Training Chats with Israel and Mladen - Episode #2: Evidence Based Practice

June 16, 2018

In Episode #2 of Training Chats with Israel and Mladen, we continued our discussion on evidence based practice. Israel covered some of the history behind the term and movement, and shared his thoughts as to how it can be used in our profession. We spoke about combining evidence from scientific literature, our expertise and experience, current context and athlete preferences to make the best (or least worst) decisions with our clients. Mladen spoke about decision making in uncertainty, different branches of rationality (bounded and unbounded) and how one can use heuristics and ‘barbell strategy’ to make decisions in uncertain conditions.

Books mentioned in this episode:

  1. The Book Of Why - Jude Pearl
  2. Statistical Rethinking - Richard McElreath
  3. Philosophy of Evidence Based Medicine - Jeremy Howick



Training Chats with Israel and Mladen - Episode #1: Introduction

June 3, 2018

Israel Halperin and myself are starting a new series of podcasts covering coaching, training, and sport science while emphasizing the complexity and uncertainty involved in the exercise professions. We plan on publishing 30-40 min episodes every two weeks on various topics and hopefully host different experts and coaches.

In today’s episode we covered the idea behind the project and free flowed a bit. We also covered Israel’s background, how he plans his Muay Thai sessions (from uncertainty perspective), and began discussing the possible problems associated with placing too much confidence in scientific outputs. We agreed that the focus of the next episode will deal with Evidence-Based Practice. Stay tuned.

Beep Test 20m with COD Correction - Audio Sample

August 5, 2017

IT IS FINALLY HERE – The Shuttle Run Beep Test with COD (changes of direction) corrections!

What does this mean?

It means that the score (MAS, or maximum aerobic speed) reached in the COD corrected beep test can now be used in both long distance and shuttle based conditioning.

The shuttle run beep tests so far didn’t implement corrections for CODs, and have used exact beeps from straight line version of the test (UMTT or VamEval), which resulted in lower MAS score.

Complementary Training Podcast #11: Interview with Israel Halperin

December 20, 2016

In episode eleven of Complementary Training Podcast I am talking to Israel Halperin. Israel is a PhD candidate and Muay Thai coach from Tel-Aviv, Israel, who I’ve met in Canberra while he was with Australian Institute of Sport.

Israel is someone with the skin in the game, to paraphrase Nassim Taleb. Someone who has walked the walk as a Muay Thai fighter, and continues to do so by training competitive athletes in Muay Thai and Boxing, as well as doing his PhD. Hence, he is the guy who can talk two languages – coach language and researcher language. I believe his is a true gem in this field.

In the following episode, we have discussed numerous topics, ranging from agile periodization, confounders in training research, dealing with uncertainty and many others. The format was more of a casual chat of two friends, which we are, rather than an interview. I am pretty sure it will make you think.

Before we switch to the chat with Israel, I want to thank our sponsor Smartabase for making this episode possible. Enjoy the listening.

You can reach Israel through his twitter @Israel_Halperin and through his Research Gate.


Complementary Training Podcast #10: Interview with Sam Robertson

September 28, 2016

In episode ten of Complementary Training Podcast I am talking to Sam Robertson. Sam is Senior Research Fellow at Western Bulldogs (AFL) & Victoria University.

We touched about the role of machine learning/predictive analytics in sports (especially injury prediction), “novel” techniques, and how to establish data/sport science department.

Sam is a true leader in the field and someone that has the “skin in the game”– working in a high profile AFL club as data scientist. So I highly recommend listening to this podcast if the topic of data science and data driven decision making is of your interest.

Sam can be contacted through his Twitter @Robertson_SJ



Complementary Training Podcast #9: Interview with John Kiely

September 14, 2016

In episode nine of Complementary Training Podcast I am talking to John Kiely. John is mostly famous for his critiques of periodization (which are a must read papers), so I used this opportunity to expand on that particular topic.

