158 Clinical Trials for Various Conditions
This 12-week trial will test the efficacy of a multi-component, personalized text-message delivered behavior change technique (BCT) intervention to encourage habitual physical activity (defined as regular walking of 1,000 or more steps during a one-hour period on 7 consecutive days according to a personalized walking plan) among care providers of persons with AD/ADRD via the key mechanism of behavior change (MoBC) of automaticity. The main question it aims to answer whether a multi-component, personalized BCT intervention to increase a walking habit of 1,000 steps/day will lead to successful development of habitual walking among 60 percent of caregivers enrolled.
The disproportionately low physical activity (PA) in Latinas, particularly muscle-strengthening activities, and related chronic diseases (e.g., obesity, diabetes, cancer) signifies an urgent public health concern. To address the lack of interventions promoting muscle-strengthening activities exclusively for Latinas, the investigators are testing the preliminary efficacy of a culturally and linguistically relevant, web-based aerobic plus muscle-strengthening PA intervention in this at-risk population. The web-based intervention provides a more comprehensive and highly disseminable approach for reducing PA-related health disparities in Latinas.
The purpose of this study is to determine the efficacy of a new digital health tool that uses a phone and smartwatch to encourage physical activity and increase weekly amounts of Moderate to Vigorous Physical Activity (MVPA) over 12 months among adults compared to a digital health intervention that mimics a standard of care corporate wellness program.
In this study, the investigators are exploring how a mindfulness-based physical activity program can help improve exercise habits and overall health among 258 inactive Latina women aged 18 to 65. The study will be conducted entirely remotely over and 18 month period. During the first 6 months, all participants will receive an exercise program that has previously been tested by our research team. After 6 months, the investigators will check if participants are meeting the recommended exercise guidelines of at least 150 minutes/week of at least moderate intensity activity. Participants who meet the guidelines will continue with the successful exercise program for another 6 months. For participants who do not meet the guidelines (are exercising less than 150 minutes/week), they will receive one of two enhanced programs, which will be randomly assigned. One program offers additional physical activity support, and the other incorporates stress management through mindfulness techniques. For all participants, over 18 months, the investigators will track physical activity levels, stress, and heart health indicators.
The purpose of this pilot study is to examine the feasibility and acceptability of brief lifestyle intervention modules designed to promote healthy eating, activity, and weight control for pregnant and postpartum clients receiving care as part of evidence-based home visiting.
When muscles are not contracting, the local energy demand by muscle and use of specific fuels used to produce energy by oxidative metabolism are minimal. The time people spend sitting inactive (sedentary time) typically comprises more than half of the day. This sedentary behavior is associated with elevated risk of diabetes, cardiovascular diseases, some cancers, and multiple conditions leading to poor aging. From a progressive series of experiments, the driving goal is to develop a physiological method for sustaining contractile activity via oxidative metabolism over more time than is possible by traditional exercise (hours, not minutes per day). Developing a physiological method suitable of prolonged muscular activity for ordinary people (who are often unfit) requires gaining fundamental insights about muscle biology and biomechanics. This also entails a careful appreciation of the ability to isolate specific muscles in the leg during controlled movements, such as the soleus muscle during isolated plantarflexion. This includes quantifying specific biological processes that are directly responsive to elevated skeletal muscle recruitment. The investigators will focus on movement that is safe and practical for ordinary people to do given their high amount of daily sitting time. This includes developing methods to optimally raise muscle contractile activity, in a way that is not limited by fatigue, and is feasible throughout as many minutes of the day as possible safely. This also requires development of methodologies to quantify specific muscular activity, rather than generalized body movement. There is a need to learn how much people can increase muscle metabolism by physical activity that is perceived to them as being light effort. It is important to learn if this impacts systemic metabolic processes under experimental conditions over a short term time span in order to avoid confounding influences of changes in body weight or other factors.
