Figure 3. In vitro muscle function following 14 months of dietary quercetin enrichment .

A, the average of the specific tension measured in diaphragm strips used for measurement of resistance to fatigue or contraction‐induced injury was calculated and found to be similar in mdx and mdxQ groups and both were significantly less than C57. B, dietary quercetin enrichment did not improve resistance to contraction‐induced injury during five eccentric contractions. Force produced during contractions 2–5 (Con 2–5) was normalized to maximal force produced during the first contraction. ^*Significantly different from C57; ^#significantly different from mdx. C57 (n = 7), mdx (n = 6), mdxQ (n = 3).
