Hendricks S et al. · 2020Journal of Bodywork and Movement TherapiesSystematic review of **49** articles (seven databases, English-language, January 2006 – June 2019; PROSPERO CRD42017064976) asking whether foam rolling is better used as a warm-up to aid performance or as a cool-down to aid recovery. Any design was eligible provided one condition was foam rolling alone.
The authors' conclusions are favourable on both counts, not equivocal: "FR may reduce muscle stiffness and increase ROM and should be used in combination with dynamic stretching and active warm-up before a training session. Furthermore, the optimum dosage to achieve these flexibility benefits seems to be a total 90s-120s of FR. FR reduced DOMS and increased PPT, and therefore may optimize recovery from training."
Two things to hold against it. The included work is dominated by small, unblinded trials, and the authors' own recommendation for future research is that studies "should include true controls or sham groups" — an acknowledgement that the measured benefits (soreness, pressure pain threshold, range of motion) are all subjective or expectation-sensitive and have largely not been tested against a credible sham. And this is a narrative vote-count with no pooled effect size, so it establishes the direction of the literature rather than the size of any effect.

Beardsley C & Skarabot J · 2015Journal of Bodywork and Movement TherapiesSystematic review (PubMed and Google Scholar, searched February 2015) of the acute and chronic clinical effects of self-myofascial release (SMFR) — foam rolling and roller-massage. Its findings run the *other* way to a debunking: acutely, "SMFR seems to increase flexibility and reduce muscle soreness but does not impede athletic performance," and it may acutely improve arterial and vascular endothelial function and raise parasympathetic activity, which the authors suggest could be useful in recovery. The one negative note is long-term flexibility, where the authors report "conflicting evidence." The stated conclusion is favourable: "SMFR appears to have a range of potentially valuable effects for both athletes and the general population, including increasing flexibility and enhancing recovery."
On mechanism, the authors do not adjudicate: they report that although SMFR appears to have acute and chronic effects, there is currently **no consensus regarding the exact mechanism or mechanisms** by which it produces them, and that many mechanisms have been suggested. This paper therefore cannot be cited for the claim that foam rolling's mechanical force is too small to deform fascia, nor for the claim that its effects are specifically neurophysiological — it takes no position on either.

Wiewelhove T et al. · 2019Frontiers in PhysiologyMeta-analysis of 21 studies (454 subjects; 14 studies of pre-rolling, 7 of post-rolling) covering foam rolling both as a warm-up and as a recovery strategy. Used **after** exercise, foam rolling reduced muscle pain perception (+6.0%, g = 0.47), slightly attenuated exercise-induced decreases in sprint (+3.1%, g = 0.34) and strength (+3.9%, g = 0.21), and had a trivial effect on jump performance (−0.2%, g = 0.06). Used **before** exercise it gave a small improvement in sprint (+0.7%, g = 0.28) and flexibility (+4.0%, g = 0.34), with negligible effects on jump and strength. Every effect is small. The authors' overall verdict is that "the effects of foam rolling on performance and recovery are rather minor and partly negligible" and that the evidence "seems to justify the widespread use of foam rolling as a warm-up activity rather than a recovery tool" — the reverse of how it is usually sold. The one outcome that moved most, muscle pain, is self-reported in an intervention that cannot be blinded, which is exactly where expectancy inflates results.

Effects are small throughout. Post-exercise (recovery) rolling reduced muscle pain perception (+6.0%, g = 0.47) and slightly attenuated losses in sprint (+3.1%, g = 0.34) and strength (+3.9%, g = 0.21); the jump effect was trivial (g = 0.06). Pre-exercise rolling improved sprint (g = 0.28) and flexibility (g = 0.34). The authors conclude the evidence justifies foam rolling as a warm-up activity rather than as a recovery tool

Weighted 0.65 — 21 studies but only 454 pooled subjects. The significant effects are on self-reported soreness in an intervention that cannot be blinded — exactly where expectancy inflates results — while the objective outcomes (strength, jump) came out null.

