Altitude Flashcards
What’s altitude like at sea level
High air pressure
Normal ppO2
Muscles have full saturation of oxygen
Altitude at 1500m+
Low air pressure
Lower ppO2
Muscles have limited saturation of O2
What body does in response to altitude
CV system
More RBC
More oxygen carrying capacity
More affinity
SV increases as pump with more force
What does body to to inc RBC at altitude
EPO hormone trigger bone marrow to produce RBC
What does body do in response to altitude respiratory system
Increased frequency and depth
Diaphragm and intercostals go through hypertrophy
Breathing frequency tidal volume and minute ventilation all increase
Disadvantage of altitude
Takes time to acclimate to altitude, a week per 1000m above 2400
Body producing epo to combat lack of oxygen which can lead to altitude sickness
More EPO and RBC makes blood more viscous which can lead to stroke/heart attack
Body can’t exercise at such intensity
Solutions to problems of altitude training
Live high train low
Benefits when living more than 12 hours at altitude
Higher intensity when training lower
Has to be at least 6 weeks
