The prevalence of sarcopenia is high, with ≥ 45% of the U.S. population aged 60 years or older sarcopenic. Some possible causative factors include a decline in muscle protein synthesis, inactivity, hormonal changes, pro-inflammatory conditions, and reactive oxygen species within the muscle mitochondria, which may all be exacerbated by inadequate nutritional intake. Since dietary protein is targeted to muscle and muscle mass represents the largest tissue in the body, protein nutrition plays a significant role in muscle metabolism.\n\nSPECIFIC AIMS The specific aim of this proposed study is to determine the effect of PS-IPC supplementation on muscle mass, muscle strength, muscle quality, and inflammatory / immune markers in healthy older adults. Subjects scoring 4 - 10 on the Short-Physical Performance Battery and aged 60-85 years will consume PS-IPC supplements or placebo three times daily for 12 weeks.\n\nHYPOTHESES\n\n1. Subjects consuming PS-IPC will have a greater increase in muscle mass and muscle strength compared to a control group consuming a placebo supplement.\n2. Subjects consuming PS-IPC will demonstrate a greater increase in the fractional rate of muscle protein synthesis compared with a placebo control group.\n3. Subjects receiving PS-IPC will have a reduction in plasma concentrations of various inflammatory markers of immune function, compared to subjects consuming the placebo.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '60 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* BMI of less than or equal to 35 kg/m2, be weight stable (+/- 5 kg) over the previous 4 months (via oral report), report the absence of alcohol or drug abuse, require minimal help in performing activities of daily living, and have a Short Physical Performance Battery score of 4 - 10.\n\nExclusion Criteria:\n\n* Subjects with acute or chronic disease or who may be using drugs that might interfere with skeletal muscle metabolism / function or immune function will be excluded from participation.