The far-reaching negative health effects of the reduced physical activity (RPA) epidemic are often overlooked by the general population and health professionals. Short-term RPA induces cardiometabolic dysfunction, including impaired glucose control and vascular function, that may precede disease development. The impact of existing health status on RPA-induced cardiometabolic dysfunction and recovery of impaired glucose control following RPA is unexplored. Thus, the investigators' objectives are 1) to investigate the effect of existing health status (cardiorespiratory fitness and adiposity) on the recovery of impaired glucose control following a period of RPA and 2) to determine the role of vascular function as a mechanism of impaired glucose control. The investigators' final objective is to 3) expose undergraduate students to meritorious biomedical clinical research methods. The investigators have piloted the clinical research methods and analysis with undergraduate researcher associates and are well-prepared to complete this proposal. Preliminary data show that low cardiorespiratory fitness and/or high adiposity impair the recovery of glucose control following short-term RPA. Thus, the investigators aim to examine the interactive role of health status (cardiorespiratory fitness and adiposity) on the ability to recover impaired glucose control following short-term RPA. The investigators also seek to examine changes in vascular function as a mechanism of recovery of impaired glucose control following a return to normal PA. The investigators will recruit men and women with divergent health status (cardiorespiratory fitness and adiposity) to examine glucose control and vascular function during 7-d of normal PA, 7-d of RPA, and 7-d of resumption of normal RA. Continuous glucose monitoring and oral glucose tolerance tests will be performed to assess glucose control. Increases in vascular shear stress induced by passive leg movement and central arterial stiffness will be measured to assess vascular function.
The purpose of the study is to investigate the effect of different periods of physical inactivity on postprandial lipid metabolism in the morning after exercise by measuring plasma triglyceride levels and fat oxidation (burning). The study is a crossover intervention with all healthy participants performing three trials varying in length of physical inactive (4 hours, 8 hours, and 12 hours). All trials include a physical activity control phase (\>8,500 steps/24hr), a physical inactive phase, a moderate intensity cycling session, and a high-fat tolerance test.
Prolonged periods of reduced activity are associated with decreased vascular function and muscle atrophy. Physical inactivity due to a sedentary lifestyle or acute hospitalization is also associated with impaired recovery, hospital readmission, and increased mortality. Older adults are a particularly vulnerable population as functional (vascular and skeletal muscle mitochondrial dysfunction) and structural deficits (loss in muscle mass leading to a reduction in strength) are a consequence of the aging process. The combination of inactivity and aging poses an added health threat to these individuals by accelerating the negative impact on vascular and skeletal muscle function and dysfunction. The underlying factors leading to vascular and skeletal muscle dysfunction are unknown, but have been linked to increases in oxidative stress. Additionally, there is a lack of understanding of how vascular function is impacted by inactivity in humans and how these changes are related to skeletal muscle function. It is the goal of this study to investigate the mechanisms that contribute to disuse muscle atrophy and vascular dysfunction in order to diminish their negative impact, and preserve vascular and skeletal muscle function.
Physical inactivity is known to increase post meal blood sugar levels in young, active populations. However, how quickly this may occur in active, older adults is not clear. Further, the relationship between blood vessel health and blood sugar disturbances which occur to acute physical inactivity is not clear. It is unknown if impairments in blood vessel function precede increases in blood sugar levels that occurs with inactivity in an aging population. This study aims to determine if short term reductions in physical activity impair blood vessel health and blood glucose control to a greater extent in an aging population compared to a young population. The investigators hypothesize that 3 days of reduced physical activity will result in impaired blood vessel function and glycemic control in an aged population.
Mindful walking is a meditation practice that combines physical activity and mindfulness practice. The purpose of this study is to examine the effectiveness of mindfulness-based interventions provided for increasing physical activity among adults with low physical activity levels. A randomized controlled trial design will be utilized, with an intervention and waitlist control group (N = 160). Outcomes measured include physical activity, sleep quality, and functional fitness. Participants will receive a total of eight sessions of 60-minute mindful walking training within four weeks. The intervention group will receive the training in Weeks 1-4 and the control group will receive the training during Weeks 5-8. Each training group will consist of up to 20 individuals. Data will be collected at baseline, four weeks, and eight weeks to determine the efficacy of the intervention.
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.
