Summary

To assess the immediate effects of hamstring stretching alone or combined with myofascial release of the hamstring muscle on masseter muscle activity, pressure pain threshold, active mouth opening, hamstring flexibility, and forward head flexed posture in recreationally active participants. The young, healthy, recreationally active adults aged 18-25 years were included in the study. The participants were randomly separated into two groups of equal number. Static stretching alone was applied to one group and this was combined with myofascial release techniques (SSMR) for the other group. Masseter muscle activity was assessed using a NORAXON® surface electromyography device. Both pre-and post-intervention, mechanical pressure algometer was used to measure the pressure pain threshold, hamstring flexibility was evaluated using the maximum hip flexion and active knee extension test, the maximum mouth opening (MMO) was measured with the millimetric ruler, and forward flexed posture was evaluated using the tragus to wall distance test.

Conditions

• Hamstring Injury
• Masseter
• Myofascial Release
• Stretching
• Surface EMG
• Temporomandibular Joint Disorders

Interventions

Type	Name	Description
PROCEDURE	Static stretching	The participant was positioned supine for static stretching to be applied to the hamstring muscles. The physiotherapist flexed the participant's hip to the point where resistance to the movement was first observed, with the knee extended.At this point, after waiting for 40 seconds, it was returned to the previous position. This application was made on both sides \[Bretischwerdt\]. The technique was repeated three times, with a 15-second rest interval between each repetition.
PROCEDURE	Myofascial Release	For hamstring muscles, the participants were asked to assume a long sitting position on a firm, flat surface with their arms behind their backs and their body weight on their palms. A foam roller was placed under the hamstring muscles and slowly moved the tuberositas ischii popliteus back and forth with pressure for 4 minutes.
