Explanation / Answer

Stroke volume is the amount of blood ejected per beat from left ventricle and measured in ml/beat.Stroke volume increases proportionally with exercise intensity.In untrained individuals at rest ,averages upto 50-70ml/beat increasing upto 110-130ml/beat during intenseal activity.In general trained persons resting stroke volume averages 90-110ml/beat increases as much as possible.The cardiac output increases proportionally with exercises intensity which is predictable from understanding the response of heart rate and stroke volume to activity.The heart rate is directly involved with stroke volume and cardiac output,so if stroke volume increases cardiac output also increases.
