Everyone’s felt it – the stiff, painful condition that results in your muscles the day after a tough workout. It makes you waddle up the stairs, sit gingerly on the toilet, or cry if someone pokes you in the chest. Within the fitness and performance training world, this pain is referred to as the DOMS, or “Delayed Onset Muscle Soreness”. As the name suggests, soreness is typically felt most between 24 and 48 hours after the training session has been completed.The DOMS – What is muscle soreness?Where does this pain come from? So often, we hear people exclaim that Lactic Acid is to blame. This really couldn’t be further from the truth. Lactate, a byproduct of one of the metabolic energy pathways, is actually a positive mechanism, one that serves as a control against your muscles becoming too acidic during intense exercise – the burning sensation you sometimes feel during high intensity work.In fact, post workout soreness is actually a result of microtrauma (aka small tears) within the muscle fibers and surrounding tissue. When you engage in physical training, you place stress upon the muscles (especially during the eccentric phase of any movement). If muscles are challenged to operate outside of their existing capacity, it will result in damage to the cells. This sounds negative, but it’s the trigger for adaptation within your body. When your muscles are being repaired after a workout, they are made bigger and stronger as a response. Your body works to prepare itself for the demands you place on it. This is the principle that directs all athletic training – your body will get better at whatever you consistently ask it to do.Treatment & PreventionWe should be entirely clear – there is no proven way to cure or prevent the DOMS. That being said, in our own personal experience, there are a number of ways to alleviate muscle soreness and help keep it from happening too frequently or severely during a training regimen.Ice and IbuprofenInflammation is the root cause of your pain. Dealing directly with the symptoms by icing and or using NSAIDs can certainly help. Do please keep appropriate pain-reliever use in mind!MassageMassage & self myofascial release (foam rolling/self-massage) has been known to help treat muscle soreness. It increases blood flow to damaged areas, delivering nutrients, clearing waste, and speeding up recovery.Contrasting TempsGoing back and forth from hot to cold (showers, sauna & pool, etc), shrinks and expands muscle fibers, forcing a flushing of blood through affected areas.

Sleep is the time your body runs internal diagnostics, rebuilds damaged structures, and prepares you for further action.Proper Post-Workout NutritionOften overlooked, the nutrients you feed your body after a bout of training is essential to your ability to recover quickly and perform at intensity again the next day. (Read our take here)Post-Workout Cool DownOur biggest recommendation for spurring recovery and preventing excessive soreness is a deliberate cool-down period after training. Light cardio, mixed with mobility work and static stretching can help both in the short term and long term.The best way to combat muscle soreness? More exercise. With gradual and deliberate warm up, another bout of training can help flush the muscles and speed up recovery. Just be sure not to jump in too hard or too fast. Listen to your body, it will tell you how things are going and how to proceed.When is it bad?Despite how it feels, the DOMS aren’t inherently a bad thing. For the most part, it is physical confirmation of hard work and progress. On the other hand, though, it doesn’t mean that only workouts that result in soreness are good workouts. More importantly, there is a point where soreness becomes the enemy. If you are reaching the point of pure pain as opposed to discomfort, pain lasts longer than a few days, or serious symptoms such as heavy swelling and darkened, discolored urine appear, you should consult a doctor immediately! These can be signs of a rare, and much more serious condition called rhabdomyolysis.Bottom line – you should neither love nor hate the DOMS. They are an inevitable part of the training process, but they are certainly not the only gauge of progress. In the end, you’ll see far better results if you allow your body to recover fully between efforts. The goal is consistency and continual work!
