Filter by:There is increasing evidence that the acid-base balance of diet plays an important role in the health of bones and muscles. An excess of acid in the body can result in calcium loss and muscle breakdown. Potassium bicarbonate, a base supplement, can neutralize acid within the body. The purpose of this study is to determine the effectiveness of potassium and bicarbonate, alone and combined, at reducing bone loss and preventing muscle wasting in older adults.
The purpose of this study is to examine the effect of dietary cholesterol administered as whole egg or egg white (control)on muscle mass gain with resistance training in a young old population of men and women (age 50-69). It is hypothesized that dietary cholesterol will be significantly associated to muscle mass gain.
The purpose of this study is to determine whether testosterone replacement in older men with low testosterone levels will increase muscle strength, improve physical performance and overall sense of well being, and reduce fatigue.
The study aims to determine the effects of testosterone on muscle function, mobility, activities of daily living and overall quality of life
The purpose of this study is to determine the relationship of deficiencies in testosterone and growth hormone to loss of muscle mass (sarcopenia) and functional impairment during aging and whether there is an interaction of these two hormone systems in maintaining normal skeletal muscle mass and physical function.
Health promotion in the elderly has been a major recent public health concern. Sarcopenia is a term utilized to define the loss of muscle mass and strength that occurs with aging. It has been demonstrated to be associated with decreased functional capacity among the elderly. The magnitude of the public health problem posed by sarcopenia is not yet established. The purposes of this study are to investigate sarcopenia and its relationship with functional status in elderly Taiwanese community-dwellers, and to develop the preventive strategy for sarcopenia in the elderly. Firstly, the investigators will recruit 100 volunteers (aged 18-90 years old) to participate in this study. All of the participants will receive bioelectric impedance analysis (BIA), muscle strength and endurance assessment, physical activity level assessment by a seven-day recall questionnaire, protein intake assessment, cognition evaluation (Mini-Mental State Examination) and functional status assessment by the Functional Independence Measurement (FIM) questionnaire. A multiple regression model will be used for statistical analyses. Then, this project will be used to evaluate the efficacy of a 12-week supervised resistance strengthening exercise program for sarcopenia in the elderly. Participants who are defined as having sarcopenia from the previous examination will be randomized into either the exercise or control groups. Subjects in the exercise group will receive resistance strengthening exercises 3 times per week for 12 weeks. All measurements will be performed as described above. The investigators expect that resistance exercises are effective in offsetting age-related decline of muscle mass and strength in the elderly.
Background: Menā„65 years often produce lower levels of testosterone, meaning there is less testosterone circulating to the tissues of the body. This is associated with negative effects on muscle strength, bone density, sexual function, mood, and the ability to think to the best of one's ability. Testosterone replacement therapy often involves injections, patches, or gels that help to raise circulating testosterone levels, but these therapies often have side effects because they lead to imbalance of other hormones. Researchers have been studying the effectiveness of anastrozole, a drug that can lower estrogen levels while simultaneously increasing testosterone levels, as a treatment for the negative effects of decreased circulating testosterone levels that occur naturally with aging. Objectives: To evaluate whether anastrozole is as effective as testosterone gel in improving bone and muscle strength, hormone levels, and brain function in men over 65 years of age. Eligibility: Healthy men at least 65 years of age who have low levels of testosterone. Design: The study involves six study visits over a total of 12 months: screening, baseline, 6 weeks, 3 months, 6 months, and 12 months. All participants will receive calcium and vitamin D supplements to take daily, and will be randomized to one of three groups:Testosterone gel and placebo tablet, Anastrozole tablet and placebo gel, Placebo tablet and gel. Participants will have the following tests at each specified visit:Screening: Blood tests and rectal ultrasound to evaluate the prostate;Baseline: Blood and urine tests; growth hormone levels, muscle strength, bone density, and balance evaluation; imaging studies; cognitive testing; and questionnaires on quality of life, sexual function, depression, and urinary symptoms;Six weeks: Blood tests and dose adjustment of the gel or tablet;Three months: Blood and urine tests; growth hormone, muscle strength, bone density, and balance evaluation; and questionnaires on quality of life, sexual function, depression, and urinary symptoms;Six months: Blood and urine tests; muscle strength, bone density, and balance evaluation; cognitive testing; and questionnaires on quality of life, sexual function, depression, and urinary symptoms;Twelve months: Blood and urine tests; rectal ultrasound; muscle strength, bone density, and balance evaluation; imaging studies; cognitive testing; and questionnaires on quality of life, sexual function, depression, and urinary symptoms.
