Chapter 8-Cardiorespiratory Fitness Training

Question 1

Cardiorespiratory fitness

Answer 1

The ability of the circulatory and the respiratory systems to supply oxygen-rich blood to the skeletal muscles during sustained physical activity

Question 2

The initial exercise prescription should reflect:

Answer 2

• the initial fitness level of the client
• fitness assessment results
• any significant risk factors or health limitations to exercise

Question 3

General warm up

Answer 3

Low-intensity exercise consisting of movements that do not necessarily relate to the more intense exercise that is to follow.

Question 4

Specific warm up

Answer 4

Low-intensity exercise consisting of movements that mimic those that will be included in the more intense exercise that is to follow

Question 5

What are three benefits of the warm up period?

Answer 5

• increased heart and respiratory rate
• increase tissue temperature
• increase psychological preparation for higher training intensities.

Question 6

Effects of “increased heart and respiratory rate”

Answer 6

• increases cardiorespiratory system’s’ capacity to perform work
• increases blood flow to active muscle tissue
• increase the oxygen exchange capacity

Question 7

Effects of “increased tissue temperature”

Answer 7

• Increases rate of muscle contraction
• increases efficiency of opposing muscle contraction and relaxation
• increases metabolic rate
• increase the soft tissue extensibility

Question 8

Effect of “increased psychological preparation”

Answer 8

Increases the mental readiness of an individual

Question 9

Benefits of a cool down include:

Answer 9

x Reduce heart and breathing rates
x Gradually cool body temperature
x Return muscles to their optimal length-tension relationships
x Prevent venous pooling of blood in the lower extremities
x Restore physiologic systems close to baseline
