As we age there is a decrease in capillarization and an increase in anabolic resistance.
If you increase the amount of capillaries of muscles (capillarization) you’ll more quickly get more blood flows, oxygen, and nutrients to those muscles. You’ll be able to engage in physical activities longer.
As we age our body down-grades its ability to synthesize protein (anabolic resistance). This protein is necessary to maintain muscle.
How can you reverse anabolic resistance and increase capillarization?
“Resistance-type exercise training can effectively augment skeletal muscle fiber capillarization in older men. The greater capillary supply may be an important prerequisite to reverse anabolic resistance and support muscle hypertrophy during lifestyle interventions aiming to support healthy aging.
