Altitude Training Altitude Problem Partial pressure of gas
Altitude
Training @Altitude • Problem… • Partial pressure of gas is reduced in direct proportion to increase in altitude – Decrease PO 2 leads to decrease performance b/c O 2 transportation is hindered
How is Acclimatization Achieved? • Adaptations to environment – Initially: plasma volume decreases meanwhile the # of RBC per unit of blood increases – After Adapting: normalized plasma levels and increases in RBC # which results in increase total blood volume.
Three Important Adaptations • 1) Respiratory: Pulmonary Ventilation increases @ rest and during exercise; you ventilate greater volumes of air at altitude because air is less dense. • 2) CV: @ end of first few weeks blood begins to normalize • Blood volume increases after 2 weeks which leads to increase in O 2 carrying capabilities=hemoglobin • 3) Metabolic: produce more lactic acid
High Altitude Basics • After 1 -2 d. may see Altitude Sickness – Dehydration, nausea, vomiting, difficulty breathing, insomnia – Can develop pulmonary and/or cerebral edema • 24 hrs. = Altitude sickness does not typically set in
Bears vs. Broncos
Bears vs. Broncos • • 4 -6 weeks ideally to acclimatize 2 -3 weeks minimum OR… Arrive within 24 hours of game
Response to Exercise @ Altitude • VO 2 Max…can’t attain same levels or potential • Can’t train L. A. buildup because not reaching threshold
4. What are Altitude Parameters? • High=More than 7, 500 feet above sea level • Moderate/Low=5, 000 feet above sea level
Live vs. Train • What should you do? – H/H= Lactic Acid production. LT comes much faster – H/L=Live @ high altitude and train at lower elevations – L/H=Can’t train at truest VO 2 MAX
