@Dan_Nash94 @reallyoptimized I don’t run at those speeds. I use a 5% grade.

@Go1MoreMile @reallyoptimized Yes, in the linked podcast we discuss the Randstad 3x13x(30:15). I have played around with this sort of session (200s of 15s). For me personally, I didn't find it very effective at getting my HR up. My max speed is poor and so I find running at these fast speeds muscularly...

A thread on designing intervals to improve VO2max 🧵 (TL;DR, most people go too short and too hard)

@jerryteixeira @JoseAntonioPhD We also need to consider the exercise benefit at 5-7 hrs. We know after 7 hrs it’s diminishing returns, but imagine most weight loss people did 5 hrs consistently? The health and quality of life benefits even without continued weight loss is huge.

@JoseAntonioPhD @Go1MoreMile 7ish hours is where I am at without factoring in 5-6 hours a week of jiu jitsu The trick, if there is one, I just sticking with exercise long enough to start actually liking it. Most people never get past the hating it stage

The more you exercise, the more weight and fat you lose. Holy smokes. What does the “exercise doesn’t promote fat/weight loss” crowd have to say?

@Dan_Nash94 @reallyoptimized But to your point, volume loading builds the heart but a bit more intensity likely builds it best. CO is the key driver of vo2 max.

@Dan_Nash94 @reallyoptimized Have you considered the role of very short SIT with equal rest? Ie 10sec/10sec done for 40-50 x. Christensen demonstrated this in 1960 so I played with it in my lab. Effort and lactate remains relatively low (RPE 13/6; blc 4). Lots of time at vo2 max.

@Dan_Nash94 @reallyoptimized I do 17s/13s bc the Accel/decel of the treadmill. But I can do this 40x rpe 6…then I’ve tried holding that sprint pace at the end and I maybe last 3 min. Perhaps this is a good way to target clinical or deconditioned pops.

@AngelaDavies68 @JoseAntonioPhD Another good point. Put it first. I meet lots of people who put it at the end and lots of things prevent it. Damn, I dont even like to workout late most days. So it’s in AM and it’s Set the tone for most days.

@Go1MoreMile @JoseAntonioPhD Yes attainable if prioritise & enjoy eg daily: spin bike hour, rower 30 min, trail walk 3-6hrs & RT. Work part-time, kids grown up. Start day at 5am 7 days a week.

@jerryteixeira @JoseAntonioPhD I agree. In fact, the mindset is exercise is just something you get through. Never prioritized in any level, “if I have time ok, but I can’t make Time.” That attitude gets people some health/fitness but falls short of its real benefits. My life is built around exercise.

@CityRichmondVA @rvamayor just a reminder that the Leigh st bridge to VCU is a major thoroughfare for #bikecommuters to @VCU and @VCUHealth. Not everyone can drive to work. Please clear asap before tomorrows commute.

@AlisonSydor @CNN keeps citing the same OLD 2017 paper showing no advantage. It's weak journalism at best that ignores dozens of new research showing the opposite.

Honestly, where were the media w their critical questions the past 20+ y when women had obvious concerns about fairness I’d love to see an equal grilling of major sport CEOs allowing males into the female category. Would any of them even have the courage to do such an interview?

@CNN needs to stop citing that 2017 research article. That paper is out of date and there are now at least two dozen papers showing trans women's have a clear advantage. Just open your damn eyes! Trans women (ie, post puberty) have an unfair advantage. cnn.com/2024/03/03/us/…

@realSteveNagy1 @ACShilton Just to be clear though, our current study is home-based, so just about anyone in the lower 48 can enroll. You just need a smart trainer. We can supply the Zwift for the study period.

@tin_teacher @i_heart__bikes @sharrond62 We've already seen outright hate directed at women speaking out. Young women are the target of all sorts of attacks in person and on social media. Protect their sport regardless.

@i_heart__bikes @sharrond62 Second and third place facilitating their own demise

Is there anything Jenna (Jimmy) Lingwood can’t do?? He’s a dad. He’s a husband. He’s an engineer. AND he’s a consistent women’s elite cyclocross champion! Here he is winning the women’s 1/2 last night at StarCrossed in Seattle. (Psst ladies: Train harder!)

@ACShilton We're still recruiting!

@TimCycles @nealrogers HIs winning margin wasn't that much. If you look at that time trial, he was easily 2% better than normal, Pog's maybe 2% off, you get 4% diff. Journalists pretending to be exercise physiologists need better advisors.

@nealrogers Thoughts on the Vingegard performance? @Go1MoreMile

Wrote this three years ago, same sentiment applies today. Vingegaard's winning margin defies logic. That doesn't mean it wasn't legitimate — there's zero credible evidence to say otherwise — but cycling fans are well within their rights to have doubt, to pose questions. #TDF2023

This tweet aged well.

2/2...what we can surmise is #pogacar was a bit more than 2% high and #roglic 1% under. The point being, we incorrectly assume 57 sec is insurmountable but ignore the data. #lemond won bc of multiple factors AND a great ride. Thoughts @DrMJoyner @Scienceofsport @realBertBlocken?

Did #primozroglic collapse in the TT? Was this loss as dramatic as it seems? I’d argue no. 1) @LeTour top 10 is within 1% of the winner. 2) day-day variance in performance is 1-2%. 3) @rogla was 3.3% slower w/in top 5. 4) If @TamauPogi was on a great day and Roglic mediocre...1/2

@IkSendler @theagora42 @AaronSiriSG @joerogan Yes. You're cherry picking things to make a case. Literally EVERYTHING can cause cancer. All vaccines are monitored for safety where we have decades of data in some cases. I don't think you understand placebos. Placebos are inert for the active ingredient, not all ingredients.

@Go1MoreMile @theagora42 @AaronSiriSG @joerogan ✖️Most are not tested against a true inert placebo. ✖️In some, “they monitored safety” with preset checklists for only a few DAYS. ✖️Every vaccine insert on the childhood schedule states that it is not studied for carcinogenesis or mutagenesis. 🤔You call that “stringent”??

And @joerogan here is what happens when the world's most eminent vaccine scientists are asked questions about vaccines and autism when they must tell the truth under oath. thehighwire.com/ark-videos/pro… thehighwire.com/videos/do-vacc…

@sausagecz @lancearmstrong @YouTube Your anger is remarkable. You keep calling him my hero. But your statement lacks as much evidence as your logic lacks sense. Please seek help for your anger and bullying.

Carole Hooven on Transgender Athletes in Sports | The Forward with Lance... youtu.be/dTjdc1VBnqY via @YouTube In the sixth episode of this series, I am joined by @hoovlet, PhD, Evolutionary Biologist at Harvard University.

@KirstiMiller30 @lancearmstrong @YouTube @RogerPielkeJr You keep referring to non-athletes to make your case in athletes. That's really not matching. And again, what's with your fixation on height? I have to honest, you really don't understand what you're talking about. Athletes will best retain advantage esp past 2 years.

@Go1MoreMile @lancearmstrong @YouTube @RogerPielkeJr Both Roberts & Chiccarelli not matched for height show steady decrements in physical performance of non-athletic TW in the military, with no difference with CW for running times by 2ys meaning this group of TW lost 21% in running which is double the gender performance gap.

@KirstiMiller30 @lancearmstrong @YouTube @RogerPielkeJr What's your point here.

@Go1MoreMile @lancearmstrong @YouTube @RogerPielkeJr Bretherton Et al found overall body composition in trans women (fat mass 32.3%, lean mass 65.0%) was similar to cis women (fat mass 32.8%, lean mass 64.5%, p>0.05).
