Filter by:Barriers to physical activity (PA) among African Americans (AAs) have been extensively studied, yet there is a paucity of innovative PA interventions designed to address them. In recent years, many studies have used the internet to promote PA in many settings, including the home environment, but only a few studies have recruited AAs. Without innovative and culturally relevant interventions, AAs will continue reporting extremely low levels of PA and disparate cardiovascular health outcomes. In prior work, the investigators sought the input of AA focus groups to inform the development of a technology-based Physical Activity for The Heart (PATH) intervention that leverages openly accessible platforms, such as YouTube, to promote PA in any setting. The investigators designed PATH as a culturally salient action-oriented intervention that can be accessed in any setting to promote PA among inactive AAs. In this application, the investigators propose to examine whether PATH is a feasible strategy for promoting PA among inactive AAs. In Aim 1 the investigators will conduct a randomized clinical trial that will include 30 inactive AAs to assess the feasibility and acceptability of the PATH intervention. In Aim 2 the investigators will examine the trend in PA and cardiovascular disease risk change from baseline to post-intervention. This approach is innovative because it leverages openly accessible technologies to provide a wide variety of free, enjoyable and action-oriented workout videos that match AAs preferences. This contribution will be significant because PATH could offer a novel, low-cost, and scalable strategy for promoting PA among individuals facing socio-environmental barriers to PA.
Implementation intentions support people to turn intentions into action, and "Volitional Help-Sheets" are a tool which helps people to form implementation intentions. The study will recruit participants from secondary and tertiary mental health services. The participants will be randomised to one of two groups. Participants in Group 1, the control group, will receive the Volitional Help-Sheet (psychoeducational self-help sheet) but not form implementation intentions. Participants in Group 2, the experimental condition, will use the Volitional Help-Sheet to form implementation intentions. Participants will then complete an acceptability and feasibility measure. At follow up, participants will repeat baseline measures. The feasibility and acceptability of using a Volitional Help-Sheet to form implementation intentions to help people using secondary and tertiary care mental health services to reduce sedentary behaviour will be evaluated.
Cardiovascular disease is the second major cause of death for women in Israel and the leading cause of death among women worldwide. Women have higher mortality rates after a coronary or cerebrovascular event compared to men, and receive less attention for prevention and treatment of heart disease. The risk factors for heart disease among women in Israel are high: 53% of women in the State of Israel are overweight or obese and 48% of women do not exercise. Increasing physical activity can lower the risk of developing cardiovascular disease in women. The literature suggests that even minor changes in behavior can reduce the morbidity, mortality and costs to the health care system. Pedometers have proven to be an effective tool for increasing physical activity, and have the potential to create change in health habits. The pedometer measures steps and is a simple measure that gives an estimate of the extent of exercise in terms of steps. The device is simple and user-friendly and serves as an indicator of movement as a result of health choices. The literature shows that when pedometers are integrated into a support program, they provide an incentive to increase physical activity. Supporting software includes, among other things - choosing personal goals, close tracking, and self-tracking and re balancing systems. "Implementation intention" is a strategy in the form of an "if-then plan" that can increase the likelihood of attaining one's goals. It is different than specifying a goal intentions as it specifies the when, where and how portions of goal-directed behavior. This study seeks to compare the increase in steps in participants randomly assigned in a 2:2:1 allocation to a goal-setting pedometer intervention, a goal-setting plus implementation intentions pedometer intervention vs pedometer only.
Investigating the effects of interrupting various lengths of prolonged sitting with bike sprints on post prandial lipemia the next day. We will conduct three trials, one control, one with two-hour sitting intervals (total of 4 bouts of bike sprints) and one with 6-hour sitting intervals I total of two bouts of bike sprints). A milkshake high fat tolerance test will be conducted the next day and whole body fat oxidation as well as triglyceride area under the curve will be measured every hour for the duration of the 6-hour test.
