What About CrossFit
I am a 66 year old male doing intense CrossFit training five days per week. I hear you always discussing your zone 2 training and I have wanted to try it, but not yet. I see from my heart rate monitor that I am constantly going between zone 1 and 5 in the same workout, up and down, all over the place. I workout about 10 hours per week (I also cycle outside). I am 5' 10", 172 lbs, body fat today at 11.2%. In 2021 I made it to the CrossFit Games so I am not exaggerating about what I do. Anyway, I have been listening to you for a few years, recently signed up for a membership, and I would like to know your feelings about CrossFit. Thanks.
Low bloodsugar and diabetes 1
Hi! I listened to the AMA episode on glucose where the conclusion was that for non-diabetic 1 patients, the lower the average blood glucose level the better. Why does this not apply for D1s? I know that in D1 the pancreas stops making insulin, but does also the liver stop making and releasing glucose when needed? So diabetes 1 is not only the lack of insulin, but also lack of the liver´s ability to supply glucose when needed?
POWERbreathe and breath training more generally
NPR just covered (link below) a new study on breathe training and its positive effects on blood pressure, respiratory heath and performance more generally. The devices seem rather inexpensive at around $30-60 at the low end and it got me wondering if this is something you've seen and what benefits breath training with this or other devices could have for longevity. https://www.npr.org/sections/health-shots/2022/09/20/1123500781/daily-breath-training-can-work-as-well-as-medicine-to-reduce-high-blood-pressure
Arm elevation affects blood pressure measurement
I frequently test my blood pressure at home with an Omron digital BP device. I follow standard recommendations to keep the cuff at the same height as the heart, etc. Yet, when I go to the doctor, it's common that they let my arm hang straight down. My results are significantly different. Does arm position matter? Should it?
