Massage Gun (Percussion Device)

A massage gun (percussive therapy device) drives a swappable head back and forth at high speed to deliver rapid percussion/vibration into soft tissue. It's a more targeted, less effortful form of self-massage than a foam-roller — you aim it at a specific muscle rather than rolling your bodyweight over a cylinder.

Evidence in brief: like rolling, percussion produces short-term increases in range of motion and may reduce perceived soreness/DOMS, with effects broadly comparable to foam rolling; it does not meaningfully change long-term flexibility or "repair" tissue. Useful in warm-ups (acute ROM without strength loss) and post-session for comfort (see warm-up-types, recovery-modalities).

Use notes: adjustable speed/amplitude and interchangeable heads (ball, flat, bullet, fork); glide over the muscle belly for ~30–60 s per area rather than pressing hard on one spot. Avoid bony areas, joints, the front/sides of the neck, the spine, and acute injuries.

Pros: targeted, fast, low effort, portable (battery), reaches areas hard to roll. Cons: more expensive than a roller or ball; can be misused on contraindicated areas; effects are short-term, not a cure for chronic tightness.

• Handheld percussive device; targeted self-massage alternative to foam rolling.
• Short-term ROM gains and reduced perceived soreness; effects similar to rolling, not long-term.
• Use ~30–60 s per muscle belly; multiple heads/speeds.
• Avoid bone, joints, neck (front/sides), spine, and acute injuries.

• foam-roller — comparable SMR tool (rolling vs. percussion).
• lacrosse-ball — for pinpoint trigger points.
• recovery-modalities — recovery method context.
• warm-up-types — acute ROM in warm-ups.
