Midterm Part 4

Question 1

What is Anaerobic Threshold

Answer 1

The exercise intensity where anaerobic energy production(glycolysis) accelerates to further supplement aerobic production

Question 2

What system is predominantly being trained during Anaerobic threshold training?

Answer 2

Mostly still your aerobic system, but this is the point where anaerobic is accelerated. Anaerobic = Oxygen system

Question 3

Is there ever a point in time when Anaerobic/aerobic systems are running independently?

Answer 3

Nope, they are ALWAYS both running

Question 4

Describe Lactate Threshold

Answer 4

expressed as a percentage of the athletes VO2 max, determines the rate of aerobic energy expenditure that can be maintained on a prolonged basis. Corresponds to the rate of aerobic energy expenditure at which lactic acid begins to accumulate in the blood stream.

Question 5

Describe “Economy”

Answer 5

Economy of movement refers to the rate of energy expenditure associate with a given rate of power output (speed of movement). ^Economy = v energy expended

Question 6

Describe Long Duration @ moderate intensity

Answer 6

• LSD (60-70%)
• Intensity should be less that LT
• 30min to 2 hours
• May constitute major fraction of training load
• not high in stress on MSK or Phsyiological systems
• induces muscle glycogen depletion and increased rate of fat metabolism

Question 7

What are basic Cardiorespiratory adaptations to exercise? (3)

Answer 7

Increased blood volume, oxidative capacity to skeletal muscle, tolerance to heat stress

Question 8

Moderate Duration and Short duration at High intensity, what are the main benefits?

Answer 8

Moderate: Train @ LT, may help to improve LT which is important for those with high VO2
Short: Increase or Maintain VO2 and improves lactate tolerance via increased buffering capacity
