- Effects of altitude on the body
- Conditions at altitude
- Decreased barometric pressure
- Percentages of gasses remain the same
- The Partial Pressure of each gas decreases
- Movement of gasses
- Move from high conc to low conc
- The greater the gradient the faster the movement
- Partial pressure of oxygen in blood is 40mmhg
- mmhg = millimetres of mercury
- The greater the altitude the slower the movement of gasses
- A reduction in haemoglobin saturation causes...
- Increase in breathing frequency
- Decrease in blood volume
- Stroke volume decreases
- Increase in heart rate
- Maintain cardiac output
- Reduction of aerobic capacity
- Reduces intensity and duration of exercise
- Acclimitising
- Needs to be done for altitude events
- 3-5 days for 1000-2000m
- 1-2 weeks for 2000-3000m
- 2-3 weeks for 3000-5000m
- 4+ weeks for 5000m+
- Benefits
- Increase RBC production
- Breathing rate stabilises
- SV and Q reduce as O2 extraction is more efficient
- Reduced effects of altitude sickness
- Needs to be done for altitude events
- Types of altitude training
- LLTH- live low train high
- LHTH- live high train high
- LHTL- live high train low
- Benefits
- Increased concentrationof RBC
- Increased concentrationof haemoglobin
- Enhanced O2 transport
- Negatives
- Expensive
- Sickness
- Difficult to train with lack of O2
- Benefits can be lost
- Conditions at altitude
- For every 1000m above 1500m VO2 max decreases by 8-11%
