Comparison of Muscle Energy Technique and Eccentric Training on Hamstring Flexibility in Healthy Young Adults
Condition: Healthy
Study type: Interventional

Summary: 
      Flexibility is the ability of a muscle to lengthen and allow one joint (or more than one
      joint in series) to move through a full range of motion (ROM).Adequate flexibility is
      important to maintain balance, agility and musculoskeletal function. A decrease in muscular
      flexibility does not only reduces functional level of individual but also causes
      musculoskeletal injuries. Loss of muscle flexibility or muscle tightness is decreased ability
      of a muscle to lengthen which results in decreased ROM,and for hamstring reduced flexibility
      is the inability to achieve more than 160 degree of knee extension while the hip is flexed at
      90 degree.

      Muscle energy technique (MET) is an manual technique developed by osteopaths and is now used
      in many different manual therapy professions, to treat soft tissue, mobilize joints, stretch
      tight muscles and fascia, reduce pain and to improve circulation and lymphatic drainage.

      Eccentric training allows the muscle to elongate naturally, this elongation is achieved by
      having the subjects eccentrically contract the antagonist muscle to move the joint through
      the full available range in slow controlled manner.
    

Detailed description: 
      Flexibility is the ability of a muscle to lengthen and allow one joint (or more than one
      joint in series) to move through a full range of motion (ROM). Adequate flexibility is

      of a muscle to lengthen which results in decreased ROM. and for hamstring reduced flexibility
      is the inability to achieve more than 160 degree of knee extension while the hip is flexed at
      90 degree. Hamstring muscles have a great tendency to shortening even in normal
      circumstances, due to their multi-joint function and their tonic postural character.
      Techniques previously investigated for hamstring flexibility include static, ballistic and
      active assisted stretching exercise, ice, heat, soft tissue massage, ultra sound, Short Wave
      Diathermy, myofascial release, (PNF), kinesio taping, MET Each of these interventions has
      demonstrated clinical and experimental success; no agreement has been reached on a standard
      protocol for treatment.

      Muscle energy technique (MET) is an manual technique developed by osteopaths and is now used
      in many different manual therapy professions, to treat soft tissue, mobilize joints, stretch

      Eccentric training allows the muscle to elongate naturally, this elongation is achieved by
      having the subjects eccentrically contract the antagonist muscle to move the joint through
      the full available range in slow controlled manner. Eccentric resistance exercise may prevent
      injury to the muscle tendon unit by improving the muscle's ability to absorb more energy
      before failing and it is a better training strategy to improve the flexibility as it also
      increases strength and protects against muscle damage.
    

Intervention name(s): Eccentric Training; Muscle Energy Technique (PIR)
Intervention type(s): Other; Other
Intervention description(s): Once achieved, this flexed hip position will be held for 5 seconds. This procedure will be repeated 6 times with no rest between repetitions; The participant will be asked to resist the movement with no more than 25% of strength. The contraction will be held for 7-10 seconds followed by complete relaxation of the limb.
On exhalation, the knee joint will be straightened (extended) towards its new barrier and through that barrier a stretch was applied and maintained for 30 seconds.3 repetitions of this process will be done
Allocation: Randomized
Intervention model: Parallel Assignment
Masking: None (Open Label)
Primary purpose: Treatment
