Foam Rolling for Swimmers

Research investigating foam rollers, roller massagers, and other similar devices have generally reported increased range of motion (ROM), diminished perceived pain, accelerated recovery from exercise-induced muscle damage and augmented performance. This makes foam rolling for swimmers a pertinent topic for all swimmers and coaches.

The mechanisms underpinning these significant ROM increases with rolling may be quite diverse. Muscle, fascia, and skin are densely innervated by sensory neurons. A variety of receptors respond slowly (Merkel: small receptor field and Ruffini: large receptor field) or rapidly (Meissner small receptor field and Pacinian: large receptor field) to pressure and force. Although their primary responsibilities are for proprioception, Ruffini and Pacinian receptors contribute to sympathetic activity inhibition (contribute to muscle relaxation). Ruffini receptors are more sensitive to tangential forces and lateral stretch, which would be characteristics associated with rolling. In addition, interstitial type III and IV are multi-modal receptors (i.e., pain and mechanoreceptors) that can affect sympathetic and parasympathetic activation decreasing heart rate, blood pressure, ventilation, and promoting vasodilation. Thus, they can also contribute to a more relaxed muscle with less resistance to movement.

Reduced muscle reflex activity can also contribute to a more relaxed muscle. Manual massage and roller massage have attenuated the Hoffman (H)-reflex by 40–90%. A decreased H-reflex may be attributed to decreased afferent excitability of the alpha motoneuron or increased presynaptic inhibition, inhibiting the reflex-induced activation of the rolled muscle.

Furthermore, a similar mechanism for stretch-induced increases in ROM as proposed by Magnusson may be a rolling-induced increase in stretch tolerance. The experience of pain or discomfort with either stretching or rolling can be diminished with prolonged exposure allowing the individual to move beyond the prior limit of discomfort to achieve a greater ROM. Pain perception associated with delayed onset muscle soreness, myofascial tender spots, and evoked stimulation have all been reduced with rolling. Pablos and colleagues reported an increase in anti-inflammatory proteins and a reduction of pro-inflammatory proteins, when foam rolling after muscle damage in mice, which resulted in improved muscle recovery and performance. Massage can also stimulate parasympathetic activation; with changes in serotonin, cortisol, endorphin, and oxytocin contributing to a decreased pain perception contributing to an increased ROM tolerance.

Thixotropic effects could also contribute to rolling-induced increases in ROM. The direct and undulating pressures of rolling can decrease the tissue fluid viscosity providing less resistance to movement.

In summary, an array of mechanisms (i.e., increased stretch tolerance, decreased viscosity, fascial reflexes reducing sympathetic activation, attenuated muscle (H-) reflexes) may contribute to the acute rolling-induced increase in ROM.

The objective of this clinical commentary (Behm 2020) review was to appraise the rolling (foam rollers and roller massagers) literature to evaluate and recommend the exercise prescriptions that would provide large magnitude effect size improvements (i.e., volume [number of sets], repetition duration, rolling velocity/frequency, and intensity) for ROM and performance.

A total of 73 articles and 254 measures were used in the analysis.

Effect of Number of Sets on Range of Motion

When rolling, there were diminishing to trivial magnitudes of change with 5 (d = 0.056) or greater number of repetitions.

Effect of Rolling Set Duration on Range of Motion

It was predicted large magnitude effect size with 30-second (d = 1.01), 60-second (d = 1.12), 90-second (d = 1.18), and 120-second (d = 1.19) rolling set durations with a small effect size with 300-second (d = 0.29) set duration.

Effect of Rolling Frequency (Speed) on Range of Motion

It was predicted large magnitude effect size for increased ROM with 2-second (d = 1.66), 3-second (d = 1.85), and 4-second (d = 1.00) rolls (duration of a single roll in one direction over the length of a body part), with small (0.417) magnitude ROM improvements with 1-second rolling frequency respectively.

Effect of Rolling Intensity on Range of Motion

The one way ANOVA indicated there was no significant difference between rolling intensities.

Effect of Number of Sets on Strength and Jump Measures

With 36 total (11 positive and 25 negative) findings for strength measures and 32 total (16 positive and 16 negative) findings for jump measures, there were no significant difference between sets of rolling for strength or jump performance. The mean overall effect size for strength and jump measures were a trivial magnitude −0.19 ± 0.36 and −0.13 ± 0.43 respectively.

Effect of Rolling Set Duration on Strength and Jump Measures

There was no significant difference between rolling set durations for strength performance. All rolling durations (5, 10, 20, 30, 60-second) exhibited negative trivial to small magnitude effect size.

There was no significant (p = 0.8) difference between the trivial magnitude effect size with 30-second (d = −0.15 ± 0.09) and 60-second (d = −0.17 ± 0.11) rolling durations. A study by Drinkwater et al. used a rolling duration of 3 minutes with a small magnitude effect size impairment of −0.35.

Effect of Rolling Frequency on Strength and Jump Measures

Nine jump measures used a 1-second rolling frequency, whereas 5 measures used 2-second, one measure used 3-second, 3 measures used 4-second, and 2 measures used 6-second rolls, with all trivial magnitude effect size.

Effect of Rolling Intensity of Strength and Jump Measures

With jump measures, only 2 intensities were reported with 70% (2 measures) and 100% (14 measures) of maximum discomfort or pressure displaying nonsignificantly different (p = 0.3) mean small and trivial magnitude ES of −0.37 ± 0.75 and −0.06 ± 0.24 respectively. There were no significant (p = 0.8) regression coefficients relating rolling intensity and effect size for jump height performance.

Fatigue Endurance and Sprint

There were only 2 studies that investigated sprint changes with rolling with reported improvements of 1.2% (d: 0.85) and 6.2% (d: 0.24). There were insufficient number of studies to calculate regression equations.


The most important findings in this review were that to achieve the greatest ROM, the rolling prescription should involve 1–3 sets of 2–4-second repetition duration (time for a single roll in one direction over the length of a body part) with a total rolling duration of 30–120-second per set. Second, there were no significant findings for strength and jump measures with generally trivial-to-small magnitude rolling-induced performance deficits.

  1. Sorry! One of the worst hand positions one can use is pointing the fingers to the back or sideways. … even when just sitting on the floor… common error… it reinforces the bad habit of having hands facing backward with locked elbows … when slipping or falling, the reaction is to reach backward, resulting in broken arm(s)elbow(s), or wrist(s). Hands/fingers should always point forward the feet!! I recommend pointing this out to your readers because the hand positioning by athlete is reinforcing faulty mechanics, which coaches may imulate! This is one of the first safety principles we teach in Recreational Gymnastics in Canadian Coach Development course! Monika Schloder, PhD, Canadian Coach Developer.
