MOORE, MARJORIE A. and ROBERT S. HUTTON. Electromyographic investigaton of muscle stretching techniques. Med.Sci. Sports Exercise.Vol.12, No.5, pp.322-329,1980.Myotacic reflexes can be enhanced following brief static contractions. Since static contractions are often used as precursors to muscle stretch, rationale underlying these techniques were questioned and re-examined through electromyography (EMG). Twenty-one female gymnasts performed three methods to produce hamstring stretch: static, contract-relax, and contract-relax with agonist (hip flexor) contraction. Hip joint angles and intra-individual electromyograms were statistically compared across stretch conditions. In 12 subjects, the CRAC method elicited significantly greater hamstring EMG activity (P
