What Is a Normal Rating of Perceived Exertion During Maximal Exercise Testing?

There is an abundance of evidence demonstrating that high levels of cardiorespiratory fitness (CRF) are associated with decreased risk for early mortality, chronic disease and some infectious diseases, as well as lower health care costs. The evidence is so strong that the American Heart Association suggested CRF be considered a clinical vital sign that is regularly measured […]

New Insight into Vitamin D and Physical Performance

Vitamin D is widely known to play a role in musculoskeletal and immune health, and a deficiency is associated with a wide spectrum of disease states and impaired physical performance. Vitamin D is mainly synthesized by skin exposure to sunlight ultraviolet B radiation and only a small amount (~20%) of vitamin D is available from […]

What Do We Know about Epilepsy and Physical Activity?

Since November is National Epilepsy Awareness Month, I thought it would be appropriate to discuss some of the more recent guidance that’s come across ACSM’s editorial desk regarding epilepsy and physical activity, namely the findings laid out in this 2021 publication in Current Sports Medicine Reports.   The topic hits close to home, quite literally — in […]

Technogym HIIT Applications in Chronic Disease Q&A

If you’d like to view the full webinar with an opportunity to earn one CEC, click here Q: Do you have any thoughts on HIIT’s effect on cancer survivorship versus MICT, or can you reference any researchers working in this area? A: I believe there are large trials in prostate cancer and breast cancer ongoing with […]

Camínalo*: My LDTP Pathway

It was during the third year of my Ph.D. work at Boston University when I received a call from my undergraduate mentor at the University of Puerto Rico, and now colleague and friend, Julio Morales, Ph.D. Dr. Morales had a suggestion, he said “you should apply for the ACSM’s leadership program for minorities.” He explained […]

Young Runners Can Build a More Robust Skeleton with Multidirectional Sports

Distance running is popular due to its health benefits, low cost and accessibility. However, it is associated with high rates of overuse injuries. Particularly, female cross-country runners have some of the highest rates of bone-stress injuries, which include stress reactions and stress fractures. Poor bone health is a contributing factor in some athletes and can […]

Exploring the Physical Activity Decline in Childhood

There is no doubt that childhood and adolescence are decisive periods to acquire healthy lifestyle behaviors, like being physically active and participating in a variety of sports. When youngsters acquire an active lifestyle, there is a greater probability they will maintain it throughout their lives. The Active Healthy Kids Global Alliance released the Global Matrix 4.0 on […]

Muscle Strength Genotype Predicts Functional Capacity at Older Age

Throughout the lifespan, maximum hand grip strength reflects general health and vigor and is therefore commonly suggested to be a biomarker of aging. Although aging results in declines in muscle strength, individual strength changes follow a predictable pattern, as shown by strong correlations between measurements carried out decades apart. Family and twin studies have also […]

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.
