Strength Card Builder 1.1Because of the interest, I decided to modify and update my Excel workbook I have been using for creating strength programs for groups and individuals. In the video below you can see all the features of this workbook. One of the key features is the ability to create GROUP workout cards based on players 1RMs in core/key exercises, along with writing your own set & rep schemes.This product is not available any more. Please look for the new vers...

Optimizing groups for Small Sided Games (SSGs)In the following video I will show you how toCalculate normal scores for any test/statistic (percentiles & z-scores) and the difference between themCalculate composite scores using weighting factors and normal scoresUse one great Excel tool – SOLVER to provide optimized solution for groupsThe rationale behind this approach is that we want groups of players that are balanced in some way (we decide based on what parameters). In the video below I have used skill rating and MAS score, but you can easily...

Individual Qualities vs Positional DemandsOne 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? Most of the studies focused on p values instead of SWC and TE. Speaking of TE (Typical Error) there is a huge %CV (coefficient of variation)...
Naming the HIT drillsI 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”. In the table below I have presented couple of HIT variations, including SIT (Sprint Interval Training, a.k.a Anaerobic Power/Capacity)...

Analyzing Time-Series of Individual Data #2: Using Harmful/Trivial/Beneficial chancesJust 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. To calculate chances I have coded simple VBA function that use NORM.DIST function of Excel. To calculate...

Analyzing Time-Series of Individual DataIf 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. Collecting data is getting easier and easier – even without one being aware of it. What is still falling behind is making sense of...

Some great findings and ideas from velocity-based strength trainingI 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: Estimating 1RM using load-velocity relationshipVelocity Loss as an Indicator of Neuromuscular Fatigue during Resistance TrainingVelocity-based strength...

For the last month we are having a pleasure of using MiniMax GPS devices (two of them) which we got for three months testing by courtesy of Catapult. I am short of amazed by the simplicity of it’s use and great software that comes with it – Sprint. I have been playing with normal features and uses of Catapult GPS, but my wild (or weird?) spirit won’t let me alone so I wanted to experiment a bit with the units and software while we have them...
