Nope.
Adaptations of the heart, lungs, blood, and arteries happen, no matter what type of exercise you did to make those adaptations happen.
Aerobic muscle adaptations happen when the muscle gets worked. Hypertrophy, capillarization, mitochondria function and growth. Those are obviously activity specific.
