the ratio of minute ventilation to oxygen consumption
ventilatory threshold
the point at which pulmonary ventilation increases disproportionately with oxygen consumption during graded exercise
lactate threshold
the highest oxygen consumption or exercise intensity achieved with less than a 1.0 mM increase in blood lactate concentration above the preexercise level
onset of blood lactate accumulation (OBLA)
when blood lactate concentration systematically increases to 4.0 mM
2 factors that influence endurance performance in a specific exercise mode:
1)maximum capacity to consume oxygen (VO2max)2)maximum level for steady rate exercise (OBLA)
exercise-induced arterial hypoxemia (EIH)
when the potential for inequality in alveolar ventilation relative to pulmonary capillary blood flow during high-intensity exercise may compromise arterial saturation and oxygen transport capacity (pg. 307)
bicarbonate buffer
consists of the weak acid, CARBONIC ACID and its salt, SODIUM BICARBONATE
