Does Massage Increase Blood Flow — and Does That Actually Matter?

A Widely Repeated but Imprecise Claim

"Improving circulation" is one of the most frequently cited justifications for massage — but the claim conflates two very different things: blood flow in the superficial skin, and blood flow deep within the muscle belly itself.

A Real Superficial Effect, a Weaker Deep One

Measured skin blood flow does increase, visibly and measurably, during and shortly after massage — the pink or flushed appearance of treated skin is genuine evidence of this. Intramuscular blood flow is a different story: using Doppler ultrasound to measure deep muscular blood flow following massage after fatiguing isometric exercise, one study found no significant increase in intramuscular blood flow despite participants' subjective sense that the muscle felt better perfused (Mori et al., 2004).

Does the Distinction Actually Matter?

This does not mean massage is without benefit — pain relief, reduced perceived muscle soreness and improved subjective recovery have all been documented regardless of this limited deep circulatory effect, pointing once again toward neurological and psychological mechanisms as the more significant drivers of massage's clinical benefit, rather than a meaningfully improved deep blood supply to the muscle.
