Frequently Asked Questions

SEO‑focused answers about capillary density

What is capillary density?

It is the number of small blood vessels per muscle fiber or area, improving oxygen delivery and waste removal.

How fast does capillarization occur?

Structural changes emerge over weeks; consistent aerobic training accelerates remodeling.

What sessions stimulate capillaries?

Zone 2 volume, long runs/rides, and tempo efforts promote angiogenesis.

Does HIIT help?

Intervals complement volume but chronic aerobic load is the main driver of capillary growth.

How does density affect endurance?

More capillaries shorten diffusion distance, improving O₂ delivery and lactate clearance.

Is there a limit?

Gains plateau; this tool caps at ~25% in the given horizon to reflect diminishing returns.

How to support angiogenesis nutritionally?

Adequate iron, nitrates (beet), polyphenols, and overall energy availability help.

Does altitude change density?

Chronic hypoxia may aid vascular remodeling but requires careful load management.
