Effectiveness of Foam Rolling Against Changes in Range of Motion and Pain Degree due to Delayed Onset of Muscle Soreness Post 10Km Long Distance Running in Trained Young Men

Delayed Onset Muscle Soreness (DOMS) is a form of injury that often occurs after training. Once, muscle experiencing DOMS the body will experience decreased muscle strength, Range of Motion (ROM), increased inflammatory response. This is a Quasi Experiment, by using the One Group Repeated-Measures Design. Providing treatment with a foam roller to the sample to see changes in ROM body functions. The results of this study indicate that there is a decrease in ROM due to DOMS post a 10Km Long Distance Running activity. the calculated reduction in this research is lower extremities, namely Joint Hip, Knee, and Ankle. The research showed that there was a change in the Range of Motion after being measured at 24 hours, 48 hours and 72 hours compared to the pre-test data. The results of this study are based on statistical tests using Repeated Measures Anova with significant of P <.05. The result of pain degree is the distribution of muscle data that feels the greatest pain in Quadriceps Femoris 70%, Tibialis Anterior 30%, Triceps Surae 30%, Gluteus 30%, and Hamstring 10%. The conclusion of this study is the effect of foam roller on increasing Range of Motion and decreasing pain level that occurs in lower extremities.
