Document Summary
Smoking increases reliance on cho during exercise. There is actually less adaptation in pulmonary structure and function than in cardio and neuromuscular systems with aerobic exercise. Healthy individuals actually voer breathe at higher levels of o2 consumption. Produces decreased alveolar pco2 and increased po2. At max exercise there usually is a breathing reserve. Ve at vo2max equals only 60-85% of maximal voluntary ventilation (mvv) Ventilation in healthy individuals is not the limiting factor in exercise. For endurance athletes the pulmonary system may lag behind the highly developed cardiovascular and aerobic muscular adaptations to training. Exercise induced arterial hypoxemia (eih) may occur in elite endurance athletes. Inequalities in ventilation perfusion ratio within the lungs. Shunting of blood flow by passing alveolar capillaries. 3. failure achieve end capillary po2 equilibrium. Acids- dissociate in solution to release h+ Bases- accept h+ to form hydroxide (oh-) ions. Chemical buffers: consists of a weak acid and the salt of that acid.
