1.1e - Effects Of Exercise Flashcards
Aerobic energy production definition
Takes place in the presence of oxygen
Aerobic energy production formula
Glucose + oxygen
—>
Energy + Carbon Dioxide + Water
What is aerobic exercise?
Low/moderate intensity for a sustained period of time.
Aerobic exercise sporting examples?
Marathon Runner
Endurance Cycling
How are aerobic energy by products released?
Through sweat and CO2 exhaled.
Anaerobic energy production definition
Takes place in the absence of oxygen
Anaerobic energy production formula
Glucose
—>
Energy + Lactic Acid
What is anaerobic exercise?
High intensity
Powerful & Quick muscle contractions
Anaerobic exercise sporting examples
100m sprinter
Long Jump
What is anaerobic energy by product?
Lactic acid, which builds up and causes fatigue
What are the 4 long term effects of exercise on the respiratory system?
1) Better blood supply around the alveoli
2) Increased number of alveoli
3) Increased strength of diaphragm and intercostal muscles
4) Increase in vital capacity
What is the benefit of increased amount of alveoli?
- better gaseous exchange
- better oxygen delivery
- better waste product removal
What is the benefit of a stronger diaphragm and intercostal muscles?
- Increased tidal volume
- Increased vital capacity
What are the 6 long term effects of exercise on the cardiovascular system?
1) Cardiac hypertrophy
2) Increased elasticity in the walls of arteries and veins
3) Increased number of red blood cells
4) More efficient vascular shunt
5) More capillaries
6) Lower blood pressure at rest
What is cardiac hypertrophy?
Increase size of heart due to training.
