  • Optimizing Groups for Small Sided Games (SSGs)

    By Mladen Jovanovic on 23/08/2013

    In the following video I will show you how to: a) Calculate normal scores for any test/statistic (percentiles & z-scores) and the difference between them; b) Calculate composite scores using weighting factors and normal scores; c) Use one great Excel tool – SOLVER to provide optimized solution for groups;

  • Individual Qualities vs Positional Demands

    By Mladen Jovanovic on 14/08/2013

    Individual Qualities vs Positional Demands One frequent question I get from coaches and try to resolve myself is whether the conditioning should be based on individual characteristics (MAS, YOYO, VMAX, etc) OR based on position demands? Regarding the position demands: how do we quantify them and what is the worthwhile difference (SWC) between positions that warrants different training prescription?...

  • Naming the HIT Drills

    By Mladen Jovanovic on 14/08/2013

    I love the idea of naming certain drills/workouts (like Crossfit does using female names) because it is easier for the athlete to ‘personalize’ them and remember them. So, instead of saying we are going to do 30:30 intervals at 100:70% MAS, it might be easier to say “Boys, get ready for Bloody Mary”.

  • 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.

  • Analyzing Time-Series of Individual Data

    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.

  • Some Great Findings and Ideas From Velocity-Based Strength Training

    By Mladen Jovanovic on 07/08/2013

    Some great findings and ideas from velocity-based strength training – I have been thinking more and more about velocity-based lifting recently as a method of prescribing load and volume for an individual. I have wrote couple of blog posts and article on this topic that you might want to read first:

  • Measuring External Workload in Boxing Using Accelerometers

    By Mladen Jovanovic on 02/08/2013

    Measuring External Workload in Boxing Using Accelerometers Few years ago we had a pleasure of using MiniMax GPS devices (two of them) which we got for three months testing by courtesy of Catapult. I was amazed by the simplicity of it’s use and great software that comes with it – Sprint. I have been playing with normal features and...
