We have all seen it.  A great athlete has a chance to win a championship.  All that is required for them to do something they have done hundreds of times before…sink a 3 foot putt, make a free throw, kick a 20 year field goal. And they miss!  In this episode I explore the fascinating topic of choking under pressure. Why do some athletes excel in these situations while others fail?  What causes choking and want can an athlete do to prevent it?

This past Friday one of my personal favorite sporting events kicked off…the Rugby World Cup.  The NFL Football season is also of course now in full swing.  So, which sport has the bigger hits: football or rugby?

Is the claim that visual training can “improve vision” deceptive and worthy of a $150K fine from the FTC?  Can we say that the benefits of visual training will transfer to sports performance?

Hi Everyone,

HeadTrainer is one the newest applications in the continually growing market of perceptual-cognitive training products for athletes. One of the most striking things about this app is the budget behind it – the production values are at the level of many video games and the company has a team of pretty high profile celebrity endorsers including racecar driver Dale Ernhardt Jr, baseball player Jose Bautista, surfer Alana Blanchard and golfer Rickie Folwer. The program (which costs $4.99/month for the full edition) includes exercises designed to improve decision making, processing speed, focus, visual-spatial awareness and memory. But does it work?!

Well, I have signed up!  So, over the next few weeks I am going to look more closely at the science behind this product AND give regular updates on my progress through the training. I will also be giving an analysis of the contents of the training as an alleged expert in this area J Finally, I will be doing pre and post sports related skills tests to see if there is any transfer effect to my performance.  So, I am basically doing a single subject, pre-post case study on myself. Not exactly rigorous scientifically but it should be fun and give me a chance to embarrass myself.  

So keep watching this space for blog posts, videos and podcast segments as I attempt to train my head!

Cheers,

 

Rob

How long do athletes retain the sports skills they learn: 5 years, 10 years, forever?  If they do lose something, what is it?  How easy is it to transfer from one sport to another?  What factors determine whether or not transfer will be successful?  This episode explores the topic of retention and transfer of sports skills.

Did Serena Williams choke under pressure in her historical US Open loss? 

Is virtual reality training going to revolutionize quarterback play? It certainly doesn't seem to be working for Auburn's Jeremy Johnson.

Pro Move Mini Motion Tracking System Review

http://inertia-technology.com/promove-mini

 Note: the images and data plots are meant to accompany the review in Episode 9, Time Code 18:21

Fig1

Test 1: One sensor, linear motion

-plots are acceleration data for me attempting to do 3 slow movements followed by 3 fast movements constrained to one axis. (Note, I did not use any kind of frame to constrain movements so there will be some cross talk Data are filtered with a second-order Butterworth frequency of 20 Hz.

Fig2

Test 2: One sensor, rotation

-same as Test #1 except rotating about 1 axis

Fig3

Test 3: Two sensors

-Holding one sensor in each hand.  In-phase motion in first half, anti-phase in second half

How do we know how well a new training program or piece of sports equipment is working?  Is looking at how performance changes in practice (by plotting a "learning curve") really the best way to assess skill acquisition. No, no it isn’t.  In this episode I make the case for going off the learning curve in favor of other ways of measuring skill learning in sport.
