How much fluid does AFAA recommend participants consume before exercise?

The recommendation of 8 to 12 ounces of fluid before exercise is grounded in the need for adequate hydration to support optimal physical performance. Consuming this amount allows the body to maintain its fluid balance, which is crucial for various physiological functions, including temperature regulation, muscle function, and joint lubrication.

Prior to engaging in physical activity, individuals should ensure they are well-hydrated, as dehydration can lead to decreased performance and an increased risk of injury. The amount specified helps ensure that the body has enough fluid to compensate for the typical fluid losses experienced during exercise and prepares the cardiovascular system for the demands of physical activity.

In contrast, lesser amounts may not sufficiently account for the fluid needs of an individual, especially if they begin exercising at a level that induces sweating and increases heart rate. The higher options do not reflect the typical pre-exercise hydration recommendation, as consuming very large volumes of fluid may lead to discomfort or unnecessary bloating during the workout.
