What is the typical average stroke volume?

The typical average stroke volume for a healthy adult at rest is approximately 70 ml. Stroke volume is the amount of blood ejected by the heart's left ventricle in one contraction. This value can vary depending on several factors such as age, body size, fitness level, and overall cardiovascular health.

Generally, the stroke volume at rest falls within a range of about 60 to 100 ml, with 70 ml being a commonly accepted average. It is a crucial metric for assessing cardiovascular health and efficiency, contributing to the overall cardiac output when multiplied by heart rate. Understanding stroke volume is important for evaluating an individual's capacity for physical activity and training adaptations, as it helps to indicate the effectiveness of the heart as a pump during exercise and daily activities.
