Training for Anaerobic and Aerobic Power

Question 1

The overload for certain aerobic activities must accomplish which two objectives

Answer 1

-Engage the appropriate muscles
-Provide an intensity at a level sufficient to stress the cardiovascular system

Question 2

What 3 factors need to be manipulated to achieve appropriate overload?

Answer 2

-Frequency
-Intensity
-Duration

Question 3

Overloading specific muscle groups with endurance training does what two things?

Answer 3

-Increases aerobic power
-Enhances performance

Question 4

When someone increases the oxidative capacity of a muscle, what does that mean in terms of ATP generation?

Answer 4

It means the muscle can increase the capacity to generate ATP aerobically before lactate accumulation onset.

Question 5

What are 3 metabolic adaptations to anaerobic training?

Answer 5

-Increased levels of anaerobic substrates (ATP, glycogen, PCr)
-Increased quantity and activity of enzymes that control the anaerobic phase of glucose catabolism
-Increased capacity to generate and tolerate high levels of blood lactate during all-out effort

Question 6

Who has thicker ventricular walls–resistance-trained or endurance athletes?

Answer 6

Resistance-trained

Question 7

True or False: Left ventricular mass changes with the increase and decrease in aerobic activity.

Answer 7

True

Question 8

What happens to stroke volume for an endurance athlete?

Answer 8

It increases during rest and physical activity regardless of age or gender.

Question 9

When is the greatest stroke volume increase?

Answer 9

From rest to moderate intensity.

Question 10

At what percentage of VO2max does maximum stroke volume occur?

Answer 10

Between 40-50%.

Question 11

Does VO2max raise the body’s oxygen requirement?

Answer 11

Yes.

Question 12

How does reduced oxygen consumption by the ventilatory musculature enhance endurance?

Answer 12

-Reduces fatiguing effects on ventilatory musculature.
-Any oxygen freed from use by the respiratory musculature becomes available to the active locomotor muscles

Question 13

Is relative intensity over absolute intensity preferred?

Answer 13

Yes. It’s more based on someone’s physiological systems

Question 14

At what percentage of intensity do you regularily need to maintain to improve aerobic capacity?

Answer 14

55-70% maximum.

Question 15

What is the blood lactate concentration to produce recommended training intensity?

Answer 15

4-mM

Question 16

What is an advantage of training at the lactate threshold?

Answer 16

Tests the capacity of active muscles to sustain steady-rate aerobic metabolism
