In this review, we describe the pathophysiology of sarcopenia and cachexia, explore their definitions in the context of geriatric oncology, and examine assessment methods used in clinical practice. Great job Makis. @lsuchse @acsmnews @skppowers

@jem_arnold @MoxyMonitor @TrainRedSensors Currently yes. May try the ISS. We originally processed with MATLAB program by Terrance Ryan and Kevin McCully. Now we are working with Kevin and IRXstudio. Played around with creating R codes the https://t.co/ztU0joa9Ke assistance. We have the research grade trainred.

For years, my colleague, Prof. Martin Gibala, and I have appeared on literally hundreds of podcasts. Today, we dropped our own podcast! As lifetime faculty members of the McMaster Department of Kinesiology, we thought it was time for our take on reality in the world of exercise, nutrition, health, and more.

The Podcast is Real Exercise Science, and you can pick it up on all your favourite platforms.

The goal? Real science, not hype. Not fluff, not the latest paper, but evidence, with scientific humility. But reality means disappointment sometimes. That stuff you heard about protein, lifting, Zone 2, peptides, GLP-1... It's often more than the data shows, extrapolation, overstatement, or downright wrong.

Hard facts, no hype!

Episode 1 dropped today https://t.co/ekPprWMkYn and featured a chat about the updated American College of Sports Medicine position stand in honour of day 1 of the ACSM annual meeting in Salt Lake City!

I'm in Salt Lake City with Marty, and you can hear an amazing update on the position stand https://t.co/uG9pWYdQf9

Wednesday, May 27, 3:15-4:45 MDT - see you there.

Your hippocampus shrinks ~1 – 2% per year as you get older. This leads to worse cognitive performance, especially memory.

In this study, adults grew back 2% of their hippocampus in a year by walking 40 min just 3 times per week.

The control group hippocampus continued to shrink by 1.4%.

Walking isn't just about burning calories. It's one of the best things you can do for brain longevity.

Our lab is expanding and hiring both a postdoc and staff scientist! We study how metabolism and cell cycle states drive tumor progression, therapy response, and immune interactions. Philly is a great place to live and do research! See more at: https://t.co/Qptg5QHh66.
