Question

46. Performance decrements during activity occur with decrease as little as ____ of our body water. 1-2% 2-3% 0.5-1% None of the above 47. ___ and ____ play a critical role in body water and electrolyte balance are: Insulin; glucagon Testosterone; estrogen ADH (antidiuretic hormone); aldosterone None of the above are correct 48. Electrolytes are considered Ions when placed in a solution and allow for adequate conduction of _____ charges. negative electrical neutral None of the above are correct 49. For moderate-intensity activity lasting LONGER than 2 hours and/or high intensity activity lasting LONGER than 1 hour, we recommend 30-45 g carbohydrate + 15g protein (along with electrolytes) dissolved in about 600ml water every _____ during activity. 1 hour 30 minutes 3 hours None of the above are correct?

Answer 1

46. Performance decrements during activity occur with decrease as little as ____ of our body water.

1-2%- It is incorrect because this does not affect performance much.

2-3% - It is correct a minimum of a 3% decrease will affect the performance.

0.5-1%- It is incorrect because this does not affect performance much.

None of the above- The correct answer is B.

So, the correct answer is B.

47. ___ and ____ play a critical role in body water and electrolyte balance are:

Insulin; glucagon- It is incorrect as they regulate blood sugar levels, not electrolyte balance.

Testosterone; estrogen - This is incorrect as they regulate the sexual characteristics.

ADH (antidiuretic hormone); aldosterone - It is correct as they regulate water balance and electrolyte balance. ADH helps in reabsorption of water and Aldosterone helps in reabsorption of sodium.

None of the above are correct - The correct answer is C.

48. Electrolytes are considered Ions when placed in a solution and allow for adequate conduction of _____ charges. negative- It is incorrect as all the charges are not negative.

electrical- It is correct as the charges are electrical.

neutral- It is incorrect as charges are not neutral.

None of the above are correct- It is incorrect as the correct answer is B.

So, the correct answer is B.
