Background: Delayed onset muscle soreness (DOMS) is an exercise-induced muscle soreness resulting from high-intensity eccentric muscular contractions. DOMS appears to be more prevalent in athletes at the beginning of an athletic season or when new movements or exercise are first introduced. The acute effect of DOMS on jumping mechanics is currently unknown. PURPOSE: The purpose of this study is to determine the effect of delayed onset muscle soreness on vertical jump performance and jumping mechanics. METHODS: Twenty college aged, recreationally active males participated in this study (age: 21.54 ± 2.61; height: 1.82 ± 0.067; mass: 81.36 ± 9.53). Participants were randomly assigned to the experimental (EXP) and control (CON) groups. Ground reaction forces (1000Hz) and motion capture (200Hz) were recorded for each of the 5 submaximal jump trials both PRE and POST Intervention. The intervention included two 15 minute runs with a 5 minute rest between. Participants in the CON group ran at a 0% grade while the EXP ran at a 10% decline. Participants then completed 4x10 of weighted box drop landing (EXP) or weighted box jumps (CON) with weight equal to 20% of their total body weight. Variables of interest during the landing portion of the jump can be found in the table below. A one-way ANOVA was conducted to compare percent change (POST-PRE) for each variable were compared across groups. RESULTS: Results of the study show that the EXP group experienced significantly greater soreness following their exercise protocol. All other variables of interest saw no statistically significant changes between PRE and POST exercise protocols. CONCLUSION: Data from this study suggests that the EXP group experienced significantly greater soreness following their exercise protocol. However, no changes to the landing mechanics during the vertical jump appear to be associated with the increased muscle soreness.
