Carbohydrate

Drag the descriptor to its appropriate lipoprotein classification

Chylomicron- Carries absorbed fat to body cells VLDL- Carries fat taken up from the bloodstream by the liver as well as any fat made by the liver, to body cells HDL- Arises mostly from the liver and intestine and carries cholesterol from cells to other lipoproteins to the liver for excretion LDL- Arises from VLDL and carries mostly cholesterol to cells.

Which of the following statements best reflects the research on fat loading?

Current scientific literature does not support the notion that fat loading will enhance performance

Research involving creatine supplementation has shown it to have a positive ergogenic effect on all but which of the following?

Energy metabolism when treadmill running at 50-90 percent of VO2 max

The most popularly known method of classification of the major lipoproteins is based on the density of the lipoprotein particle. Which of the following statements is correct based on this method?

High-density lipoproteins (HDL) contain 45-50 percent protein and are associated with apoprotein A

Which of the following statements relative to cholesterol is false?

all healthy diets should contain no cholesterol at all

Research suggests that creatine supplementation is MOST likely to enhance performance in which of the following types of physical performance tasks?

high intensity exercise lasting 6-30 seconds

The form by which cholesterol is transported in your blood may be related to the development of atherosclerosis. In general,

high levels of high-density lipoproteins, which act in a process known as reverse cholesterol transport, appear to lower the chances of developing atherosclerosis.

All of the following are true physiological functions exhibited by protein EXCEPT

it is the major energy source during exercise.

Nitrate may be found in:

leafy greens

Which of the following has the least amount of dietary protein?

one orange

HMB supplementation appears to offer the greatest benefit to:

resistance trained individuals

Research suggests that protein may be a significant source of energy during

the latter stage of prolonged endurance exercise, when protein could contribute up to 15 percent of the total energy cost.

Put the foods in order by cholesterol content per serving from greatest (1) to least (4).

1. Egg 2.Shrimp 3.Cheese 4.Milk

The recommended protein intake for an individual trying to gain muscle mass through strength training is ________ grams of protein per kilogram body weight.

1.6-1.7

In which of the following athletic events would fat assume a more important role as an energy source for the muscles?

10 mile swim (4.5 hours)

Regina is trying to cut back on her fat intake to help reduce total calorie intake and promote gradual weight loss. If she follows an 1,800-calorie meal plan and wants to achieve the Acceptable Macronutrient Distribution Range recommendation of total fat being between 20-35% of calories, how many grams of fat per day should she be eating?

40-70 grams of fat per day • AMDR for fat is 20-35% of calories: 1,800 calories X 0.2-0.35 = 360-630 kcal from fat • 360-630 kcal from fat divided by 9 kcal per gram fat = 40-70 grams fat per day

Since beginning college, Lisa has put on about thirteen pounds. She is learning in her health science class that excess calories contribute to weight gain. One recommendation her instructor made for weight loss is to choose foods that have a low percentage of total calories coming from fat. If a one-half cup serving of her favorite ice cream has 310 calories and 20 grams of fat, what percentage of total calories in the ice cream come from fat?

58% of calories in this food are from fat.

If Tomas is a healthy 24-year-old male who weighs 166 pounds, how many grams of protein per day should he have to promote protein equilibrium? (One kilogram = 2.2 pounds.)

9

To improve his overall strength, Anthony has been weight lifting in addition to running. He is now focusing on the nutrient mix of his post-weight lifting recovery snack. Which snack is ideal for recovery after weight-training and why?

A sandwich made with bread and lean turkey is ideal because the carbohydrate/protein mix enhances the muscle-building effect of activity

Some people mistakenly believe that eating more protein increases muscle mass. While protein as a component of a recovery snack can help rebuild muscle, it is only repetitive stress on the muscles through exercise that increases muscle mass. Excessive protein intake can actually be harmful. Check all of the following that are possible consequences of excessive protein intake:

All -Excessive protein can increase urine production and dehydrate the body. -Excessive protein can lead to kidney stones in people with a history of this or other kidney problems. -Excessive protein can displace carbohydrate intake, leading to insufficient carbohydrate, which can increase fatigue. -Excessive protein intake can increase calcium loss somewhat in the urine.

Which of the following is true for exercise when fat is the energy source?

All of the answers are correct. -During rest, most of the energy needs of the body are met by the supply of plasma FFA to the cells. -Hormones, such as epinephrine, are secreted during exercise, activate HSL, and these stimulate the release of FFA into the blood. -During high-intensity exercise, 75 percent of the total energy cost is derived from carbohydrates, while the other 25 percent or less is derived from fat.

There are thirteen amino acids that cannot be manufactured in the body.

False

Which of the following statements concerning carnitine is NOT supported by current research?

Most reviewers believe chronic supplementation will enhance prolonged aerobic endurance performance

Which lipid dietary component appears to be most likely to cause an increase in serum cholesterol and the development of atherosclerosis?

Saturated and trans fats

The protein isolated from which of the following plant foods is most comparable to animal protein?

Soybeans

Lisa is a college student with a strong family history of heart disease. She knows that in order to reduce cardiovascular disease risk she should lower her intake of dietary fat. Which lipid is the primary source of dietary fat in our diets?