Regular maternal physical activity leads to the delivery of lighter, leaner infants. Higher birth weights and childhood obesity are both strong predictors for adult obesity, suggesting that the impact of maternal physical activity on the future health of a child is substantial. However, the mechanisms underlying the relationships between maternal physical activity and improved infant outcomes are unclear. Thus, the purpose of this project is to measure two potential contributing factors: maternal fat metabolism and maternal oxidative stress profiles. The investigators believe that maternal physical activity leads to beneficial alterations in maternal fat metabolism and oxidative stress profiles. Further, the investigators believe that both maternal fat metabolism and oxidative stress levels are related to infant outcomes such as obesity and insulin resistance. Therefore, exercise will improve maternal metabolic factors that can lead to improvements in infant outcomes. The investigators will compare these factors between obese inactive pregnant women and obese active pregnant women. This study design will allow us not only to determine the effect of physical activity on maternal and neonatal pregnancy outcomes, but also to establish whether obesity or physical inactivity should be a primary area of focus when prescribing pregnancy interventions in clinical practice.
The purpose of this study is to determine how a decline in physical activity acutely leads to a decrease in insulin sensitivity in skeletal muscle. The hypothesis is that the loss of insulin sensitivity following physical inactivity is caused by a rapid reduction in skeletal muscle mitochondrial oxidative capacity.
The proposed research will examine the role of physical activity (PA) on altering sleep quality (SQ) while systematically examining novel mechanisms that may drive changes in SQ. Specifically, the study will examine how a 2 week reduction in PA alters sleep quality in young, healthy individuals. Additionally, during this reduction in PA, the study will examine changes in inflammation, oxidative stress, and sympathetic activity to identify potential mechanisms for alterations in sleep quality.
Physical inactivity is pervasive and prevalent in the United States, particularly among women of low socioeconomic position, and women with children. Structural and social barriers make active leisure time a rare commodity creating a pressing health issue because physical inactivity increases the risk of chronic diseases and poor health. The broad objective of this study is to test the effectiveness of Free Time for Wellness (FT4W), an innovative multilevel physical activity intervention to increase physical activity among low-resourced mothers.
This early-phase trial will test intervention strategies to influence affective mechanisms underlying physical activity and determine whether changes in those mechanisms result in change in physical activity behavior among inactive adults who are overweight or obese.

This research study is designed to better understand how a virtual reality (VR) exercise application may influence overall physical activity and well-being. VR games can make exercise more enjoyable and interactive, which has been shown to increase engagement in physical activity. Adult participants will do a progressive exercise program and report on overall physical activity, health, and psychological wellbeing. The intervention is expected to have a positive impact on these lifestyle factors.
This is a small pilot intervention trial in which we will collect preliminary data to demonstrate the feasibility of an intervention study.
This trial is designed to develop and test the efficacy of cognitive training strategies to improve self-regulatory capacities for middle-aged adults to adopt and sustain a physically active lifestyle. The main questions it aims to answer are: * Can cognitive training designed to improve cognitive control improve physical activity adherence? * What are the psychological, physiological, cognitive, and sociodemographic factors that affect the impact of cognitive control on physical activity adherence? Participants will * Complete a 6-week home-based, computerized cognitive training program * Complete a 6-week home-based, aerobic exercise training program with supervision of a health coach and trainer * Complete a 6-week home-based, aerobic exercise training program prescribed by a health coach and trainer * Visit the laboratory before and after cognitive training, and before and after physical training, to complete assessments of cognition and aerobic fitness
The effects of exercise on prevention and improved control of chronic diseases, reduced mortality, and improved quality of life are well established. Exercise has been shown to prevent heart disease, stroke, type 2 diabetes, depression, and certain types of cancers. In addition to prevention, physical activity is included in the standard or care for many chronic diseases and used in treatment. For example, the American Diabetes Association has identified positive health behaviors like physical activity as foundational in the treatment and management of disease and improving overall quality of life. The Ohio State University Wexner Medical Center Exercise is Medicine Program (EIM) is a physician referral program that aims to increase physical activity to prevent and reduce complications from chronic disease. The integration of technology among a 65+ population of EIM participants provides a novel approach to improving individual's health. Thus, our study aims to provide EIM participants aged 65+ with smartwatches in the hopes of increasing their overall physical activity levels.
The goal of this quasi-experimental study is to assess and compare the effectiveness of text message interventions and a competition-based intervention and evaluate participants' acceptability and experiences in university students. The main questions it aims to answer are: 1. What are the effects of text message interventions and competition-based interventions on university students' physical activity levels, self-efficacy, self-regulation, social support, incentive motivation, and mental well-being? 2. What are participants' perceptions regarding their experience with and acceptability of text message interventions and competition-based interventions? Participants will 1. participate in a fitness competition 2. participate in a fitness competition and receive text messages 3. enroll in control group
The eMOTION Study is a two-part ORBIT model phase 1 trial. The first part, called the Formative Study, will assess acceptability and feasibility of a novel physical activity intervention in adults at increased risk for cancer due to overweight or obesity.
