• How to Analyze Training Load and Monitoring Data?

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).

• Shuttle Run Beep Test Improvement & New Test

Few days ago, I spoke with Cameron Josse, who is Director of Sports Performance at DeFranco’s Gym, regarding simple (or should I say, Minimum Viable Program – MVPr) endurance test for football athletes. I have directed Cameron to the article Testing Endurance for Team Sport Athletes and my Shuttle Run Beep Test. Since we are on the same page...

• To Turf or Not to Turf, That is the Question [Part 2]: Applications

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]

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.

• Netflix Prize and Injury Prediction Prize

The Netflix Prize was an open competition for the best collaborative filtering algorithm to predict user ratings for films, based on previous ratings without any other information about the users or films, i.e. without the users or the films being identified except by numbers assigned for the contest. Which made me think – why don’t the “rich” clubs, such...

• Thoughts on Injury Prediction

In the following article, I am discussing the famous “J” curve in injury prediction, as well as simulate some data to show how that curve is estimated. I also show the distinction between association and prediction, as well as how to make training decisions based on the different costs of committing false positive and false negative errors.

• The Dowry Problem

In this video I am solving the famous dowry problem using the simulation in R. It is interesting to see how we can test the assumptions and heuristic easily with simulations.

• Individualizing Training Using Clustering Algorithms

The goal of this blog post is to present simple solution to “grouping” individuals based on their needs, characteristics and/or goals.
