Active Voice | Menstrual Cycle Phase-Based Training: Think Before You Sync

For decades, researchers excluded females from resistance training research, often because of concerns about how endogenous ovarian hormones might influence adaptations. Premenopausal female physiology is unique because ovarian hormone concentrations fluctuate throughout the menstrual cycle. In particular, estrogen concentrations typically peak during the late follicular phase before ovulation, while progesterone concentrations peak during the mid-luteal […]

Hot Topic | Energy Balance: A Key Component to Female Athlete Well-Being

Sports participation among women and girls has dramatically increased over the past decade, reflected in a record numbers of girls competing in high school and collegiate sports and women competing in the recent Olympic and Paralympic Games. For women and girls, sport participation is associated with opportunities to develop physical competence, improve components of fitness, […]

Navigating the CAAHEP Accreditation Requirements: What Program Directors Need to Know 

To address concerns surrounding the upcoming CAAHEP accreditation requirements for ACSM-EP and ACSM-CEP exams, the ACSM Certification Board recognizes two in-process stages along the accreditation pathway to ensure graduating students remain eligible without waiting for full programmatic accreditation.  If your institution is currently working through these updates, understanding these two milestones can help you address […]

Active Voice | Can Being More Active Prime Your Brain to Benefit More from Exercise?

A single bout of exercise can sharpen thinking. But does everyone’s brain respond in the same way? Probably not. The lifestyles of those who participate in exercise sessions will likely differ from person to person. Some spend much of their day sitting, while others accumulate considerably more light and moderate-to-vigorous physical activity. We wondered whether […]

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” […]

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.
