Abstract
Foam rolling is a type of self-myofascial release that can
dramatically increase range of motion by reestablishing proper blood flow and
function. Myofascial releases are a way to break up adhesions and scar tissue,
decrease trigger points, and lengthen muscles. This experiment tested six
healthy, active individuals not currently participating in a varsity sport. The
researchers expected to find an increase in flexibility after foam rolling.
Each individual was tested using the Thomas test and had the degrees of hip and
knee flexion measured using a goniometer as well as a sit and reach test
measuring hamstring flexibility. The subjects then used a 6-inch high-density
plain foam roller for 30 seconds per muscle (including the piriformis,
hamstrings, quadriceps and illiotibial band). The subjects were then
immediately retested. The data supported
the hypothesis that flexibility would increase with foam rolling. Subjects
increased in the sit and reach test by an average of 1.85 inches. The average
knee flexion increased by 1.08 degree and the average hip flexion increased by
2.41 degrees. These findings are significant for all individuals with muscle
soreness and individuals with poor flexibility. Only 30 seconds of foam rolling
may improve scores by a significant amount and lead to decreased pain, risk of
injury, and increased muscle flexibility and function.
