Effect of iron supplementation on thyroid hormone levels and resting metabolic rate in two college female athletes: a case study.

abstract：BACKGROUND:Time spent in sedentary activities (such as watching television) has previously been associated with several risk factors for cardiovascular disease (CVD) such as increased low-density lipoprotein cholesterol (LDL-C). Little is known about associations with lipoprotein subfractions. Using television and comp...
