Exercise Clinical Trials

The purpose of this study is to test whether a natural product supplement can potentiate the increase in collagen synthesis following the ingestion of collagen protein. The investigators have developed a model of natural (GRAS certified) products that stimulate collagen synthesis, in vitro. The investigators will determine whether the natural product supplement can potentiate the collagen synthetic response to the ingestion of collagen protein. Basal and fed serum will be isolated and these samples will be used to treat human engineered ligaments. Read Less

This randomized controlled crossover trial of 36 pregnant individuals with gestational diabetes (GDM) or gestational glucose intolerance (GGI) will: Determine the effects of physical activity (PA) timing, specifically 30 minutes of moderate intensity walking or stepping in the morning (between 5am-9am, within 30-40 minutes of starting breakfast), versus late afternoon/evening (between 4pm-8pm, within 30-40 minutes of dinner) on glucose across the 24-hour cycle. Explore the potential effects of the timing of PA on sleep and mood state. Read Less

Today's children have become increasingly inactive and unfit, with >50% of children not meeting the recommended 60 min of moderate-to-vigorous physical activity. Previous research has suggested that acute aerobic exercise of moderate intensity was associated with improved cognition manifested by improved performance and increased P3 amplitude, a neuroelectric indicator that reflects the amount of attentional allocation, in tasks requiring cognitive control. While minimal evidence exists to support potential mechanisms underlying the transient effects of exercise on brain and cognition, research suggests that phasic changes in the locus coeruleus-norepinephrine (LC-NE) (as measured by salivary alpha amylase (sAA)) system are a potential mechanism for explaining the acute effect of exercise on brain and cognition. Accordingly, the aim of this study is to examine the mechanisms linking acute aerobic exercise to improved cognitive control as well as the underlying neuroelectrical activities in children, using electroencephalography (EEG) and event-related potentials (ERPs). We hope to gain a better understanding of the role of acute exercise and cognitive and brain health. The results from this study will help identify mechanisms linking acute exercise to enhanced cognitive performance in children. Our hypothesis is that exercise-induced phasic increases in sympathetic nervous system activity will mediate the effect of a single bout of exercise on brain function, cognition, and standardized achievement test performance.

Multiple case study trial examining the adoption, implementation, and reach of eligible patients visiting participating Prisma Health primary care clinics and receiving a referral to a 12-week evidence-informed physical activity (PA) program hosted at local community PA facilities. Read Less

The purpose of this study is to determine the feasibility and effects of an adapted Exercising Together, a partnered resistance training program, on the physical and mental health of prostate cancer survivors and their informal caregiver. The Exercising Together program is designed to promote teamwork during supervised group exercise classes delivered remotely through videoconferencing software. The intervention period will be 3-months with a 3-month follow-up. Read Less

Low physical activity levels contribute to African American men experiencing health disparities across a number of chronic diseases. Studies have been effective in increasing physical activity levels in African American men; but few have targeted maintenance of behavior change and none have utilized emerging technologies. The purpose of the current study is to further develop a mobile phone application for African American men that will help them initiate and maintain their physical activity levels. Read Less

Engaging in regular physical activity during midlife is a key lifestyle behavior associated with reduced risk for Alzheimer's disease and related dementias (AD/ADRD). Yet nearly half of midlife adults (48%) do not meet national physical activity guidelines. The purpose of this mechanistic trial is to identify effective goal setting techniques to enhance psychosocial processes of self-regulation for the successful promotion of PA and adherence to national PA guidelines among midlife adults, with the long-term goal of reducing AD/ADRD risk Read Less

A 12 weeks technology enhanced home exercise (TEHE) program using mobile technologies that provide immediate feedback and send reminder messages to improve exercise motivation is developed. Investigators combine this TEHE program with techniques including auricular point pressure (APA) and brief mindfulness body scan (MBI). This study will examine the feasibility of the TEHE program and combined programs, and ascertain the effect of TEHE program alone, the combined programs on fatigue and biological markers among cancer survivors. Main Research Variable(s): The independent variables are the 12-week program of TEHE alone, APA alone, combined APA and TEHE (TEHEplus) and combined MBI and TEHE (TEHE-MBI). Outcome variables are fatigue, physical activity, contributing factors of fatigue and biomarkers. Design: Repeated measures randomized controlled trial. Setting: Participants will be recruited through the Comprehensive Cancer Center, Johns Hopkins University. Sample: Participants diagnosed with non-metastatic solid tumor cancer; who had completed all primary cancer treatment (surgery, chemotherapy, and radiation therapy )within at least 3 months OR non-metastatic prostate cancer completed all primary cancer treatment and have hormone therapy for at least 6 month, OR participants diagnosed with solid tumor cancer; who are receiving immunotherapy for at least 3 months before enrollment, aged 21 years or older, experiencing fatigue in the past 7 days on average of ≥ 3/10, able to participate in a moderate-intensity exercise training program, self-report ability to complete the 6 min walk test with a perceived exertion of 3 or below, and can communicate in English. Methods: Participants who meet the inclusion criteria will be randomly assigned to the TEHE only, APA only or TEHEplus or TEHE-MBI or control group. All exercise groups (TEHE) will be offered a 12-week exercise program through an online communication. In additional to the TEHE, the TEHEplus group will receive an instruction on how to apply the pressure on the ear points through online meeting/communication. The TEHE-MBI group will perform 5 min mindfulness body scan daily. The control (usual care) group will report participant's fatigue level daily. At the end of week 12, participants will answer open-ended questions about participant's opinions on the programs. Fatigue will be assessed and blood will be drawn before and after the program.

This project evaluates the feasibility of using custom wearable technology and associated procedures to increase activity of the more-involved upper extremity during the earliest stages of recovery from stroke by increasing the amount of therapeutic exercise during idle-time. The proposed research is relevant to public health because it takes steps to mitigate a significant problem in physical rehabilitation using low-cost technology to motivate and monitor idle-time exercise without adding significantly to clinician workloads. The project aligns with the NICHD / NCMRR Research Plan on Rehabilitation by exploiting a mobile health (mHealth) and sensor-based approach to promote health and wellness through participant-engaged, data-driven, individualized care.
