  • AFL Game GPS Stats Analytics Workbook

    By Mladen Jovanovic on 14/03/2015

    Keith Lyons shared one game of data for one AFL game across four quarters for the #UCSIA15 course. I took some time to analyze it using R and created interactive and reproducible document (HTML) using knitr and markdown. You can download markdown file and CSV data file HERE

  • Training Stress Balance Workbook Con’t

    By Mladen Jovanovic on 12/03/2015

    In the previous video I was talking about two different methods of calculating Training Stress Balance and underlying assumptions. In this short addendum I will explain even better method of calculating TSB by combining good parts of previous two, discuss differences between calculus of TSB for “daily data” (e.g. training load) versus “occasional data” (e.g. HRV, readiness metrics) and…

  • Training Stress Balance: Two Methods of Calculation and Assumptions

    By Mladen Jovanovic on 07/03/2015

    In this blog post I will share with you the Excel workbook you can play with, and also the screen cast of me explain how to use the TSB method. I am also discussing different pro’s and con’s of two very similar ways of calculating Chronic and Acute Load and their assumptions.

  • How to Easily Make Sense of Your Training Load Data Using TSB

    By Mladen Jovanovic on 02/03/2015

    Training Stress Balance (TSB) is a concept I first heard of in Training and Racing with Power Meter by Allen and Coggan in 2010 and I immediately found it very interesting and tried to implementing couple of times. Learn how to implement it in this article.

  • GPS Training in Team Sports – Implications for Coaching

    By Mladen Jovanovic on 13/02/2015

    On Friday, 27th March I will be giving a webinar on GPS use in team sports at Brendan Chaplin’s “Meeting of the Minds” 2015 Conference. I have written a bit on making sense on GPS data, but in this webinar I plan expanding further and covering things such as: Drills classification using clustering algorithms Use of absolute vs. relative...

  • Reconciling Sheiko and Westside

    By Mladen Jovanovic on 05/02/2015

    Sheiko and Westside are probably the two most know powerlifting training systems that brought numerous champs in the sport. Yet, they tend to differ a lot. The question is who is right?

  • On Reading… and Fear

    By Mladen Jovanovic on 30/01/2015

    On Reading… and Fear Here is a thought to consider: we buy and read books not in a hope we will learn something new, but in fear we will not learn something new and useful otherwise. We check what others are reading, and we might buy and read in fear we will be missing something others won’t. Please note...

  • Periodization Confusion? Full Video From Windsprint Conference

    By Mladen Jovanovic on 25/01/2015

    Periodization Confusion? Full Video From Windsprint Conference As you probably know, I gave a presentation on reconciling periodization/training “confusions” at Windsprint (organized by Håkan Andersson). The slides are available for some time (LINK), but I recently got the videos so I decided to make them available for the members. Please note that this presentation is my first overall and...

  • Effect of Typical Variation of a Test on Confidence Interval

    By Mladen Jovanovic on 20/01/2015

    Confidence intervals gives us the range of a given statistic when generalizing from a sample to a population. The simplest example could be mean of a sample (e.g. average height) – what we are interested in are the generalizations (or inferences) from this sample to a population (e.g. average height in population). Due the sampling error we are not…

  • Four Important Complementary Pairs

    By Mladen Jovanovic on 15/01/2015

    Four Important Complementary Pairs I believe that there are four important complementary aspects in training (and performance) theory (and reality). Understanding these four aspects can yield many dividends in your training philosophy and help you understand, or better yet, reconcile what seems to be paradoxes and dichotomizations of the training and performance. Skill~Ability Physical~Cognitive Goal~Method Sharpen~Saw (or Develop~Express) I...
