For PhD students, don't worry if the first draft of your first paper comes back to you like this. It is normal. This is a process. No one starts perfect.

- With @IAAFDoha2019 one week a away, I figured it might be interesting to look at why there might be hamstring pulls in the men's 200 and 400m sprints. Just a simple demonstration as to why increases in tendon stiffness (for the same muscle strength) cause muscle pulls/ruptures.
00:00 - A quick demonstration of stress shielding and stress relaxation and how they relate to tendon injury and repair. If you want to see how we use this to improve injured tendon check out this paper ncbi.nlm.nih.gov/m/pubmed/30299…
00:00 - For all of those who think that the protein in tendons and ligaments doesn't turn over. Sorry, the evidence suggests that protein turnover in loaded tendons and ligaments is HIGHER than muscle: journals.plos.org/plosone/articl….
- Like everyone else, I am sheltering in place. At this time, it is important to remember that activity is important. This recent JAMA paper shows that walking 10,000 steps decreases all cause mortality 4-fold compared to walking 2,000 steps per day. Stay active my firends.
- Running stress-relaxation tests on patellar tendons in the lab today. Beautiful curves. Note that 80% of the relaxation happens in the first thirty seconds. That is why we hold isometrics for thirty seconds to try to fix an injured tendon.
- Replying to @TStellingwerffComparative physiology is a great way to understand exercise physiology. I love looking at the flight muscles of birds (the way Holloszy did in his 1967 classic) to understand how basic muscle properties change with habitual exercise.
- One of my favorite graphics of muscle over age incorporates the fact that if you are in strongest 1/3 you live longer
- Really proud that @ucdavis is standing up to @ElsevierConnect on this issue. I am an Assoc. Editor of one of their journals, review tens of articles a year for them, and yet still have to pay huge fees to publish my articles. Meanwhile, they made > £900 million in 2018.
- Using all the toys today to try to understand how exercise increases collagen in ligaments.
00:00 - Athletes with the biggest energy deficiency have the highest body fat. Body weight is one thing. Body composition is another.
- Replying to @ChrisSchneiRUB and @TheMuscleTussleThat is why I always do comments for students in paper. Accept all is the enemy of actually learning
- Please RT & help me get the word out. I am actively looking for a postdoctoral fellow interested in working from humans to cell culture to understand how varying nutrition affects muscle growth and function. Come join a diverse group of scientists in a beautiful part of the world
