On 4 July I’m doing the @alzheimerssoc Trek26 marathon in the Lake District. My dad died of Alzheimer’s in 2024. Funds are needed for research, to support those living with Alzheimer’s, as well as those caring for them. Donations greatly appreciated. justgiving.com/fundraising/G…

"At the Journal of Sports Sciences, we have a long history of publishing articles and editorials on research design and statistical matters. To help you find many of these articles we've created an article collection. Enjoy!" - @grantabt 👉tandfonline.com/journals/rjs…

For more info on exploratory/confirmatory studies, preregistration, and Registered Reports, see these two recent papers. tandfonline.com/doi/full/10.… tandfonline.com/doi/full/10.…

We're proud to support Open Science Badges, an initiative that promotes transparency and reproducibility. So far, seven articles earned a badge for open practices. But none have yet received the Preregistered badge. We strongly encourage preregistration for confirmatory studies.

That’s right, because academics are just income streams according to the bean counters. 🤦🏼‍♂️ Academia’s obsession with grant income.

Today I pushed the ‘Accept in Principle’ button on another @JSportsSci Registered Report. If you’re interested in finding out more about Registered Reports then read our editorial. tandfonline.com/doi/full/10.…

🎙️New podcast: The Replication Crisis Hits Sports Science. 72% of sports science studies could NOT be replicated. Effect sizes dropped 75%. Nearly 90% of researchers wouldn’t even share data. We explore bad incentives, a crisis of trust & how to fix it 🎧 podcasts.apple.com/za/podcas…

A monumental effort by a huge team to complete the first large replication project in sports and exercise science. Part 1 includes the results of the replication project: doi.org/10.1007/s40279-025-0… Part 2 includes reflections: doi.org/10.1007/s40279-025-0… @ExPhysStudent @JoeWarne1

🚨Recommended reading! Particularly part 3, which is all too common in sport and exercise science. P > .05 and underpowered mzloteanu.substack.com/p/wha… P > .05 but sufficient data mzloteanu.substack.com/p/wha… Underpowered but P < .05 mzloteanu.substack.com/p/wha…

We also published a more comprehensive pre-print @SportRxiv to elaborate on some of our points… sportrxiv.org/index.php/serv… @ChrisKirk_ASP @grantabt @TLexercise @cathydevine56 @evacarneiro

Why is the historically-esteemed journal @BJSM_BMJ publishing unequivocally poor research, just because transwomen are included in the studies? It makes no sense. We wrote a response to highlight some of the major flaws in the Alvares et al. (2025) paper.. bjsm.bmj.com/content/early/2…

What makes exploratory research valuable? We discuss 6 factors: 1) Large and 2) Uncommon sample 3) Rigorous data collection 4) Widely used measures that 5) Reveal a coherent pattern across variables and 6) The potential to generate questions. doi.org/10.1080/02640414.202…

Sometimes you need a carrot, sometimes you need a (small) stick. @JSportsSci we've introduced a mandatory sample size estimation and justification section to manuscripts. The rationale is outlined in the editorial. Editorial tandfonline.com/doi/full/10.… IFA tandfonline.com/action/autho…

As a companion piece to our recent paper (tandfonline.com/doi/full/10.…), at @E_C_S_S Rimini this year we present a poster on exploratory research. IS EXPLORATORY RESEARCH MISUNDERSTOOD IN SPORT AND EXERCISE SCIENCE? 04.07.2025, 11:00 - 12:00, Hall 5 (Poster Session 3) @lakens

The latest from Max Ditroilo, Cris Mesquida, me, & @lakens on exploratory studies in sport/exercise science. Inter alia, we outline the differences between exploratory & confirmatory studies and best practice for conducting/reporting an exploratory study. tandfonline.com/doi/full/10.…

*NEW* @JSportsSci now offers the ‘Preregistration+’ open science badge! Criteria outlined below. More info in the second link. osf.io/tvyxz/wiki/1.%20View%… authorservices.taylorandfran…

On 10 May I'll be doing the Trek26 marathon challenge around Stonehenge in aid of @alzheimerssoc and in memory of my dad who passed away last year from this horrible disease. If you can spare a little change then all donations are greatly appreciated. justgiving.com/fundraising/T…

The wording in Trump’s executive order is fine (well, I dislike “conception” but that’s a minor quibble). Sex is determined at fertilisation. We can predict the sex class of an embryo well before any sex phenotype develops, and with almost-perfect reliability. Human embryos do not all start as female. This is a scientifically-illiterate claim.
