Weight loss with GLP-1 medicines does not result in a disproportionate loss of muscle mass or function in obese mice and humans
Langer et al. show that GLP-1 medicines mildly reduce absolute muscle mass but improve relative mass and running performance in mice. Despite similar changes to body weight, GLP-1RA affects the muscle...

🧪 In our latest paper, my great student Christopher Hayden fed rats a small amount of adenine, which crystalizes and causes kidney disease. The paper's new finding was that tendon quality decreased significantly in both males and females. physoc.onlinelibrary.wiley.com/doi/10.1113/...

Our latest paper is a quite applied one. It is a readiness questionnaire for rock climbers. We think that this will provide a quantitative measure of the effect of different training methods on finger tendon health and performance. sportsmedicine-open.springeropen.com/articles/10.... 🧪

The VISA-C Questionnaire: A Self-Administered Assessment to Measure Finger/Hand/Wrist Pain in Climbers - Sports Medicine - Open
Background Rock climbing places high loads through the hands, wrists, and fingers, leading to high injury rates, with the highest proportion in the fingers. Until now, there has been no attempt to categorize pain in the forearm to assess readiness to train. The purpose of this study was to create a questionnaire, the VISA-C (Victorian Institute of Sports-like Assessment; C for climbing), to measure forearm pain and determine how pain limits training. Methods We asked rock climbers aged 18 to 50 years old, who met the participation criteria and gave consent, to complete a survey containing 8 questions. We analyzed data from climbers who responded to the online questionnaire in the 9-week period between November 5, 2024, and January 8, 2025. We obtained a diverse international sample with English-speaking respondents from 54 countries. We included a supplementary questionnaire to compare the survey results against participant demographics, lifestyle, health, and sport-specific history and habits. Results We analyzed data from 1,110 climbers who completed the form. VISA-C scores were significantly different as a function of pain. The mean VISA-C score of the group with no pain was the highest (83.21/100), lower in the group reporting some pain (72.28/100), and lowest in the most severe group with activity-limiting pain (60.05/100), indicating our questionnaire scales with pain severity. We then used the secondary data gathered on our participants to search for associations between pain or skill level and demographic, health, and training habits. Of these, only blood pressure was associated with differences in VISA-C scores. Conclusions VISA-C score scaled with pain and can be compared broadly across all major demographics. We observed interesting trends in our secondary analyses. Several variables correlated significantly with either VISA-C score or climbing skill level, but none correlated well with both. Many of the variables we compared agreed with existing literature or pointed to novel associations that warrant more investigation.

This should be a great session. Hopefully, we'll get to answer some questions on pros and cons of different models for studying this difficult tissue.

🧪 New paper alert! We keep trying to understand muscle-tendon crosstalk. Here we determined whether exosomes could explain why serum after resistance exercise makes bigger stronger tendons. Contrary to our hypothesis, it is not exosomes. The search goes on. www.sciencedirect.com/science/arti...

Following resistance exercise, systemic changes foster improved functionality of tendons and ligaments. Post-exercise, muscle tissue releases exosomes…

Diabetes affects millions of people, but what if we could better understand how the body naturally regulates blood sugar? Mark Huising is leading NIH-funded research to study how beta cells in the pancreas work together with neighboring cells that secrete hormones that control insulin secretion.
Headshot of Mark Huising against a dark blue background with white text that reads, "From labs to Lives: How Research Funding Solves Real World Problems" and his quote, "[Reduced federal funding] is already stymieing the vital trainee pipeline that U.S. biotech and pharmaceutical companies rely on to maintain the edge in their internationally competitive fields."
