Recovery
Oxygen debt
total amount of oxygen required to bring body back to rest
- Oxygen needed to break down all lactic acid during high intensity anaerobic exercise
-
Lactic acid removal
- Oxygen combines with lactic acid
- Producing water, carbon dioxide and glucose
- molecules are either reused or removed
-
Long term effects
Heart - heart works harder as both HR and SV increase
- Cardiac muscle gets thicker and stronger
- Ventricle become bigger
Performance
- SV increase
- More oxygen transported to working muscle
- increase rate of energy production
- athletes work at higher intensities for longer periods
Bradycardia
- Resting HR below 60BPM
- Trained athletes have larger SV meaning heart doesn't need to beat as frequently to deliver necessary oxygen
lactic acid tolerance - regular anaerobic exercise increase tolerance to lactic acid, help remove quickly
- Athletes can work longer before fatigue kicks in
Anaerobic, Aerobic respiration
Aerobic respiration
Respiration takes place in presence of oxygen
- Oxygen combines with glucose to produce energy (ATP)
-
Characteristics
- Produce energy slowly
- Suitable for low moderate intensity
- continues producing energy over long periods of time
- suitable for long duration physical activities
Anaerobic respiration
Characteristics:
- Produces energy quickly
- Suitable for high intensity physical activities
- Fuel quickly runs out
- activity sustained for short periods
Respiration that takes place in absence of oxygen, glucose is converted into energy (ATP) Directly
-
Energy production
-
- Broken down into smaller molecules by digestive system
- Molecules are transported to the body's cells in the blood stream
- where converted to energy
Glucose - produced via digestion of carbs, coverted into (ATP) via respiration
-
