Hi:
You might want to tell him that Ibuprofen has been shown to stop protein synthesis - that's the process that's essential for muscle growth - so when he pops his ibupro, he's essentially wasted his whole workout!
Ibuprofen has been shown to stop protein synthesis
Really - wow would like to read that one.
I assume that ibuprofen reduces swelling and therefore could help after a workout?
Here's the reference:
Medicine and Science in Sports & Exercise, vol 35, no 6, pp892-896, 2003.
Their final conclusion was that NSAIDs are ineffective in treating muscle soreness and inflamation, and impair protein synthesis in humans after eccentric exercise.
