Test Final- Resistance adaptations

Question 1

Acute adaptations on muscle protein synthesis

Answer 1

-increase as much as 150%
- can last up to 48h
-

Question 2

Neural adaptations (2 main)

Answer 2

-1st 6 weeks

1. increased muscle activity- ability to recruit MU
   - altered MU firing rate (synced)
2. Reduced neural inhibition- decrease coactivation of antagonists
   - increased activation of synergistic muscles

Question 3

Hypertrophy vs hyperplasia

Answer 3

hypertrophy- increasing muscle fibre size

hyperplasia- increasing muscle fibre number

Question 4

Fibre type alterations

Answer 4

result in gains in cross sectional area

11x->11a

Question 5

Cardio changes

Answer 5

• as much stress on CV system as ET

- Stims muscle capitalization

Question 6

Metabolic changes

Answer 6

• Pcr increases

- increased content +function of PFK

Question 7

Physiological effects of detraining

Answer 7

• VO2 max down 8% in 6days
• SV and BV lower quick
• AVO2 diff lower later

Question 8

How is protein created

Answer 8

-Primary signal sets off specific sequence of events. This then signals transcription/ translation which builds mrna which codes for pro.

Question 9

Secondary messages mTor and AMPK

Answer 9

mTOR- key for muscle hypertrophy

AMPk- From ET can inhibit mTOR, increases glucose uptake, FA oxidation, mitochondrial biogenesis

Question 10

Signal transduction pathway (signal/ sensor/ kinase)

Answer 10

signal- PH, O2

Sensor- Cell membrane receptors

Kinase- Activates
Phosphates-deactivates
