Filter by:Coordinated project whose objectives are: a) to test the effectiveness of a promotion of physical activity intervention (MOVI-KIDS) on preventing obesity; and b) to improve the academic performance in both children with and without attention deficit hyperactivity disorder (ADHD)
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.
Encouraging greater levels of physical activity is critical to improving health among Americans, who are largely sedentary. Neighborhood parks are resources for physical activity that are available to most Americans within a couple miles of their homes, yet many residents are unaware of the programs and facilities available. Previous research indicates that park use is related to park programming and outreach. Because funding for parks is limited, low-cost interventions are needed to attract more people to parks to engage in moderate-to-vigorous physical activity. While many community-based organizations would like to invest in efforts that increase physical activity, few low-cost park programs are documented to be both scalable and cost-effective. Effective programs that can be replicated to make population-level impacts are needed. The goal of this study is to develop and test 2 low-cost community-level approaches, free exercise classes vs. a frequent user program, to promoting physical activity, singly and in combination, in 48 park settings in Los Angeles low-income neighborhoods.
Physical activity is a powerful lifestyle factor that on average reduces risk for development of diabetes and cardiovascular disease. Nevertheless, investigators have demonstrated that following supervised endurance exercise training, 20% of subjects show no change in fitness and 30% demonstrate no improvement in insulin sensitivity. Our concept is that by using molecular profiling of blood/muscle samples investigators will develop personalised lifestyle intervention tools. Further, revealing the biological basis for a variable metabolic or cardiovascular response to exercise will enable us to propose new targets and biomarkers for drug discovery efforts directly in humans. Using our established OMICS approaches (RNA, DNA and Metabo-) investigators will generate classifiers that predict the responses to exercise-therapy (fitness and insulin sensitivity). Classifier generation is a statistical strategy for diagnosis or prognosis. Critically, investigators have a large human tissue biobank, including subjects with insulin-resistance; young to elderly males and females, as well as twins. Our SME partner has significant intellectual property and capacity in the field of bio-prediction, with a proven track-record of collaboration with the team and product development. Investigators will add to the diversity of our biobank by carrying-out an exercise intervention study using a novel time-efficient strategy that investigators have recently proven to be effective in reducing insulin resistance in sedentary young people and in middle aged obese subjects. A time-efficient protocol is a critical as lack-of-time is a key reason for not maintaining physical activity levels. Finally, investigators have a novel out-bred rodent model that replicates high and low exercise training responses and investigators will establish its suitability for future drug screening purposes. Because of these substantial pre-existing resources investigators believe that our project has a very high probability of delivering on its goals of improving the healthcare of European citizens.
Despite their importance, health-related behaviors are hard to change. Among behaviors, physical activity is associated with protection from multiple diseases. People who are physically active have lower risk for heart disease, stroke, type 2 diabetes, depression, and some cancers with associated dose-dependent reductions in cardiovascular and all-cause mortality. However, most US adults do not meet CDC physical activity guidelines. Sedentary work behavior in industrialized nations is likely a contributor to this problem. Current low-technology strategies for encouraging lifestyle change are disappointingly ineffective and are highly resource intensive. Systematic reviews of the literature show mixed evidence for using activity trackers (i.e., pedometers) and a limited body of evidence for text messaging in preventive health care. However, prior studies have not integrated digital activity tracking with mobile phone text messaging feedback. Given 91% of adults in the United States now use a mobile phone, and 56% a smartphone, this represents a potentially widely applicable avenue for therapeutic intervention. There is growing interest in leveraging mobile health (mHealth) technologies to improve health behaviors in the general population. The investigators propose to conduct a blinded, randomized mHealth trial of digital activity tracking and smart texting to promote physical activity.
The purpose of this study is to test the overall effects of incentives on physical activity among older taxi drivers, and whether mental accounting exists in this context.
Can participation in group physical activity, such as a community-based organized group walk, help adult diabetes patients develop a physically active lifestyle? Can such engagement ultimately lead to an improvement in hemoglobin A1c? To address this question, the investigators have designed this pilot study with the aim to investigate the effect of community-based group walks among Joslin adults with diabetes on the development of a physically active lifestyle and glycemic level. The investigators hypothesize that participation in group walking events helps Joslin adults with diabetes engage in physical activity and improves glycemic control.
This pilot study will assess whether a supported pedometer-based walking program is helpful in maintaining physical activity for breast and head-and-neck cancer patients who are undergoing radiation therapy. Follow-up monitoring sessions will be scheduled to help provide support for physical activity during radiation therapy. We will also examine the relationship of physical activity and quality of life outcomes to help inform future research.
Usability of the PALMS system, validity of the PALMS system and added value to an existing cohort study. Hypothesis: Addition of GPS device and use of PALMS system will allow researchers to better examine place-based interventions.
