Running-Based Conditioning for Team Sports – Part 2
By Mladen Jovanovic on 19/09/2012I have touched upon training transfer in the discussion of work capacity. Transfer is defined as: if I improve in doing X how much will I improve in doing Y?

Running-Based Conditioning for Team Sports – Part 1
By Mladen Jovanovic on 17/09/2012There is a recent trend in team sports to completely ditch the running-based conditioning for the sake of performing only small-sided games (SSGs). There have been an over-use of running-based conditioning (i.e. running suicides for 20+min or doing long slow run for 60min) in the recent history and now the pendulum have swung into opposite direction – ditching them…

Dashboard design
By Mladen Jovanovic on 04/09/2012I 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...

Player Monitoring – Team Dashboard
By Mladen Jovanovic on 02/09/2012Player 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).

Repeated Sprint Ability is Overrated? [Part 4]
By Mladen Jovanovic on 02/07/2012I want to finish this article so I can go to vacation with ‘clear head’, and spend my time eating gyros, swimming and playing beach volleyball instead of thinking about RST/RSA/RSS. I am afraid that this article got away from sole RST/RSA/RSS discussion. The things I warned against, besides trying to answer whether RST/RSA is overrated, are the following

Repeated Sprint Ability is Overrated? [Part 2]
By Mladen Jovanovic on 23/06/2012Now when I cleared (or made you more confused about) some things regarding time-motion analysis and total/mean scores (without ranges, frequencies and zones), let’s deal with those most strenuous parts of the game. Defining what is strenuous is also tricky. Sprints, 1500m run, marathon, long jump they are all different in duration but done at maximum ability. They…

By Mladen Jovanovic on 22/06/2012This is going to be an article/research review (rant?) that could be seen as an addendum to my Troubles with RSA I wrote last year. I suggest you check that one first before proceeding with this one.
