"What physiological changes contribute to a low resting heart rate?"
To have a low resting heart rate, there are 2 key ingredients...
1/ A large, functional heart.
2/ Strong parasympathetic tone.
A heart with a large end-diastolic ("stretch") volume that is also strong enough to pump out most of the blood that it holds will take less pumps to deliver a given amount of O2 at rest.
A strong parasympathetic nervous system will dampen the need for high levels of energy & O2 when resting.
These 2 factors combined lead to a heart that beats slowly and efficiently.
In other words...
Keep up the low-intensity base training 🚴
Keep up the yoga (or whatever else you do to chill & relax) 🧘
