Answer |
| carotid bodies |
monitor the state of arterial blood just before it perfuses the brain |
| neurogenic factors for ventilatory control: |
1)cortical influence2)peripheral influence(pg. 297) |
| ventilatory equivalent |
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 |
| alkaline reserve |
buffer reserve |
