@GDellaMattia I saw the PLT implementation and the paper. Very interesting concept! I hope you share the FMT implementation when ready :)

@jonhelge PLT w/ wko & recovery data simple Tensor , FMT .... testing. github.com/enydog/PLT

N=50 Simulation of 📉HRV behavior post-training across different phases of the prep cycle. With the same 🔢TSS, post-wko HRV improves as the athlete approaches peak 📈form. Identical TSS loads in different phases have distinct phys impacts — something the 🤖Tensor highlights.

@DrPhilipSkiba @Captain7bag Is the R chart for Golden Cheetah you reference available somewhere? Tried my best to to find it with no luck. The paper was a very interesting read!

Click through to read my science fair project with @Captain7bag ! Totally new way of analyzing the power duration/“MMP” curve.

@Alan_Couzens I went from 280W to 370W stryd power at threshold with 2.7 hours in average per week. Vo2max from 43 to approx 55. Doing mostly lactate guided threshold intervals @LT2. Was 41 when I started. By no means athletic background.

I guess my central thesis, if I had to sum it up... No one over the age of 40 will get fit on 150min/wk, irrespective of the intensity. Almost everyone over the age of 40 will get very fit on 150min/day, irrespective of the intensity.

@marceloheinig @SeanSeale @jem_arnold @MedBonnevie @StephenSeiler What model are you using? Is it published somewhere?

Hey everyone who loves to tinker with physiological models! I've built a personal project to estimate CP & W' from intervals under 3 minutes. (1st webapp - excuse any beginner's quirks!) Check it out: powerlab.icu @SeanSeale @jem_arnold @MedBonnevie @StephenSeiler

@pgalko How does it estimate the V02max?

The new Claude 3.7 is impressive! No matter how hard I tried, I was never able to get anything even close to the correct answer for VO2Max estimation using LLMs. Then Claude 3.7 casually produces this, as a zero-shot, no thinking response 😎

@SophieRHerzog @max_stoneking Not studies, but 13.1 matched my VO2 data well. blog.stryd.com/2019/12/06/how…

@jonhelge @max_stoneking I have a Stryd but would be careful with directly translating that. Do you know of any studies validating Stryd power / energy output?

How can an energy budget be used to inform a training process? Smart training starts with understanding the demands of your race & thinking of the specific capacity you need to build! The key is knowing what you need to WORK (😉) on! Read more👇 open.substack.com/pub/sherzog/p/…

@SophieRHerzog Interesting read! A limitation with budgeting with kJ is that the cost of increasing intensity is higher than the increase in kJ if time is constant. You would need some other guidelines as well to avoid burning yourself down.

@max_stoneking @SophieRHerzog Get a Stryd, and then it is only swimming left in the equation

@SophieRHerzog This was a fun read. Wish it were easier in triathlon to calculate workload like in cycling with a simple kJ readout!

@hasheddan @NordicTweets FYI: The precompiled production fw for the thingy:91 X can be found here github.com/hello-nrfcloud…

**USB UART on the Thingy:91 X** I wrote up a short post on accessing UARTs over USB on the new @NordicTweets Thingy:91 X via connectivity bridge on the nRF5340. danielmangum.com/posts/usb-uart…

@mikestrives SaaS

I make $55k/month with my SaaS. After studying all the successful strategies out there. I compiled the best ones into 1 BIG document. It's free for 48h if you: Like + Comment "SaaS" and I'll DM it to you. (must be following)

@amritwt @shadcn Can you share a link to your kit?

I just added @shadcn's sidebar to my free starter kit for indie hackers. It is really quick and easy to make a sidebar now.

I have been working on an application to help sport scientists streamline their Python data workflow. Here's a sneak peek at the onboarding process: From registration to Python in under 1 minute! Currently in closed beta. Learn more at sweatstack.no

Excited to announce #nRF9151 SiP, smallest and lowest power #cellularIoT solution & nRF9151 DK are in production! It supports #LTEM/#NBIoT & #DECT NR+, simplifying scalable product development in IoT markets. Get your nRF9151 DK 👉 hubs.li/Q02NMcFg0 @DECT_Forum

Looking for space movie recommendations? ai is not helping.

@pgalko @DataChaz You spend so much time with your LLM-agent that GPT4 thinks its your wife :D

@DataChaz Select my last 20 running activities. For each activity, list all distance intervals and plot the average heart rate for each interval on a bar plot. Use different colors to distinguish the activity intervals between different activities. 🤷‍♂️

Some weird shit coming out of GPT-4 today 🙈 Wait a minute... Maybe it is trying to tell me something 😂

@feelthebyrn1 @BasVanHooren @Alan_Couzens @justindaerr @jem_arnold @EliasLehtonen @CalibreBio Answering myself.. It is desribed here onlinelibrary.wiley.com/doi/10.1111/sm…

@feelthebyrn1 @BasVanHooren @Alan_Couzens @justindaerr @jem_arnold @EliasLehtonen @CalibreBio It might have been written before, but what kind of sensors are in these units? Is it proper O2 and CO2 measurements?

Calibre Bio As I figure out the device, I'll post here Tagging @BasVanHooren @Alan_Couzens @justindaerr // comments welcome! Vid clip is the dashboard To see the dashboard, I had to (re)login after creating an account & connecting 5 cal a minute and 1L VO2, sitting in a chair, seems way too high. However, I've been training all morning I'll let it sit for an hour and calibrate, again

@PughCycle Very cool project. Do you have any CO2 sensors in scope which looks to have right specs?

Next steps: Upgrade CO2 sensor for 0-10% range. Correct gas measures for hill climbing (altitude). Improve moisture removal - currently using cutout AeroPress filter. Modify Hans Rudolf mask instead of raspy 3M. Redesign enclosure as it’s hard to check over shoulder.

Metabolic carts are accurate yet pricey. Can a homemade analyser come close to their performance? This open-source Arduino device measures V̇O2, V̇CO2, and V̇E. I tested "VO24U" against a Parvo cart. @ShemRodger inspired this project while we supported the Tokyo 2020 TP.
