Aerobic System
| Question | Answer |
|---|---|
| Tidal Volume (TV)? | Amount of air moved in an inhalation/expiration |
| Forced vital capacity (FVC)? | Amount of air that can be forcibly exhaled after big inspiration |
| Residual lung volume (RLV) | Whats left in the lungs after maximal expiration |
| FEV 1.0 = | Force expiratoy volume in 1 second |
| Minute ventilation ? | Volume of air moved in one minute Frequency of breaths/minute * tidal volume |
| Anatomical deadspace? | Air that fills the nose, mouth, etc/OTHER ANATOMY. No gas exchange takes place |
| Physiological deadspace? | |
| Dysnpea | Shortness of breath |
| What is myoglobin? | Protein containing heme. found in muscle cells. Carries/stores oxygen |
| Chemoreceptors? | Sensory cell/organ that responds to chemical stimuli. Found in carotid artery, aorta, |
| Ventilatory threshold? | Point were pulmonary ventilation increases disproportionately with oxygen uptake during graded exercise. |
| Onset of blood lactate accumulation? (OBLA) | Implies imbalance of production and clearance. occurs at 55-65% vo2 max in healthy, 80% in trained athletes. |
| Rhythmic exercise effect on blood pressure? | Increases systolic first few minutes, then levels out. Diastolic unchanged |
| Resistance trainings effect on blood pressure? | Increase blood pressure dramatically |
| Rate pressure product (RPP) formula? | Systolic BP * HR |
| 3 factors that determine myocardial oxygen update? | *Myocardial contractility *Heart rate *tension development |
| Autonomic nervous system on HR | Sympathetic: Increases HR Parasympathetic: decreases HR |
| Factors to determine blood flow resistance | *Viscosity (thickness) *Length of conducting tube *dilation of blood vessel |
| Cardiac output? | Blood ejected per minute HR*SV |
| Stroke volume? | Blood ejected per beat |
| Stroke volume? | Cardiac output/Heart rate |
| VO2 max formula? | Max cardiac output times avo2 difference |
| Aerobic exercise on blood pressure? | Systolic - increase Disastolic - no change |
| Anaerobic exercise on blood presure? | Both increase |
| O2 utilization in heart | 70-80% taken up in heart. 25% at rest in other cells |
| Cardiac drift? (CD) | Most likely to occur in hot environment... decrease in SV |
| Function of the pulmonary system | Bring in oxygen, decrease CO2, mantain acid base balance |
| Hyperventilation? | Taking in too much oxygen, blowing off too much CO2 |
| How breathing works at rest? | Under neural control.. diaphragm contracts, reach pressure differential, diaphragm relaxes. |
| Breathing during exercise? | External intercostal/scalene assist in inspiration during exercise. |
| Hemoglobin | Caries oxygen in blood |
| PCr (Phosphocreatine) | Used to re synthesize ATP |
| Transanimation | Transfer of amine group from one molecule to another |
| Deanimation | removal of amine group from molecule |
| BMR | Basal metabolic rate. energy expended at rest |
| EPOC | Exercise post oxygen consumption... Oxygen debt |
