Filter by:The purpose is to establish feasibility of delivering an individually-tailored, behavioral intervention to manage gestational weight gain [GWG] that adapts to the unique needs and challenges of overweight/obese pregnant women [OW/OBPW] and will utilize control systems engineering to optimize this intervention; in other words, make this intervention manage GWG in OW/OBPW as effectively and efficiently as possible.
The aim of this research is to evaluate the efficacy of contextually tailored activity suggestions and activity planning for increasing physical activity among sedentary adults.
The aim of this school-based cycling intervention called "Cycling and Walk to School" (PACO, for its Spanish acronym) will be to examine their effects on adolescent's cycling to and from school and physical activity (PA). This study will also examine the effects of this intervention in several active commuting to and from school (ACS)-related variables belonging to Self-Determination Theory (SDT) and Social-Ecological Model (SEM).
This work aimed to examine the effects of drinking an "energy drink" upon (i) short-term maximal performance, (ii) reaction times and (iii) psychological factors (i.e., mood state, ratings of perceived exertion (RPE) and affective load) and on physiological parameters such as blood pressure, blood glucose, hematological parameters and other biochemical parameters.
An unacceptably high percentage of our nation's low-income, minority youth (< 18 years of age) are not regularly physically active. This contributes to extreme health disparities such as obesity rates nearly two-fold higher than those seen in white youth and greater risk for diabetes and related cardiometabolic disorders. The presence of quality youth physical activity opportunities (YPAO) enables and encourages physically active lifestyles. Unfortunately, quality YPAOs often are lacking in places where minority youth live, resulting in low activity levels and subsequent health issues that represent significant disparities in our society. The investigators' previous research found that small businesses (< 500 employees), which represent over 99% of all employers, are powerful resources for creating and improving YPAOs. In accordance with the Socioecological Model and established philanthropic principles, the investigators developed an alpha version of an intervention (alpha-i) for increasing small businesses' involvement with YPAOs. The investigators are now poised to create a beta version (beta-i) and conduct a pilot study of its impact on small business support for YPAOs and YPAO utilization by youth in low-income, minority neighborhoods. To meet this objective, the investigators will complete the following specific aims. Aim 1: Refine alpha-i components by completing focus groups with small business owners, YPAO providers, and parents/guardians of youth from low-income, predominantly minority neighborhoods. Results of the qualitative analysis will inform final tailoring of the intervention to create the beta-i which will be tested in Aim 2. Aim 2: Determine the effect of the beta-i on small business support for YPAOs in low-income, minority neighborhoods by conducting a plot cluster randomized-control trial with randomization at the neighborhood level. Intervention neighborhoods (n=10) will receive the beta-i while control neighborhoods (n=10) will be provided a standard practice intervention for a period of one year. The primary outcome for aim 2 will be the percentage of small businesses not supporting YPAOs at baseline that subsequently provide support for YPAOs at follow-up. The investigators also will consider the U.S. dollar equivalent of all types of support (monetary, goods/services and time) donated for YPAOs by small businesses. Aim 3: Examine the impact of the increased small business support for YPAOs on YPAO utilization by youth. The primary outcome will be the percent change in the number of youth participating in YPAOs from baseline and follow-up in the treatment and control neighborhoods. The proposed study is significant because it will provide evidence that an easily replicated approach can be used to increase small business support for YPAOs and that this support results in greater use of the YPAOs by youth. The investigators' next step will be to determine if YPAO changes resulting from increased small business support positively influence youth physical activity levels as measured by accelerometry. The investigators long-term goals are to create a nationally implementable practice for increasing support for YPAOs and strengthen the science of addressing health disparities in socially disadvantaged populations.
Neuropeptide Y (NPY) activates the sympathetic and vagal nervous systems through the Y1 and Y2 receptors. This double-blind placebo-controlled crossover study investigated the sympathovagal balance during three exercises on a cycloergometer in healthy volunteers treated with saxagliptin (DPP4 inhibitor).
Background: Complications impact physical and psychological recovery and are associated with financial cost. General physical function has not been studied in relation to the development of surgical complications in this cohort. Objective: Evaluate the physical function performance differences between those who develop complications and those who do not and determine their impact on recovery. Design: Observational Setting: The pre-operative assessment unit in the University Hospital Limerick. Patients: Forty-nine participants who were planned to undergo abdominal surgery were recruited & 43 completed the study. Main outcome measure: Demographics, physical function, lung function, surgical parameters, complications and recovery data was collected.
A mobile application will be tested in elderly men and women that is randomized to an application (blind-app) that registers physical activity or an application (feedback-app) where participants in addition set goals for physical activity and gets feedback from the application when these goals are achieved. Participants are randomized in permuted blocks of 10 to the blind-app or feedback-app. The primary outcome is increased physical activity. Secondary outcomes include, cardiovascular disease, diabetes, death, dementia, cancer, falls and fractures.
The primary purpose of the BOUNCE study is to assess the effectiveness of a four-week family-based healthy lifestyle summer program in reducing adiposity indicators in Hispanic and African American girls and boys (ages 9-14 years old).
The researchers will conduct a study for avoiding the metabolic syndrome in morbid obese patients. Thus, the aim of the present will be determine the effects of a resistance training programme (RT) in preventing or attenuating metabolic syndrome (MetS) in patients with morbid obesity. A second aim will be report the prevalence of non-responders in terms of improvements in MetS markers and other co-variables considered.
