  • Real-Time Fatigue Monitoring using Metabolic Power and CP/W’

    By Mladen Jovanovic on 26/10/2013

    Over the years there were couple of tries to monitor fatigue real-time in team sports, such as soccer. The most simple one was to use heart rate (HR) data and see if the players were getting tired by checking if the HR was getting higher and higher. Long story short – this doesn’t work and I have no clue…

    Over the last month I have been learning R programming language that is completely FREE and used extensively in statistics and data analysis. I have been also playing with ggplot2 which is a great graphics package for R, along with knitr which was used to produce this blog post/report.

  • Analyzing Time-Series of Individual Data – Part2: Using Harmful/Trivial/Beneficial Chances

    By Mladen Jovanovic on 10/08/2013

    Just a quick update – after a comment by John Fitzpatrick (@JFitz138) on the use of Will Hopkins’s approach of calculating chances I decided to give it a shot. For a Typical Error (used together with SWC to calculate chances) I used SD of the Rolling Average.

    If you haven’t been living in a cave for the last couple of years, you definitely noticed an increase in data collection, data mining and visualization. HRV tracking, jump output tracking, estimating 1RMs from velocity-load data, game statistics, performance analysis, various testing statistics, body weight, Run Keeper, Run Tracker, and all that quantified-self movement.

  • Player and Test Report/Dashboard

    By Mladen Jovanovic on 11/11/2012

    During the last couple of weeks I have been reading a lot on VBA (Visual Basic for Applications) for Excel since I haven’t found PivotTable enough to fulfill my needs. Luckily I have a programming background (yup, a nerd – been using Qbasic, C/C++, MATLAB and Assemblerduring the days of 486) so I had the basic skills and all...

    By Mladen Jovanovic on 31/10/2012

    At the moment I am working on an Excel database and dashboard for tracking performance and screening data and creating a player profiles (dashboards). Theoretically, this should help me devise individualized training focus (does this guys need more core work, more mobility, speed, etc… how is he ranking to other guys… did he improved since last testing?). What I...

    By Mladen Jovanovic on 04/09/2012

    I have received quite a few emails on my last blog post.  Most of the authors asked me  how to create the dashboard that conveys clear and simple message to the viewers. Honestly, I am new in this area myself but I can point you to the following two papers by Stephen Few I found a must read: Graph design...

    By Mladen Jovanovic on 02/09/2012

    Player Monitoring – Team Dashboard I have been working lately on summarizing the data we collected and creating one dashboard in Excel (I am going to start using R, because I think I will be able to do more powerful data analysis and visualization and it is free). I use this sheet to store, analyze and visualize the data...

  • Playing With Statistics [Part 5]

    By Mladen Jovanovic on 26/03/2012

    Playing With Statistics Although at the end of part 4 I mentioned I will talk about analysis of frequent tests like sRPE, HRV and other’s that are used for monitoring, I will not do that in this part. Maybe in part 6 because I am still ‘playing~struggling’with that one. What I want to talk today is data...
