Acuity Research Digest

The Research

The American College of Sports Medicine (ACSM) recommends beginning exercise in a well-hydrated state with normal electrolyte levels. According to its Position Stand on Exercise and Fluid Replacement, athletes should begin drinking fluids several hours before activity when appropriate. This allows the body time to absorb fluids and return to normal hydration before training or competition.

The ACSM also emphasizes that hydration needs vary depending on:

• Exercise intensity
• Exercise duration
• Temperature
• Humidity
• Individual sweat rate

What This Means for Athletes

Rather than using a one-size-fits-all approach, hydration plans should be individualized.

Waiting until you feel thirsty during practice is often too late.

Developing a hydration routine before workouts helps athletes begin training better prepared, especially during hot weather or high-intensity sessions.

Where Acuity Fits

Acuity is designed to be part of an athlete's hydration routine before, during, and after training.

Its purpose is to support athletes who are working to stay hydrated throughout demanding workouts and competition.

The Research

The National Athletic Trainers' Association (NATA) recommends individualized hydration plans rather than a single recommendation for every athlete. Factors such as body size, sweat rate, exercise intensity, clothing, environment, and sport all influence fluid needs.

The position statement encourages coaches and athletes to:

• Learn their personal sweat patterns.
• Replace fluids before, during, and after activity.
• Avoid both underhydration and excessive fluid intake.
• Develop hydration habits that match their training environment.

Why This Matters

Two athletes running the same workout on the same day may lose very different amounts of fluid through sweat.

Individual planning helps athletes develop consistent hydration habits throughout the season.

Where Acuity Fits

Acuity is intended to complement an athlete's overall hydration plan.

Whether preparing for practice, competing in tournaments, or training in hot conditions, athletes benefit from consistent hydration habits tailored to their own needs.

The Research

Hydration is important for more than physical performance.

Multiple studies have examined how hydration status relates to attention, reaction time, short-term memory, and mood. Research suggests dehydration may negatively affect certain aspects of cognitive performance, while rehydration has been associated with improvements in attention and reductions in fatigue in some settings.

Researchers continue to study these relationships, and results vary depending on the population, level of dehydration, and testing methods.

Why This Matters

Athletes rely on more than strength and speed.

They also depend on:

• Decision-making
• Focus
• Concentration
• Reaction time
• Maintaining attention throughout practice and competition

Where Acuity Fits

Acuity is designed for athletes who want a hydration product as part of their training and competition routine.

Proper hydration is one factor that supports athletes during both physical and mental demands.
