The Acute Effects in Postural Sway as a Result of Self-Myofascial Release on the Lower Extremities

A study publishe din International Journal of Sports Science investigates the impact of myofascial release, specifically foam rolling, on postural control by comparing the effects of rolling on different muscle groups. The focus was on observing changes in postural sway scores before and after foam rolling the proximal muscles (quadriceps and hamstrings) versus the distal muscles (calves) in college-aged female athletes.

Thirty-six college-aged female athletes were divided into two groups, underwent two and a half minutes of moderate intensity foam rolling—Group A on their calves and Group B on their quadriceps and hamstrings. Postural control was assessed using a computerized posturography balance plate, measuring Center of Pressure (CoP) and Limits of Stability (LoS) under various conditions including eyes open or closed, and on stable or unstable surfaces.

The results indicated that while CoP did not significantly change pre- and post-foam rolling in either group, there was a notable difference in LoS. Specifically, LoS showed a frontal plane preference and exhibited a significant interaction effect between time, group, and direction—Group A showed a decrease in LoS post-foam rolling, whereas Group B saw an increase.

In conclusion, the study found differences in postural control improvements between the two groups following foam rolling, suggesting potential benefits in manipulating connective tissue for posture maintenance. Further investigation is needed to explore long-term effects and confirm these findings.
