  • Few Thoughts on MMA Program Design

    By Mladen Jovanovic on 12/04/2021

    How to design an S&C training program when you are not in charge of the overall plan? In the following video, I am explaining this topic for combat and MMA sport.

  • Designing Strength and Conditioning Programs

    By Mladen Jovanovic on 02/04/2021

    This how-to mini-course is an outstanding example of the “bottoms-up” approach to training design, where one deals with “where the rubber meets the road” constraints, such as facility limitations, equipment availability, team/group logistics, rather than the “top-down” approach of some textbook-style long term periodization.

  • Athlete Monitoring: Data Analysis and Visualization – The dorem package

    By Mladen Jovanovic on 12/03/2021

    Athlete Monitoring: Data Analysis and Visualization The dorem package One of the best and the most practical papers I have read is Clarke & Skiba’s “Rationale and resources for teaching the mathematical modeling of athletic training and performance” (DOI: 10.1152/advan.00078.2011). Ever since reading that paper, I was interested in Banister’s Impulse-Response (IR) model and even wrote few R scripts...

  • Athlete Monitoring: Data Analysis and Visualization – Shiny AthleteSR Dashboard

    By Mladen Jovanovic on 12/03/2021

    Athlete Monitoring: Data Analysis and Visualization Shiny AthleteSR Dashboard In this video, I am walking you through the Shiny AthleteSR Dashboard. As explained in this and the previous video, this course and the athletemonitoring package were the result of my attempt to build this mockup dashboard for the AthleteSR developers. Everything covered in this course is implemented in this...

  • Athlete Monitoring: Data Analysis and Visualization – AthleteSR

    By Mladen Jovanovic on 12/03/2021

    Athlete Monitoring: Data Analysis and Visualization AthleteSR The idea for this course started when I developed an athlete monitoring Shiny dashboard for the AthleteSR, which is our app for athlete management (FREE for the Complementary Training members). The goal was to have a formalized way to analyze and visualize the data for our developers, so they can implement it...

  • Athlete Monitoring: Data Analysis and Visualization – Nominal Analysis

    By Mladen Jovanovic on 12/03/2021

    Athlete Monitoring: Data Analysis and Visualization Nominal Analysis To remind ourselves, nominal analysis is the same as the continuous (i.e., ratio scale) analysis, but with dummy coding, where each level is represented as an additional variable with 0 or 1. Thus, (rolling) proportions and counts are the methods used to analyze and visualize the nominal variables. In this video,...

  • Athlete Monitoring: Data Analysis and Visualization – Continuous Analysis

    By Mladen Jovanovic on 12/03/2021

    Athlete Monitoring: Data Analysis and Visualization Continuous Analysis In this video, I will explain how to use the prepare() function from the athletemonitoring package. This function/package allows us to implement everything we have covered so far in this course: Dealing with missing entries Dealing with missing days Acute and Chronic rolling windows for smoothing and trends Rolling functions Group...

  • Athlete Monitoring: Data Analysis and Visualization – Introducing athletemonitoring R package

    By Mladen Jovanovic on 12/03/2021

    In this module, I am going to introduce athletemonitoring package by demonstrating how easy is to perform common data analysis and deal with issues explained in the previous modules. I will also demonstrate the AthleteSR software, how to extract/sync the monitoring data from it and how to analyze it.

  • Validity and Repeatability of the YoYoIR1 and 1000TT: Re-analysis of the Clancy et al. paper

    By Mladen Jovanovic on 25/02/2021

    In the following two videos and a PDF report, I am going to re-analyze the paper by Clancy et al. using bootstrap magnitude-based approach (using bmbstats package) and mixed-effects model in R language.

  • Athlete Monitoring: Data Analysis and Visualization – Basic Visualizations

    By Mladen Jovanovic on 19/02/2021

    Athlete Monitoring: Data Analysis and Visualization Basic Visualizations In this video I will show you the basics of visualizations using ggplot2 package in R. GGplot2 package is the implementation of the Grammar of Graphics – a general scheme for data visualization which breaks up graphs into semantic components such as scales and layers. I am demonstrating the very basic...
