Comparative effect of six-weeks static stretch, PNF, Graston technique, muscle energy technique and foam roller on the flexibility of hamstring muscle youth football players
Comparative effect of static stretching, PNF, Graston technique, muscle energy technique and foam roller on the flexibility of hamstring muscle in young football players.
Design
The clinical trial has a control group, with parallel groups of static stretching, PNF, Graston technique, muscle energy technique and foam roller. The sample size includes 90 football players who will be placed in 6 groups randomly (using Excel software).
Settings and conduct
The pre-test and post-test will be done in Shahid Beheshti University Sports Science Laboratory and the intervention will be done on the lawn on Khordad 15.
Participants/Inclusion and exclusion criteria
The age range of 12 to 15 years, Having a history of participating in football for 2 years, at least 3 training sessions per week and no history of hamstring and knee joint injuries. Exclusion criteria: Dissatisfaction with continuing cooperation in the research, having any neurological or orthopedic disease that affects the lower limbs.
Intervention groups
Static stretching, PNF stretching, Graston technique, muscle energy technique and foam roller are each performed for six weeks, 3 sessions per week. Control group: they continue their normal activities without intervention
Main outcome variables
Hamstring flexibility, active knee extension test

Description
Intervention group: Static stretch, Eight weeks, three sessions a week, Each of the participants to perform static stretching, first by keeping the spine in a neutral position, we ask the person to bend forward from the hip joint, and each subject is instructed to avoid bending the neck and only from the hip joint. move the hips, as a result of which the spine is kept in a neutral position. Subjects will actively flex the hip joint until the hamstring muscle is stretched with mild and tolerable pain, and will maintain this stretch for 30 seconds and repeat 4 times, resting 20 seconds between each repetition.

Description
Intervention group: PNF stretch, Eight weeks, three sessions a week, PNF Hold-Relax method will be used for PNF stretching. With subjects lying on their back while the opposite lower limb is fixed, the hamstring muscle tester performs passive hip abduction while the knee is fully extended. During the execution, it should be noted that the hip joint does not rotate, the subject's leg is placed on the examiner's shoulder, and the hamstring muscle is stretched until the subject first reports a slight stretching sensation, this position is maintained for 7 seconds, then the subject isometrically stretches the muscle Contracts the hamstrings by pressing the leg down against the tester's resistance for 3 seconds, after which the subject is asked to rest for 5 seconds, then the tester passively stretches the muscle until it feels a slight stretch. . This stretch will be performed for 7 seconds. This protocol will be repeated 4 times with an interval of 20 seconds

Description
Intervention group: Graston technique, Eight weeks, three sessions a week, Each participant in the GT group bends his knee 30 to 60 degrees with tool #1 after applying massage oil to the desired position, then the examiner will perform the movement from the posterior gluteal line to the popliteal cavity 30 times in 1 minute in 3 sets.

Description
Intervention group: muscle energy technique, Eight weeks, three sessions a week, Participants in the MET group will first lie on their backs and place their ankles on the examiner's shoulder. A MET cycle consists of 3 phases of rest, contraction (including a quadriceps muscle contraction at 15% of its maximal contraction force) and stretching, performed sequentially for 10 seconds each. This protocol is repeated 4 times with a 20 second rest between each repetition.

Description
Intervention group: Foam roller, Eight weeks, three sessions a week, Subjects sit on the floor of the foam roller and place their ischial ridge and leg stretched. Subjects are instructed to support their body weight with their hands placed on the floor. The exercise consisted of 3 repetitions of 1 minute with a 10-second rest between repetitions. The subject placed the legs together while using a foam roller while keeping the back of the thighs in a relaxed position.
