I could use help PTs and muscle testing folks! Do you have any load cell recommendations to be used in a gym setting that allows real-time force feedback? The goal is to use it for knee extension training so it's even better if the feedback is easily viewable (monitor or app).

This #Opinion article from Matthew J. Fogarty (Department of Physiology and Biomedical Engineering, @MayoClinic) considers the concept of 'mild motor impairment '- a "harbinger of sarcopenia and frailty". 💬 buff.ly/2QfIh22

@skppowers I'm continually surprised by the prevalence of within-subject designs for comparing high and low load. Cross-education is real and it is optimized at higher intensities. There is likely a transfer effect+local training effect for the low load leg unlike the high load leg.

Strength training fans-check out this recent study published in JAP entitled "Divergent strength gains but similar hypertrophy after low-load and high-load resistance exercise training in trained individuals" journals.physiology.org/doi/full/10.11…

Neat story on two of my awesome undergrad researchers! The sky is the limit for these two.

Really happy to see the first study from my PhD now published in JCSM! Thanks to everyone involved who helped make this happen 🌟 Have a read if you are interested in sex hormones and muscle ageing 💪doi.org/10.1002/jcsm.1…

"Cut-off points for low relative Sit To Stand power 30-s STS test and Alcazar's equation adequately identified older people with frailty and were assoc w/ an increased risk of experiencing adverse conditions":

@MarcusDGon @GI_Pearls Longitudinal studies should show greater declines, but this is part of the reason sarcopenia has evolved to include muscle strength. If DEXA was predominantly used in these, true muscle mass is being missed

@GI_Pearls yes. big caveat is that these are not longitudinal. Maybe % changes will be more impressive.

We all know muscle mass decreases with age, right? So I went searching for the data. How big is the effect? NHANES suggests it's not that big: <1 kg/m2 pubmed.ncbi.nlm.nih.gov/19753111/

Muscle power 💥(ability to produce force fast) is more important than strength 💪in preventing falls in older adults👵: sciencedirect.com/science/articl…

Some great topics!

Muscle power 💪💥(the capacity to generate strength rapidly) is a critical determinant of physical performance🏋️‍♀️and more associated with negative outcome than muscle strength: sciencedirect.com/science/articl…

💯 Yet less individuals participate in resistance training. What's more concerning, I'm thinking many 40 and older are not aware of its necessity for health and are confused or lack confidence about this modality. The ones who need it most...
