It was a pleasure to contribute a couple of chapters to this handbook with fantastic international collaborators @CameronMGee 🇨🇦 and @JanWvanDijk 🇳🇱 Thanks to @KatyGriggs and Joëlle Flück for the invitation😊 @UBSportExR @unibirmingham @ICORD_SCI 2/2

Great to receive a copy of this textbook in the post tinyurl.com/4vw25nkw @routledgebooks Thank you to the Editors for their hard work pulling together this comprehensive resource, which covers current and emerging topics in disability sport science 1/2

Is human energy expenditure constrained? I recently debated Herman Pontzer on this topic at RACMEM. My slides can be viewed here: linkedin.com/posts/javier-g…

My NYT editor: Wanna write something about sports/workout supplements? Me: Basically nothing works, IMO, other than a VERY short list the IOC drew up. Her: Okay, write that. So (after calling a few people) I did: nytimes.com/2025/09/15/wel…

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% change in VO2max was associated with only +0.04% change in TT performance. But why? 1/15🧵

INDUSTRY BIAS IN NUTRITION RESEARCH? One type of bias is publication bias (aka desk draw bias) Not publishing some studies due to the direction or strength of their findings eg. if findings do not conform to a hypothesis Is there evidence of this bias in nutrition research?

@TFallon_Physio Great point Thomas, fully agree. The site-specific effect of exercise will be an important factor in our future work!

@JanWvanDijk Interesting piece of work. Given the higher rates of upper limb injuries, particularly fractures within racing, it would be interesting to see if the inclusion of upper limb-ballistic type exercises has a similar effect on UL BMD as what is shown in your lower limb intervention

6/ Team effort: Led by @luukhil , with contributions from Nick van Schijndel, @VeraWeijer, @decroixlieselot, Judith Bons & Luc van Loon. Plus, key support from the cycling community! 👏

@jwhitfie Thanks Jamie, nice to hear!

This is a wonderful piece of work - I thoroughly enjoyed reading it and seeing how it addressed a relatively straightforward question in a unique population. More like this please!

14/end 🌟 Many thanks to the athletes who participated in this study and to the research team led by @veraweijer. This work was made possible with funding from @RegieorgaanSIA and @Eat2Move. @Jeukendrup @m3researchgroup @Robvanderwerf @HANsportnutr

13/ 📝 Yes, this is a small study with limitations. Still, we believe the findings add valuable insights into the potential uses and limitations of CGM in (Para) athletes. Want to explore more? Link to full paper is in first message, it is available #openaccess in @EurJSportSci.

Lessons Learned from Continuous Glucose Monitoring (CGM) in Para Cyclists 1/ CGM is increasingly explored as a tool to optimize dietary counseling in athletes. What can we learn from its application in Para athletes? Our new study investigated this: onlinelibrary.wiley.com/doi/10.1002/ej… 🧵
