Filter by:Performing adduction and abduction resistance exercise will increase hip bone density and strength to a greater extent than doing squat and deadlift exercise. Aim #1: To determine if doing hip adduction and abduction resistance exercise training for 16 weeks improves spine bone mineral density and hip bone mineral density and strength as determined by finite element modeling. Aim #2: To compare the effects of hip adduction and abduction exercise to squat and deadlift exercise with respect to potential changes in hip bone mineral density and strength. Aim #3: To determine if the addition of adduction and abduction exercise to squat and deadlift exercise promotes an "additive" effect with respect to changes in spine bone mineral density and hip bone mineral density and bone strength.
To evaluate the effect of an experimental oral nutritional supplement containing AN777 compared to another oral nutritional supplement in a malnourished, elderly population.
Sarcopenia, the age-related decline in muscle mass and function (widely recognized as "frailty"), is increasingly being appreciated, primarily in the research environment. Interventions to prevent or treat sarcopenia can be anticipated to reduce falls, fractures and thereby to facilitate independence and improve quality of life for older adults. Unfortunately, there is no current consensus definition of sarcopenia, thereby impeding clinical recognition and treatment. It has been advocated that low appendicular (arm and leg) lean mass, as measured by DXA, be utilized as a clinical diagnostic tool to define sarcopenia. While such an approach is possible, however, muscle strength loss is more rapid than mass loss, indicating deterioration of muscle "quality." Muscle quality may be affected by changes at the neuromuscular, cellular or subcellular levels; parameters not detected by measuring mass alone. Clearly, tools evaluating muscle performance, not simply mass, are needed to optimally identify, and subsequently monitor, treatment of older adults with sarcopenia. While current tests of muscle power/function (e.g., chair-rising, self-selected gait velocity, etc.) do correlate with functional limitation in older adults, these existing tests have limitations in that they cannot be performed in all people, may have "yes/no" results rather than a continuous scale and may not be highly precise. Thus, improved muscle function assessment tools are needed, both clinically and in research venues. Jumping mechanography is very likely one such methodology.
The purpose of the study is to examine the effects of resistance training on the reasons (mechanisms) underlying the development of fatigue, muscle weakness and wasting (sarcopenia), and impaired physical functioning (poor balance and walking) associated with breast cancer survivorship.
The present study is designed to investigate whether timed protein supplementation will increase skeletal muscle mass in the frail elderly population.

The purpose of this study is to determine if taking the pain reliever acetaminophen (ACET) interferes with some of the benefits of weight lifting on muscles and bone density in older men.
When we age, we lose muscle. It is not exactly clear why this happens, but we do know that this muscle loss can increase health risks and lead to health problems. Lifting weights (i.e. performing resistance exercise) and proper nutrition, in particular eating enough high quality protein, can help slow the loss of muscle mass or potentially even reverse it. Protein and resistance exercise are thought to do this by stimulating your muscle to make more proteins and/or potentially by slowing down the rate at which your body breaks proteins down. Whey protein is a high quality protein isolated from milk and is known to stimulate new protein synthesis for all proteins in your body. However, to date, the effect that whey protein has on muscle protein synthesis, particularly in the elderly has yet to be determined. Thus the purposes of this study are: 1) to determine if whey is an effective source of protein that will stimulate muscle protein synthesis in the elderly, similar to what we have previously seen in young persons; 2) to determine the smallest amount of whey protein to consume to maximally stimulate your muscle to make new proteins; 3) to see if performing resistance exercise will augment the increase in new muscle protein synthesis with whey consumption; and 4) to try and found out if whey is more effective than soy protein in stimulating new muscle protein synthesis and suppressing muscle protein breakdown in the elderly, similar to what we have previously seen in young persons
As we age, we experience a reduction in muscle and bone which inevitably decreases strength and the ability to perform tasks of daily living such as gardening, carrying groceries, and climbing stairs. Health costs associated with aging muscle and bone loss are in the billions of dollars. With the projected increase in life expectancy, the incidence of muscle and bone loss will rise and further drain the healthcare system, with greater need for hospitalization, treatment, and rehabilitation. Without effective strategies to counteract aging muscle and bone loss, we may face a healthcare crisis in the future. Creatine, a compound found in red meat and seafood, increases creatine phosphate stores in muscle, providing increased energy during high-intensity exercise. Short-term (i.e. 3-4 months) resistance-exercise and supplementation with creatine, have been shown to have a favorable effect on properties of aging muscle and bone. However, the longer-term (i.e. 1 year) effects of these interventions are unknown. Therefore, the purpose of this innovative research is to determine the longer-term effects of resistance-exercise and creatine supplementation (0.1g•kg-1) in older adults. The primary dependent variables to be assessed will include muscle hypertrophy, bone mineral and bone geometry, strength, and urinary and blood indicators of liver and kidney function. This innovative, multidisciplinary research will help contribute to the successful pursuit of prolonged independent living by improving aging musculoskeletal health for older Saskatchewan adults. Saskatchewan provides a relevant setting for this research, given the higher percentage of older adults (15%), compared to the national average (12%). We hypothesize that creatine supplementation will increase muscle mass, strength, and bone mineral density more than placebo.
The purpose of this study is to determine whether older adults (ages 65-89) who consume the dietary supplement Juven (Abbott Laboratories) versus placebo for 6 months will demonstrate increases in fat-free mass, muscle volume,and physical function.
