Abstract

PETERSON, J. M., T. A. TRAPPE, E. MYLONA, F. WHITE, C. P. LAMBERT, W. J. EVANS, and F. X. PIZZA. Ibuprofen and Acetaminophen: Effect on Muscle Inflammation after Eccentric Exercise. Med. Sci. Sports Exerc., Vol. 35, No. 6, pp. 892–896, 2003. Purpose We examined the influence of ibuprofen and acetaminophen on muscle neutrophil and macrophage concentrations after novel eccentric contractions. Methods Twenty-four males (25 ± 3 yr) were divided into three groups that received the maximal over-the-counter dose of either ibuprofen (1200 mg·d−1), acetaminophen (4000 mg·d−1), or a placebo after eccentric contractions of the knee extensors. Biopsies from the vastus lateralis were taken before and 24 h after exercise. Inflammatory cells were quantified in muscle cross-sections using immunohistochemistry. Results Macrophage concentrations were elevated by 1.5- to 2.5-fold (P < 0.05) at 24 h postexercise relative to preexercise concentrations, whereas neutrophil concentrations were not significantly elevated. Muscle inflammatory cell concentrations were unaffected by treatment with ibuprofen or acetaminophen when compared with placebo. Conclusions Maximal over-the-counter doses of ibuprofen or acetaminophen, when administered therapeutically, do not affect muscle concentrations of neutrophils or macrophages 24 h after a novel bout of eccentric contractions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
