I've been slowly compiling this list of sport science/ex phys accounts since the early 2010s. It's heavy on the endurance sport and environmental physiology side, but hopefully some people will find it useful. Recommendations for additions welcome! twitter.com/i/lists/128965…

@Scienceofsport I’m not surprised at all. @BJSM_BMJ as been an ideological rag for years now. Seems to be the case for a number of medical journals, @TheLancet included. It’s sad really. They’ve become the thing they are supposed to rebuke.

It was a disappointing Review, because it used weak, inappropriate studies to answer questions it over-reached to answer. More disappointing is its promotion by a journal now advocating ideology that undermines fairness for women in sport. My thoughts: x.com/Scienceofsport…

Found this today in an old article I wrote. What I sent @cyclingtips (now @outsidemagazine) to publish vs. what actually got published😅. #cycling #physiology #EpsteinFiles

Watch me commit career suicide in high-performance cycling with one tweet: The number one dumbest thing in high-performance cycling is the fact proven ex-dopers are allowed to work in the sport after their pro career ended. These people should not be offered a job in a bike shop let alone work with impressionable young athletes on high-performance teams. You will never be able to convince the general public the sport is anti-doping as long as these people are allowed to freely work in it. It's also not fair to clean athletes who end up on teams with ex-doper staff. Why should their reputation and performance risk being questioned because they ended up on a team with some loser cheat? SEND A FUCKING MESSAGE ALREADY!!! Call out the individuals. Call out the management. Call out the teams. Call out the sponsors. (Below if you like). Fuck these people.

@Rainmaker1973 You don't have to be a perfect dad to make a massive positive impact in a child's life. Be there dads. Do your best. Society needs your contribution to your family in order to flourish.

Name one.

Not to jinx it, but @GoogleAI has already credited @EvenepoelRemco with the @UCI_cycling World Time Trial Championship win in Kigali, Rwanda this weekend. Congrats, mate?😄

@jem_arnold If you go the Infocrank route let me know. I can introduce you to their rep. Just to be certain, you have this Velotron user guide in your possession? It includes information on the SpinScan. If not, I can flick the pdf to you. Just DM me.

@boyntoncoaching Thanks Jason. Haven't thought about infocrank yet, that could be an option. Trying what we have first. Ya, we have the documentation. Last time we tried SRAM they didn't have anyone left who could support Velotron, so I'm turning to the wild mages here😅

can anyone recall the ancient magicks of recording high frequency pedal forces with Velotron? 🧙‍♂️ Is this possible? It clearly knows about forces through each pedal stroke, but can we export it somewhere? Looking for high sample rate options for a study

@jem_arnold Also, Racermate was bought by the SRAM/Quarq group. Maybe call their tech support and see if they can hunt you down their old manuals.

@jem_arnold I’m struggling to remember because it’s been years, but in lieu of that maybe install a new old stock OG Infocrank on your Velotron. Relatively inexpensive, super accurate, and high sampling rate. Are able to find/retrieve the data files from the simulation and erg mode?

@spragg247 I always send them back my hourly consulting rate. I don’t know if that put me on some kind of list, but I haven’t been asked to peer review in ages.

Academia is bathsit Journal editor: Can you review this paper Me: no, sorry. No capacity at the moment & I'm not really in academia, so reviewing less & less. Try x,y,z Journal editor: You failed to properly respond to my email as you didn't click the link & select a response

I want to bust a common #Cycling myth 💥 That spinning at high cadences is "more aerobic," shifting power from the muscles to the cardiovascular system, thus ⬇️ fatigue & ⬆️ performance. But science tells a different story. Let's break down the evidence. #CyclingScience 🚴🧵👇

@Cyrus_Monk @MenaspaP @AbbissC It is plausible. But you can also hand draw similar data on a graph and say it’s plausible for the conditions. The question is, is it accurate? And that’s where the doubt creeps in, given the validation data of the CORE device and it’s method for estimating core temperature.

Any exercise physiologists out there thinking these numbers are in any way plausible? Definitely cooked it up and noticed a performance decrease but also didn’t end up in hospital as this data would suggest. @boyntoncoaching @MenaspaP @AbbissC

Been lucky enough to get access to a few CORE sensors over the last few years to aid heat prep for races. Can’t say I rely on them solely for executing heat acclimation sessions and this is partly why. Graph from Stage 1 Tour of Thailand today in 38°C.

I don't see 'marginal gains' and 'mastering the basics' as mutually exclusive practices. 'Mastering the basics' can come down to understanding the intricate details and nuance of key components of elite performance. Paradoxically, (and depending who is defining it) 'marginal gains' is a detailed orientated pursuit. Done right, I believe both pursuits can occur without enforcing absurd rigidity.

A cool trick. My birthday is March 7th. If you type 0307 straight after a capital V and hold down the Alt key and press x, the rate dot will automatically appear above the V. So, if you want to put the dot over the V for VO2, remember my birthday and hey presto! You’re welcome ☺️

@jwhitfie *Perth, Australia has entered the chat*

For my money Melbourne has to be one of the greatest sporting cities in the world. My bike commute routinely takes me past walkers, runners, rowers & other cyclists and through the grounds of the MCG, Australian Open tennis, & the sounds of Formula 1 this morning. Can’t beat it!

A few months back I was interviewed by @GQMagazine for an article on the benefits of moderate intensity exercise. gq.com/story/moderate… It is important to exercise regularly to maintain and improve both health and performance. However, importantly, when exercise frequency is high it is important to vary exercise intensity across your workouts. In other words, not all workouts need to be performed 'all-out' to reap the benefits of exercise. Indeed, exercising too often at too high an intensity can have negative effects on health, performance, and overall well-being.

I like to say, (like models) all training zones are wrong, but some are useful. Re: physiological anchor. I think if you ask the big sport scientist proponents of Zone 2 they'll tell you it is anchored to LT1. But whether Zone 2 "straddles" LT1 or sits below it is unclear to me. 2of2

@SirenSeiler Yes. That's the difference between training zones and exercise domains. The definition of a training zone depends on who is defining it. They are constructs/tools used to convey a complex topic (exercise intensity) in a simplified manner for a practical purpose/outcome. 1of2

In your opinion, what is the DEFINITION OF ZONE 2 based on %HRmax? In the 5-zone model, it corresponds to about 72-82% of HRmax. In other words, «steady state» or just below LT1 (depending on training level).
