Heart Stroke Volume (Z2)
Today, I want to delve into effort zone Z2 (endurance or Heart Stroke Volume – HSV). For some reason, this zone is often neglected among amateurs, just like Z3. But why is it so important?

Today, I want to delve into effort zone Z2 (endurance or Heart Stroke Volume – HSV).
For some reason, this zone is often neglected among amateurs, just like Z3. But why is it so important?
Well, I’m passionate about power and efficiency, and therefore, Heart Stroke Volume (HSV) plays a key role in this topic. As we’ve discussed previously, mitochondria generate energy for our muscles. To produce energy, mitochondria use oxygen provided by the bloodstream.
Magnificently, our mission is to provide maximum blood volume to mitochondria with minimal heart pumps (beats). Therefore, the HSV fully responds to our task.
Throughout our routine LSD (long slow distance) activity or prolonged aerobic exercise training, stroke volume increases, resulting frequently in a lower resting heart rate. It also increases heart size, heart elasticity, contractility force, and the duration of contraction.
Therefore, to gain power, efficiency, or simply become stronger, you must incorporate Z2 training into your schedule.
If you’re interested in more detailed data, ask your coach or physiologist.
Stay tuned!
