Yes, for a few things and only a little. A meta-analysis of 21 studies found that foam rolling before exercise gave a small, short-term gain in flexibility, and rolling after hard exercise slightly lowered soreness, with no meaningful change in strength or jumping1. Later reviews found the flexibility gain was no larger than stretching or other warm-up activity25.
What was studied
Foam rolling means rolling a muscle over a firm foam cylinder, pressing into it with body weight, a kind of self-massage. Roller sticks pressed by hand count too1. Range of motion means how far a joint can move, which is what "flexibility" measures in these studies.
The main paper pooled 21 controlled studies with 454 healthy, physically active people, from untrained to elite1. Fourteen studies (306 people) rolled before exercise as a warm-up. Seven (148 people) rolled after a hard bout to see whether it sped up recovery1. We read it in full.
Results are given as an effect size (Hedges' g): the difference between rolling and not rolling, divided by how much people normally differ. Under 0.2 is negligible, 0.2 small, 0.5 moderate and 0.8 large1.
| What | Number |
|---|---|
| Studies | 21 (searched up to December 2017) |
| People | 454 healthy, active |
| Rolled before exercise | 14 studies, 306 people |
| Rolled after exercise | 7 studies, 148 people |
| Devices | 14 foam rollers, 7 roller sticks |
In plain terms: a few hundred active people, short-term effects, measured on the day or the days after.
What the studies found
Before exercise: a little looser, not stronger. Rolling before exercise gave a small gain in flexibility (g = 0.34, about +4.0%) and in sprint times (g = 0.28, +0.7%)1. Strength (g = 0.12) and jumping (g = 0.09) did not change meaningfully1. Rolling beforehand did not make performance worse.

The sprint result needs care. A 0.7% change is below what a recreational athlete would notice, and it rests on only four studies1.
After exercise: slightly less sore. Rolling after a hard session lowered how sore people rated their muscles (g = 0.47, about 6%), the largest effect in the review, and still "small"1. Sprint recovery (g = 0.34) and strength recovery (g = 0.21) looked slightly better, but neither was statistically significant (p = 0.12 and p = 0.28)1. Jumping did not change (g = 0.06).

The authors' own summary: the effects "are rather minor and partly negligible, but can be relevant in some cases," such as for flexibility or muscle pain sensation, and that the evidence supports rolling "as a warm-up activity rather than a recovery tool"1.
In plain terms: rolling makes you a bit looser before and a bit less sore after; it does not make you stronger.
Is rolling special, or is it just moving?
This is where newer reviews matter.
Compared with doing nothing, rolling clearly adds range of motion in the moment. A 2020 multilevel meta-analysis of 26 trials found a large short-term effect against no exercise (0.74, 95% confidence interval 0.42 to 1.01)2. A confidence interval is the range the true value most likely sits in.
Compared with stretching, it was no better. Rolling against stretching came out at −0.02 (−0.73 to 0.69): no clear difference, though the interval is wide2.
Compared with any other warm-up, it was no better either. A 2024 meta-analysis of 38 studies and 1,134 people compared stretching and foam rolling with other activities, such as active warm-ups. Range of motion did not differ (effect size 0.01), and neither did muscle stiffness (0.09)5. The authors concluded there is "no need to emphasize stretching or foam rolling" to gain range of motion before exercise5.
Foam rolling and range of motion, three comparisons · SMD
Over weeks, range of motion rose; performance did not. Regular rolling for several weeks increased range of motion in 11 studies of 290 people (0.823, 95% CI 0.325 to 1.322), and more so when programmes lasted over 4 weeks3. It worked for the hamstrings and quadriceps, but not for ankle range when the calves were rolled3. Across 8 studies of rolling programmes longer than two weeks, performance showed no significant change (−0.294)4.
In plain terms: the looseness is real but not unique to rolling; almost any warm-up gets you there.
What it does and does not mean
It does not "break up fascia" or "release knots." The review lists mechanical, nervous-system and circulation explanations, and says the mechanisms are not fully understood1.
It does not remove expectation. Nobody can be blinded to being rolled, so the review rated the risk of a placebo effect "comparatively high"1. A placebo effect means doing or feeling better because you expect to.
It does not [add muscle or strength](/articles/does-stretching-build-muscle/). No study here found a meaningful strength gain before exercise or over weeks14.
It is not harmful to performance before lifting. Rolling beforehand did not lower strength or jumping1. That sets it apart from long static stretches, which did lower strength in the lab (see should you stretch before lifting).
What this looks like in practice
The studies that found a flexibility gain used rolling right before testing, and the gain was matched by stretching or other warm-up activity25. The studies that found less soreness used rolling after a hard bout1. There is no agreed best dose of time, pressure or speed1. For getting ready to lift, what the evidence says about warm-ups is in does warming up help. What soreness does and does not tell you about a workout is covered in does soreness mean muscle growth.

Limits worth knowing
- No blinding. People always know they are being rolled1.
- Small studies, mixed methods. Devices, durations, muscles and pressure varied, and pressure was rarely measured.
- Short-term outcomes. Most results are from the same day or the next few days.
- Soreness is a rating. It is how sore people said they felt, not a measure of muscle repair.
- Abstracts only for every paper except the 2019 meta-analysis. For the 2024 soreness review we used only its conclusion and study count, because the abstract's list of effect sizes is hard to map to time points.
Latest research
The newest pooled evidence we opened is from 2024. One meta-analysis of 38 studies found that neither foam rolling nor stretching beat other warm-up activities for range of motion, stiffness or passive torque, with fair study quality5. Another, of 16 randomised trials and 515 people, found rolling after exercise lowered soreness, with a tiny effect straight away and a clearer one from 24 hours on6. Both fit the 2019 picture: small help with how you feel, no special effect on how you perform.
The short version
- Rolling before exercise gave a small, short-term flexibility gain and no meaningful change in strength or jumping.
- Rolling after hard exercise slightly lowered soreness ratings; sprint and strength recovery did not change significantly.
- The flexibility gain matched stretching and other warm-ups rather than beating them.
- Nobody can be blinded to rolling, so expectation may explain part of the effect.
