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...

Bar Sensei – Unwrapping Velocity Based Training

by Sam Portland, guest writer.  Having played around with the Bar Sensei now for a few months I feel I’m quick getting my feet under the table with regards to the product.  Sitting here now I wish I had purchased the Ballistic Ball, but I am sure I will at some point.  For me personally I like to be able to quantify training quite easily with a good degree of accuracy.  As a consultant strength and conditioning coach for teams, using the Bar Sensei is a real practical and transferable kit piece with a very reasonable price tag. Using the Bar Sensei to map out a Force Velocity Trace The reason why I purchased Bar Sensei is because I feel...

From the training floor, comparison of 2 VBT (velocity-based training) technologies

Bar Sensei / GymAware bar speed comparisons Date:  March 25, 2017 Location:  NSCA Headquarters, Colorado Springs, CO – USA During an Athletic Development clinic (Hammer Clinic -- Rocky Mountain Regional, hosted by NSCA) we had the opportunity to experiment with 3 distinct VBT products – Bar Sensei, GymAware, and Push.  The goal of this informal project was to use the products together in a typical S&C environment (applied setting), and see how the feedback compared.  We were fortunate that a Gentleman (who is a Powerlifter) attending the clinic brought his personal GymAware, so we took the opportunity to collect some data on the Squat to share.  Below you will see some data sets of bar speed feedback, PK and AVG...
