Dj! Thanks for posting!

How does the heart adapt differently with an identical 150HR on high resistance versus high cadence?
Does higher resistance or higher cadence build a larger heart and stroke volume?

[@8WOTV]

There are a host of different adaptations based on what's causing the heart rate to go higher. When it comes to lifting weights, it's driven by much higher blood pressures and very high levels of sympathetic hormones and it's for relatively short periods of time. This is much different than slower, longer duration endurance type activities.
The hearts of an endurance athlete and a powerlifter will look very different for this reason. Endurance athletes have the highest stroke volume

Thank you for that explanation. Its really difficult sorting through the research since HIIT often claims its superior for the heart and aerobic fitness which I know is not true.
I am trying to figure out the maximum heart rate, cadence, and resistance to build the largest heart and stroke volume.
What is the optimal balance between heart rate, cadence, and resistance to build the largest heart size and stroke volume?
How does the heart adapt differently if he had increased cadence to reach 150HR rather than increasing resistance to reach an identical 150HR?

@@bmp713 There is really not "optimal" balance in terms of managing all those variables because each person is different. For building stroke volume and overall VO2, resistance is much less important than duration. Endurance athletes have the overall highest stroke volume and their training almost always ends up around 80% low intensity and 20% higher intensities. If you stick to that rough balance, you'll be on the right track. Forget about using high resistance to build stroke output, that can develop muscular endurance, but it's not what you want for the heart.

From watching your videos and interviews, and doing research it seems 130-150HR is generally the range for pumping the most blood each beat with cyclic movements rather than high resistance. Thats why I am confused by this video where he increases resistance and slows cadence instead of reaching 150 by increasing speed. It seems that the more often muscles can pump more blood through the heart while staying in that 130-150 range would maximally fill and stretch the heart.
Does that mean the fastest cadence that maintains 130-150HR would fill the heart fully and maximally stretch the left ventricle?
Compared to reaching 150 by adding resistance in the video.
Thank you for all the content you do on this subject. It drives me crazy how much debate there is between HIIT and LISS.
All I am trying to do is develop the largest and strongest heart I can to treat a heart condition.