Foam rolling reduced DOMS and increased pressure pain threshold, so it may optimise recovery; it may also reduce muscle stiffness and increase range of motion pre-training, with an optimal dose of about 90-120 s total
Systematic review of 49 articles (seven databases, English-language, January 2006 – June 2019; PROSPERO CRD42017064976) asking whether foam rolling is better used as a warm-up to aid performance or as a cool-down to aid recovery. Any design was eligible provided one condition was foam rolling alone.
The authors' conclusions are favourable on both counts, not equivocal: "FR may reduce muscle stiffness and increase ROM and should be used in combination with dynamic stretching and active warm-up before a training session. Furthermore, the optimum dosage to achieve these flexibility benefits seems to be a total 90s-120s of FR. FR reduced DOMS and increased PPT, and therefore may optimize recovery from training."
Two things to hold against it. The included work is dominated by small, unblinded trials, and the authors' own recommendation for future research is that studies "should include true controls or sham groups" — an acknowledgement that the measured benefits (soreness, pressure pain threshold, range of motion) are all subjective or expectation-sensitive and have largely not been tested against a credible sham. And this is a narrative vote-count with no pooled effect size, so it establishes the direction of the literature rather than the size of any effect.
Weighted 0.50 — k=49 articles; no meta-analysis and no pooled participant count, so sample_size is omitted, and no funding statement was accessible. This is a vote-counting review of small, largely unblinded trials on outcomes (soreness, pressure pain threshold, range of motion) that are the most placebo-prone in the literature - the authors themselves call for future studies to include true control or sham groups. The DOI recorded here (10.26603/ijspt20200825) is wrong: the real paper is J Bodyw Mov Ther 2020;24(2):151-174, doi 10.1016/j.jbmt.2019.10.019. The journal field is correct. NOTE: this record previously described a 14-study review finding inconsistent performance-recovery effects and a possible placebo explanation. The review contains 49 articles and reaches a favourable conclusion on recovery; the abstract makes no claim about strength/power/speed recovery being inconsistent. The full text is paywalled, so the effect and body have been rewritten to the abstract's stated conclusions only.

Acutely, self-myofascial release increases flexibility and reduces muscle soreness without impairing athletic performance; evidence that it improves flexibility long-term is conflicting; the authors state there is no consensus on the mechanism
Systematic review (PubMed and Google Scholar, searched February 2015) of the acute and chronic clinical effects of self-myofascial release (SMFR) — foam rolling and roller-massage. Its findings run the other way to a debunking: acutely, "SMFR seems to increase flexibility and reduce muscle soreness but does not impede athletic performance," and it may acutely improve arterial and vascular endothelial function and raise parasympathetic activity, which the authors suggest could be useful in recovery. The one negative note is long-term flexibility, where the authors report "conflicting evidence." The stated conclusion is favourable: "SMFR appears to have a range of potentially valuable effects for both athletes and the general population, including increasing flexibility and enhancing recovery."
On mechanism, the authors do not adjudicate: they report that although SMFR appears to have acute and chronic effects, there is currently no consensus regarding the exact mechanism or mechanisms by which it produces them, and that many mechanisms have been suggested. This paper therefore cannot be cited for the claim that foam rolling's mechanical force is too small to deform fascia, nor for the claim that its effects are specifically neurophysiological — it takes no position on either.
Weighted 0.45 — No pooled data or meta-analysis, so sample_size is omitted; no funding statement could be verified, so that field is omitted too. The review is vote-counting rather than quantitative, its included trials are small and mostly unblinded, and the flexibility/soreness outcomes are the ones most vulnerable to placebo. The study_type recorded here (narrative_review) is wrong: the paper is titled and designed as a systematic review. NOTE: this record previously claimed the paper argues foam rolling cannot mechanically deform fascia and that its effects are neurophysiological. The paper makes no such argument in its abstract or conclusions — it explicitly reports "no consensus regarding the exact mechanism" — and its overall conclusion is favourable to SMFR. The full text is paywalled and could not be read, so the effect and body have been rewritten to the abstract's stated findings only.
