🎓EDITOR'S CHOICE🎓 Hulmi (Jyväskylän yliopiston opettajankoulutuslaitos) et al. show that resistance training produces a substantial change in the proteome of skeletal muscle, most of which is reversible. Some proteins remain elevated, implying "muscle memory" of training. 🔗 buff.ly/DkHnDJZ

Great study by the The Hornberger Lab! They identify MAPK-pathway mediating muscle growth. Reminds us from our study with Simon Walker in 2012 were MAPK´s gamma isoform of p38 and ERK 1/2 were phosphorylated more after 5x10 reps than after 15x1 reps. tinyurl.com/279mma3w

Strength athletes 🏋️ and physique athletes 💪 differ in sport-specific muscle size and power. However, in both groups, muscle size contributes to muscle strength: pubmed.ncbi.nlm.nih.gov/40300761/

Can muscles “remember” past training? Resistance training triggers protein changes - most reverse with detraining, but some remain elevated 10 weeks later. This suggests a molecular “memory” that reflects prior training history. doi.org/10.1113/jp2881…

This study is super encouraging for anyone who’s taken a break from the gym—whether due to life getting in the way, an injury, or just needing a rest. The fact that your muscles can "remember" past training at the protein level, even after 10 weeks off, means you’re not starting

Why is the historically-esteemed journal British Journal of Sports Medicine (BJSM) 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/…

The title says it all. Periodizing training around the menstrual cycle is not supported by current research. Adjustments can be made to program variables based on symptoms that may occur throughout the cycle if/when warranted. journals.lww.com/nsca-scj/pages…

Presented at #ASCO25: A 3-year structured exercise program after adjuvant chemotherapy for colon cancer improved disease-free and overall survival, physical functioning, and fitness, as compared with health education alone. Full CHALLENGE phase 3 trial results:

Just when you think this nonsense can't get any worse, you find this hilarious attempt to lie about the lie: - we made a mistake and did not include the pre-registered primary endpoint when we full-well knew and then attempted to obscure the data and did not include it any of

So pleased to show that strength trained differ from non-trained in sub-cortical excitability. This work will lead to plenty future studies in this area of investigation. link.springer.com/epdf/10.1007/s… #jyunique Biology of Physical Activity

🎙️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/podcast/mos…

Dear Media, STOP calling RFK Jr a vaccine "skeptic". He is an antivaxx liar. An anti-science fearmonger. An exploitive brand builder. He has NOTHING to do with thoughtful skepticism. Don't normalize false balance, middle ground fallacies, or his harmful BS.

Dear Media,

Why low-intensity endurance training for athletes? In this perspective study, seven possible explanations for the purpose of excessive-volume low-intensity training in endurance athletes are proposed. link.springer.com/article/10.100…

Mechanical loading induces cell type-specific responses in endothelial (EC) and muscle cells. In ECs, mechanical loading increased serine synthesis and its enzyme PHGDH was highlighted as essential in regulating EC growth. tinyurl.com/45fub867 Riikka Kivelä Sakari Mäntyselkä

New study from us demonstrate beneficial effects of the combined gene delivery of myostatin propeptide and VEGF-B on muscle growth & body comp. The scRNAseq results suggest various cell types and their crosstalk contributing in muscle growth. tinyurl.com/4tnnrh7a Riikka Kivelä
