ACCLIMATIZATION. a. Successful acclimatization depends on three factors: (1) Degree of hypoxic stress (i.e. altitude) (2) Rate of onset of hypoxic stress (i.e. ascent rate) (3) Individual Physiology (i.e. genetic differences between individuals) b. Physiologic Changes:
(1) Respiratory - Hypoxic Ventilatory Response (HVR) - Hypobaric hypoxia - Triggers carotid body - Central respiratory center stimulated - Ventilatory rate increases HVR can be measured: - "High" leads to successful acclimatization and superior performance. - "Low" tends to be found in victims of altitude illnesses. - HVR can be influenced by depressants (ETOH) and stimulants. (caffeine), and progesterone. - May be negatively influenced by physical conditioning. 42
