Variable Clustering and Archetypal AnalysisBy Mladen Jovanovic on 08/05/2018
I believe that the following video and the accompanying R code and data set will be very useful to sport scientists out there and will teach them extremely pragmatic technique in data mining.0
Fantastic Sport Analytics Papers & ResourcesBy Mladen Jovanovic on 03/03/2018
I have recently stumbled on a few great papers that outline very useful statistical techniques, that are VERY applicable to sport and training analytics. If you are interested in analytics, this is a gold mine.
Few Simple Improvements to Monitoring Data AnalysisBy Mladen Jovanovic on 22/02/2018
Most of us are collecting and analyzing training load data and readiness metrics (i.e. GPS training load, sRPE and wellness). The most common analysis method is to use two rolling averages windows – acute (around 7 days) and chronic (around 28 days) and to calculate their ratio, referred to as ACWR (Acute to Chronic Workload Ratio), or TSB (Training...
Why The Concept of Biomotor Abilities is BullshitBy Mladen Jovanovic on 23/01/2018
In my opinion, biomotor abilities are ‘dimension reduction’ of the complex perceptual-motor space. Suppose we perform 500 various tests of performance for at least 5000 athletes.
How to Analyze Training Load and Monitoring Data?By Mladen Jovanovic on 21/11/2017
In this video I am explaining two methods to deal with missing values and why you should pay attention to the way you are aggregating data (daily, team averages, body soreness, etc).
So you can predict the future… But can you change it?By Mladen Jovanovic on 11/10/2017
I also love to call this problem “Terminator Problem”, since it is more understandable to coaches, since most of them have seen Terminator movies. The issue is, once we are able to “predict” the future (for example estimating injury likelihood in the next 7 days), can we actually change it?
Latest on Load Monitoring [Video & FREE Templates]By Sean Williams on 28/09/2017
Sean Williams was kind enough to provide short review of the recent load monitoring workshop, held at the World Rugby Science Network Conference, as well as to provide full slides and Excel templates. This is tremendous resource for those interested in injury prediction analytics.
Novel Strength Metric: Video interview with Robert FrederickBy Mladen Jovanovic on 10/09/2017
I stumbled on Robert Frederic by accident, probably through Facebook. So, after exchanging few messages with him, I decided to do a video interview and a Q&A regarding the “exertion load” metric, as well as his app. We have also touched a bit on Velocity Based Training concepts. Enjoy this video and please leave your comments and questions on...
To Turf or Not to Turf, That is the Question [Part 2]: ApplicationsBy Mladen Jovanovic on 26/07/2017
In this video I am deploying the model to make the decision between 5 variations of weekly plan. The goal is to minimize the morning soreness on the day of the game.
To Turf or Not to Turf, That is the Question [Part 1]By Mladen Jovanovic on 05/07/2017
In this video I am presenting my “solution” to the problem and provide fake data set, as well as R code for analyzing the data. Having decent predictive model can help us run different optimization algorithms to find the “best” scheduling to minimize/maximize injury risk or performance.
