Filter by:The purpose of this study is to compare the effects of different trainings on cognition and physical performances in elderly over 80 years.
The aim of this study is to devise a sufficiently high intensity training program that provided an optimal stimulus to remove the peripheral factors known to reduce functional capacity, and can be cardiovascular and orthopedically well tolerated by the elderly. Findings from study laboratories have suggested that a regional specific training stimulus (RSTS) results in rapid improvements in both vascular and muscular function. RSTS is a novel combination of resistance training and aerobic training applied simultaneously, and in a serial manner, to specific regions of the body. It involves high-intensity and frequency muscle contractions, generating a targeted exercise stimulus, without producing excessive cardiovascular or orthopedic stress. The hypothesis is that initiating training with RSTS at multiple, strategically selected peripheral sites, in a serial manner will elicit local vascular and muscular changes, thereby preparing individuals at elevated risk of losing independence, to respond and progress more favorably to whole-body exercise.
The purpose of this study was to determine whether the installation of sit-stand work stations could lead to decreased sedentary time and increased physical activity during the workday among sedentary office workers.
Here we tested if statins or exercise plus statins had a greater capacity to lower metabolic syndrome risk factors in sedentary individuals with at least 2 metabolic syndrome risk factors. We also examined if statins impacted exercise response for mitochondrial content in muscle or aerobic fitness.
The importance of exercise for weight control is well documented; however if exercise results in an increase in food intake, the beneficial effect of exercise may not be seen. This study addresses a gap in the current literature and examines why some people eat more after exercise and why some people eat less and also examines whether these responses are consistent over time. Participants in this study will be asked to come to our center on 7 different occasions over a 3-4 month period. The first visit will be an assessment visit where body weight and body composition will be measured, questionnaires will be completed, and an exercise test will be performed. During the remaining 6 visits (3 pairs of sessions with visits in each pair separated by 48-96 hours) the procedures will be nearly identical. Upon arrival at our center, participants will consume a meal replacement, complete a series of questionnaires and then either rest or walk on a treadmill for 30 minutes (3 days will be resting and 3 will be exercising). One hour following the exercise/resting session, individuals will be given access to a buffet of food, unaware that their food intake will be monitored. All food will be weighed and measured before and after the eating period and the amount of food consumed after each pair of exercise and resting conditions will be compared to one another. It is hypothesized that the difference in food intake will be consistent across pairs of testing sessions. Findings from this study will help us to better understand the relationship between exercise and food intake and may ultimately lead to future studies that can address the clinically significant question of why some individuals gain weight and others lose weight when engaging in exercise training programs. Findings from this study may also help to develop exercise programs that maximize the beneficial effect of exercise on body weight.
The present study aims to initially test a community dog walking intervention that addresses individual, interpersonal and community factors associated with dog walking. The study will be conducted in two cities, Worcester and Lowell, as a collaboration between investigators from UMass Medical School and UMass-Lowell.
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.
The purpose of this study is to assess whether a 6-month multilevel physical activity intervention can significantly increase physical activity levels in sedentary adults, 65 and older, living in Continuing Care Retirement Communities (CCRCs). Sedentary residents (N=320)in 16 CCRCs will receive the multilevel MIPARC intervention or a control health education program for 6 months. A group randomized control design will be employed with site as the unit of randomization. The intervention is delivered through group sessions, phone calls, printed materials, tailored signage and mapping and targeted peer led advocacy efforts.
Aging is associated with declines in aerobic capacity, exercise tolerance, and functional endurance that lead to physical disability and loss of independence. Furthermore, the existing high prevalence of obesity in the elderly is greatly exacerbating these aging-related declines in function. To date, regular exercise is the only known therapy to consistently improve aerobic function, and perhaps delay the onset of disability. Although aerobic exercise training does benefit both aerobic capacity and endurance even in obese persons, some data show that the maximal efficacy of exercise for improving aerobic function is blunted by obesity. In addition, our preliminary data show a potential dose-response benefit of concomitant fat loss on exercise-induced improvements in aerobic function. Thus, combining an exercise intervention with caloric restriction resulting in fat loss may be more efficacious for improving aerobic function than exercise alone in obese elderly, a population at high risk for disability. The purpose of this study is to determine whether the amount of fat loss (achieved through controlled underfeeding) affects the magnitude of improvement in aerobic function (maximal aerobic capacity and endurance) in response to a standardized exercise training stimulus that follows current recommendations for older persons.
Abdominal obesity, which is affected by a lack of physical activity and excess weight, put people at an increased risk of cardiovascular disease. This study will compare the effects of two different dietary approaches to weight loss, each combined with exercise, for their effects on cardiovascular factors that are early predictors of future cardiovascular disease in overweight and obese people with excessive weight around their waist. The two diets are a low-carbohydrate versus a more traditional low-fat, low calorie diet.
