Chapter 11 Flashcards
A client has repeatedly exhibited a pre-exercise USG range between 1.028 and 1.032. How would a Nutrition Coach interpret this finding?
The client needs to increase their fluid intake between training bouts.
At what rate should individuals engaged in exercise in hot environments consume fluids?
There is no single fluid intake rate for all individuals
Which of the following responses occurs during exercise associated hyponatremia?
Extracellular fluid shifts inside cells.
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.”
Which of the following is an electrolyte?
Potassium
Which of the following electrolytes is found in the greatest concentration in the intracellular fluid?
Potassium
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 liters
A sweat-loss assessment has determined a client loses about 1.5 % of their body mass during a typical training session. The client trains 5 days per week. What is the best hydration advice for this client?
Drink ad libitum. If this does not assure the client, advise an extra 500 mL of water before bed and before reporting to train.
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.
Which of the following symptoms may be indicative of exertional rhabdomyolysis?
Extremely-dark-colored urine
Which range identifies the percentage of body mass that is comprised of water?
50-70%
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?
3.0 liters
Which item most accurately describes the role of fluid intake in regards to assisting body-temperature regulation during exercise in the heat?
Fluid intake can blunt increases in temperature during severe dehydration, but it cannot prevent all cases of heat illness.
What signaling mechanism triggers thirst due to a significant loss in total body water from sweating?
Baroreceptor
Urine-specific gravity is best assessed with which tool?
Refractometer
Which of the following compounds can passively cross a cell membrane?
Water
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
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%
For clients engaged in prolonged endurance events who know what their sweat losses will be, which is the most appropriate advice to give in regards to developing a competition hydration strategy?
Do not drink in excess of sweat losses and limit body mass loss to < 3-4%.
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.
What is the primary cause of exertional rhabdomyolysis?
An intense exercise session.
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.
