Definition:

Training performed at high altitude to prepare an athlete's body to cope with a reduced supply of oxygen

1

Commonly practiced in:

Hypoxic rooms, which cause the athlete to live in high altitude and train in low

2

Hypoxic rooms helps to counteract the acuteness of high altitude training, as the athlete can maintain their:

High haematocrit levels by occupying the rooms whilst they sleep

3

At high altitude the partial pressure is reduced even though:

The air still contains the same percentage of oxygen

4

3 main stages of altitude training are:

Acclimatisation
Primary training
Recovery

5

Acclimatisation is the phase it takes to:

Acclimatise to the atmosphere, this is an immediate phase and can range from 3-10 days

6

Primary training is:

Lasts between 1-3 weeks with an aim to progressively increase the training volume until the athlete reaches the volume and intensity

7

Recovery lasts for:

2-5 days and is designed to prepare the athlete for the return to sea level and to allow the athlete to recover from the fatigue produced by high-altitude training, by gradually reducing thee training volume and intensity

8

9 Benefits are:

-Increase in RBC and haemoglobin due to triggering of EPO - enables more oxygen to be transported by the blood to the muscles
-Increased diffusion rate
-Capillarisation
-Increases myoglobin levels
-Muscles acting as buffers- reduces likelihood of fatigue
-increased oxidative enzymes in mitochondria
-increased muscle cell mitochondria
-improved aerobic performance
-increased VO2 max

9

13 Drawbacks are:

-Have to be higher than 8000ft
-Too high can lead to HAPE
-Hyperventilation
-Faster HR
-Decreased stroke volume
-RBC goes back to normal within a few days at sea level
-reduced oxygen levels = reduced training effect and possible drop in fitness
-wasting time on travel
-altitude sickness
-psychological problem of being away from home
-repeated travel = stressful
-increased fatigue due to travel
-limits to amount of EPO production

10

Upon return to sea level, there are 3 more phases:

-Positive
-Progressive return to sea-level training volume and intensity
-Fitness peak

11

Positive phase occurs during 1-4 days this is when there is an increase in the

Oxygen carrying-capacity of the blood

12

Progressive return to sea-level training volume and intensity, during which the probability of good performance is reduced, this may be due to the

Altered fitness levels and coordination losses while training at altitude

13

Fitness peak occurs 15-20 days after return to sea level and is the optimal time for Competition due to:

-Increased oxygen transport
-improved economy
-maintenance of breathing adaptations

14

Some athletes live permanently at high altitudes only returning to sea level to train or compete. This is known as the

Live high train low principle
