In older adults who are healthy, muscle growth from consistent strength training is not affected by how many blood vessels are already present in the muscle before training begins.

Aerobic Exercise Preconditioning Does Not Augment Muscle Hypertrophy During Subsequent Resistance Exercise Training in Healthy Older Adults

Randomized Controlled Trial

Human

2025 Sep

Even though some people had more blood vessels in their muscles before training, everyone gained about the same amount of muscle size after doing strength exercises—so having more or fewer blood vessels doesn’t stop older adults from getting stronger and bigger muscles.

Similar Assertions

In healthy older adults around 71 years old, eight weeks of aerobic exercise increases the number of capillaries surrounding muscle fibers, with greater increases in type II fibers than type I. However, this change does not lead to greater muscle growth when followed by 12 weeks of strength training compared to strength training alone.

Doing light weightlifting with a band that restricts blood flow for six weeks can make both slow and fast muscle fibers in older people grow bigger by about 20%, even without heavy lifting.

Lifting weights for three months increases the number of tiny blood vessels in arm muscles of young men, and the growth keeps up with how much the muscle fibers get bigger.

If you're new to strength training, having more tiny blood vessels around your fast-twitch muscle fibers might help those muscles grow more when you start working out.

In healthy older adults, doing resistance exercises like weight lifting can lead to an increase in the number of small blood vessels surrounding muscle fibers, even if they have not previously done aerobic exercise.
