Acute Effects of Foam Rolling and Proprioceptive Neuromuscular Facilitation Stretching

Participants will take a long sitting position on a solid and flat surface, positioning their arms back and transferring their body weight to their palms. The foam roller to be applied to the dominant side will be placed under the hamstrings and slowly moved back and forth from the ischial tuberosity to the popliteal fossa, applying pressure for 2 minutes.

A PNF stretching protocol will be implemented with each participant assuming a tall sitting position on a solid, flat surface with their knees extended as much as possible. At this moment, the participant will be asked to perform maximum isometric hamstring muscle contraction for 5 seconds, followed by 5 seconds of relaxation and 20 seconds of stretching.
