Stroke Volume
Definition
Stroke volume is the amount of blood ejected by the heart in one contraction. It's an important measure in understanding cardiovascular health and fitness, as more efficient heart function can mean better overall endurance and performance.
Scientific / Technical Definition
Stroke volume refers to the volume of blood pumped from the left ventricle of the heart with each beat. It is a critical component of cardiac output, which is calculated by multiplying stroke volume by heart rate. Measuring stroke volume helps assess the heart's efficiency and can indicate cardiovascular health.
Benefits
- Improved stroke volume can enhance cardiovascular efficiency and endurance.
- Higher stroke volume can reduce resting heart rate, indicating a more efficient heart.
- It aids in better oxygen delivery to muscles during exercise, improving performance.
Examples
- In elite athletes, higher stroke volume and lower heart rates are common during both rest and exercise, indicating a well-adapted cardiovascular system.
Additional Information
- Importance: Stroke volume is important in determining an individual's cardiac output, which affects physical performance and overall heart health.
