Filter by:Physical inactivity results in reductions in glucose tolerance and less sensitivity to insulin. If this inactivity lasts long enough it can result in insulin resistance and type 2 diabetes. A high protein diet can reduce elevated glucose levels in individuals with type 2 diabetes. Thus the investigators are interested in establishing if during a period of inactivity if a diet modification can minimize the glucose changes normally observed with inactivity. The objective of this project is to determine if short-term high protein (HP) feeding protects against the changes in glucose levels normally observed with physical inactivity. The investigators will also examine measures of blood vessel function, blood lipid and blood pressure. Twelve subjects will complete two 10 day study periods of reduced physical activity and will be studied before and after each of these study periods. For their testing subjects will have the following measurements: postprandial glucose responses to a mixed meal, 24 h free living blood pressure control during acute physical inactivity, blood lipids, changes in body composition, changes in circadian rhythm using skin temperature (ibutton), measurement of aerobic capacity (VO2 max), blood vessel responsiveness (flow mediated dilation -FMD) and changes in free living glucose levels (continuous glucose monitoring system (CGMS). Subjects will complete two conditions (high protein -HP vs normal protein - NP diets) in a randomized cross-over design. In the inactive phase subjects will reduce there steps to <5,000 steps/d while consuming either a HP or NP diet. Completion of the study will take 8-10 weeks.
The majority of today's youth do not engage in enough physical activity (PA) to maintain good health. Low PA levels are associated with poor health (e.g. diabetes, high blood pressure) and early mortality. Girls are less likely than boys to be active, and their rates of participation drop off more steeply during adolescence. Girls report many barriers to exercise, including transportation issues and feeling self-conscious about their appearance and abilities. School-based PA programs that try to improve health, mainly through aerobic exercise and education, have had a small effect to date. However, the few programs that included resistance training as the focus showed strong improvements in health related measures. In this project, we will examine the effect of a female strength and conditioning specialist on decreasing barriers and increasing the overall health of high school girls, with the delivery of in-school, girls-only resistance training programs. We will see if physical and mental health changes with the training, and how the presence of the S & C specialist affects the girls' social interactions within the school. The results will help individuals in the education sector plan programs and services to improve overall youth and school health.
The Men on the Move Study is a randomized, controlled, feasibility study designed to address the health problem of physical inactivity in older men.
The purpose of this study is to inform the integration of mobile and social media components into larger interventions aimed at increasing adherence and maintenance of physical activity. Nearly half of the US population do not meet physical activity recommendations of ≥150 minutes of moderate activity per week. The use of smartphones to "self track" data and upload that data to an online social network is becoming increasingly common and may be an effective way to motivate physical activity adherence and maintenance. We are proposing a two phase study to develop and evaluate a mobile health ("mHealth") intervention that includes the use of two existing technologies: 1) the RunKeeper mobile app to collect and upload exercise data (distance, pace, time), and 2) the RunKeeper.com online social network as a place to analyze uploaded data and engage with a coach and online community. Phase 1 (n=10) will iteratively develop the mHealth intervention and phase 2 (n=30) will pilot the mHealth intervention (participants will be randomized to either mHealth intervention (n=20) or control (n=10)) to collect feasibility, acceptability and preliminary efficacy data. All participants will attend a day-long ChiWalk/Run training to help them avoid potential injuries and meet their coach and community in-person. All participants will also be asked to wear a FitBit accelerometer from one week before the beginning of the intervention through one week after the end of the intervention to collect total physical activity data. This data will be uploaded automatically to the study data base. Primary outcomes will be total physical activity as collected by the FitBit accelerometer (and the RunKeeper mobile app for the intervention group) and secondary outcomes will be changes in psychological factors that may mediate adherence to physical activity.
