In healthy older adults, doing aerobic exercise before resistance training leads to a smaller increase in blood flow to the thigh muscle after lifting weights, which may reflect more efficient energy use by the muscle.

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

Randomized Controlled Trial

Human

2025 Sep

Before doing weight training, older adults who did aerobic exercise like cycling developed more tiny blood vessels in their muscles. This meant their muscles didn’t need as much blood flow during weightlifting to get the oxygen they needed—so the lower blood flow wasn’t a problem, it was a sign their muscles got better at using oxygen.

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.

After six weeks of light weightlifting with blood flow restriction, older adults got stronger and could do more repetitions before getting tired.

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.
