Even though men and women, or different cuff sizes, cause different amounts of muscle swelling in absolute terms, when you adjust for how big the muscle was to start with, everyone swells about the same — so if swelling is what triggers muscle growth, these differences might not matter.

When people do exercise with their blood flow partly restricted, men’s muscles tend to swell more in absolute size than women’s, but when you look at how much they swell relative to their starting size, men and women are about the same.

When using a thinner cuff to restrict blood flow during exercise, muscles swell more in absolute size than with a thicker cuff, but when you account for how big the muscle was to start with, both cuffs cause about the same amount of swelling.

Acute muscle swelling responses following a single resistance training session are not representative of swelling responses observed after prolonged, repeated training programs.

After a heavy leg workout, the thigh muscles get noticeably thicker due to swelling, and this lasts for at least two days.
