Massage
Evidence: limited
Manual and sports massage reliably make muscles feel better and modestly reduce perceived soreness, but the measurable effect on physical recovery and performance is small and inconsistent.
Keep it in proportion
This is one of the last few per cent, at most. It pays off only once the basics are already in place: consistent volume, sleep and adequate fuelling. Most runners gain far more from those than from anything on this page.
Manual massage, including sports massage, is among the oldest recovery practices and one of the better-liked. The evidence puts it firmly in the same place as the other passive modalities: a genuine effect on how the body feels, and little on how it measurably recovers. A meta-analysis found small positive effects on perceived recovery and soreness, with only minor and inconsistent effects on the recovery of physical performance (Poppendieck et al. 2016). In broader recovery comparisons, massage produced some of the largest reductions in delayed-onset muscle soreness and perceived fatigue, though such studies are almost impossible to blind, so part of that is the pleasant, attentive nature of the intervention itself (Dupuy et al. 2018).
That is a reason to value massage for what it reliably delivers, relaxation, reduced soreness and a sense of being looked after, rather than to expect it to speed the underlying physiology. Older mechanistic claims, such as massage “flushing out lactic acid”, do not hold up: lactate is cleared quickly regardless and is not a cause of soreness. For a runner deciding where to spend time and money, massage is a worthwhile comfort and a pleasant way to stay attentive to tight or niggling areas, but it sits below sleep and nutrition, which do the real recovery work.
”Knots” and trigger points
A large part of massage culture rests on finding and releasing “trigger points” or knots, discrete tight spots held to cause pain and tightness. The construct is shakier than its popularity suggests. The reliability of locating trigger points by feel is generally poor to at best moderate, better between two experienced therapists than between an expert and a novice, and the underlying model lacks a firm scientific basis (trigger-point review). Two practitioners often will not agree on where a “knot” is, which is hard to square with it being a precise anatomical object.
That does not make the sensation imaginary or the practice useless. Pressing on a tender, tight-feeling spot, whether by a therapist’s thumb, a foam roller or a ball, does reliably produce short-term relief and a small increase in range of motion. The reasonable position is to use targeted pressure on areas that feel tight for the comfort it gives, while treating the “knot” explanation, and any claim to be dissolving specific adhesions, as a loose metaphor rather than a mechanism. As with the rest of massage, the benefit is real but acute and largely perceptual.
Tightness as information
Persistent tightness in the same muscle is worth treating as information, not just something to rub out. Chronic tightness often signals a muscle that is overworked, frequently because it is compensating for a weaker or underused muscle elsewhere in the chain, so the durable fix is more likely to be strengthening the weak link than repeatedly massaging the symptom. This reasoning is clinical rather than strongly trial-backed, and “tight means weak” is an oversimplification, but it sits well with the strong evidence that strength training prevents injury: if a spot keeps tightening up, the more useful question is what keeps overloading it. Massage relieves the feeling; strength work is the better candidate for removing the cause.
