Abstract
The age-related decline in muscle function is aggravated by a high-fat diet (HFD)-induced increase in fat mass. The hypothesis is that an HFD leads to a faster accumulation of intramyocellular lipids (IMCL) and an earlier onset of muscle dysfunction in old than in young-adult individuals. The IMCL accumulation is attenuated in young-adult organisms by an elevated oxidative capacity. Methionine restriction enhances mitochondrial biogenesis and is promising to combat obesity across the ages.
期刊介绍：
Exercise and Sport Sciences Reviews made the transition from an annual hardcover series book to a quarterly journal in January 2000. The mission of this American College of Sports Medicine publication is to provide premier quarterly reviews of the most contemporary scientific, medical, and research-based topics emerging in the field of sports medicine and exercise science. The publication strives to provide the most relevant, topical information to students, professors, clinicians, scientists, and professionals for practical and research applications.