Regular physical activity should be the essence of treatment in patients with cardiovascular risk factors. Unfortunately, these interventions are usually insufficiently promoted and therefore have only limited efficacy. The aim of the study was to determine the benefits of nurse led intervention to promote physical activity in sedentary older adults with cardio-vascular risk factors in the outpatient setting. Eligible patients are randomized in a 1:1 fashion to receive nurse led tutorial on life-style modification including pedometer hand-out with a daily goal of at least 7000 steps and supporting phone calls (study group) or without a goal or calls (control group). The primary end-point of the study is change in body weight. Secondary end-points include changes in resting heart rate, systolic and diastolic blood pressure, total cholesterol and fasting glucose and clinical outcomes at 3 months follow-up.
In this study, video-based training, aerobic training and both training will be applied to individuals with internet gaming disorder. Addiction levels and functional performance will be evaluated before and after treatment.
Prolonged sitting may pose a public health risk through its effects on the cardiovascular system, and may lead to impaired whole-body cardiovascular health, which includes both vascular and cerebrovascular function. These effects may interact with other environmental variables, such as stress. However, no study has investigated the combined effect of a mental stressor and prolonged sitting on vascular and cerebrovascular function. The combined effect of prolonged sitting and mental stress may lead to an exacerbated effect on vascular, cerebrovascular, and executive function. The investigators hypothesize that mental stress with the addition of prolonged sitting [PS] will result in a greater increase in peripheral, central and cerebral arterial stiffness and elicit a decrease in cerebral perfusion, total blood flow to the brain, middle cerebral artery velocity and executive function, compared to mental stress without prolonged sitting [CON]. The findings from this study may result in a public health message regarding sedentary behavior and stress, and will help elucidate the mechanisms behind acute vascular, cerebrovascular, and cognitive dysfunction during prolonged sitting.
The investigators hypothesize that cycling for 1 hour of exercise at 65% peak oxygen consumption (VO2peak) after sitting >13 hr/day (SIT+EX) will not be different in postprandial plasma insulin responses compared to the control of only sitting (SIT). Furthermore, the investigators hypothesize that the SIT and SIT+EX groups will have a less favorble insulin response compared to the physically active group after performing the same 1-hour exercise bout (ACTIVE+EX).
Physical inactivity is a significant predictor of major non-communicable diseases such as type 2 diabetes (7%), cardiovascular disease (6%), musculoskeletal disorders and some cancers, and has been proposed to be the 4th leading cause of death worldwide. Reduced physical activity leads to an impaired function of the hormone insulin and increased adiposity. Thus, the elimination of physical inactivity would remove between 6% and 10% of the major non-communicable diseases and increase life expectancy. The aim of the study is to investigate the effects of a short-term (2-day) period of reduced physical activity, with and without a proportional decrease in energy intake, on the action of insulin to regulate blood sugar fluctuations, appetite, and cardiovascular parameters (heart rate, cardiac output, stroke volume, blood flow, arterial blood pressure, peripheral vascular resistance) in response to food ingestion.
The recent literature has highlighting the importance of the time of inactivity and the level of physical activity (PA) as predictors of metabolic cardio risks. Now, sedentary lifestyles are well recognized as one of the causes of mortality. As with physical activity, a dose-response relationship appears to exist: mortality would increase with time spent in sedentary behaviors. However, this relationship would not be linear: the more the daily sitting time increases, the more the consequences on mortality are important. It is now well demonstrated that time spent in sedentary adult behaviour finds primarily its origin in the work, characterized by prolonged and uninterrupted periods of sitting. Many strategies have been settled to break the prolonged sitting time. The most promising one seem to be the use of active workstations (treadmill, cycling, stepping) because they reduce sedentary time at work and increase physical activity with positive effects on the global health. If active workstations have demonstrated their effectiveness with overweight or obese people by increasing daily energy expenditure, their interest in prevention in normal weight people is less known. In addition, the long-term effectiveness of a program of reactivation by active workstation on biological parameters, quantitative and qualitative time of sedentary behaviour (duration, number of breaks) and physical fitness was not assessed. The main objective of this project is to study the effects of the use of a cycling workstation for 60 minutes per day (30 minutes twice a day) for 3 months among professionals with an office-sitting desk on overall quantity of physical activity time (work and non-work) and sedentary time.
