Hot Topic | What Myosin Fragmentation is Teaching Us about Exercise and Atrophy

If you coach, train, or treat athletes and patients, you’re aware that skeletal muscle adapts to the balance between building up (protein synthesis) and breaking down (protein breakdown). We’ve gotten remarkably good at measuring the “building up” side through stable isotope tracer methods, with newer methods enabling participants to orally consume them. The “breaking down” […]

Active Voice | With Resistance Training, Load is Only Half the Story

For decades, one question has dominated resistance-training research: How much weight should we lift? Many studies have compared heavy and light loads to identify the optimal stimulus for maximizing strength and muscle hypertrophy. These investigations have shaped coaching practice, informed resistance-training guidelines, and fueled one of the longest-running debates in exercise science. Yet this question […]

ACSM hosts “Fighting Physical Education Decline” webinar July 21, 2026  Physical education requirements are increasingly deprioritized in pre-k through college level curriculum, contributing to a decline in movement and physical activity among younger generations. Join us for this foundational EIM-On Campus (EIM-OC) webinar as we explore the shared purpose that unites us as ACSM members […]

Being Active with Your Young Child | Rx for Health

Encourage your child to be active to get them started on a lifetime of health. Play and movement activities help children develop important physical abilities, teaching confidence and motivation. Physical activity should be FUN and something they want to do on their own. Early activity is the stepping
stone to an active life.

Being Active for a Better Life | Rx for Health

Inactive people who start moving get the biggest bang for their buck. Experts now say that any physical activity counts – even
just a few minutes! Fit in 2, 5, 10 or 20 minutes throughout your day. Every active minute adds up to better health.

Being Active as We Get Older | Rx for Health

Our golden years can be powerful years. The older you are, the more you can benefit from physical activity. Experts now say that any physical activity counts toward better health – even just a few minutes!

Hot Topic | Maximizing Human Potential Through Exercise & Technology

I am truly honored to give the upcoming Joseph B. Wolffe Memorial Lecture at the 73rd ACSM Annual Meeting. However, contemplating what to talk about after almost half a century spent researching the interactions between exercise training, nutrition, and their impact on human health and performance required careful reflection! As a former competitive athlete and […]

GSSI Pre-Conference

The Physiology of Hydration: More Than Water Alone

This session explores the physiology of hydration through an integrated lens—examining how carbohydrate, sodium, flavor, and fluid interact to influence intake, absorption, retention, and performance. We’ll review current research on fluid balance, osmotic drivers, and palatability, highlighting mechanisms that underpin voluntary intake and thermoregulation. Attendees will gain insight into individualized strategies, including sweat profiling and timing approaches, to optimize euhydration and mitigate performance decrements associated with >2% body-mass loss. Practical applications will be linked to laboratory- and field-based research, ensuring translation from bench to field. This pre-conference equips you with evidence-based tools to support athlete hydration across diverse environments and sporting contexts.
