Q

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

A

High haematocrit levels by occupying the rooms whilst they sleep

Q

Acclimatisation is the phase it takes to:

A

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

Q

Primary training is:

A

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

Q

Recovery lasts for:

A

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

Q

9 Benefits are:

A
  • 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

Q

13 Drawbacks are:

A
  • 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

Q

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

Q

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

A

Altered fitness levels and coordination losses while training at altitude

Q

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

A
  • Increased oxygen transport
  • improved economy
  • maintenance of breathing adaptations
