DIY CoolSculpting one year on

It’s been a year since I experimented with DIY CoolSculptingto spot reduce abdominal fat, and so I’ve updated my page with details of how the treatment has lasted.

DIY Altitude Training

I've been using an altitude system for some years, and found it quite effective, but it's rather pricy for what it is has some flaws. As a result I've created a DIY system for Altitude Training that should be easy and cheap to build. I've put the details at http://fellrnr.com/wiki/DIY_Altitude_Training so let me know what you think.

Updated SportTracks plugin

I've just released a new version of my plugin, which adds support for two new performance models; the Banister model and Busso's refinement of the Banister model. It still supports the Training Stress Balance model that is a simplification of the Banister model.

Other changes

• Analytics graphing
• Change graphing to be a new view rather than on the reports page
• Add smoothing, including an auto smoothing
• Add option to project performance forward one month
• Improve tool tip (mouse over) text
• The 'force recalculations' now does a full recalculation
• Support normalized TRIMP values
• Use local time for TRIMP calculations
• Better support for TRIMPcr10
• Changes to performance optimization
• More translations for "running"

Models of human performance

I've written up some notes on three mathematical models of human performance; Training Stress Balance, Banister's model and Busso's model. I'm currently adding the latter two into my SportTracks plugin and I hope to release it soon. http://fellrnr.com/wiki/Modeling_Human_Performance

PaleoRunner's podcast interview with Dr Tim Noakes

I recently listened to a podcast interview with Tim Noakes, the famous author, runner, doctor and scientist. I think the podcast is well worth a listen, and I agree with a lot, but not all of Dr. Noakes’ comments. Here’s some thoughts:

• Paleo diet. I don’t know enough about the Paleo diet to comment, but I’m reading a lot about ketogenic diets at the moment. I suspect that Dr. Noakes’ experience with diet are going to get a lot more attention in the future, and there is a lot of validity to his ideas. However, I also suspect that like many areas of exercise and nutrition, there will prove to be a lot more complexity than is apparent.
• Waterlogged. I agree completely with Dr. Noakes that the main cause of ‘water intoxication’ (Exercise Associated Hyponatremia or EAH) is over hydration. This is actually #1 on my list of Top 10 Marathon Racing Mistakes. However, I disagree with his evaluation of the science of hydration and sodium losses at high sweat rates, and believe it is possible to get EAH without over hydration with prolonged exercise at maximum sweat rates. I also believe that it is possible to become sodium deficient in hot conditions.
• Central Governor Theory. I believe Dr. Noakes is right about the Central Governor Theory, and I’ve found some research indicating that exercise in mild heat is not perceived as being too hot, but being fatigued. This is why marathon runners underestimate the impact of heat on marathonperformance.
• Is running bad for you? I enjoyed Dr. Noakes’ perspective on this controversial subject. His interpretation of the limited science seems well balanced and reasonable to me.
