Sarcopenia and Protein Intake: Is the RDA Adequate?
Introduction
Sarcopenia is an age related condition which is characterized by a loss of skeletal muscle and function.1 The decline in skeletal muscle begins in the fourth decade of life and by age 80 a 30% reduction in muscle mass can be seen, with even greater losses in functional strength.1 Significant decrements in muscle mass and strength increase the risk of morbidity and mortality in the aged.1 The prevalence of sarcopenia in 60 year olds has been found to be almost 50% in men and 60% in women.2 Optimal protein intake in the elderly has been shown to reduce the risk of age related sarcopenia.3

    In the article, “Decline in Skeletal Muscle Mitochondrial Function with Aging in Humans” by John Waterlow, the study of whether aging results in increased DNA oxidation damage and reduced mtDNA abundance and mitochondrial function was tested. The study was done to determine whether or not reduced muscle mitochondrial function could contribute to age-related muscle dysfunction. This study relates to human evolution because the results will help scientist determine if there is something humans can do in future generations to reduce their vulnerability to muscle dysfunction with old age. The study was done on one hundred forty-six subjects, eighty-six of which were women and 60 being men. There were subgroups of both young and old people, the…

    One study focused on understanding the effect of insulin on muscle protein synthesis using young volunteers. Participants completed resistance exercise under multiple conditions (i.e. 12 hour fast, exercise + amino acids, exercise + amino acids +glucose, etc.) and measures of protein synthesis and breakdown were subsequently measured. Protein synthesis was enhanced and protein breakdown suppressed in all conditions including amino acids and/or glucose. However, protein breakdown was greater than protein synthesis during a 12-hour fast at rest and after exercise (i.e. without consumption of a meal).…

    Body size and compositions differ on everyone’s age, gender and just on the person’s body itself on how it reacts and functions, which raises risks for Degenerative Diseases. There are many diseases caused from how our bodies function, although we are the caretakers of our own bodies, it sometimes may be harder for some to manage and upkeep the proper amounts of food, energy, and exercise our bodies need to properly function. According to Michael Matthews, “Body composition, on the other hand, is looking at what your body is actually made of. When you step on a scale, your weight is a reflection of the amount of skeletal muscle, fat, bones, organs, blood, water, and several other more minor components in your body”. As you can see, our bodies are all different and if we do not care for them properly it can lead to degenerative diseases.…
