Lifespan gets the headlines.
Healthspan gets the abstract.
Marginspan gets ignored... and Nowspan isn't even on the radar.
But it doesn't have to be that way: https://t.co/rtJ2L0HFcQ

@gregorykennedy @UltraRunner26 @In_Sane_Saint It’s just Garmin being nice 😅

[Brad Cooper, PhD @Catalyst2Thrive]

@gregorykennedy @UltraRunner26 @In_Sane_Saint “benefit of the doubt” 😉

[Brad Cooper, PhD @Catalyst2Thrive]

@gregorykennedy @UltraRunner26 @In_Sane_Saint Upgraded to a Forerunner 970 but it still seems to give me the merit of the doubt at age 60

(Haven’t done lab test lately but in reality I’m probably more like high 50’s)

@BrandonLuuMD Would be interesting to peel this out by “highly engaged” / “disengaged” (in work). I love my work so while enjoy vacation, I’m also happy to return to rhythm of life.

@oscarfogelstrm @Brady_H I've done thousands of miles on Tmills over my 60 years. We went w/ it - potentially last one we'll own? - due to smooth feel, options thru app, creative options w/ auto-pace, avail speeds - & maybe most of all -that my @wahoofitness bike trainer has been dependable for 15+ yrs.

Pretty good month considering 15 days in Japan & surprisingly impactful jet lag. Excited to get back into training rhythm through the summer!

[Brad Cooper, PhD @Catalyst2Thrive]

@bbculp @MichaelDBrandt @ketone I was thinking the same 🎯

You have no idea how dialed in your daily fueling plan is until you schedule you colonoscopy 😅

I life’s 2nd half, it’s easy to think “I’m fine (at the moment)” in reference to physical state.

Shifting our view to “what will my optimal 80’s involve?” Adjusts our vision… and the tendency to settle for that 4-letter f-word: “fine.”

Rest doesn't protect the arthritic knee... activity nourishes it and has been proven to result in significant pain relief. And... high-intensity running shows the greatest pain relief. Not intuitive at all...
Don't rest your arthritic knee; you're not protecting anything, and you're throwing your general health under the bus.

If you don't tolerate any load... well-- then it might be time to talk to your surgeon.

Conclusion
The message is the same as before. Carbohydrates win, and fat is not an efficient fuel for high-performance exercise. Yes, you can run a long way at a slow pace on a high-fat diet. For the 0.00001% of people whose entire sporting goal is to finish a 200 km ultramarathon at 5 km/h, the LCHF approach can technically work. For the rest of endurance sport, where pace at threshold determines outcomes and where the difference between fuels shows up in seconds per kilometre, the answer has not changed in a hundred years. Carbohydrate oxidation produces more ATP per litre of oxygen consumed. More ATP per litre of oxygen means more power at the same VO2. More power at the same VO2 means you finish ahead of the keto guy. Noakes can rewrite the historical literature, exclude inconvenient elite-athlete data, and lean on a 10 g/h carbohydrate dose that itself proves his own original LCHF claim wrong, but the stoichiometry does not negotiate.
Carbs win.

@tim_roozendaal There’s a 1 letter difference between “Get to” and “Got to” - but that one letter will change your life (in running but also so many other aspects)

@JWLevitt Anyone NOT have their best ideas while out on solo run? I used to take a little digital recorder w/ me on long runs. Now avail on phone but gold mine!

[Brad Cooper, PhD @Catalyst2Thrive]

@SahilBloom @poetwithpace I’m going to remember that! 🤣🤣

[Brad Cooper, PhD @Catalyst2Thrive]

@SahilBloom @poetwithpace Hmmm… if only an X friend would have mentioned that beforehand 😉😅

Good job!

Very well written, as usual! Thanks for diving in but leaving the scuba gear behind @Brady_H

What makes the 'athlete’s heart' unique?

It’s not just “bigger.” It’s better adapted to the time constraints of exercise.

When heart rate rises, the heart has less time to refill between beats. In endurance athletes, chronic training remodels the heart in a way that helps solve this problem: a larger left ventricle, larger left atrium, and greater filling volume and flow rates (which also explains their lower resting heart rates).

Each beat can pump more blood, and even when heart rate climbs, the athlete’s heart is better able to preserve ventricular filling and sustain a high cardiac output.

Move. Fuel. Rest. Connect.

Four words that cover 95% (plus) of what any health headline is trying to sell you.

Everything else - outside of direct medical & mental health care - is essentially a rounding error.
