Detailed Description

High cholesterol and cardiovascular disease (CVD) is currently prevented and treated with statin therapy. Statin use can cause muscle weakness, fatigue and/or pain, and these symptoms can increase with dose and duration of statin use. Statins may also change the ability to exercise. This study is testing how different doses of a statin, Lipitor, affect muscle health and exercise. The doses that will be used in this study (20 mg/day or 80 mg/day) are typical for treating high cholesterol. This study is expected to last about 14 weeks.
