  • Three I’s of Intensity in Strength Training

    By Mladen Jovanovic on 23/09/2013

    Coaches, and especially researchers should take into account all three parts of prescribing and quantifying Intensity (Intensity together with Volume provide LOAD; but I will leave different ways of quantifying Volume for another rant) to avoid confusion and provide precision. This could be done with monitoring velocity of the lifts as well and I urge researchers reading this to...

  • UPDATE: Percent-based to velocity-based converter 2.0

    By Mladen Jovanovic on 17/09/2013

    I have updated Percent-based to velocity-based converter to include conversion from velocity-based to percent-based approach using load-velocity profile and %1RM-max reps profile. This is important since it allows coaches to get easier ‘grip’ on velocity-based approach and how it could be used and converted.Here is the screen shot

  • Percent-Based to Velocity-Based Converter 2.0 [Excel Workbook + Video Tutorial]

    By Mladen Jovanovic on 03/09/2013

    “Nothing Is More Practical Than A Good Theory” – In the following video I am explaining how to use Excel converter to convert percent-based programs to velocity-based programs based on lifters load-velocity profile for a given movement.

  • How to Track 1RM Without Actually Testing It?

    By Mladen Jovanovic on 02/09/2013

    Introduction – There are two main methods for estimating 1RM of an exercise: (1) to build up to true 1RM lift and (2) to estimate 1RM from reps-to-(technical)-failure  with sub-max weight using various formulas and tables.

  • Using Absolute vs. Relative Velocity Zones [Random Thoughts on GPS]

    By Mladen Jovanovic on 01/09/2013

    Using Absolute vs. Relative Velocity Zones Suppose you are coaching two distance runners, one with MAS (Maximum Aerobic Speed) of 18km/h and one with MAS of 21 km/h. The former is definitely more aerobically fit and would crush the latter in most middle to long distances (taking into account that threshold is proportional to MAS)....

  • 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

    By Mladen Jovanovic on 09/08/2013

    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.
