So don't trust people just because they are bigger than somebody else. It's most likely due to genetics, not effort or knowledge about training

But here’s the real insight:
Hypertrophy was far more consistent within an individual than between individuals.
If you respond well in one limb, you tend to respond well everywhere.

For those suffering tendinopathy (our medically treating them). Our paper on why/how isometric loading improves tendon phenotype gives some molecular support to using 30s isometric holds in tendon repair. sciencedirect.com/science/ar…

Has this protocol with a 30 second isometric hold been shown to heal a partial tendon rupture? In this case, in the middle of the tendon.

Yes. It has. Here is one of the papers.

@MuscleScience hey keith, is there an accepted timeline for how long the effects of fluoroquinolone continue to to degrade tendons after stopping the antibiotics?

Interested in injury prevention and rehabilitation in baseball? This might be an interesting meeting.
I will talk about ways to possibly prevent injury and how to optimize native tissue repair after injury.
It should be fun!

The question of how incretin-mimetics (i.e., GLP-1RA like semaglutide) affect muscle mass and function is very important and has been haunting the field for quite a while now. So, I am particularly pleased to share our recent paper on the matter:

New career chapter 🔓 | Thankful for my mentors and support network after this 10 year post doc journey, which I wouldn’t change for the world 🌎. Excited for all the new challenges ahead 💪🏼.

Our pre-clinical studies are still going strong too. If you ever wonder how we exercise our 3D engineered human ligaments, here my student Jared Ong is loading them into their gym (bioreactor) and placing them in the incubator.

After six days of loading, we measure the size and strength of the ligaments by loading them into the 3D printed grips that we designed for our @instron material tester.

I'm super excited to start playing with our new @KangaTech_ KT360 RFD. We are hoping that this will help us develop the next generation of training plans to reverse tendinopathy. Studies on PHT, PT, AT, shoulder, and elbow programs are all in the works.

Here is a great opportunity to work with an outstanding young researcher. If you want to study muscle metabolism, you are going to want to apply for this position.
Hey Muscle And Metabolism Folks on Twitter, @LykkeSylow and I are looking for a Postdoc who is interested in applying for a prestigious @DDEA_Denmark fellowship with us. More details in the picture attached. Please share widely! @MYOTWlTTER

@MuscleScience do you have any articles of effects of caffeine on tendon health by chance?

Isometrics for the win! Dr. Keith Baar (@MuscleScience) was an awesome guest on the latest podcast; his research on isometric work has been incredibly impactful in the performance and rehab communities. ericcressey.com/csp-elite-ba…

Super fan of @MuscleScience since his research has helped me manage multiple injuries. High recommend
NEW podcast episode is up!
Dr. Keith Baar, UC Davis — Simple Exercises That Can Repair Tendons (Tennis Elbow, etc.), Collagen Fact vs. Fiction, Isometrics vs. Eccentrics, JAK Inhibitors, Growth Hormone vs. IGF-1, The Anti-RICE Protocol, and How to Use Load as an Anti-Inflammatory
Dr. Keith Baar is a Professor at the University of California, Davis in the Department of Physiology and Membrane Biology.
During his Ph.D. studies, his research revealed that mechanical strain on muscle fibers activates the mammalian target of rapamycin (mTOR) signaling pathway, a crucial regulator of muscular hypertrophy.
Subsequently, he studied the molecular dynamics of skeletal muscle adaptation to endurance training under the guidance of Dr. John Holloszy, a legend in the field of exercise physiology, considered the father of modern exercise biochemistry.
Building on all of this experience, he conducted research into tendon health and the potential for engineering ligaments, which could have implications for treatment and recovery from injuries.
Dr. Baar now runs the Functional Molecular Biology Lab at UC Davis. His lab’s work ranges from studying molecular changes in our cells to conducting studies to effect real-world improvements in people’s health, longevity, and quality of life.
Please enjoy!

Does anyone know if LC Labs is still open and shipping chemicals? I can't get a hold of anyone and just need to know if we need to look elsewhere. Thanks.
