Test Final- Training Adaptations

Question 1

2 VO2 max determinants

Answer 1

1. O2 delivery to muscles

2. O2 utilization by muscles

Question 2

Criteria that suggests VO2 max

Answer 2

1. Plateu
2. reach age predicted max HR (+/-10)
3. High blood lactate (8x rest)
4. RER >1.15
5. Voluntary exhaustion

Question 3

how much % does Vo2 max go up w/ endurance training

Answer 3

15-20%

Question 4

4 factors determining SV

Answer 4

1. Volume of venous blood returning
2. Ventricular dispensibility
3. Ventricular contractibility
4. Aortic/pulmonary artery pressure

Question 5

A-VO2 diff during ET

Answer 5

Increased extraction due to capillary density and increased mitochondrial #

Question 6

T/F- Blood volume and total HBg content increase w/ training

Answer 6

T

Question 7

3 Metabolic changes in ET

Answer 7

1. Increased capacity (increased VO2, Q, AV diff, mitochondia density)
2. increased fuel storage
3. Sparing of CHO

Question 8

What fuel changes happen w/ ET

Answer 8

• increased muscle glycogen content
• increased intramuscular triglycerides stores
• more fats as fuel( glycogen sparing)

Question 9

Interval training adaptations

Answer 9

• increased aerobic metabolism
• increased glycolytic enzymes
• increased muscle buffering capacity
• increased acid/base balance
