Abstract

There is a worldwide increase in the incidence of obesity that is associated with significant increases in medical costs. In the United States alone, treatment of obesity related health problems accounts for up to 9% of the total annual cost of healthcare, an estimated $147 billion per year. The effects of obesity on skeletal muscle are correlated with insulin resistance (IR), diabetes and decreased of quality of life. Recent work has demonstrated that a high fat diet (HFD) decreases the ability of skeletal muscle to hypertrophy in a model of increased mechanical load. This negative effect on muscle growth is correlated with a decrease in activation of the Akt/mTOR signaling pathway and an increase in endoplasmic reticulum stress. (AU)
