Filter by: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.
The purpose of this trial is to study the effects on exercise capacity, physical activity, inflammatory markers and quality of life of supplemental ambulatory oxygen, to be used during physical activity, in patients with COPD who are normoxic at rest but hypoxemic during a six-min walk test. Our hypothesis is that if patients are able to use supplemental oxygen they will be more physically active and thereby improve health related quality of life.
Primary care centres are a key setting to treat people with overweight and moderate obesity. There is growing evidence that sitting for a long time is negatively associated with people's health. Interventions with the aim of reducing daily time of sedentary activities can be an effective strategy to increase daily energy expenditure. To improve the effectiveness of programmes promoting physical activity in primary care we need some clear action protocols that can be easily integrated in the daily routines of primary care professionals. Objective. The objective of the study is to evaluate the effectiveness of a six-moth primary care intervention to reduce diary hours of sitting time in overweight and obese sedentary patients, as well as to increase their weekly caloric spend. Methods. The design of the study is a simple randomized controlled trial. Ten primary care centers will be invited to participate and will be randomized into control (CG) and intervention group (IG). Each professional will randomly invite to participate voluntarily moderate obese or overweight patients (BMI: 25-34,9 kg/m2) of both sexes, aged between 25 and 65 years old, who are 6 or more than 6 hours daily sitting. A total of 400 subjects (200 individuals in each group) are needed. In addition, 50 subjects with fibromyalgia will be included in the study to know the feasibility of the intervention among them. The main dependent variable (sitting times) will be measured with an ActivPAL during first and last intervention week. There will be a follow up after 3, 6 and 12 months of the end of the intervention. Other variables included in the study: number of steps walked, subjective level of physical activity, weight, height, BMI, skinfolds, waist circumference, triglycerides, total cholesterol, (LDL and HDL), glucose, sociodemographic variables, blood pressure and quality of life related to health. A descriptive analysis of all variables and a multivariate analysis to assess differences among intervention and control group will be undertaken. Multivariate analysis will be carried out to assess time changes of dependent variables. All the analysis will be done under the intention to treat principle.
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.
This study targets two major risk factors for cancer; is designed to treat the behaviors on a population basis, using proactive recruitment strategies; intervenes on multiple behaviors simultaneously, thereby producing greater impacts for cancer prevention; utilizes one of the most promising approaches to low cost population based interventions for health-related behavior change, namely the internet; and develops and tests a promising new approach to increasing the utilization and effectiveness of internet-based interventions, relational agents. The primary aims are: (1) To develop and assess the effectiveness of a tailored internet intervention on a national sample; (2) To develop and assess the effectiveness of the internet intervention enhanced by a relational agent; and (3) To determine if the intervention with the relational agent can outperform the regular tailored internet intervention.
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.
