Bruce has really gotten into the gym and fitness as a whole
lately. As the weather begins to warm up, he finds himself working
out even more with additional outdoor workouts. He’s met a good
group of friends at the gym and is seeing his body and mood change
completely from when he walked in the door six months ago.
Bruce’s friends talk a lot about all the protein they eat and
drink. In addition to getting protein from meat, eggs, and dairy,
the guys have been making protein shakes. Gina, the lone woman in
the group, keeps telling the guys all that protein isn’t good for
their health and it’s not actually contributing to their muscle
mass like they think it is. They’re not listening to Gina, but
Bruce is. He wants to know more and doesn’t mind getting to spend
more time with Gina.
1. Protein is needed for which of the following:
|
a. integral part of structure for all organs of the human
body |
|
|
|
b. basic substances that make up enzymes |
|
|
|
c. major component of hormones |
|
|
|
d. tissue maintenance and repair |
|
|
|
e. serve as an energy source |
|
|
|
2. Bruce knows that, to bulk up, he needs to consume more
calories than he burns with all his workouts.
True or False: Because proteins are so large and complex, they
provide 9 calories per gram.
|
3. Gina tells Bruce she feels like all the guys drinking protein
shakes and eating a ton of protein all the time should have their
nitrogen balance tested by a doctor. Bruce doesn’t want to come
across as dumb, so he completely agrees with her. Gina says that
they must have a negative nitrogen balance with the way they are
building muscle.
True or False: A negative nitrogen balance is a sign that the
body is healthy and building more muscle mass.
|
4. Gina and Bruce take a look at one of the guys' premade
protein shakes. It says it has all 20 essential amino acids the
body needs. Gina laughs and says that the label can't even get the
number of essential versus nonessential amino acids right.
Which of the following correctly reflects the correct number of
essential and nonessential amino acids?
|
a. 9 essential and 11 nonessential |
|
|
|
b. 14 essential and 14 nonessential |
|
|
|
c. 2 essential and 18 nonessential |
|
|
|
d. 18 essential and 2 nonessential |
|
|
|
e. 11 essential and 9 nonessential |
|
|
|
5. Bruce is shocked to find out that Gina is a vegetarian and
has been her entire life. She’s stronger than any woman he’s ever
met and most guys. She trains hard and is seriously into martial
arts. Even more shocking is the fact she doesn’t take any protein
supplements or drink any protein shakes. Bruce wonders if this is
even possible.
True or False: Vegetarians and vegans can get enough protein from
non-meat sources to support their health and even to build muscle
mass. They do not need protein supplementation.
|
6. Gina tells Bruce that all those supplements are hype and
nothing more. They don’t even have to be proven effective.
True or False: No matter the purity of the supplement or the
product’s claim, no amino acid supplement has been shown to work
better than food for strength and muscle building.
