The purpose of this project is to quantitatively and qualitatively examine the adherence and acceptability of the Oura Ring, and to examine the accuracy of the Oura Ring to measure physical activity. *This study is a collaboration with the UNC Sports Medicine Institute*

The purpose of this research study is to learn about people's reasons for drinking alcohol. We will do this by testing a new survey and asking people to tell us their opinions about the individual survey questions and the survey overall. The information we learn from this study will help us to improve survey questions so we can do a better job of asking people about their reasons for drinking alcohol in future studies.

This is a research study to find out which type of sedentary behavior, or sitting, is most strongly associated with cardiovascular disease (CVD) risk in endometrial cancer survivors. Additionally, we hope to better understand your perception of sedentary behavior and sedentary behavior reduction. The findings from this research study will be used to design a future sedentary behavior reduction intervention for endometrial cancer survivors. Participation in this study includes one assessment visit (during your regularly scheduled clinic visits) where we will measure your blood pressure and arterial stiffness using a blood-pressure like non-invasive device. Additionally, during this visit, you will answer questionnaires, complete a short physical function test (i.e., balance, walking, standing), and be instructed in how to use an accelerometer (movement tracking device worn on your upper thigh) paired with a smart-phone application that will ask you questions about your physical activities and sedentary behavior for 7-days following your

Interested in participating in future research studies? Whether you have had a previous ACL injury or not, you may be able to take part in several research study opportunities. This registry simply collects your contact information and then we will reach out if any study opportunities are available.

Are you interested in participating in orthopedic research? Are you otherwise healthy, with no previous history of lower extremity orthopedic injury? If so, you may be able to participate in a research study to determine the gait patterns of an otherwise healthy population.

Up to 30% of individuals who injure their anterior cruciate ligaments (ACL) suffer another ACL injury following reconstruction surgery. Improving function of the hamstrings muscles may reduce the risk of a second ACL injury. This study will determine if a novel rehabilitation tool (local muscle vibration) improves muscle function and landing characteristics (biomechanics) that are linked to ACL injury risk. Compensation is provided.

In this study, we want to learn more about female athletes' knowledge of nutritional concerns.

Have you had ACL reconstruction? You may be able to participate in a research study examining how brain function might change after surgery. Compensation provided.

The purpose of this study is to understand reporting behaviors of concussion symptoms among young adult athletes who have participated in organized sport when concussion occurs both inside and outside of sport. Focusing on reporting behaviors of non-SRCs will contribute to a more holistic view of concussion reporting behaviors which may enhance concussion reporting interventions to improve reporting patterns and athlete safety in the future.

This project is designed to get valuable feedback from physical therapists and patient groups for a video game product for knee rehabilitation. It is a sub study of an overall project that includes a clinical trial on the effect of the implementation of the video game. KneeBright is an EMG driven video game platform for rehabilitation for knee osteoarthritis. This custom program was developed to complement lower extremity strengthening.
