@tim_roozendaal It doesn’t need your weight because running itself already normalizes for weight (everybody must carry their own body weight while running). By contrast a bike test that looked at avg wattage for 12 min would need to be normalized by weight

@esrtweet My theory is not a smoking gun; rather, overweight has gradually become normalized over time, so overweight ppl feel less “out of place” than they would have in the past. Will be interesting to see if Ozempic can reverse this trend

@SitkoSebastian Your recommendations for body fat are way too low. Chris Froome was 10% body fat on DEXA three weeks after winning TdF in 2015

@feelthebyrn1 Re: “My lipid numbers looked a little better when I was training higher volume,” this could also simply be that you were younger then. A lot of people will see a rise in lipids as they age (I certainly did). In any case your numbers are great for no meds!

@feelthebyrn1 There’s a lot of individual variation. I tried cutting saturated fats way down for six months, didn’t make a difference. Going on statins + ezetimibe took my LDL from 180-200 down to 50-60, apoB from 100+ down to 50. I’ll take it for 10 bucks a month

@feelthebyrn1 Are you on any lipid lowering meds? If not those are really good levels. My apob and ldlc are lower, but only thanks to meds

@hybridathlete8 So impressive with ur strength! Interesting to see your running times (esp. mile) and how they correspond to ur VO2max. I just bike, and my 5min power of 401w gives estimate of 58 VO2max. But I don’t have ur strength :( Otoh, I’m 58yo :D

@markisbpm Hey Markis!

@StephenSeiler I have had a good experience with the Wahoo Kickr Bike, 12-15 hr/wk for 2.5 yrs, still going strong and zero maintenance.

@lucasaganronald @NaichacaCycling @CyclingGraphs Superb thread, thanks so much!

@jwhitfie I have been using the Wahoo Kickr Bike for 2.5 yrs, have only used the app to set the drivetrain emulator etc. I didn’t even know you could do a workout in there. Presumably most users use other apps for workouts

@feelthebyrn1 My sense from my own test is the most important data is simply the daily burn at top. I want to believe that is true gold-standard. The other data (BMR, body comp, cause of weight change over test period) are not so reliable.

@feelthebyrn1 @calorify_health As you know the test is expensive, so I wanted to choose a “typical” loading week to serve as a baseline. They calculated my BMR as 1793 cal, so PAL was 2.93, and they said I could keep this up for 139 days before falling apart :D (57yo) Recovery obv is key

@feelthebyrn1 @calorify_health Yes, it was about 12,000 kJ, mostly ez endurance, one VO2 session and one sweet spot

@feelthebyrn1 For VO2max population reference values, I’d prefer this recent German study of 10,000 subjects on cycle ergometer. In particular, see the section at the end where they discuss other studies.

@feelthebyrn1 @EliasLehtonen Interesting that your VO2max on the bike and run were so close. I had heard that running would be higher because of more musculature involved, but perhaps not if you train both disciplines regularly?

@whennotcycling 14,000kJ/wk at your weight is astounding. My best weeks are a little over 12,000 on 15hr/wk recently, 5days on/2 off. Considering adding a 6th day ez to try to get 17hr/wk. (87kg, 57yo)

@DrTEHughes @jem_arnold BLa is interesting to look at a couple times a yr, but measurements are quite disruptive to the session. Day in, day out, I find HRM much more useful and indispensable.
