around RFD, the eccentric side, and how they work together is great. Just last month, Scott Damman of Assess2Perform published an article titled Is It Time for Coaches to Rethink Velocity-Based Training? The article hit on the fact that we have become stagnant with legacy data, and laid out some alternative measurements and fundamentals to consider.  RFD (the Bar Sensei POP-100 metric) and the Eccentric side were both discussed in the article, but for this post we will keep it on the eccentric side. News flash, VBT is not limited to the concentric side, eccentric...

Cost saver with the new iPad

Good news for those looking to buy a new Apple device to run the Assess2Perform Bar Sensei and Ballistic Ball.  Just over a month ago Apple very quietly announced it was bringing back the original iPad; meaning, there is no model tail name like Mini, Air, or Pro.  This is sold as the plain old iPad, with the ideal 9.7 inch display and the fast A9 chip-set (64-bit). The good news is now you can get a hold of a new iPad for $329.  I expect this should also translate to lower costs in the refurbished market as well, so keep an eye on used AIR & AIR2 models. The minimum Apple (iOS) requirements to run the A2P products is...

Validity of Bar Sensei in Determining Barbell Velocity and a Novel Measurement of Starting Strength

Zachary J. Switaj, Dustin J. Oranchuk, Tracey Robinson -- Adams State University (Alamosa, Colorado) (Presented at the ACSM Rocky Mountain chapter meeting, April 2016) ABSTRACT Velocity based training (VBT) can be used to determine loading, track progress and monitor fatigue in the weight-room.  Traditionally, technologies such as force plate systems or linear position transducers (LPTs) were needed to implement VBT.  Force plates and LPTs are often outside the budget of many programs.  Accelerometer systems have become popular for implementing VBT as they are significantly more affordable.  The Bar Sensei™ accelerometer by Assess2Perform™ (Boulder, CO), claims to accurately measure traditional VBT metrics such as peak velocity, as well as a novel measurement called POP-100, which measures the bar velocity during the first...
