MacDonald, et al (2013)say that fascial restriction is a common response to injury in which fascial tissue loses elasticity and becomes dehydrated. As a result, fascia can bind around traumatized areas and fibrous adhesions form which prevent normal muscle mechanism and joint range of movement (ROM). Barnes (1997)developed myofascial release (MFR) therapy to help reduce fibrous adhesions and in the last decade self-myofascial release (SMR) has become an increasingly popular technique for treating the soft tissue and preventing muscular dysfunctions (Healey, Hatfield, Blanpied, Dorfman, & Riebe, 2014). SMR works under the same principles as MRF, but it involves patients using their body weight with a myofascial foam roller to treat restrictions in the soft tissue. Foam rollers vary in length, diameter, density and surface texture for varying amounts of pressure in different areas of the body.
Healey, Hatfield, Blanpied, Dorfman, and Riebe(2014) say that regular over exercise or misuse can result in microtrauma which overtime may lead to fascia scar tissue. SMR can be used in a variety of body positions to isolate specific areas of the body or muscle groups to improve mobility. Foam rollers are commonly found in gyms as they can be used before and after a workout (Healey et al., 2014). A study by Griefahn, Oehlmann, Zalpour, and Von Piekartz (2017)found that foam roll exercises significantly improve the mobility of the thoracolumbar fascia (TLF) in the young, healthy population. The study divided 38 healthy active men and women into three conditions: exercises with the foam roller, placebo group and control group. They found that the use of a foam roller increased the mobility of the TLF by 1.7915mm compared to 0.1681mm with the placebo and 0.0139mm in the control group. This highlights the effectiveness of foam rollers and provides evidence for the use of foam rollers in increasing mobility of the fascia.
Foam rolling prior to a workout has been said to have a similar effect to massage in restoring muscle length-tension relationship (Boyle, 2009). Foam rollers allow for a better warm-up by allowing an athlete to increase their volume of training and decrease dysfunctions without the expense of hiring a sports therapist.
A drawback to the use of foam rollers is that there is limited empirical evidence into the different effects of SMR. Healey et al., (2014)state that: “To date, there is no research investigating whether SMR enhances performance through massage-like treatment to the soft tissue or if there is simply a warm-up effect to performing the isometric hold.” This implies that there is evidence that SMR does enhance performance, but further research is required to identify the mechanisms behind why the improvement occurs. In addition, the literature that does exist focuses on the chronic effects of SMR and not the acute, therefore the results of available research studies may not be applicable to all injuries.
A further limitation is that the prescription for foam rolling is subjective and there is a lot of variance between studies. It can be seen from a variety of studies, that the amount of time a patient is advised to use the foam roller varies from study to study. Research by Healey et al (2014)compared the effects of 30 seconds of foam rolling and planking and found no significant difference between the two methods other than participants showing fatigue post planking. This suggests that foam rolling for 30 seconds doesn’t improve performance but does cause less fatigue than planking. In contrast research by Murray, Jones, Horobeanu, Turner, and Sproule (2016)looked at the effects of 60 seconds of foam rolling and found it had no impact on the change in the participants quadriceps contractility and temperature. Furthermore, Couture, Karlik, Glass, and Hatzel (2015)examined the effect of varied durations of foam roller treatments on hamstring ROM and found that neither short duration (67.30 ± 10.60 deg) nor long duration (67.41 ± 10.81 deg) produced significant increases in knee extension compared to the baseline.
To conclude, foam rolling has the potential to be a useful treatment as a cheaper alternative to sports therapist massage pre and post workout, however more research is required to determine the optimum time prescriptions in order to gain the best individual effects from this equipment. In addition, further research may be useful in order to establish the physiology behind why foam rolling is or is not as effective as a massage.
