Adaptations to Training

Adaptations are changes that occur happen due to either short or long term training. Short term adaptations are immediate, usually including of increased heart rate. long term adaptations can conclude of aerobic endurance.

Increased Stroke Volume

As a person trains their heart enlarges as a result of this it will have an increased stroke volume. This describes the amount of blood that can be pumped from the heart’s ventricles in one contraction. Therefore, at rest the heart is able to pump more blood in one beat than in a person who is less aerobically fit. Stroke volume is defined as the volume of blood ejected from a ventricle with each beat of the heart. Long-term aerobic exercise increases the size and efficiency of the heart and the stroke volume, which can be a slower heart rate.
