Acute Responses Flashcards
(19 cards)
Tidal Volume
How much air is inspired or expired in 1 breath
Respiratory Rate (RR)
The number of breaths taken in one minute
Plateau
To reach a period or level where no change is observed.
Ventilatory Threshold
The point where ventilation increases at a non-linear rate.
Diffusion
The movement of molecules from an area of high concentration to low concentration
Cardiac Output
Amount of blood pumped out of the heart in 1 minute
Stoke Volume (SV)
The amount of blood ejected by the left ventricle per beat
Heart Rate (HR)
The number of times the heart beats per minute
Systolic Blood Pressure
Pressure in the arteries following contraction of ventricles as blood is pumped out of the heart
Diastolic Blood Pressure
Pressure in the arteries when the heart relaxes and ventricles full with blood
Vasoconstriction
A decrease in the diameter of a blood vessel, resulting in a decrease in blood flow to the area supplied by the blood vessel.
Vasodilation
To increase in the diameter of the blood vessel resulting in a increase in blood flow to the area by the blood vessel
Arteriovenous oxygen difference (a-Vo2 diff)
Difference in oxygen concentration in the arterioles compared with the venules
Motor unit
A motor neuron and muscle fibres it stimulates
Adenosine Triphosphate (ATP)
A chemical compound made up of adenosine and two phosphate molecules
Adenosine Diphosphate (ADP)
A chemical compound made up of adenosine and two phosphate molecules
Phosphocreatine (PC)
A chemical fuel consisting of a bound phosphate and creative molecule. Also known as creatine phosphate and CP
Lactate Inflection Point (LIP)
The exercise intensity beyond which lactate production exceeds removal, sometimes referred to as the lactate threshold.
Ventilation
How much air is breathed in or out in 1 minute
