简要总结
The primary objective of this study is to evaluate changes in functional status that result from an Exercise-Nutrition Program (ENP) targeted toward older adults residing at senior housing facilities.
- The primary hypothesis is that over the 6-month intervention period subjects in the intervention group will realize significant improvements in lower extremity function compared to a control group.
Secondary objectives
To evaluate changes in nutritional status that result from the ENP.
- The secondary hypothesis is that subjects in the intervention group will realize significant increases in circulating insulin-like growth factor-1 (IGF-1) and 25-hydroxy vitamin D (25(OH)D) and demonstrate improvements in nutritional status compared to a control group.
To evaluate changes in inflammatory status that result from the ENP.
- Subjects in the ENP group will exhibit reduced concentrations of circulating interleukin-6 (IL-6) compared with the control group.
To evaluate changes in psychosocial factors that result from the ENP
- The related hypothesis is that over the 6-month intervention period subjects in the intervention group will increase exercise self-efficacy, intrinsic motivation to exercise, and satisfaction of psychological needs compared to a control group.
- Additionally it is hypothesized that subjects in the intervention group will realize improvements in mood and quality of life compared to a control group.
To assess the feasibility of conducting the Exercise-Nutrition Program in a senior housing facility setting.
详细描述
Older adults are the fastest growing segment of the population in many countries around the world, and the maintenance of independence has emerged as a major public health priority. Although a significant decline in physical function was once considered an inevitable consequence of aging, many studies have demonstrated that targeted exercise programs can dramatically improve physical function, even into advanced age. There is also evidence that appropriately timed protein intake is important for exercise recovery and the growth and maintenance of lean body mass. Other nutrients may be important to muscle strength and function as well. Yet many older adults have poor nutritional status. A combined exercise and nutrition program for functionally at-risk older adults, conveniently offered in the senior housing facilities where many reside, has great potential to improve functional status and quality of life in this population.
