Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The use of stretching techniques in the sports world is frequent and widely used for its many effects. One of the main benefits is the gain in flexibility, range of motion and facilitation of the sporting performance. Recently the use of self-myofascial release (SMR) has spread in sports practice both at elite and recreational level for its benefits being similar to those observed in stretching. The objective of the following study is to compare the results of the proprioceptive neuromuscular facilitation stretching with SMR on the hamstring muscle flexibility.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Propioceptive neuromuscular facilitation (PNF)

This group will undergo a PNF stretching on the hamstring muscles.

Group Type EXPERIMENTAL

PNF

Intervention Type OTHER

A PNF stretching protocol will be performed with each participant assuming a long sitting position on a plinth with the knee maintained as extended as possible. At this moment, the participant will be asked to perform a maximum isometric hamstring muscle contraction for 5 seconds followed by 5 seconds of relaxation and 20 seconds of stretching. The therapist will show the participant how to maintain this isometric contraction with the flexion of the hip and ankle. Each participant will undergo 4 repetitions of PNF stretching (30 seconds/rep).

self myo-fascial release (SMR)

This group will undergo a SMR stretching on the hamstring muscles.

Group Type ACTIVE_COMPARATOR

SMR

Intervention Type OTHER

For the application of self-myofascial release, the subjects will assume a long sitting position on a firm and even surface by placing the arms backward and transferring their body weight to their palms. The roller foam, applied bilaterally, will be placed under the hamstrings and slowly moved back and forth from the ischial tuberosity to the popliteal fossa by applying pressure for 2 minutes.
