Response To Exercise

Physiological Response

Factors

frequency

intensity

duration

Effects

Short Term

increase oxygen intake for muscle movement

increase carbon dioxide removal and increase in lactic acid production

increase in heart rate and stroke volume

Long Term

increase blood volume and blood plasma increase in strength to tendons and ligaments

cardiac hypertrophy: heart increases in size and wall of left ventricle gets thicker.

stroke volume at rest is higher in a trained person rather than untrained. it can pump more blood per minute increasing cardiac output when exercising

Define: physiological response is the bodies automatic response to a stimulus.

Factors

stroke volume: the count of blood ejected per beat by the left ventricle into the aorta.

age: due to size, younger children have a lower stroke volume but as we get older the stroke volume increases. same with heart rate.

training: aerobic training can decrease heart rate at rest and increase stroke volume during some workloads.
