Correct Answers.
Muscle proteins synthesis is controlled in large part by an enzyme called mTOR. Indicate
whether the condition below would increase mTOR activity, decrease mTOR activity, or have
essentially no change: eating high fat meal - Answer Decrease
Muscle proteins synthesis is controlled in large part by an enzyme called mTOR. Indicate
whether the condition below would increase mTOR activity, decrease mTOR activity, or have
essentially no change: increasing pre-workout protein intake from 30g to 50g - Answer
Essentially no change
Muscle proteins synthesis is controlled in large part by an enzyme called mTOR. Indicate
whether the condition below would increase mTOR activity, decrease mTOR activity, or have
essentially no change: Eating high diet in leucine - Answer Increase
Muscle proteins synthesis is controlled in large part by an enzyme called mTOR. Indicate
whether the condition below would increase mTOR activity, decrease mTOR activity, or have
essentially no change: Completing endurance exercise after strength training - Answer
Decrease
T/F: The scientific literature shows conclusively that post exercise ice therapy and massage
therapy significantly reduce delayed onset muscle soreness (DOMS) - Answer False
T/F: during a maximal sprint, the muscles will run out of oxygen and the anaerobic energy
system will be activated - Answer False
T/F: A 100 m sprinter start slowing down after about 40 m due to depletion of PCr in the muscle
- Answer True

T/F it is possible for RER to go above 1.0 during certain types of exercise - Answer True
T/F Joe's vertical jump increased by 20 cm with 16 weeks of strength and plyometric training. A
portion of the improvement is due to training causing conversion of a substantial number of his
ST fibers to FT fibers - Answer False
T/F lactate is a fuel that can be used by the heart or non-exercising skeletal muscle to produce
ATP - Answer True
, T/F A strength training program were you left one set of 90% of your one rep max to failure will
produce a greater rate of muscle proteins synthesis then lifting one set of 30% of your one rep
max to failure - Answer False

fat? - Answer Resting
During an all out sprint which muscle fiber type is going to have the fastest rate of lactate
production - Answer FTx
What is the primary metabolic purpose of converting pyruvate to lactate - Answer to recycle
the cofactor NADH+ so that glycolysis can continue to produce ATP
Which of the following people would most likely have the highest absolute VO2 max - Answer
6'4 320lb Lineman from the Indianapolis Colts football team
When doing an isometric contraction - Answer Slow twitch and fast twitch fibers produce
the same amount of force per square mm
Which muscle fiber type has the smallest oxidative capacity - Answer Type IIx

As an individual increases their workload during an exercise about which of the following
statements are true - Answer The rate of lactate appearance increases in the rate of lactate
disappearance increases
