Question 1

Weight in hand sensed by fibers to move said weight

Answer 1

mechanical tension

Question 2

Idea that lower loads align more metabolites for growth

Answer 2

metabolic stress

Question 3

Muscle Damage

Answer 3

not necessary for hypertrophy

Question 4

Metabolic Stress mechanisms

Answer 4

feel the burn, getting a pump, higher reps, shorter rest

Question 5

Muscle Damage mechanisms

Answer 5

eccentrics, full ROM, novelty

Question 6

Mechanical Tension mechanisms

Answer 6

progressive overload (system force production) & mind-muscle connection (muscle force production)

Question 7

Base of hypertrophy period

Answer 7

mechanical tension

Question 8

What contributes to fatigue?

Answer 8

Metabolites

Question 9

Motor unit fatigue

Answer 9

one after the other until the complete end of the set for overall growth

Question 10

Studies didn’t give opportunity for growth beyond what is maximal due to

Answer 10

BFR and high load RT

Question 11

Letting pressure go during BFR rest periods releases

Answer 11

metabolites

Question 12

Post-exercise BFR study purpose

Answer 12

determine whether BFR at conclusion of set could augment muscle hypertrophy

Question 13

End product of glycolysis

Answer 13

Lactate

Question 14

Does lactate accumulate?

Answer 14

Yes

Question 15

ATP Hydrolysis

Answer 15

ATP + H2O <– ATPase –> ADP + Pi + H

Question 16

Post-exercise BFR study hypothesis

Answer 16

applying BFR post-exercise would not induce greater hypertrophy

Question 17

Post-exercise BFR pilot study looked to see if there were ______ with what protocol?

Answer 17

metabolites; 70%, one set to failure, cuff inflated as soon as failure begins

Question 18

Post-exercise BFR study results

Answer 18

cuff attenuated growth, metabolites did nothing, more discomfort in cuff group

Question 19

Anabolic benefits of venous BFR study suggested that

Answer 19

swelling could be anabolic

Question 20

Fluid into the muscle cell could bring in

Answer 20

proteins/nutrients

Question 21

Elevated plasma lactate levels via exogenous lactate infusion study purpose

Answer 21

investigate whether lactate could exhibit cell signaling properties in combo with contractile activity

Question 22

Elevated plasma lactate levels via exogenous lactate infusion study design

Answer 22

two sessions of unilateral leg extension with simultaneous venous infusion of sodium lactate or isotonic saline; followed by 3 warm-up sets and 6 sets at 75%

Question 23

Elevated plasma lactate levels via exogenous lactate infusion study results

Answer 23

muscle lactate and pH had drastic increases in the muscle; no difference in lactate or saline conditions

Question 24

Exercise –>

Answer 24

mTor

Question 25

mTor –>

Answer 25

S6K1

Question 26

S6K1 –>

Answer 26

increases MPS

Question 27

Elevated plasma lactate levels via exogenous lactate infusion study discussion

Answer 27

Maybe needs to be refined, or more, or injected directly into muscle; may reduce exercise while increasing lactate to see if there is a response

Question 28

Elevated plasma lactate levels via exogenous lactate infusion study limitations

Answer 28

no potential to augment due to maximal exercise protocol
