1. Aerobic Training
Module 4- Training

2. Aerobic Training
Activities are of low to moderate intensity and of moderate to long duration
ATP production during this type of exercise primarily involves the oxidative system
However, recall oxygen debt
Glycolysis is still breaking down glucose/glycogen to be used in the Krebs cycle and electron transport system (aerobic glycolysis)
Primarily uses type I muscle fibers but type II fibers will be recruited if intensity is increased are duration becomes long

3. Acute Changes of Aerobic Training
Increased cardiac output (both heart rate and stroke volume)
Oxygen uptake increases
Blood pressure increases (blood is diverted to working muscles)
Minute ventilation increases (both tidal volume and breathing frequency)
Oxygen difference between arteries and veins increases

4. Structural Adaptations of Aerobic Training
Increased:
Size of left ventricle chamber
Total blood volume
Capillary density
Myoglobin content
Aerobic enzyme activity

5. Functional Adaptations at Rest of Aerobic Training
Increased stroke volume
No change or slight increase in cardiac output
No change in:
Tidal volume
avO2 difference
No change or slight decrease in systolic and diastolic blood pressure
Decreased:
Heart rate
Breathing rate

6. Functional Adaptations during Submaximal Exercise of Aerobic Training
Increased:
Stroke volume
Tidal volume
No change or increase in avO2 difference
No change or decrease in:
Cardiac output
VO2
Decreased:
Heart rate
Breathing rate

7. Functional Adaptations during Maximal Exercise of Aerobic Training
Increased
Stroke volume
Cardiac output
Breathing rate
Tidal volume
avO2 difference
Maximal oxygen uptake
No change or slight decrease in heart rate
Slight decrease of systolic and diastolic blood pressure
