PNF Stretching Compared to SMR on Hamstrings

Not Applicable

• Conditions: Sports Physical Therapy
• Interventions: Other: PNF; Other: SMR

• Registration Number: NCT05134883
• Lead Sponsor: Universitat Internacional de Catalunya

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Propioceptive neuromuscular facilitation (PNF)	PNF	This group will undergo a PNF stretching on the hamstring muscles.
self myo-fascial release (SMR)	SMR	This group will undergo a SMR stretching on the hamstring muscles.

Primary Outcome Measures

Name	Time	Method
Hamstring muscle flexibility (mm)	Change between baseline(immediately before intervention), mid-intervention (30 seconds after the start of the intervention) and post intervention (2 minutes after the start of the intervention)	Evaluated with a modified sit-and-reach test (MSR). The participants sit on the floor with their lower limbs stretched out and together, their backs and hips are supported against the wall (90° hip flexion), and the soles of their feet are placed against the edge of a box. Participants then extended their arms forward, placing the same hand on top of the other with both hands facing down. During this, they keep their backs against the wall. They then reach forward, sliding their hands along the measuring scale as far as possible without bending their knees

Secondary Outcome Measures

Name	Time	Method
Discomfort sensation	Change between baseline(immediately before intervention), mid-intervention (30 seconds after start of intervention) and post intervention (2 minutes after the start of the intervention)	Measured using the Borg rating of perceived exertion scale (RPE). The participants will be asked at the end of the intervention to give a number from 1 to 10, where 1 is the easiest and 10 the hardest.
