Active Voice | Midlife Physical Activity and Heart Failure Prevention

Heart failure does not develop overnight. Rather, it is a disease that can progress over several decades; long before symptoms are apparent to the individual or their physician. During later, clinical stages of heart failure, it can be very difficult for the individual to be physically active at any level. While clinical heart failure is […]

Importance of Exercise in Hypertension Identification and Management

Hypertension, or high blood pressure, remains the leading modifiable cardiovascular disease risk factor. It is estimated that nearly half of American adults have hypertension, which is defined as a resting systolic blood pressure greater than or equal to 130 mmHg and/or a diastolic blood pressure greater than or equal to 80 mmHg. Even more alarming, […]

Diving into Health: Aquatic HIIT for Older Women

Recent public health guidelines emphasize the importance of high-intensity interval training (HIIT) as an effective strategy for improving cardiometabolic health, particularly among older adults. While land-based HIIT (L-HIIT) has gained popularity, it may not be the best fit for everyone, especially elderly individuals struggling with deconditioning and joint issues. This is where aquatic high-intensity interval […]

Cardiorespiratory Fitness and Platelet Reactivity

Low cardiorespiratory fitness (CRF) has long been linked to cardiovascular disease (CVD), and platelets are key mediators in atherosclerotic CVD and thrombosis. However, few prior studies have examined associations between fitness and platelets, the majority exploring platelet reactivity after acute exercise bouts and showing a transient platelet hyperreactivity phase. Studies that have looked at chronic […]

Ultramarathons and the Heart-Lung Interface

The popularity of ultramarathon trail running has increased rapidly in recent years, with thousands of events now held annually around the world. Ultramarathons are broadly defined by an event distance that exceeds the traditional marathon (42.195 km) and typically range from ~45 to 170 km. In contrast to the traditional marathon, ultramarathon events are frequently […]

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.
