Filter by:The primary purpose of this study is to examine the effectiveness of the current resistance training guidelines for older adults proposed by ACSM/AHA to improve physical function in individuals with reduced physical abilities. A randomized controlled intervention trial will be used to compare change in physical function pre- and post-intervention between a treatment group receiving the minimum recommendations of the guidelines and a control group asked not to change their physical activity participation. To better understand the clinical significance of such an occurrence, a secondary purpose was to determine if older adults with reduced physical abilities who adhere to the recommended intervention dosage will experience a change such that they can be reclassified to a more favorable level of functioning. It is hypothesized that the minimum recommended dosage of the guidelines would be sufficient to both improve physical function and improve functional classification in older adults with reduced physical abilities.
A growing body of evidence suggests that vitamin D status is important in biologic processes involved in the maintenance of physical function. To advance the investigators understanding of the role of vitamin D in physical function, the investigators will conduct a feasibility pilot study to collect key information to help design a full-scale randomized trial to determine whether vitamin D supplementation will delay declines in physical function. The primary goals of the pilot study are to determine cost-effective strategies for identifying persons at high risk for functional decline with insufficient vitamin D levels, determine the serum vitamin D response to a vitamin D supplementation regimen designed to attain sufficient vitamin D levels, and provide preliminary data of key functional measures (balance, physical performance and muscle power) for the future larger study design. A secondary goal is to begin to examine potential mechanisms by which vitamin D supplementation may enhance physical performance by exploring the effects of vitamin D supplementation on changes in skeletal muscle gene expression.
To evaluate the safety and efficacy of the Lichtenstein's hernioplasty using Infinit® PTFE Mesh, and to compare it with the traditional Lichtenstein procedure performed with polypropylene mesh.
The broad aim is to determine efficacy of a weight loss diet higher in protein and lower in carbohydrate combined with low intensity exercise to favorably impact body composition, bone health, physical function, metabolic disease and quality of life compared to a conventional higher carbohydrate diet in overweight women over age 60.
The purpose of this study is to evaluate the effects of a combined aerobic and resistance exercise program in breast cancer survivors.
The purpose of this study is to compare two exercise programs to determine how well they help older adults make exercise a regular habit after 9 months.
Projections from NHANES III indicate that approximately 12,000,000 U.S. adults ≥ 60 years of age have vitamin D insufficiency (serum 25(OH)D < 50 nmol/L). A growing body of evidence suggests that vitamin D status may be important in biologic processes involved in the maintenance of physical function. To test the hypothesis that vitamin D insufficiency is associated with poorer muscle strength and physical performance, we propose to evaluate the role of vitamin D status (serum 25(OH)D) on physical function and falls in the CHS All Stars cohort, a population of advanced age. The specific aims are as follows: Specific Aim 1. To describe the prevalence and correlates of vitamin D insufficiency in adults of advanced age. Specific Aim 2. To examine the cross-sectional association between vitamin D status and muscle strength (leg and grip strength), physical performance (3 m/15 ft walk time, repeated chair stands, and standing balance), self-reported physical function (mobility, ADL and IADL disability), and falls. Specific Aim 3. To examine the longitudinal association between vitamin D status at baseline and incident disability (mobility, ADL and IADL disability) over 3 years of follow-up. Research Hypotheses: Low vitamin D status (25(OH)D < 50 nmol/L) will be associated with (a) lower levels of muscle strength and physical performance; (b) higher levels of self-reported limitations in physical function and falls; and (c) greater odds of incident disability.
