Impact Of Non Steroidal Anti-Inflammatory Drug Administration Pre- Or Post-Resistance Training On Bone, David A. Cunningham, Kaleigh Camp, Evelyn Yuen, Stuart Solomon, Harry Hogan, Susan Bloomfield

International Journal of Exercise Science: Conference Proceedings

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) have been shown to suppress bone formation when administered before, but not if administered after, an acute bout of mechanical load. The effects of giving NSAIDs pre- and post-resistance training over multiple training sessions are not yet well defined. Therefore, the aim of this study was to elucidate the effects of NSAIDs when administered pre and post simulated resistance training (SRT) in a small animal model. We hypothesize that gains in bone mass and increased bone size will be diminished in adult rats given ibuprofen before each training session, but will be enhanced if ibuprofen is …
