  • Shuttle Run Beep Test with COD Corrections

    By Mladen Jovanovic on 05/08/2017

    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...

  • To Turf or Not to Turf, That is the Question [Part 2]: Applications

    By Mladen Jovanovic on 26/07/2017

    In this video I am deploying the model to make the decision between 5 variations of weekly plan. The goal is to minimize the morning soreness on the day of the game.

  • To Turf or Not to Turf, That is the Question [Part 1]

    By Mladen Jovanovic on 05/07/2017

    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.

  • Netflix Prize and Injury Prediction Prize

    By Mladen Jovanovic on 13/03/2017

    The Netflix Prize was an open competition for the best collaborative filtering algorithm to predict user ratings for films, based on previous ratings without any other information about the users or films, i.e. without the users or the films being identified except by numbers assigned for the contest. Which made me think – why don’t the “rich” clubs, such...

  • Uncertainty, Heuristics and Injury Prediction

    By Mladen Jovanovic on 07/03/2017

    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.

  • Power BI Course for Sport Scientists – Video 1

    By Mladen Jovanovic on 04/03/2017

    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...

    I had the pleasure to interview Cristian Osgnach, who is one of the leading researchers and pioneers of Metabolic Power concept, as well as involved in GPEXE project, which is 20Hz GPS performance monitor & analytical system for professional sports. Enyoj!

  • Predicting Injuries Using Banister Model – The Addendum

    By Mladen Jovanovic on 14/10/2016

    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

    By Mladen Jovanovic on 03/07/2016

    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...
