Chapter 6 - Adaptations to Aerobic Endurance Training Programs Flashcards
cardiac output is __________.
amount of blood pumped out by the heart in liters per minute
stroke volume is ___________
the quantity of blood ejected with each heart beat
cardiac output equation is ________ x _________.
stroke volume X heart rate
maximal heart rate equation
220- age in years.
1 MET = how many ml of oxygen per kg body weight per minute?
3.5
fick equation: V02 = ____ X _______
q (cardiac output); a V02 difference.
arteriovenous oxygen difference is ____________
the difference in oxygen content between arterial and venous blood
tidal volume is the total amount of air ______ and ________ with each breath.
inhaled; exhaled
functional unit of the pulmonary system where gas exchange occurs:
alveoli
bradycardia
slow heart rate
what is myoglobin?
a protein that transports oxygen within the cell
Two adaptation that occur at higher altitudes
Hyperventilation
Increased cardiac output at rest due to higher heart rate
hyperoxic breathing:
breathing oxygen enriched gas mixtures during rest periods or following exercise
blood doping (mechanism)
running your blood through EPO and then shuttling it back into your body.
A 17 year old high school cross country runner has been training aerobically for 6 months in preparation for the upcoming season. Which of the following adaptations will occur in the muscle during that time.
increased concentration of glycolytic enzymes
hyperplasia of type II fibers
transformation from type I to Type II fibers
hypertrophy of type I fibers
hypertrophy of type I fibers
