Document Summary

Check webct assignment based on last name. Effects on intense repeated performance slide 34. Similar work on rower or treadmill --- this study was on a bike. Whether it be peak or average: creatine subjects go harder and can average a higher power output for whatever 10 second power output you re looking at. Can be shown in trained and untrained people. Creatine has a significant effect on power: creatine allows you to recover quicker between repeated intervals. Ingestion of caffeine does not interfere with cr effects slide 35. Study 1996-7: does the combo of caffeine and creatine do better than either one individually: both have been known to produce ergogenic effects. caffeine has effects on cns: showed: combined group did worse than individual groups. suggesting interference between caffeine and creatine: for a few years, people said: shouldn t be drinking coffee when you re taking creatine because they interfere.

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.

Psychology question

In a research project intended to gather data on the effects of type of study method on examination performance,subjects are randomly assigned to one of two conditions. In one condition,they study alone,using notes they took during class lectures.In a second condition ,subjects study interactive groups with notes from class lectures.The amount of time spent studying is held constant .All students then take the same exam In this study:

a.What is the independent variable?

b.What is the dependent variable?

c.Identify the control and experimental groups.

d.Is the independent variable manipulated,or is it a participant variable?

Question 13

A swimmer you are training for a 100-meter swim even reports that he is taking a supplement that improves isocitrate dehydrogenase activity. Assuming that the typical swim time for this individual is 52 seconds the likely effect would be:

	A.	Greatly improved swim performance
	B.	Worsened swim performance
	C.	No change
	D.	Not enough information

Question 14

Which of the following reactions will result in the most ATP production?

	A.	Breakdown of 30 mols of creatine phosphate (CP)
	B.	Complete oxidation of 5.0 mols pyruvic acid or pyruvate
	C.	Oxidation of 10 mols of NADH + H⁺
	D.	Breakdown of 2 mols of glucose to 4 mols of lactic acid

Question 15

Why does muscular work become increasingly difficult with lactic acid accumulation?

		because lactic acid causes muscle injury
		because lactic acid interferes with the diffusion of oxygen into mitochondria.
		because lactic acid causes a rise in muscle temperature with renders enzymes involved in the glycolysis and the citric cycle non-functional
		because the rising concentration of hydrogen ions leads to a drop in ph which renders enzymes involved in the glycolysis and the citric cycle non-functional

Question 16

A 100-meter sprinter that you are training reports that a friend suggested that he take a supplement called âSprintex.â The label states that consuming this supplement will âturbocharge your mitochondria.â What effect would this supplement have on the athleteâs sprint performance?

	A.	Improve
	B.	Worsen
	C.	No Change
	D.	Can't tell

Question 17

The RQ measured for a subject who has been jogging easily at 70% VO2max for about 40 minutes and is in a steady state will likely be?

over 1.0

close to .7

close to .5
