Filter by:This study will be investigating an innovative and exciting way to increase physical activity in children between the ages of 9 and 12 years old. Families will be provided with a state-of-the-art exercise bike and video game console to have in their homes. The video games will provide a variety of play including racing, puzzle solving, collaborative play, team play and competitive play. We will be comparing whether a 'multi-player' condition has a greater adherence compared to a 'single-player' condition.
Due to disparities in childhood obesity, interventions for physical activity promotion and obesity prevention for low socioeconomic and racial/ethnic minority children and adolescents are vital to address disparities across the lifespan. Mobile health applications (mHealth apps) are a rapidly growing and promising approach for interactive and individualized interventions for disease prevention. Smart phones are a promising platform to reach racial/ethnic minority and lower income groups due to high rates of adoption of smart phone usage among these groups When paired with wearable sensing devices, mHealth apps for smart phones can collect data and provide feedback to users in real time. In a study among university students regarding mHealth apps, participants expressed interest in the "ability to record and track behaviors and goals and the ability to acquire advice and information 'on the go'". For physical activity in particular, wearable physical activity monitors designed for consumers that objectively measure and display data related to an individual's physical activity on smart phones through mHealth apps have become widely available and affordable. These wearable devices wirelessly upload data and provide users with physical activity data visualization and goal setting features that can be customized for each user via internet-based applications for smart phones, tablets, and/or computers. While several internet-based behavioral programs to promote pediatric physical activity have been reported in a recent review, none examined wearable sensing devices coupled with mHealth apps. Similarly, a 2013 review on mHealth technologies for physical activity assessment and promotion reported no studies that used wearable sensing devices for intervention delivery and called for research to evaluate feasibility. The Primary Goal is to conduct a pilot randomized controlled trial (RCT) of the FitBit Flex, a popular wearable physical activity sensing device that allows data visualization and goal setting on smart phones. The target population will be adolescents ages 14-18 years old in the Seattle-metro area (n=40) with approximately 50% from low income households or belonging to a racial/ethnic minority. We will target this older age group since they have the lowest levels of physical activity among the pediatric population. This pilot study will provide feasibility and preliminary data for a future R01-funded RCT of the Flex mHealth device and app.
The aim of this study was to evaluate the impact of a classroom teachers' educational intervention on 1st and 2nd grades children's physical activity level and energy expenditure during physical education classes in elementary public schools, in São Paulo, Brazil.
The purpose of this study is to analyse if a multidisciplinary approach including peers is effective in the treatment of obesity in adolescence.
US children's active commuting to school (ACS; walking or cycling to school), previously common (48% in 1969) is now uncommon (13% in 2009). This decline coincided with the obesity epidemic, which disproportionately affects low-income and ethnic minority children. Programs to increase children's moderate-to-vigorous physical activity (MVPA) and lower obesity and related chronic disease risk are necessary. The Bicycle Train is an innovative program in which children cycle to and from school led by adults. Bicycle Trains provide another option for ACS, especially for children who live too far to walk to school. No randomized controlled trials (RCT) have evaluated Bicycle Trains and children's ACS or MVPA. Increasing the percent of children who cycle to school is sub-objective PA-14 of US Healthy People 2020. The Primary Goals are to (a) conduct a pilot cluster RCT of a Bicycle Train program among low-income, ethnic minority 4th and 5th grade children and (b) collect concurrent accelerometer and GPS data and validate algorithms to identify and measure physical activity intensity and duration for children's cycling compared to heart rate monitors. Our Specific Aims will be to: SA1) evaluate among 80 4th and 5th grade ethnic minority children the feasibility of a pilot cluster RCT of a Bicycle Train program for (a) recruiting participants for a planned full-scale cluster RCT (b) promoting their participation, and (c) identifying barriers/facilitators to their participation; and SA2) validate algorithms examining concurrent accelerometry and global positioning system (GPS) data to identify and measure children's physical activity intensity and duration while cycling compared to the criterion standards of heart rate monitoring and direct observation Feasibility Criteria (FC): As recommended for pilot studies, in which the main goal is to test feasibility of a research protocol, a fully powered R01-funded cluster RCT will be determined to be feasible if: FC 1) We successfully recruit 80 low-income 4th and 5th grade children for the pilot Bicycle Train cluster RCT FC 2) The intervention children participate in the Bicycle Train program on average twice/week or more FC 3) Algorithms analyzing concurrent GPS and accelerometer data have high agreement, i.e. >90% agreement, with heart rate data/direct observation in distinguishing children's cycling-related physical activity duration and intensity from other physical activities and riding in a motor vehicle
