High-Intensity Interval Training: For Fitness, for Health or Both?

That which was old is new again. High-intensity interval training (HIIT) has been a common component of exercise regimens designed to improve fitness and performance for many generations. In recent years, research interest has surged. A simple search of PubMed for the term “high-intensity interval training” reveals a more than 20-fold increase in the number […]

Selecting the Right Fitness Facility for You

Prior to joining a health/fitness facility, you are encouraged to identify your major fitness and exercise goals. With fitness objectives established, start visiting fitness facilities that are easy access for you and your family (if you are seeking a family fitness membership). The fitness club should have a variety of exercise equipment and fitness programs […]

Air Quality and Outdoor Exercise

There is incontrovertible evidence linking poor air quality to adverse health outcomes. This is especially true for people with pre-existing conditions such as heart disease, stroke, asthma and chronic obstructive pulmonary disease. However, healthy people are at risk too. Exposure to air pollution has been linked to a higher risk of developing asthma, and recent […]

What’s New in the ACSM Pronouncement on Exercise and Hypertension?

Hypertension is a Pervasive Public Health Problem The American College of Cardiology (ACC)/ American Heart Association (AHA) Task Force on Clinical Practice Guidelines recently redefined hypertension to a lower blood pressure (BP) threshold of 130 mmHg for systolic BP (SBP) or 80 mmHg for diastolic BP (DBP) (1) versus the Joint National Commission 7 (JNC […]

Exercising in Hot and Cold Environments

Many people continue to participate in outdoor activities when seasonal changes occur. While it is very important to remain physically active throughout the year, it is equally important to prevent the risk for environmental-related injury. This downloadable guide contains advice for avoiding these injuries and conditions. Download the handout.

Five Frequently Asked Questions About the Physical Activity Guidelines

The US Department of Health and Human Services (DHHS) released the second edition of the Physical Activity Guidelines for Americans on November 12, 2018. The guidelines are meant to to help Americans understand the types and amounts of physical activity that offer important health benefits. #1 How many Americans meet the Physical Activity Guidelines? In 2017, only […]

Heart Health & Brain Health Go Hand-in-Hand

In February, we often see many people wearing the color Red. Wearing Red may be a tribute to St. Valentine, but the color Red should also serve as a reminder to take care of our hearts, as February is Heart Disease Month! According to the Center of Disease Control and Prevention, heart disease accounts for […]

How to Meet the Physical Activity Guidelines in Everyday Activities

The other day I heard a story about a woman who hated to exercise. She wanted nothing of it: going to the gym, sweating, walking on the treadmill. Boring. No way! She’d heard about the latest 2018 U.S. Physical Activity Guidelines, but had dismissed them as irrelevant to her life. Recently, she stumbled onto an article […]

Body Weight and Waist Circumference Trending Upward in Americans

Recently, the U.S. Department of Health and Human Services published a National Health Statistics Report updating the trends in body weight, height, waist circumference and body mass index (BMI) in the U.S. population. This update uses data from the National Health and Nutrition Examination Survey (NHANES) and primarily focuses on trends from 1999-2000 through 2015-2016. If you […]

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.
