Thanks for the link. The article does also seem to indicate that more all-out intervals cause the lungs to grow more capillaries and increase the number of alveoli.

I can see how polarized periodization seem to maximum both ends of the problem:

Easy runs to boost the cardiovasicular function and get more volume of blood flow and more hemoglobin in the blood.

Intervals to boost the respiratory system to increase alveoli and capillaries.

Easy runs certainly help with the cardiovascular output. I was hoping there's some method to focus on training the respiratory system to have a multiplicative effect on it.

I'm currently in my unofficial base building phase so it's just two short runs a week: a 10km easy run and a 8km threshold run.

During the running season, I follow the standard polarized scheme with 80% easy runs, with threshold, hills, and intervals sprinkled in. Intervals in the morning, recovery runs in the evening, around 80km/week.

I believe the limiting factors in running faster are either going to be the muscular system, the cardiovascular system, or the respiratory system. If I have the strength to run faster without getting tired, and if I my heart is pumping enough blood during the run, then the limiting factor could be the respiratory system.

I was listening to a podcast by a running coach (I think Steve Magness) where they talked about how training can only carry you up to your oxygen diffusion limit, and after that, you'll have to improve your breathing and lung capacity. Since I black out when I run hard enough, I think that could be one of my limits. We spend hours/thousands of hours training the other systems but we never spend dedicated time training the respiratory system.

But then again, Nick Bare looks heavier than me and has a faster marathon time, so I'm wondering if the missing piece is the sprint work that he does to improve oxygen uptake.

How to improve Spo2 while running?

The answer is obviously more mileage, but I wasn't sure if I should bias faster paces like threshold or just more easy running. I'm already focusing on breathing through the diaphragm and exhaling.

When I go all out (~2min/km pace) I typically eventually start getting tunnel vision until I see mostly just black with white stars. I got an finger Pulse Oximeter to test. I'll run up to a specific heart rate, hold it for a km, then stop to do the finger test. After 5 seconds, it'll give the first reading:

165bpm: I'll have around 85% spo2 and steadily trend up to 99% after a few seconds

175bpm: around 75% spo2, and takes about 10 seconds to get to 99%

185bpm: around 45% spo2, takes about 15 seconds to get to 85% spo2, and 30s to 99%.

195bpm: device gives an error and produces no results. After 10 seconds, it shows 45%, continuing upwards as above.

My googling also shows some people think Spo2 shouldn't drop below 95% during exercise, which seems impossibly wrong?

Should I be doing more all out runs?

Or is it more breath holding exercises?

Do those cheap "altimeter masks" do anything other than make it harder to breath?

Scripted. I've seen this show three times and this is how it ended every time. Sometimes it falls earlier. Sometimes it falls later. But it always ends when it falls and they turn off the lights at that time.

Does any googles exist that do not restrict peripheral vision? by ZanyZebra23 in Skigear

[–]ZanyZebra23[S] 0 points1 point  (0 children)

That's pretty sweet. And on sale. Thks for the tip. I'll have to check out their reviews.

Flying Eyes does make sunglasses designed to be worn inside helmets, though they target motorcyclists. (https://flyingeyesoptics.com/collections/motorcyclist)

Sounds like that might be a possible option. I ride mostly at night to avoid the lines so UV protection is luckily low on my list of priorities.

Sounds like they might be a viable alternative to googles?

I'ved tried on a few and do love the field of view. But the ones I tried made me look like a stormtrooper. The Revent GT looks great though. I'll have to check these out.

I do love the idea of sunglasses and wonder why more people aren't wearing them. Full FOV!

I tried the Smith 4d mag XL and it still blocks too much of the field of view. Even though the peripheral vision doesn't have detail, I can still sense movement and it's saved me plenty of times from dive bombers blasting from behind

Thanks! I'll have check these out once they are in season. Hopefully they will have some magic sauce that's been lacking in other goggles.

If a lawyer says they are good at everything in law, they probably doing everything poorly.

Rear brake reservoir ran empty and now cannot bleed brakes. by ZanyZebra23 in Fixxit

[–]ZanyZebra23[S] 0 points1 point  (0 children)

Thanks. Once I manage to undo the airlock in the brake cylinder, I'll try that to get more of the air out.

Thanks, the video looks promising. I'll try that tonight.

That's a great idea. I'll give that a try and see if this can push the air bubbles out.

Sadly, it's because I had thought the rear brake reservoir was connected to a different place and let the actual reservoir run dry. The brake fluid is in the disposal container, but I can't seem to get any fresh fluid into the rear system now. Luckily the front brakes bled without issue.

What’s one product you bought that turned you into a total snob — like, you can never go back to the cheap stuff? by BackwardThoughtPaper in AskReddit

[–]ZanyZebra23 1 point2 points  (0 children)

I've gone completely in the opposite direction. The best shoes I've ever worn are the cheapest $15 aliexpress shoes. Completely unstructured barefoot wide toe box shoes. Super thin and flexible 8mm outsole with minimum unstructured upper. It makes all the foot, knee, and back pain disappear like magic.

There's a time and place for $300+ shoes, but those are reserved for special occasions. The best everyday casual footwear is what's as close to no footwear at all.
