Facts

Question 1

Simonson et al 2014

Answer 1

Individuals living in high altitudes destinations have higher Hb-O2 affinity

Question 2

Altitude training main aim

Answer 2

Elicit adaptations which may offset the reductions in oxygen within the cascade due to altitude

Question 3

Hypoxia Chamber

Answer 3

Hypoxia chamber can simulate conditions to artificially train athletes

Question 4

Altitude effects the arterial % of oxygen saturation in blood

Answer 4

At sea Level O2 saturates 97% of blood
At 30,000 ft O2 saturation is around 24%

Question 5

Bohr shift

Answer 5

Right shift in the curve occurs due to altitude and decreases affinity for O2 retention.
Beneficial to train in order to creat a left shift in curve to extend the plateau at which oxygen is retained for

Question 6

Key adaptations to low levels of oxygen

Answer 6

-hypoxia ventilatory response HVR
- altitude increase haematocrit
- hypoxia increased production of EPO
Increased haemoglobin mass

Question 7

Bonetti and Hopkins 2009
Meta analysis

Answer 7

Positive effects for endurance performance were only show with LHTL (4%)

Question 8

Negatives of hypoxia

Answer 8

-reduction in maximal power
-reduction in oxygen flux during mitochondrial systems
-reduction in work capacity
-peak response to endurance training is blunted

Question 9

Chapman et al 2014

Answer 9

Two weeks after altitude training only 2085m and 2454m elevations showed significant improvements in time trials

Question 10

Optimal height

Answer 10

Between 2000-3000m

Question 11

LHTL

Answer 11

1-2% improvements in performance