Lack of physical activity is associated with negative health outcomes, including obesity, diabetes, and cardiovascular disease. There are calls from NIH and medical organizations to integrate the use mobile devices, such as smartphones, to provide "e-health" interventions to patients in their daily life. Referred to as Ecological Momentary Interventions [EMI], these innovative mobile methods provide an opportunity for researchers and clinicians to offer tailored intervention material to people at specific times and in specific settings when they may be most in need of such support. To our knowledge no study has used objective ambulatory assessment data to deliver EMI. This preliminary work is to demonstrate the feasibility, and test preliminary efficacy, of using a Bluetooth accelerometer to provide real-time feedback on a smartphone to increase objectively measured steps (i.e., increase activity). A within-person design will be used, including assessment, intervention, and follow-up phases. During the assessment phase objective physical activity (using accelerometers) will be collected. In the intervention phase participants will also receive real-time feedback throughout the day regarding their total steps and personalized step goals. Objectively measured steps and disease status measures will be used to evaluate efficacy.
The participants are twelve small or middle-sized companies. Baseline information about the company's practices and employees' physical activity is collected in November 2013 with questionnaires and accelerometers. A team is nominated in each company to develop company's practices in relation to promoting physical activity and reducing sedentary behavior among employees. The teams are supported with materials and meetings and the opportunity to obtain physical activity services from the regional offices of the Finnish Sports Confederation. The development process is carried out in Fall 2013 and the actions to promote physical activity and to reduce sedentary behavior are implemented in the companies during spring and fall 2014. The follow-up evaluation with the same measures as at baseline will be conducted in November 2014 and depending on financing possibly also in November to assess the maintenance of the actions.
To compare the effect of mini-exchange-room and usual care on physical activity and quality of life in peritoneal dialysis (PD) patients through a randomized controlled study. A total of 80 incident CAPD patients with age of 18~80 years old will be enrolled, who are medically stable and regularly followed up. The one group perform traditional PD procedure (G1), and the other group will utilize disposable mini-exchange-room group (G2). Two groups will be followed for 6 months. Biochemistry data, types of space for bag exchange, physical activity and quality of life will also be collected for all subjects at the 3rd and 6th month. During the study period, peritonitis episode, acute comorbidity and hospitalization will be recorded. The change of physical activity, quality of life and peritonitis rate will be compared between the two groups.
Regular physical activity is one prominent health-protective behaviour which might increase with the help of self-regulatory strategies such as action planning. The aim of this randomised controlled trial is to examine changes in daily moderate physical activity in couples following (a) a dyadic planning intervention, (b) an individual planning intervention or (c) a no-planning control condition. Changes in daily physical activity will be examined over a period of one year. It is assumed that target persons from couples receiving a dyadic planning intervention will show greater increases in daily physical activity than target persons from couples receiving an individual planning intervention. For couples receiving a dyadic planning intervention or an individual planning intervention, it is hypothesized that target persons will show higher increases in daily physical activity than target persons from couples participating in the no-planning control condition.
The aerobic fitness is important for mountain bikers, but riders should also be able to generate maximal and supramaximal efforts in some crucial phases of the competition. Although there is an increase interest in high-intensity aerobic training, to investigators knowledge, there are no studies examining the effects of interval (INTV) or intermittent training (INTM) in mountain bikers. The aim of this study was to compare the effects of INTV and INTM on aerobic fitness variables (peak power output, Wmax, lactate threshold, and onset of blood lactate accumulation) but more importantly on performance as measured using a controlled mountain bike race, i.e. simulation. The investigators hypothesized that INTV and INTM training were equally effective in improving Wmax, Lactate threshold and onset of blood lactate accumulation, but INTV was superior in enhancing performance in mountai bike race simulation.This hypothesis is due to studies that have shown higher gains in performance with long duration of aerobic high intensity interval training in comparison to the shorter training at a higher intensity.
