!!! Adaptions of aerobic training

Question 1

What are the adaptations and functional effects of aerobic training on the respiratory system?

Answer 1

1. Respiratory muscles get stronger, causing
   - Increased efficiency of mechanics of breathing
   - Decreased respiratory fatigue
2. Increased surface of alveoli, causing
   - Increased external gaseous exchange

Question 2

What are the adaptations and functional effects of aerobic training on the cardiovascular system?

Answer 2

1. Cardiac hypertrophy, causing
   - Increased SV at rest and during exercise and CO at rest
2. Increased elasticity of arterial walls, causing
   - Increased vascular shunt efficiency
3. Increased number of RBC, causing
   - Increase in O2 carrying capacity
4. Increased blood plasma volume, causing
   - Lower blood viscosity aiding blood flow and venous return
5. Increased capillarisation of alveoli and SO muscle tissue fibres, causing
   - Increased gaseous exchange

Question 3

What are the adaptations and functional effects of aerobic training on the musculo-skeletal system?

Answer 3

1. SO muscle fibre hypertrophy, causing
   - Increased potential for aerobic energy production
2. Increased size and density of mitochondria, causing
   - Increased metabolism of fats
3. Increased stores of myoglobin, causing
   - Increased storage and transport of O2 to mitochondria
4. Increased stores of glycogen and fats, causing
   - Increased duration of exercise
5. FOG fibres become more aerobic, causing
   - Increased aerobic energy production

Question 4

What are the overall effects of adaptations on the cardiovascular system?

Answer 4

1. Increased blood flow and O2 transport to muscles
2. Delayed OBLA
3. Easier to perform exercise
4. Reduced onset of fatigue
5. Increased intensity and duration of performance

Question 5

What are the overall effects of adaptations on the respiratory system?

Answer 5

1. Increased volume of 02 diffused into blood
2. Delayed OBLA
3. Easier to perform exercise
4. Reduced onset of fatigue
5. Increased intensity and duration of performance

Question 6

What are the overall effects of adaptations on the musculo-skeletal system?

Answer 6

1. Increased capacity of aerobic energy production
2. Delayed OBLA
3. Easier to perform exercise
4. Reduced onset of fatigue
5. Increased intensity and duration of performance

Question 7

What are the adaptations and functional effects of aerobic training on metabolic function?

Answer 7

1. Increased activity of aerobic enzymes, causing
   - Increased metabolism of fats and glycogen
2. Decreased fat mass, causing
   - Increased lean mass
3. Decreased insulin resistance, causing
   - Increased glucose tolerance.

Question 8

What are the overall effects of adaptations on metabolic function?

Answer 8

1. Improved body composition
2. Delayed OBLA
3. Easier to perform exercise
4. Reduced onset of fatigue
5. Increased intensity and duration of performance