This study plans to learn more about the feasibility and acceptability of integrating the Move physical activity support program within an existing lifestyle intervention program.
Research has demonstrated the positive effects of chronic exercise on cognitive functioning and performance of Activities of Daily Living (ADLs). However, minimal research exists regarding the effects of acute exercise. To address this gap in the literature, the present study investigated the effect of an acute bout of exercise on executive functions, balance, and ADLs among healthy older adults. Based on the current literature, we expected participants in the exercise group to perform better on executive function tasks and ADLs compared to participants in the control group.
This project was a 12-week aerobic and resistance training intervention that included participants meeting at a pre-determined location from 1-2 times per week for 12 weeks. Aerobic activity was walking. Resistance training included traditional and non-traditional implements.
This pilot study will test the feasibility of pairing a social network-based approach with a 6-week Occupational Therapist (OT)-led intervention administered remotely (via Zoom) to increase physical function and activity among residents of a HUD subsidized independent-living senior housing community. The intervention is called Tele-Video to Improve Daily Activity (T-VIDA) and will be administered with two cohorts of residents in a single community. The study has two main goals: 1) To determine if an OT-led program administered remotely over the internet using Zoom is useful in helping residents increase their physical activity; and 2) to determine if involving respected members of the community in the program as Advisory Committee members has an impact on how much other residents participate in program activities and engage in behaviors discussed. The OT intervention will be comprised of a combination of adapted components from multiple evidence-based interventions including individual meetings with an OT and OT-led group sessions. To evaluate the intervention pre- and post-program interviews will be conducted with participants over the phone, and activity monitoring will be conducted after both the pre- and post-program interviews for 7-days using an activity monitoring device. The following hypotheses will be tested: 1) at least 75% (3 of 4) of identified residents will accept the invitation to serve on the Advisory Committee; 2) Advisory Committee Members will attend at least 2 of 3 committee meetings; 3) Participants will on average participate in at least 70% (7 of 10) of intervention activities; 4) Residents knowing one or more committee members at baseline will participate in more intervention activities compared to those who do not; and 5) The influence of knowing a committee member on participation will be greater among residents reporting more pain at baseline compared to those reporting less pain.
The current study will be a randomized controlled pilot study conducted in the Midwest. Participants will be randomly assigned to a behavioral intervention or a wait-list control group, each lasting six weeks. The intervention group will first have an in-person meeting at the beginning of the intervention to discuss the study, go over movements, and discuss Zoom and WhatsApp instructions. The behavioral intervention will consist of three home-based workouts per week sent digitally and Zoom session per week that will have an exercise session and a group counseling session. Additionally, each week participants will be sent a motivational prompt via WhatsApp and will be encouraged to connect with each other about physical activity motivation, barriers, and facilitators. Acceptability, physical activity and psychosocial variables of interest will be measured via accelerometer data (via Actigraph GT3X) and self-report at baseline and six weeks (post-intervention). Focus groups will be conducted for all participants at the conclusion of the study to further assess acceptability, feasibility, and efficacy of the program.
The purpose of this 4-week randomized study is to evaluate the effect of personalized plans plus an email campaign, with and without email-based coaching (eCoaching), on engagement in a new weekday outdoor walking (WOW) routine and average daily step count. Approximately 150 participants will be recruited via paid ads on Facebook and Instagram. Participants will be randomized to a control group, an intervention group without eCoaching, and an intervention group with eCoaching. The control group will be told that they can work a WOW routine on their own, with the opportunity to take part in the intervention after completing the 4-week follow-up assessment. Both intervention groups will complete an activity that will guide the creation of habit plan (e.g., When I finish eating lunch at work, then I will put on my walking shoes and go outside) and receive a 2-week long personalized email campaign. The primary outcome of interest is change in average daily step count from the month prior to the month after baseline assessment, as compared across the three groups. It is hypothesized that the intervention groups will result in an increase in daily step count, as compared to the control group. Secondary outcomes include habit strength at one-month follow-up and change in self-reported sleep quality and self-efficacy from baseline to follow-up.
