The effect of passive stretching on delayed onset muscle soreness, and other detrimen-tal effects following eccentric exercise. Scand J Med Sci Sports 1998: 8: 216-221. 0 Munksgaard, 1998 The aim of this study was to measure if passive stretching would influence delayed onset muscle soreness (DOMS), dynamic muscle strength, plasma creatine kinase concentration (CK) and the ratio of phosphocreat-ine to inorganic phosphate (PCr/Pi) following eccentric exercise. Seven healthy untrained women, 2846 years old, performed eccentric exercise with the right m. quadriceps in an isokinetic dynamometer (Biodex, angle velocity: 60". s-') until exhaustion, in two different experiments, with an interval of 13-23 months. In both experiments the PCr/Pi ratio, dynami
