Effect Stretching and Recovery on Delayed Onset Muscle Soreness (DOMS) After Exercise

Abstract

Abstract DOMS (Delayed Onset Muscle Soreness) is pain that a person feels within 24-72 hours after doing sports activities, and recovery occurs within 4-6 days. Pain is caused by metabolic waste such as lactic acid in muscles and extracellular fluids, irritating the ends of the sensory fibers. An exercise that is not adequately controlled can cause muscle damage, inflammation, and muscle pain. Recovery should be made after each exercise that aims to eliminate lactic acid in muscles. The study aimed to see the effect of stretching and recovery on DOMS after physical activity. This research method is a quasi-experimental research design using a randomized pre and post-test group design. The subjects in this study were students of the Department of Sport Science, Medan State University, who assessed 16 people. The research subjects were randomly divided into two groups. Group P1, namely the physical exercise group without stretching and recovery; Group P2 in the physical exercise group with stretching and recovery. This research will be conducted at the Physiology Laboratory and Physiology Laboratory, Faculty of Sport Sciences, State University of Medan. The results showed that there was an effect of stretching and recovery on the reduction of DOMS after physical exercise.
