Pain killers and muscle growth
Long term use of anti inflammatory pain killers such as ibuprofen can inhibit muscle growth.
A recent study found that participants taking ibuprofen gained half as much muscle volume as measured by MRI compared to those taking aspirin after 8 weeks of resistance training 3x per week. Strength increases were also worse in the ibuprofen group.
Researchers also measured markers of inflammation which were reduced in the ibuprofen group and speculate that inflammation may be an important signal for muscle growth.
You may want to think twice before taking anti inflammatory pain killers if they are not essential and if your goal is to build muscle.