Check your health is a prevention intervention designed to create awareness and action on health condition with focus at physical activity at a population-level to 30-49 years of age. It consists of a behavioural and clinical examination followed by either (I) referral to a health promoting consultation in general practice (II) targeted behavioural programmes at the local Health Centre or (III ) no need for follow-up; stratified after risk-profile. The CORE trial (Check your health) aim to investigate effectiveness on health and social outcomes of the preventive health check and to establish the cost-effectiveness according to life years gained; direct costs and total health costs. A pragmatic cluster randomised controlled trial has been established to meet the aims and in total 10.600 individuals from 35 practices have been randomized in to two groups that will be invited in 2013-14 and 2017-18 respectively. The group offered the preventive health check in 2013-14 will constitute the intervention group and the group examined in 2017 - 18 the control group. A follow up of the intervention group in 2017 - 18 will provide data for the intention to treat analysis revealing the effect. Outcome measures are level of physical activity, risk of getting cardiovascular disease, sick leave and labor market attachment.
Prescription for Health is a national program of The Robert Wood Johnson Foundation (RWJF) in collaboration with the Agency for Healthcare Research and Quality (AHRQ). A major goal of Prescription for Health is to measure the extent to which comprehensive strategies are effective in changing patient behavior and quality of life relative to four target health risk behaviors: diet, smoking, alcohol use, and physical activity. The funded projects will use a common set of survey instruments to help measure outcomes and draw overarching conclusions across projects. This study will only be analyzing aggregated data and does not have responsibility for recruitment of patients, randomization (if applicable), or interventions. Individual project designs may differ.
This feasibility study specifically addresses the issue of adapting US dietary guidelines physical activity recommendations to the population of the Lower Mississippi Delta. The hypothesis is that including a pedometer as a self-monitoring tool as part of adapted physical activity guidelines will result in greater immediate increases in physical activity (as monitored by an accelerometer) than an education program alone.
Insulin resistance is a crucial factor for the development of type 2 diabetes and a major health problem for older adults. It is the principal mechanism by which obesity is considered to increase the risk for type 2 diabetes and is a key feature of the metabolic syndrome. The elevated prevalence of obesity and type 2 diabetes in the older population has important consequences on the morbidity and mortality as well as on the economic burden on society. Controversy currently exists as to whether or not aging contributes to insulin resistance. Many potential factors confound the association between aging and insulin resistance, including obesity and physical inactivity. Ectopic lipid depositions, defined as an excess accumulation of triglycerides in non adipose tissues such as in the liver (intrahepatic lipids) and within the muscle fibers (intramyocellular lipids), are positively associated with obesity and insulin resistance. Furthermore, the accumulation of intracellular lipids is often cited as being a key determinant in the underlying mechanisms of insulin resistance. In addition of playing an important role in obesity and type 2 diabetes, these ectopic fat depositions are also observed in common conditions such as aging and physical inactivity. The intervention trial will test in skeletal muscle, liver and heart of sedentary obese volunteers, normal weight volunteers and masters athletes, the overall hypotheses that exercise improvement of fat oxidation capacity and/or decrease of damaging fat metabolites is a primary factor that predicts the improvement in insulin resistance.
Despite the acknowledgment that physical activity is important for health, there are still few population-based or school-based studies that uses the current physical activity guidelines for adolescents. Physical inactivity was defined a less than 300 min/w of moderate to vigorous-intensity physical activity practice. Previous research has shown very high prevalence rates of physically inactive adolescents and a strong association with demographic, socioeconomic and biological factors. Based on this information, the investigators are elaborating a systematic review of literature to obtain and provide more accurate information in this context.
Research has shown that a high percentage of college students do not meet recommended national guidelines for physical activity or fruit/vegetable intake. The purpose of this study was to pilot test the short-term efficacy of a one-on-one, brief motivational intervention (BMI) designed to increase physical activity and fruit/vegetable intake. It was hypothesized that participants in the BMI condition would report greater physical activity and fruit/vegetable intake at follow-up than those in an education-only control condition.
