Changes

The most common NSAIDs (Ibuprofen, Acetaminophen (/Paracetamol), and Aspirin) are unlikely to help with DOMS, but Naproxen may reduce the pain and weakness. If an NSAID is taken, it should probably be immediately after the damaging exercise rather than waiting until the soreness develops. It seems likely that taking an NSAID for DOMS will reduce the muscular growth that would normally occur as part of the recovery. In one disturbing study, rabbits treated with an NSAID (flurbiprofen) after DOMS inducing exercise initially recovered their strength after 3-7 days, but between days 7 and 28 days the rabbits became weaker while the untreated controls became stronger<ref name="Mishra-1995"/>. I have not included other animal studies, but this is the only one that looks at how NSAIDs impact the longer term recovery from DOMS. Studies of Turmeric, which acts as a selective COX-2 NSAID<ref name="RamsewakDeWitt2000"/>, are promising. Reduction in soreness is mixed, with some studies showing reduced soreness<ref name="Nicol-2015"/><ref name="Drobnic-2014"/>, while others do not<ref name="McFarlinVenable2016"/><ref name="TanabeMaeda2015"/>. However, one study shoes reduced weakness and inflammation markers<ref name="TanabeMaeda2015"/> and an animal study showed less subsequent reduction in running performance in mice<ref name="Davis-2007"/>. Several studies showed reduced markers of damage<ref name="Kawanishi-2013"/><ref name="Davis-2007"/><ref name="TanabeMaeda2015"/><ref name="McFarlinVenable2016"/>. However, Turmeric should be treated like any other medication as there are safety concerns; see [[NSAIDs_and_Running#Turmeric_as_an_NSAID| Turmeric as an NSAID]] for details.
