Visualization, Adrenaline and Sleep Problems

Visualization is amazing; there's no question about it. And there is a phenomenal amount of information available about visualization on the internet (Google "visualization" and you get 19.3 million hits). However, there seems to be absolutely no information about a crucial way in which visualization can go bad. It can steal your sleep. As you… Continue reading Visualization, Adrenaline and Sleep Problems

Swimming By the Numbers: How Elite Men Swim the 200 Butterfly

This time up: 200 Butterfly for Men. The first set of analyses involved the long axis strokes for men and women (here, here and here). We found clear indications of specific race profiles (Sprinter, Distance and Hybrid - see below) that made sense given the efficient nature of the strokes. The women's freestyle and backstroke… Continue reading Swimming By the Numbers: How Elite Men Swim the 200 Butterfly

Wandering Minds, Unhappiness, and Lack of Improvement

I was driving home today, listening to a TED Talk Radio Hour podcast called Simply Happy. One of the speakers, Matt Killingsworth, has spent years studying happiness as part of his Ph.D. research at Harvard, and this includes a project involving 35,000 interactions with participants (see here).

Swimming By the Numbers: How Elite Swimmers Swim the 200 Free

I've long wondered about the strategies elite swimmers use for the 200s. It is perhaps the toughest distance to swim, as it involves a good mix of sprint speed and endurance. I've wondered as to how hard they take it out, or how hard the middle 100 should be? Are there appreciable differences between how… Continue reading Swimming By the Numbers: How Elite Swimmers Swim the 200 Free

Swimming By the Numbers: The Unfairness of Short Course – Long Course Conversion Rates, especially for Backstrokers!

I'll start off with the teaser. Existing one-size-fits-all course conversion rates are not remotely accurate, especially for backstroke, and there exists a sizable difference in accurate conversion rates between men and women. Finally, any swim governing body that uses a single, artificially low conversion rate is doing a great disservice to its members. Now, on… Continue reading Swimming By the Numbers: The Unfairness of Short Course – Long Course Conversion Rates, especially for Backstrokers!
