The purpose of this study was to investigate the effects of high-force eccentric muscle contractions on collagen remodeling and on circulating levels of matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMP) in humans. Nine volunteers [5 men and 4 women, mean age 23 (SD 4) yr] each performed a bout of 100 maximum voluntary eccentric contractions of the knee extensors. Muscle biopsies were taken before exercise and on days 4 and 22 afterward. Image analysis of stained tissue sections was used to quantify endomysial collagen staining intensity. Maximum voluntary contractile isometric force was recorded preexercise and on days 1, 2, 3, 4, 8, 11, and 14 postexercise. Venipuncture blood samples were also drawn on these days for measurement of serum creatine kinase activity and concentrations of MMP-9, TIMP-1, TIMP-2, and the MMP-2/TIMP-2 complex. Maximum voluntary contractile force declined by 39 ± 23% (mean ± SD) on day 2 postexercise and recovered thereafter. Serum creatine kinase activity peaked on day 4 postexercise ( P < 0.01). Collagen type IV staining intensity increased significantly on day 22 postexercise to 126 ± 29% (mean ± SD) of preexercise values ( P < 0.05). Serum MMP-9 levels increased on day 8 postexercise ( P < 0.01), and serum TIMP-1 was also significantly elevated on days 1, 2, 3, 4, and 14 postexercise ( P < 0.05). These results suggest that a single bout of eccentric muscle contractions results in remodeling of endomysial type IV collagen, possibly via the MMP pathway.

Nadh Fluorescence

Abstract A "reagentless" fluorometric method is described for the analysis of serum creatine kinase (CK) activity. The method is based on the use of silicone rubber pads, upon which are placed all the reagents for assay of CK. The rate of formation of NADH fluorescence at 460 nm is measured and equated to CK activity. The method is simple, rapid, inexpensive, and as little as 3 µl of serum is needed.

Atp Production

Abstract Adenylate kinase (EC 2.7.4.3) interferes positively in the serum creatine kinase (EC 2.7.3.2) assay when the rate of ATP production is monitored by a coupled enzyme system. A dual assay, measuring creatine kinase and adenylate kinase activity, was used to evaluate AMP and other possible adenylate kinase inhibitors that would permit specific measurement of creatine kinase activity in the presence of adenylate kinase. We found that AMP, routinely included in the creatine kinase assay system to inhibit adenylate kinase, partially inhibits both human serum creatine kinase and purified creatine kinase from rabbit muscle. The amount of creatine kinase inhibition is related directly to the AMP concentration and inversely to the substrate (ADP) concentration. We found that 25 mmol/liter of fluoride inhibits adenylate kinase without measurable effect on creatine kinase activity. We developed a serum creatine kinase assay including fluoride, and compared it with the dual assay system and with two commercial assay kits. Other halides or adenosine 2'-monophosphate did not selectively inhibit adenylate kinase.
