Soreness should be perceived as a signal that "some level of tissue injury is present," Braun said. iStock/Getty Images Plus Should You Workout When You're Sore? DOMS can take place after weight lifting workouts, which entails muscle lengthening moves. In fact, symptoms of severe DOMS have been shown to delay strength recovery for up to a month."ĭuring this period of time, it's likely that the quality of your training will be poorer, which could interfere with muscle growth, according to Braun.įranco agreed, noting that while exercise-induced muscle damage is a necessary part of hypertrophy, "DOMS may actually be counterproductive to muscle tissue growth and development."Ī man laying on a mat while holding side of arm muscle next to a large barbell weight. However, "DOMS is not likely to be absolutely necessary to promote muscle fiber enlargement. You don't have to sustain high levels of pain or damage to enable this process but it is more likely that a weight lifter will experience some level of soreness with intensified training, he said. Inflammatory markers, such as white blood cells, red blood cells, and cytokines, in addition to lactic acid, build up in the area to help with the remodeling process, the certified athletic trainer said.īraun noted there is evidence that muscle enlargement (muscle hypertrophy) is better supported when "eccentric loading is given attention during weightlifting training." The body adapts and rebuilds itself into a stronger form through the inflammatory process. In fact, in this instance it is a necessity to ensure proper recovery and remodeling of the muscle tissue," he explained. "Contrary to popular belief, inflammation is not always bad. Those "microtears" are caused by a stimulus (stress/load) placed on the muscle. iStock / Getty Images Plus Is DOMS a Sign of Muscle Growth?ĭOMS and other types of soreness are an indication of muscle growth, Martinez said. DOMS can take place within 24 to 72 hours following exercise. With the nature of DOMS pain usually peaking around 24 to 72 hours after a training session or after you perform a certain unaccustomed exercise, "it's pretty impractical to gauge the quality of a training session by how sore you became a few days later," he said.Ī woman sitting up on a yoga mat while massaging her upper leg muscle. In fact, if this were the case, you would have to wait around for a day or two to gauge whether pain shows up to decide if that was a good session or not, which would be kind of inconvenient." "Currently, the most accepted cause of DOMS is the combination of two factors-damage to the muscle and connective tissue caused by vigorous exercise, followed by the associated inflammatory response," he explained.īraun said: "You don't have to experience delayed soreness to achieve a good workout session. So lactic acid is less likely to be related to pain or discomfort during the 24 to 72 hour period following exercise. He noted that while lactic acid is most commonly blamed for DOMS, recent studies suggest that after a period of intense exercise, lactic acid levels return to normal within one hour. iStock/Getty Images Plus Is DOMS a Sign of a Good Gym Session?įranco said: "DOMS is one of the most common forms of sports or exercise-related injuries and not necessarily a sign of a good workout." Delayed onset muscle soreness can occur during certain muscle lengthening exercises, such as bicep curls.

Roger Franco, an assistant fitness manager at Crunch Fitness in Fort Greene in the New York City borough of Brooklyn, told Newsweek, several factors can contribute to pain associated with DOMS, such as the following: Braun explained: "Think of T-rex arms in a human-following very intensive eccentric loading of the elbow flexors, the elbow joint can temporarily lose full extension and potentially full flexion for several days."
