The effect of warm up on indices of delayed-onset muscle soreness after eccentric concentrations in non-athletes collegiate students

DOMS is one of the most common muscle injury during sports activities and even everyday life. In order to reduce the effects of DOMS provide prevention and treatment strategies are needed. The purpose of this study was to determine the effects of warm up on indices of male students DOMS after eccentric contractions. In this experimental study، 18 non-athlete students in Guilan University voluntarily participated in this study. The subjects were randomly divided into two groups: warm-up (5 minutes running with an intensity of 60 % maximum heart rate، 6 minutes of static stretching and 25 repetitions in 2 sets with 20% 1RM) and the control groups. The outcome measures were: serum CK، neutrophil counts، isometric maximal voluntary contraction force (MVC) and muscular pain perception. Quality parameters measured before، 24، 48 and 72 h after eccentric exercise. Repeated measures analysis of variance and ANOVA test was used to assess differences between the two groups. Serum creatine kinase، neutrophils and pain perception in both groups increased and decreased levels of (MVC). Significant differences between the two groups observed in the count of neutrophils at 48 hours after exercise. The findings of this study indicate that warm up cannot cause a significant decrease in DOMS.
