Comparison of Muscle Energy Technique and Eccentric Training on Hamstring Flexibility in Healthy Young Adults

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.
