Strenuous exercise results in damage to skeletal muscle that is manifested in delayed muscle pain, prolonged strength loss, and increases in muscle proteins in the blood, especially creatine kinase (CK) and myoglobin (Mb). Some individuals experience profound changes in these variables in response to standard laboratory exercise or recreational activities.(More)
PURPOSE This study examined sex differences in strength loss, muscle soreness, and serum creatine kinase (CK) and myoglobin (Mb) after high-intensity eccentric exercise of the elbow flexors in a large group of men and women. METHODS One hundred participants (58 women, 42 men) performed 50 maximal eccentric contractions of the elbow flexor muscles of their(More)
Novel eccentric (lengthening contraction) exercise typically results in muscle damage, which manifests as prolonged muscle dysfunction, delayed onset muscle soreness, and leakage of muscle proteins into circulation. There is a large degree of variability in the damage response of individuals to eccentric exercise, with higher responders at risk for(More)
PURPOSE Serum creatine kinase (CK) levels are commonly used to judge the severity of muscle damage and to determine when to hospitalize patients who present with symptoms of exertional rhabdomyolysis in order to prevent renal failure. However, no CK standard exists because of the limited information available regarding exercise-induced CK elevation and(More)
We examined the association of a novel single-nucleotide polymorphism (SNP) in IGF-I (IGF-I -C1245T located in the promoter) and eight SNPs in the IGF-II gene region with indicators of muscle damage [strength loss, muscle soreness, and increases in circulating levels of creatine kinase (CK) and myoglobin] after eccentric exercise. We also examined two SNPs(More)
The aim of this study was to evaluate the efficacy of rosuvastatin twice weekly in 40 patients intolerant to daily statins. Rosuvastatin twice weekly alone or added to other lipid-lowering medications decreased total cholesterol by 19%, low-density lipoprotein cholesterol by 26%, and triglycerides by 14% (p<0.01 for all). High-density lipoprotein(More)
INTRODUCTION Hydroxy-methyl-glutaryl co-enzyme A (HMG-CoA) reductase inhibitors or statins are well tolerated by most patients, but can produce a variety of skeletal muscle problems including myalgia, creatine kinase (CK) elevations and clinically important rhabdomyolysis. We have previously demonstrated that the CK response to downhill walking is greater(More)
Genome-wide association studies have identified thousands of variants that are associated with numerous phenotypes. One such variant, rs13266634, a nonsynonymous single nucleotide polymorphism in the solute carrier family 30 (zinc transporter) member eight gene, is associated with a 53% increase in the risk of developing type 2 diabetes (T2D). We(More)
