Several physically active individuals get muscle ache after workout, acknowledged as “delayed onset muscle soreness” or DOMS.
Foam rolling has emerged as a well known implies of alleviating delayed onset muscle mass soreness and rigid muscle mass.
You’re most likely to come across foam rollers in any fitness center, or you could have just one your self, and several men and women swear by using them just before and after exercise.
But what does the science say? Is foam rolling truly effective in decreasing delayed onset muscle soreness, and in expanding versatility?
Sadly, it is generally the case that scientific scientific tests do not necessarily help anecdotal evidence.
This looks to be the scenario with foam rolling. The proof doesn’t strongly aid the use of foam rollers – though some studies do present a tiny benefit.

What is foam rolling?
Foam rolling is a type of self-massage, usually employing a cylindrical foam roller.
They were first used in the 1980s, and are now commonly utilized in warm-up and/or great-down physical exercises.
Proponents say foam rolling can reduce muscle suffering, and improve versatility (also acknowledged as variety of motion).
But the mechanisms underlying these statements are not nicely acknowledged.

How does foam rolling function?
Foam rollers and other equivalent devices are claimed to launch the tightness of “myofascia”.
Myofascia is a slender connective tissue that surrounds our muscle tissues. It stops friction amongst tissues, and transfers power created by muscle fibres to the bone.
Myofascia can grow to be sticky and tight due to the fact of a sedentary way of living, repetitive movements that overworks 1 aspect of the human body, harm, or operation. Limited myofascia can lessen flexibility.
My analysis staff and I at Edith Cowan College investigated the purpose of myofascia in delayed onset muscle soreness.
Participants in our study did 10 sets of 6 bicep curls, and made really sore arms in the subsequent times.

We assessed their muscle mass soreness a single, two and 4 times following the training.
We also assessed their ache employing an “electrical stimulator” to quantify the sensitivity of the bicep fascia and muscle to electrical existing.
We uncovered the fascia encompassing the muscle mass turned much more delicate to electrical stimulation than the muscle by itself.
Scientists think little tears in muscle mass fibres are accountable for delayed onset muscle mass soreness. But our investigation implies injury to, or swelling of, myofascia is much more associated with delayed onset muscle mass soreness than damage to muscle mass fibres.
Foam rolling promises to extend the myofascia and thereby could lower these types of soreness and irritation.
But the evidence for foam rolling is combined
The evidence is still emerging, but there have been some studies into foam rolling.
A systematic review report of foam rolling centered on 49 scientific tests concluded foam rolling reduced muscle mass stiffness and pain, and greater vary of movement. But the authors stated it should be utilized in mix with dynamic stretching and an lively warm-up ahead of exercising.
An additional review examined whether or not foam rolling was efficient in minimizing delayed onset muscle soreness and maximizing muscle recovery. The members carried out two workout routines four months apart, each involving 10 sets of 10 back again squats.
1 team then foam rolled for 20 minutes immediately, 24 and 48 hrs just after work out, though one more group did no foam rolling at all. Foam rolling had a reasonable result on cutting down delayed onset muscle soreness.

But a different new review report with meta-investigation (which brings together the results of many scientific experiments) of 21 scientific studies on foam rolling concluded the effects of foam rolling on general performance and recovery were incredibly minimal, and foam rolling should be applied as a heat-up activity relatively than a restoration resource.
The short article also located foam rolling ahead of workout resulted in a compact enhancement in versatility by 4%. And rolling immediately after training lessened muscle mass soreness notion by 6%.
But statistical importance does not necessarily replicate functional importance. A 4% boost in overall flexibility and 6% reduction in suffering may perhaps not be noticed quite substantially by most men and women.
Also, several scientific tests identified foam rolling amplified vary of movement, but only for about 20 minutes.
So, the effects of foam rolling on overall flexibility do not show up to be large and the extensive-phrase outcomes are inconclusive.
A single problem with this spot of exploration is the rolling protocols utilised in the scientific studies were being various with no definitive settlement pertaining to the perfect amount of sets, duration, rolling frequency, or depth.
Interestingly, the magnitude of the impact on vary of movement following foam rolling is comparable to that of stretching.
So if your target is to raise variety of motion, both stretching and foam rolling can be thought of as adequate heat-up routines. No previous research have obviously confirmed foam rolling was a lot more successful than other interventions to increase overall flexibility ahead of workout.
But bear in mind: though foam rolling is generally regarded as safe and sound, it’s much better to keep away from it if you have a critical damage this kind of as a muscle tear, except your medical professional or a physical therapist has cleared you first.
