Resistance and aerobic exercise with protein in older adults with obesity during energy restriction. The REPOWER study registered at #ISRCTN by @BelfieldArchie isrctn.com/ISRCTN13303580 #ClinicalTrials

New Paper⬇️We found that the human gut microbiome remains unchanged in the face of an intensive energy restriction and vigorous exercise intervention that markedly improved body composition and metabolic health in people with overweight/obesity. physoc.onlinelibrary.wiley.com/doi/10.1113/JP…

🚨Funded PhD opportunity @LboroSSEHS - starting October 2025! 🔓Exploring iron status and supplementation in athletic individuals. ✨Supervisory team: myself, @LJJ_nutrition and Lettie Bishop. 🔗 lboro.ac.uk/study/postgrad…

Our new review is out: Introducing the maximal anabolic intake 💪 ✅Protein requirements vs maximal anabolic intake ✅Nitrogen balance vs IAAO method ✅Why 95% CI =/= safety margin Let's break it down. 👇 1/🧵

Excited to see my second PhD study now online in @MSSEonline👇 journals.lww.com/acsm-msse/abst… @Jonnyquinlan @gareth_wallis @KorzepaMarie @BelfieldArchie @Sarkomere @ChurchwardVenne

Have you ever thought about how your muscles change when you lose weight and keep doing aerobic exercise? We did too, and investigated it. See the preprint for our latest work here: biorxiv.org/content/10.110…

1/10 Excited to write this thread summarizing our new paper in @NatMetabolism, which identifies a potentially critical part of the signaling pathway that drives skeletal muscle growth in response to resistance exercise! Free link rdcu.be/el9am #Myotwitter @NIH_NIAMS

Excited to share the culmination of all the food weighing, resistance exercise training and muscle prepping as part of my PhD is now available to read online and in a great home in The American Journal of Clinical Nutrition! ajcn.nutrition.org/article/S0002-…

New study in EJSS! 2 weeks of bed rest causes ~5% leg muscle loss in healthy adults. DXA, CT & MRI detect similar decline. MRI-based automated analysis offers a fast, reliable alternative to manual muscle quantification. 🔗 onlinelibrary.wiley.com/doi/10.1002/ej… #musclehealth #MRI #research

2024 Protein Nutrition Review! What's new in dietary protein? 🥩🫘 A brief overview of SEVEN insightful muscle protein synthesis (MPS) studies (references and links included) 👇🏽

That’s a wrap on PhD data collection🥳 After a long year of testing, 162 muscle samples, 162 blood samples, 297 saliva samples, 2160 knee extensions and a LOT of protein powder later, my 4th and final study is finished! Next up, analysis!

I am happy to see my second PhD study published with @gareth_wallis and AndyBlannin! “Effects of overnight-fasted versus fed-state exercise on the components of energy balance and interstitial glucose across four days in healthy adults” #carbohydrate pubmed.ncbi.nlm.nih.gov/39426734/

New paper providing age-referenced centiles enabling interpretation of the volume and intensity of accelerometer-assessed physical activity of UK adults relative to their peers. sciencedirect.com/science/articl…

Does REDs exist? Our new paper is out. It is a scientist's duty to keep challenging dogma's and ask questions! bit.ly/Does-REDs-exist

Excited to share our latest review in the Journal of Cachexia, Sarcopenia and Muscle @JCSM_cachexia. Here we show how mass spectrometry can be used to profile ubiquitin signalling in skeletal muscle. Great team effort with @HarveyEJohnston and @SamantLab onlinelibrary.wiley.com/doi/10.1002/jc…

Research participants needed! Researchers are recruiting older individuals for a study to understand the effects of protein and exercise during weight loss. If you are interested, please contact Archie Belfield at REPOWER@contacts.bham.ac.uk birmingham.ac.uk/repower

Their example will shine throughout history. 🕊️✨ #Day80

📢Work led by @BelfieldArchie looking at how sarcopenia prevalence differs by choice of function test in people with T2DM ➡️Functional performance impacted by obesity = resulting in change in prevalence @LDC_tweets @LeicResearch @proftomyates @profmjdavies @jack_sargeant ⁩

We suggest HGS and CST cannot be used interchangeably to assess for low muscle strength in individuals with T2D and with a high prevalence of overweight or obesity.

We found a higher prevalence of probable sarcopenia using CST vs HGS (31.7% vs 7.1%) and found CST, but not HGS, was associated with all measures of adiposity (BMI, WC etc) in both unadjusted and adjusted models.
