People often take over-the-counter anti-inflammatory drugs like ibuprofen to ease the sting of delayed-onset muscle soreness (DOMS). Alas, research suggests taking these medications may blunt the training benefits of an exercise bout
researchers trying to determine the effects of high doses of anti-inflammatories on resistance training adaptations launched a study of 31 men and women (aged 18–35); 15 received a high dose (1,200 milligrams) of ibuprofen, while 16 received a negligible dose (75 mg) of aspirin. Each group performed 8 weeks of weight-stack resistance training and resistive flywheel (cycle) exercise (matched for training volume). After the 8 weeks, the aspirin group had double the increase in percentage of muscle volume gained and greater strength compared with the ibuprofen group.
These results suggest that taking maximal over-the-counter doses of anti-inflammatory drugs can thwart exercise gains in young adults. More research needs to be done to determine if lower doses of anti-inflammatory drugs have a similar detrimental effect.(See Resist Using Ibuprofen Right After Resistance Training for a related study.)
