Abstract

One of the most frequent effects of aging is the involuntary loss of muscle mass, strength and function, termed sarcopenia. Longitudinal data suggest that muscle strength is a robust predictor of functional decline that occur during aging. Since strength capacity appears to also be indicative of disability, resistance training may serve as an effective mode of physical activity to directly improve functional capacity. There is also a growing evidence to indicate that age-related decline in production and activity of hormones plays an important role in aging muscle. Testosterone deficiency has been associated with a marked decrease in measures of whole body protein anabolism and decrease strength. The purpose of the present study was to explore the characteristics of the methodological approaches used in the studies related to the role of resistance training and androgenic anabolic steroids in the aged skeletal muscle that have been published in the last ten years. A literature review was conducted in April 2011 using the following databases: PubMed; Medline; Lilacs; and Scielo. We found sixty two articles analyzing the influence of resistance training on skeletal muscle of aged samples, seven articles which proposed to verify the chronic influence of androgenic anabolic steroids and only one article mixing both interventions. The great variety of analysis methods is notable. Morphological analysis was done in only few articles.
