A week ago Kristian Blummenfelt posted a video of a high VO₂ Immediately, everyone was reporting it. I applaud scientists like @jemarnold.bsky.social to quickly share their skepticism whether this number is the worlds-highest VO2₂max and not not leave the field to uncritical media posts. BUT ⬇️

Successful science communication depends on a good match between platform and target audience. Who do you think is actually on Bluesky right now? And how would you tailor (science) communication to reach them effectively?

Where should scientists communicate science today? Recent discussions (IJSPP editorial; Ross Tucker on The Real Science of Sport) highlight the gap between the science we produce and the advice people receive. What platforms do you think work best for science communication? Let’s discuss 👇

Yesterday I got the opportunity to work with young triathletes on training intensity control. I believe with this topic, theoretical input is not enough. That's why we did a running session to practice the RPE scale and *experience* how the right intensity feels. Some reflections of the day 🧵

The final round of thesis proofreading has started. 🤓 On paper, to get an impression of the looks when printed. 🔜 Submission next week

Just published 🥳 Following the study in Ghanaian students, this study looks into factors affecting vaccination hesitancy in Ukrainian students 💉🦠 This was a great learning opportunity and I can see how my contribution to the paper (doing the statistics) has improved compared to the first study ⬇️

Cycling kit with an integrated full-body NIRS system at the Tour de France? 🚴‍♂️ We surely are far away from the vision presented in a review I was reading today. But I have to admit, such a technology would be highly intriguing, especially with the integrated display to oxygenation status 🤓

My first time at the #ECSS2025 I'm taking home many positive impressions - I've never seen this many sport scientists in one place! I enjoyed having Stephen Seiler as chair during my oral presentation. Finally I got to tell him what my thesis is all about 🤓

Our new durability paper is out in SJMSS! We tested how endurance performance determinants change after heavy-intensity running (90 and 120 min) in well-trained marathoners. 📌Below details of what we’ve found. 🆓 Open-Access 📄 onlinelibrary.wiley.com/doi/10.1111/... 🧵1/14

Broadly speaking, I agree with @thuyvytnguyen.bsky.social‬’s basic points. Good preregs take time and effort, analyses plans are very important, and clear hypotheses guide the analysis plan.

Only recently I complained about the use of tests for differences with NIRS data compared to other methods. I am pleased to see that testing for equivalence was used in this study, confirming that BPs and LTs are not the same ⬇️ www.frontiersin.org/journals/phy...

The latest from myself, @crist14n.bsky.social, Grant Abt, and @lakens.bsky.social on exploratory research in sport/exercise science. doi.org/10.1080/0264... We outline the differences between exploratory & confirmatory studies and best practice for conducting/reporting an exploratory study.

Just published 🥳 I am grateful to have been given the chance to be part of this project, which is potentially much more relevant than anything I am currently doing in sports science 👀 Under the guidance of Werner Pitsch, I was able to put my statistical skills to the test 🤓 A short 🧵⬇️ /1

In our recent meta-analysis with trained athletes, did the athletes who improved their VO2max more also improve their endurance performance more?🤔 No! 😮 In this dataset, +1% improvement in VO2max was associated with a negligible +0.04% change in TT performance. But why? 1/15🧵

Is there an equivalent of t test or anova when the looking of differences between functions rather than numeric values?

Random Sunday thought: The Joyner Model is typically used to predict performance for a specific distance/time. Has anyone tried to predict the power/speed duration curve using the model?

Another study found no mean differences between local and systemic breakpoints, but observed large individual differences. As this is reported again and again, maybe it is time to actually test for equivalence instead for differences? 🤔

What is the best way to report/visualize a multinomial logistic regression model? Any reading recommendations/examples? #stats #rstats

The joy of working with athletes and the importance of consistent work When working with developing athletes, it's all about doing decent work and not doing more than needed. Even a 6-week forced break following an injury shouldn't matter in the long run. Currently MMSS ~ 5W/kg with room to grow 📈

Three days ago, I deleted my X account. 🥳

🚨 New study 🚨 The biggest project of my PhD is out in MSSE journal. 🔑 findings: Strength training improves running economy durability & high-intensity performance following prolonged running. 🙏🏼 R. Blagrove and J. Folland for the SUPERvision on this. 🔗 journals.lww.com/acsm-msse/ab... 🧵 1/10

~ German Exercise Science and Training Conference ~ It was a pleasure to present the results of my master's thesis on my first conference 🎓 Great keynotes by Shona Halson, Andrew Jones and Dan Lorang! Three great days and lots of discussions with like-minded sport scientists 🤓

You will note how the drug schedules look suspiciously like the “periodization” (wink-wink-nudge-nudge) schedules found in many training manuals / books.

You there! Would you like to learn how to make very pretty graphs in #rstats? I'm delivering a short introduction to data viz in R on 15th April. Online, free (I think), and no prior knowledge or experience of R required. #AcademicSky www.apa.org/education-ca...

In our recent network meta-analysis we found: 🔴higher level competitive athletes improved VO2max modestly more with 🟣polarised training, and 🔷lower level recreational athletes increased more with 🔵pyramidal training This is what those differences looks like 👇 But is this meaningful? 🤔🧵1/12

I dislike articles having the methods as the last section.

I'm thrilled to announce that I'll be presenting at the German Exercise Science and Training Conference #GEST25 This marks my first conference attendance, and I'm proud to share the findings of my master's thesis on the effects of running training on vastus lateralis oxygenation

Exciting news! I’ll be presenting at the Moxy Summit 2025. Join me on 6th of Feb at 6:30pm CET, where I’ll be presenting on day-to-day variability and side differences of SmO₂. It’s free to register, and you can sign up here: us06web.zoom.us/webinar/regi... #MoxySummit #Research #SmO2 #MuscleOxygen

Is muscle oxygenation mNIRS symmetrical in both legs during cycling? 🤔 We often assume it is. But can we use one leg to represent the responses in both legs? Recently, two studies have come out examining bilateral reliability in one wearable NIRS: Moxy monitor What does the research suggest? 📚🧵👇

You always have to read carefully. I missed that the authors reported mean±SD instead of using LoA...

In a just published study, Sendra-Pérez er al. look at leg symmetry of muscle oxygenation during cycling exercise. A short summary of what they found: ➡️ SmO2 did not differ between legs in the VL, Gastroc and tib. ant. ➡️ SmO2 showed a similar response profile between sides 1/n ⬇️

I'm trying out this platform as Twitter is getting more unusable day by day.
