Cardiovascular Control
Slower heart rate is termed
Bradycardia
This molecule makes up a majority of earths air pressure.
Nitrogen
A major limitation of athletic performance is...
pH balance
Prolonged anaerobic training often results in what shift in capillary density?
Decrease
Heat transfer from direct contact
Conduction
On an ECG, Ventricular depolarization is indicated by...
QRS Complex
Amount of air that is entering and leaving the lungs with each breath
Tidal Volume
The point where liters of air breathed exceeds liters of O2 consumed
Ventilatory Threshold
As the body adapts to anaerobic training, Respiratory-Exchange-Ratio will do what for submaximal activities?
Increase
Term for life threatening fluid in the lungs experienced at high altitudes.
High Altitude Pulmonary Edema (HAPE)
This component of cardiac tissues anchors cells together.
Desmosomes
Our primary method of internal respiration is...
Capillary Diffusion
The amount of tension on the ventricular wall before it contracts
Preload
DD: One of the three muscular adaptations to aerobic training is...
1. Capillary Supply
2. Mitochondrial Function
3. Oxidative Enzymes
In order to maintain cardiac output in a hot environment the cardiovascular system will experience
Cardiovascular Drift
An increase in the radius of a blood vessel will do what to the resistance experienced in that vessel
Decrease
DD: Pressure of a gas will increase as the volume of the container decreases is part of what law.
Boyle’s Law of Gas Exchange
Respiration is often not a limiting factor except for elite endurance-trained athletes exercising at high intensities. These athletes can experience...
Exercise-induced arterial hypoxia
The main adaptations to aerobic performance will be these two factors
Increased Stroke Volume and A-V O2 difference
Body’s thermostat located in the brain
Preoptic-anterior hypothalamus (POAH)
The elastic nature of vessels that allows for the maintenance of blood pressure between heart beats.
Windkessel Vessels
Difference in pressure between the airway opening and the pleural surface of the lung
Transpulmonary pressure (TPP)
The following formula is derived from this Principle. (VO2 = Q• * (a-v)O2 difference)
Fick’s Principle
All characteristics of blood will increase with aerobic training, except for this one.
Viscosity
A wet-bulb globe temperature (WBGT) includes...
Convection, Radiation, Evaporation
