Document Summary

Quiz in class time same format as the midterm (multiple,multiple) But based on the 3 papers that are listed on the instruction sheet. Use pubmed to locate papers, read them through a few times, meet with classmates log onto. Pubmed through the western library site (so we don t have to pay for them: good or bad study, what they did, what they found. Introduction: talk about why what they have done is important, past work how it leads up to what they did. Beta-alanine: used by body to make carnicine (buffer of acid formation in muscle, when you exercise hard and form a lot of lactic acid. accumulation of hydrogen ion (shuts down glycolysis) y why you can t exercise hard for a long period of time. If you can buffer than ion, you will prevent it from accumulating and allow you to exercise longer.

1. Which of the following statements are true regarding muscle glycogen.

There are multiple correct answers.

If exercise is not to be repeated within 12 hours, then glycogen restoration does not have to be immediately following exercise

The most rapid repletion of glycogen following exercise occurs in the first few hours post exercise.

Consuming some protein along with carbohydrate during immediate recovery from exercise is beneficial.

Higher glycemic index foods enhance glycogen restoration following exercise

It is best to always consume all recovery carbohydrate and protein within 15-30 minutes following exercise

Low carbohydrate diets decrease ones ability to recover from exercise.

2. Choose all statements that are correct and apply to rehydration following exercise

For each pound lost during exercise consume 2 cups of fluid

Choose fluids that help with glycogen restoration, rehydration and electrolyte replacement

For each pound lost during exercise consume 3 cups of fluid

Choose fluids that are low in sugar and sodium, goals listed in Dietary Guidelines.

3. Long term fasting causes which of the following (choose all that apply)?

Increased use of amino acids to make glucose

Inability to burn fat through aerobic metabolism

decreased muscle protein breakdown

Increased production of ketones as an alternative fuel supply

increase in glycerol used to make glucose

Increased use of glycogen for glucose

4. Which of the ergogenic aids discussed in the page 582-584 Nutrition Myth or Fact Section are: Safe, Effective (in some sports or training protocols) and are also legal/ permissible for use in non-professional sports (aka: sport performance) when used according to evidence -based dosing protocols.

3. If you exercise strenuously without sufficient oxygen, lacticacid accumulates and contributes to
muscle fatigue and soreness. When oxygen is later available, lacticacid must be oxidized to pyruvic
acid. The structure of lactic acid is shown below.
H3CCCOHHOOH(O)lactic oxidzining to acidpyruvic acid (showformula)
(a) Circle the alcohol functional group. Classify the alcohol asprimary, secondary, or tertiary.
(b) Predict the solubility and chromic acid test results for lacticacid.
(c) Complete the reaction equation above. Draw the formula of thereaction product, pyruvic acid.
