Water & electrolytes P3

What are the four key steps involved in creating an individualized hydration plan?

1. Assessment (evaluate current hydration status)

2. Goals (define desired hydration outcomes)

3. Actions (implement strategies to achieve goals)

4. Reassessment (monitor progress and adjust the plan as needed).

According to body weight changes, what percentage decrease indicates an athlete is well-hydrated?

$<1\%$ decrease in body weight.

What percentage decrease in body weight indicates minimal dehydration?

$1\text{--}2\%$ decrease.

What percentage decrease in body weight indicates significant dehydration?

$3\text{--}5\%$ decrease.

What urine color generally indicates good hydration?

Pale yellow.

Why is thirst not always a reliable indicator of hydration needs?

Thirst may not always be reliable, especially during prolonged exercise.

If an athlete is evaluated as generally euhydrated during assessment, what does that indicate about their fluid intake?

Their $24$-hour fluid intake appears to be appropriate.

What action should be taken if an athlete is assessed as not generally euhydrated?

Total daily fluid intake should be evaluated and adjusted.

What should an athlete consume prior to exercise if their only goal is euhydration?

Water intake is sufficient.

What options should an athlete choose from prior to exercise if carbohydrates are needed?

A sports beverage, carb gel and water, or carb-containing food and water.

During exercise, what intake is sufficient if an athlete only needs fluid?

Water may be sufficient.

What options should an athlete choose from during exercise if sodium is also needed?

A sodium-containing sports beverage, sodium-containing food and water, or a salt supplement.

What are the athlete's goals after exercise regarding replenishment?

Replenish water, carbohydrate, and sodium as needed with a combination of foods and beverages.

In the sweat rate calculation, what is the conversion factor used to convert pounds ($\text{lbs}$) lost to ounces?

$1\,\text{lb} = 16\,\text{ounces}$.

How is total fluid loss (in ounces) calculated during a sweat rate assessment?

Add ounces of fluid consumed to ounces of weight lost, then subtract ounces of urine excreted.

How is the sweat rate per minute calculated?

Divide total fluid loss (in ounces) by the duration of exercise in minutes.

How is sweat rate per hour obtained from the sweat rate per minute?

Multiply the sweat rate per minute by $60$.

When drinking by schedule, what percentage of usual sweat rate should be consumed during activity?

Consume $60\%$ of usual sweat rate during activity.

Up to how much daily caffeine can be included in beverages that contribute to fluid intake?

Up to $450\,\text{mg}$ per day.

What effect does alcohol have on the body, even though it can contribute to fluid intake?

It has a diuretic effect.

According to NATA recommendations, what two modifications to beverages can increase consumption?

Flavoring beverages to personal preferences and serving them cool.

What two conditions does NATA recommend recognizing the signs and symptoms of?

Dehydration and hyponatremia.

Why do hot and humid environments increase the risk of dehydration and heat injury?

Due to reduced heat dissipation.

In cold environments, what factors affect fluid loss and intake?

Greater respiratory fluid losses, sweat loss when wearing layered clothing, and decreased fluid intake due to reduced thirst perception.

What three factors are evaluated in the Assessment of Hydration Status Tool (Figure 7.21) represented by WUT?

W (Weight loss: daily body weight changes)

U (Urine color: the color of urine)

T (Thirst: subjective feeling of thirst).
