ACSM SIGs of the Month: Celebrating Collaboration, Innovation & Impact

ACSM’s Special Interest Groups (SIGs) bring together passionate educators, researchers, clinicians, practitioners, and students who are advancing a particular interest area of sports medicine and exercise science in meaningful ways. Since launching the SIG of the Month series last December, we have highlighted the Combat Sports, Exercise Science Education, Cancer, and Pregnancy and Postpartum SIGs, which truly demonstrates the breadth of […]

Why Knowledge Isn’t Enough: Behavioral Economics in Fitness Coaching

For fitness professionals, few things are more frustrating than watching a client ignore your guidance. Suddenly, you may start to question yourself – maybe I’m just not good enough. Or you flip the script and blame the client – they’re lazy, undisciplined, not committed. But here’s the catch: neither mindset helps you grow, and neither does much for the credibility of our […]

Hot Topic | Physiological Assessments Using Muscle Near-Infrared Spectroscopy (mNIRS)

What is muscle near-infrared spectroscopy (mNIRS)? Muscle near-infrared spectroscopy (mNIRS) is a non-invasive technique that can be used to measure the changes in blood volume and oxygenation responses within the smaller diameter blood vessels in skeletal muscle. This is possible because near infrared light (~700-900 nm) emitted into biological tissues can help determine the oxygenation […]

New evidence review of data from 30,000+ participants finds the biggest benefits come from consistency, not complicated programs The American College of Sports Medicine (ACSM) has published a new Position Stand summarizing resistance training recommendations for healthy adults — the first major update since 2009.  The Position Stand synthesized findings from 137 systematic reviews representing more than 30,000 participants, offering the most comprehensive evidence-based guidance to date […]

$100M in Grant Funding Available via Centers for Medicare & Medicaid Services

The Centers for Medicare & Medicaid Services (CMS) recently announced a transformative initiative with a mandatory focus on physical activity and nutrition: the “Make America Healthy Again: Enhancing Lifestyle and Evaluating Value-based Approaches Through Evidence(MAHA ELEVATE) Model.” The initiative will provide $100 million in funding for up to 30 grants to assess whole-person care approaches not currently covered by original Medicare.   For those interested in applying for the […]

Active Voice | Central + Peripheral Stimulation for Chronic Knee Osteoarthritis Pain

Roughly 645 million people suffer globally from knee osteoarthritis (KOA), ranking it among the most prominent disability causes. KOA prevalence increases with age, affecting approximately 10% of men and 13% of women over the age of 60. Pain is the primary symptom and prompts medical care, likely impairing functional mobility. First-line pain meds like nonsteroidal […]

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.
