3.3 Flashcards
cardiovascular endurance
the ability to work the whole body for long periods of time without tiring
cardiovascular endurance is influenced by
the amount of oxygen transported to the working muscles by the heart blood and blood vessels
heart rate
the numbers of times the heart contracts per minute measured in beats per minute bpm
exercise effects heart rate
heart rate increases as the demand for oxygen in the working muscles increases
its possible to estimate your maximum heart rate y using the equation
220-age
stroke volume
the volume of blood ejected from the heart every time the ventricle contracts measured in ml
stroke volume exercise
stroke volume increases as the demand for oxygen in the working muscles goes up
training stroke volume
stroke volume increases as the ventricles become larger and the cardiac muscle becomes stronger
cardiac output
the total volume of blood expelled from the heart pre minute measured in litres per minute
how to calculate cardiac output
heart rate x stroke volume
units for cardiac output
litres