Here are some must read articles from John:

  1. Periodization, Planning, Prediction: And why the future ain't what it used to be!
  2. Periodization Paradigms in the 21st Century: Evidence-Led or Tradition-Driven?
  3. New Horizons for the Methodology and Physiology of Training Periodization: Block Periodization, New Horizon or a False Dawn? [1]
  4. New horizons for the methodology and physiology of training periodization: Block periodization: New horizon or a false dawn? [2]
  5. MINI REVIEW Uniqueness of Human Running Coordination: The Integration of Modern and Ancient Evolutionary Innovations
  6. A genetic-based algorithm for personalized resistance-training
  7. Essay: A New Understanding of Stress and the Implications for Our Cultural Training Paradigm

We have covered a lot of ground in this podcast! If there are any topics you want John to cover in more detail, let us know and we will expand on it. He can be reached via his Twitter @simplysportssci.

I highly recommend following John if you are interested in up-to-date sport science information.



Complementary Training Podcast #8: Interview with Samuele Marcora

August 31, 2016

In episode eight of Complementary Training Podcast I am talking to Samuele Marcora. Samuele is a Professor at the University of Kent, investigating the role of mind/brain in endurance performance, fatigue and physical activity.

This is a pretty long episode, but full of actionable insights. Some of the topics we are covering are the following:

  1. Different models of performance/fatigue – The end of “brainless” physiology?
  2. The difference between sense of effort and sense of exertion/exhaustion?
  3. The basis of psychobiological model of performance/fatigue and it’s distinction to Noakes/Tucker Central Governor model?
  4. Can both models be right? Conscious motivational intensity theory vs. subconscious regulation
  5. Different constraints at work (volitional/motivational – subconscious – peripheral): e.g. 30sec Wingate, TT in the heat, 80% pVO2max to exhaustion
  6. What is mental fatigue?
  7. The role of mental fatigue in team sports? How to assess it and how to minimize it?
  8. Suggested reading for S&C/Sport scientists

So definitely worth your time if you are interested in the novel research on fatigue and its application in real life settings. Samuele shared novel findings on mental fatigue research and its application in training, especially team sports.

Samuele can be find on Twitter @SamueleMarcora and Research Gate.



Complementary Training Podcast #7: Interview with John Lythe

August 10, 2016

In episode seven of the Complementary Training podcast, I am talking to John Lythe.

I can call John my big brother. He was more than helpful with his support and advice from sport science, Excel to personal/life issues. I am really lucky to know this lad. We finally met in person when I was in Doha in 2014/2015. You do not know a person until you drink couple of pints with them. As most of you know John is Excel and sport science wizzard. I've used this interview to pick his brain on numerous topics. 

Here are some of the questions:

  • Why did you start ExcelTrick4Sport?
  • How important is data literacy for S&C coaches and sport scientists?
  • Issues in data driven management?
  • New technologies: R, Python, PowerBI, Tableau – what would you recommend learning?
  • What are the current projects you are working on?
  • Suggested material for interested listeners?

John can be found on Twitter @athletefitness and at his website Also, make sure to check out his YouTube channel.



Complementary Training Podcast #6 - Interview with Marco Altini

July 27, 2016

In episode six of the Complementary Training podcast, I am talking to Marco Altini, the creator of HRV4Training app and machine learning expert. Marco provided tremendous guidelines for my recent injury prediction model and have motivated me to learn more about Bayesian models. Marco also posts regularly on the topics of HRV, machine learning and tracking data.

In this episode we are covering the following topics:

  • How did Marco ended up making HRV4Training and being generally interested in HRV and self-tracking data
  • Reliability of using iPhone camera to track HRV
  • Evaluation of HRV signal
  • Measuring positions, saturation issues, routines, frequency of HRV measurement
  • Training recommendations based on HRV data, and why it is not good to jump to day-to-day twitches in the data
  • HRV as part of overall monitoring system – or the importance of context
  • Machine learning versus traditional statistics
  • Marco’s recommendations for good sources of informations and book
