Chapter 11 Q's Flashcards
What role does pickle juice play in regards to client hydration status?
Pickle juice contains a high concentration of sodium which can increase thirst drive and aid in consumed fluid retention.
A client’s pre-exercise weight is 80.0 kg. Their post-exercise weight is 78.0 kg. They consumed 1.0 liters of fluid during training. What was the volume of their sweat loss?
3 L
A client weighs 70 kg and is training to complete a marathon in a time of about 4 h. The client’s sweat losses are expected to equal around 4 liters (about 6% of body mass). Which fluid intake goal would be most appropriate?
Drink 2 liters of fluid during the race.
Which range identifies the percentage of body mass that is comprised of water?
50-70%
Which of the following symptoms may be indicative of exertional rhabdomyolysis?
Extremely-dark-colored urine
Which of the following scenarios would create the most optimal conditions for decreasing body temperature increase during exercise if the temperature and humidity were equal under each training scenario?
Cycling for an hour outdoors at 20 miles/hour
Completing a step class
Running on a treadmill
Completing a spin class
Cycling for an hour outdoors at 20 miles/hour
A client’s pre-exercise weight is 75.0 kg. Their post-exercise weight is 73.5 kg. They consumed 0.25 liters of fluid during training. What was the volume of their sweat loss?
1.75 L
A client weighs 50 kg and is training to complete a cool weather half-marathon in a time of about 2 h. The client’s sweat losses are expected to equal 2 liters (about 4% of body mass). Which fluid intake goal would be most appropriate?
Begin the race euhydrated and simply drink to thirst.
Drink 2 liters of water during the race.
Drink 2 liters of sports beverage during the race.
Drink 1 liter of water and 1 liter of sports beverage during the race.
Begin the race euhydrated and simply drink to thirst.
When assessing a client’s sweat losses, a Nutrition Coach determines that their change in body mass is approximately 1.5 kg. How many liters of sweat does this equal?
1.5 L
Which individual would be most likely to be at risk for exercise associated hyponatremia?
A runner completing a 4.5 hour marathon in cool weather.
A runner completing a marathon in 2.75 hours in hot weather.
An individual completing a 1 hour spin class in a cool room.
An individual completing a spin class in warm spin room.
A runner completing a 4.5 hour marathon in cool weather.
Which of the following compounds can passively cross a cell membrane?
water
Where is approximately 2/3 of body water found?
intracellular fluid
What is the minimum percentage of beverage fluid replacement range that should be suggested for clients who lose more than 3% of their body mass during training and train more than once over a 24-hour period?
110-120%
A client has repeatedly exhibited a pre-exercise USG range between 1.014 and 1.018. How would a Nutrition Coach interpret this finding?
The client is doing a great job of meeting recovery fluid intake needs.
A client completes three weight-training sessions with a Personal Trainer per week but also completes three, 1-hour group indoor cycle per week (not on the same day). They ask their Nutrition Coach for hydration advice. Which of the following responses would be most appropriate?
“Your workout sessions are not long enough in duration to cause sweat losses that dictate a personal hydration plan. Keep fluids available during exercise, and drink based on thirst.”
“Drink sports drinks instead of water on days you go to indoor cycle class.”
“Determine your sweat losses and seek to replace 100% of your sweat losses with fluid intake during the indoor cycle class.”
“Drink 250 mL of fluids every 30 minutes during training.”
“Your workout sessions are not long enough in duration to cause sweat losses that dictate a personal hydration plan. Keep fluids available during exercise, and drink based on thirst.”
Which of the following electrolytes is found in the greatest concentration in the extracellular fluid?
sodium
Which item most appropriately describes the use of urine-specific gravity?
It should be assessed multiple times before exercise to determine if clients with heavy sweat losses routinely fail to consume adequate fluid during recovery.
Only use USG after exercise.
It should be used during very-long-duration exercise to determine real-time hydration status.
It is a great tool to determine if sodium intake is too high.
It should be assessed multiple times before exercise to determine if clients with heavy sweat losses routinely fail to consume adequate fluid during recovery.
Which of the following electrolytes is found in the greatest concentration in the intracellular fluid?
Potassium
Which of the following responses occurs during exercise associated hyponatremia?
Extracellular fluid shifts inside cells.
Intracellular fluid shifts outside of the cell.
There is a large increase of sodium concentration in the extracellular fluid.
There is a large increase in sodium concentration in the intracellular fluid.
Extracellular fluid shifts inside cells.
What is the body’s primary pathway of heat dissipation during exercise in the heat?
Evaporation of sweat loss from the skin
A client who trains for triathlons has asked how much fluid he should consume between his morning runs and afternoon bike rides. He has determined his sweat losses from his early morning runs average around 2 liters. Which range of fluid intake would be most appropriate?
2.5-3.0 liters
1.0-1.5 liters
1.5-2.0 liters
3.0-3.5 liters
2.5-3.0 liters
