Brief Summary:
The study use a double blind, placebo-controlled design enrolling male and female subjects between 55-90 yo to evaluate the effect of daily consumption of a cocoa beverage on anthropometric, metabolic, oxidative stress, physical performance and quality of life.

Sarcopenia Frail Elderly Syndrome Other: Placebo Other: Flavonoids Dietary Supplement: No Flavonoids Not Applicable

Detailed Description:

The study use a double blind, placebo-controlled design enrolling male and female subjects between 55-90 yo randomly assigned to consumption of a flavonoid rich mixture (flavonoids; F), alkalinized cocoa which eliminates flavonoid content (no flavonoids; NF) or placebo. All beverages had similar physical characteristics and flavor. Cocoa beverages were provided in individual sachets containing a dry powder that was reconstituted with water just before consumption. Subjects were instructed as above to maintain their usual lifestyle, to limit intake of high caloric foods and flavonoid-containing foods and beverages, and to walk for 30 min/day.

To determine the effect of flavonoids, study evaluates anthropometric measures, metabolic parameters as glycemia and a lipid profile (triglycerides, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol). To evaluate oxidative stress damage as lipid oxidation is measured with the malondialdehyde (MDA) assay. Protein carbonylation is measured using an assay for detection of carbonyl groups that relies on 2,4-dinitrophenylhydrazine (DNPH) as a substrate. The investigators also evaluate interleukin-6 and tumor necrosis factor levels.

For physical performance is evaluated the handgrip strength, and mobility assesment with the following test: Six-minute walk test, two-minute step, sit-up test and the up & go test.

The investigators also assessed quality of life using the Health Related QoL (EQ-5D) questionnaire.
