Answer 1

HR, SV, TPR

Question 2

what increases during acute aerobic exercise

Answer 2

diameter of vessels feeding active skeletal muscle
SBP
afterload

Question 3

what changes with endurance training

Answer 3

SV max - increases

Q max - increases

BP max - increases

Question 4

what is overreaching vs. overtraining syndrome

Answer 4

overreaching: short-term performance decrement, easily recoverable - due to excessive training frequency, duration and/or intensity

overtraining syndrome: serious clinical condition, that involves perturbations of multiple body systems

Question 5

what muscle fibers are most overloaded during endurance training?

Answer 5

SO - endurance training leads to hypertrophy of SO fibers only

Question 6

which muscle fiber conversions would happen in response to endurance training

Answer 6

FG -> FOG

Question 7

central vs. peripheral adaptations

Answer 7

central adaptations:
affect O2 delivery
- oxygenating blood
- pumping blood
- distributing blood

peripheral adaptations:
affect O2 use by muscles
- getting O2 into cells/mitochondria
- capacity for cellular respiration
