What does this mean? It means that the score (maximum aerobic speed) reached in the COD corrected beep test can now be used in both long distance and shuttle based conditioning. The shuttle run beep tests so far didn’t implement corrections for CODs, and have used exact beeps from straight line version of the test , which resulted in...

In this video I am presenting my “solution” to the problem and provide fake data set, as well as R code for analyzing the data. Having decent predictive model can help us run different optimization algorithms to find the “best” scheduling to minimize/maximize injury risk or performance.

I was asked by Rod Whiteley and Nicol van Dyk to contribute to the Aspetar Journal targeted topic issue that just got released off the press. I tried to combine my knowledge of predictive analytics, machine learning, philosophy of science, heuristics and practical experience as coach & sport scientist into one article. Hopefully I managed to create readable narrative.

I decided to create a course for sport scientists, to get you started with PowerBI. My bet is that PowerBI will become new Excel (if not already) and having the skills needed to produce reports will be needed as Excel skills are needed now. So, knowing how to learn PowerBI will put you ahead of the curve and...

Predicting Injuries Using Banister Model – The Addendum A year ago I tried to use Banister model to predict injuries, but I recently realized I made an error implementing link function. So, I decided to do one more try and correct the problem. In the video below I am using three training load metrics (RPE Load, Odometer and High...

Homoeostasis Performance Model is a synthesis between Noakes’s Central Governor Model and Schmidt’s Conceptual Model of Human Performance. Some of the Bernstein’s conclusions about motor controler, who controls human movement, were: 1) Control system is hierarchycally organized on couple of levels; 2) There is a feed-back that connects lower parts with higher parts of control system, which is used...
