Exercise clinical trials at University of California Health
7 in progress, 5 open to eligible people
open to eligible people ages 18-35
The proposed study aims to shed light on the function/importance/relevance of exercise-induced changes in exosomes to connective tissues. Exosomes are known to increase robustly in response to exercise. We have previously shown that serum isolated from subjects after they lift heavy weights increases human engineered ligament collagen content and mechanics more than serum from before they lift weight. Further, we showed that exercise-induced changes in hormones could not explain the change in ligament structure or function. These data indicate that there is a significant gap in our understanding of muscle-connective tissue crosstalk. To address this gap, the current proposal seeks to: i) isolate and sequence exosomal RNA (long non-coding, miR, and mRNA) and ii) determine whether exosomes isolated from serum after exercise increase engineered ligament mechanics and collagen content.

The goal of the Molecular Transducers of Physical Activity Consortium (MoTrPAC) is to assess molecular changes that occur in response to physical activity (PA). To achieve this aim, studies will be conducted in adults and separately in children and adolescents. The UC Irvine MoTrPAC Pediatric Clinical Center oversees two interrelated study phases in children and adolescents: 1. A cross-sectional phase in which molecular transducers (obtained from blood sampling) are measured in response to an acute exercise challenge (n = 320); 2. An intervention phase is conducted as a mechanistic randomized controlled trial (RCT). Participants are recruited from the cross-sectional study phase and randomized to endurance exercise (EE) training (n = 120) or no exercise Control (n = 50) for a period of approximately 12 weeks.

This study will conduct a randomized trial to evaluate the efficacy of a theory-based, individually tailored, multi-technology intervention on increasing physical activity in Latina adolescents, compared to a control group receiving only a physical activity tracker (a Fitbit). The investigators will recruit adolescent (age 13-18) Latinas (N=200) who are currently underactive to participate in the 12-month trial. Those randomized to the Intervention arm will receive a one-on-one counseling session and access to an individually tailored multi-media website. Key intervention components will be reinforced through text messaging to aid goal setting, a physical activity tracker (Fitbit) to set goals, track and log activity, and access to a study Instagram account to reinforce exposure to web content. The primary outcome will be increases in moderate-to-vigorous activity between baseline and 6 months. Secondary outcomes will include changes in activity at 12 months, potential mediators of the intervention, costs of delivering the intervention, behavior change trajectories from continuous data from Fitbits, potential moderators, and changes in physiological and psychological variables.
open to eligible females ages 13-17
The study will examine the mechanisms linking race, stress and biobehavioral factors to energy balance and obesity in both natural and controlled environments in African-American and Caucasian adolescent females. A Hispanic/Latina cohort has recently been added with permission for the sponsor.

open to eligible people ages 18 years and up
The researchers are evaluating longitudinal changes in multiple health, economic, and environmental outcomes over a 3-year COVID recovery period and in the context of a new light rail transit (LRT) line, called the Mid-Coast Trolley, among 465 UC San Diego (UCSD) staff. The primary aim is to evaluate change in objectively measured total and moderate to vigorous physical activity (MVPA), travel mode, and vehicle miles traveled (VMT).
Sorry, in progress, not accepting new patients
The main aim of the "Diabetes and Mental Health Adaptive Notification Tracking and Evaluation" trial (DIAMANTE) is to test a smartphone intervention that generates adaptive messaging, learning from daily patient data to personalize the timing and type of text-messages. We will compare the adaptive content to 1. a static messaging intervention with health management and educational messages and 2. a control condition that receives a weekly mood message. The primary outcomes for this aim will be improvements in physical activity at 6-month follow-up defined by daily step counts.
Investigating KardioPAC Mobile App to Improve Physical Fitness Among Cardiac Rehabilitation Patients
Sorry, accepting new patients by invitation only
The purpose of this study is to sustain regular physical activity, improve health-related quality of life, improve resting blood pressure, improve anthropometrics, and improve adherence to prescribed cardiac rehabilitation sessions among individuals referred for cardiac rehabilitation (CR). Numerous studies show that CR improves clinical outcomes in cardiovascular disease (CVD). Exercise as a reliable adjunctive intervention, however, remains limited due to poor short- and long-term adherence. This proposed study will examine the effectiveness of the Kura Care KardioPac digital application plus CR to significantly sustain exercise adherence among CR patients, as compared to standard of care alone.
