Under resting conditions, what is the typical stroke volume for a male weighing 70 kg?

The typical stroke volume for a resting male weighing around 70 kg is approximately 70 mL. Stroke volume is defined as the amount of blood ejected by the heart during each beat. In healthy, resting adults, this value generally ranges from 60 to 100 mL, with 70 mL being a common average for a man of this weight.

Physiological factors such as body size, fitness level, and overall health can influence this measurement. A male weighing 70 kg typically demonstrates a stroke volume that reflects a balance between cardiac output and physiological efficiency during a resting state, leading to an average around 70 mL. This is significant in the context of assessing cardiovascular health and performance, as stroke volume is crucial in understanding how effectively the heart is pumping blood to meet the body's needs.

Lower values like 50 mL may suggest issues such as inadequate cardiac function or low blood volume, whereas higher values like 90 mL or 110 mL, while possible in well-trained athletes, are less common for the general population at rest. Therefore, 70 mL is the most fitting and typical figure for this scenario.
