Effects of Foam Rolling Prior to PNF Stretching on Hamstring Flexibility and Thigh Skin Temperature in Healthy Subjects (PNF)

Effects of Foam Roller Application Prior to Proprioceptive Neuromuscular Facilitation Stretching on Hamstring Flexibility and Thigh Skin Temperature in Healthy Subjects

There is no study investigating the hamstring flexibility and skin temperature after combined warm-up techniques especially PNF and foam rolling. The main purpose of this study is to investigate the effects of foam roller application prior to proprioceptive neuromuscular facilitation stretching on hamstring flexibility and thigh skin temperature in healthy subjects.Secondly, it is aimed to compare the effects between non-vibration foam rolling and vibration foam rolling on measured parameters.

Study Overview

• Status: Recruiting
• Conditions: Healthy
• Intervention / Treatment: Other: PNF stretching; Other: Non-vibration foam rolling prior to PNF stretching; Other: Vibration foam rolling prior to PNF stretching

Detailed Description

In this study forty-eight subjects will be voluntarily recruited into the study according to inclusion criteria. Participants will be randomly assigned to Vibration Foam Rolling + PNF stretching, Non-Vibration Foam Rolling + PNF stretching, only PNF stretching and control group. Subjects will be evaluated before, immediately after and 30 minutes after intervention. Hamstring flexibility will be evaluated with Active Knee Extension Angle (AKEA) Test and functionally Sit and Reach test. Thigh skin temperature will be evaluated with thermographic imaging.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in hamstring flexibility	Active Knee Extension test in supine position will be performed to measure hamstring flexibility.	Change from baseline hamstring flexibility at immediately after intervention and 30 minutes after intervention
Change in thigh skin temperature	Posterior thigh skin temperature will be evaluated using thermographic imaging with infrared thermal camera.	Change from baseline skin temperature at immediately after intervention and 30 minutes after intervention
Change in functional hamstring flexibility	Sit-and-Reach test will be performed to measure functional hamstring flexibility.	Change from baseline functional hamstring flexibility at immediately after intervention and 30 minutes after intervention
