VO2 Kinetics
This occurs when there is a lag in oxygen consumption at the onset of exercise and is primarily due to the use of anaerobic pathways
What is oxygen deficit?
The pressure on the arterial walls during the heart's relaxation phase
What is diastolic blood pressure?
During the Queen's College Step Test, this is used to estimate VO2max
What is heart rate?
Vital Capacity + Residual Volume
What is total lung capacity?
This body fat distribution pattern refers to excess fat in the abdomen
What is android obesity?
____ and ____ have an effect on the magnitude and duration of EPOC.
What is exercise intensity and duration?
During this type of exercise, systolic blood pressure and diastolic blood pressure typically increase
What is resistance training?
This is likely to be the cause of an increase in VO2max after only 2 weeks of training
What is an increase in blood volume?
The ratio of pulmonary ventilation to oxygen consumption
What is a ventilatory equivalent?
This is an easy and accessible method of assessing an individual's health. However, it does not take into account fat mass and lean mass.
What is BMI?
Resynthesis of Creatine Phosphate and replenishment of muscle oxygen stores occur during this phase of EPOC
What is the fast phase?
This equation relates blood pressure to cardiovascular function
What is Blood Pressure = Cardiac Output x Total Peripheral Resistance
VO2 = CO x a-vO2
What is the Fick Equation?
The amount of air inspired or expired per breath
What is tidal volume?
This is the gold standard for measuring body composition
During steady state exercise, this metabolic pathway is primarily used
What is the oxidative pathway?
This equation illustrates factors that can influence increases in cardiac output
It is common for untrained individuals to reach this, during a VO2max test.
What is a VO2peak?
Exercise intensity at which there is an exponential rise in pulmonary ventilation
What is the Ventilatory Threshold?
This method of assessing body composition relies on the assumption that subcutaneous fat is proportional to total body fat
What is the skinfold technique?
This phenomenon occurs after exercise when heart rate and oxygen consumption do not immediately return back to baseline
What is EPOC?
This component of an ECG shows ventricular depolarization of the heart
What is the QRS complex?
The ability of the heart to change its force of contraction and therefore stroke volume in response to changes in blood volume/preload.
What is the Frank-Starling Mechanism?
This method of estimating ventilatory threshold plots VO2 and VCO2 during incremental exercise. The point at which the VCO2 departs from the line with a slope equal to one is the ventilatory threshold.
What is the "v-slope" method?
This method of measuring body composition uses Archimedes Principle to estimate body density.
What is Hydrostatic Underwater Weighing?
