This study is examining the impact of testing order on maximal strength and oxygen uptake assessment performance. We aim to determine if a testing order for these variables exists that maximizes results for use in future research interventions and athletic combines.

We are doing this study to learn if exercise impacts the effect of social tasks on energy use and heart function. Since exercise may impact metabolic factors such as energy use as well as the impact of social situations on cardiovascular disease, we want to see how exercise impacts the effect of social situations on energy and metabolism, and whether this may affect your heart health.

The Lower Extremity Assessment Protocol (LEAP) is a program to prevent reinjury and promote long-term health by characterizing muscle function, evaluating movement performance, and monitoring patient-reported outcomes (e.g., pain). The purpose of this study is to learn more about the outcomes following orthopaedic surgery after a lower limb injury. *This study is a collaboration with the UNC Sports Medicine Institute*

We now know there is a link between sedentary behavior (e.g., sitting) and heart disease. However, we do not yet fully understand if sedentary behavior performed in different settings and situations (e.g., sitting alone watching television vs sitting with friends at a bar) differentially impacts heart disease risk. This is what this study aims to find out.

Many young athletes who tear their ACL have trouble getting back to sport or suffer a second ACL injury once they do. We aim to improve athletes' ability to get back to sport safely. We want to make the activities athletes perform in rehabilitation more closely match the demands of what they do once they return to their sport. We also aim to develop low-cost ways to measure how the knee is moving during those activities. *This study is a collaboration with the UNC Sports Medicine Institute*

The purpose of this study is to investigate the reliability of multiple body composition techniques in a multi-ethnic population.

We are looking for young adults 18 to 30 years old who have had a concussion in the past 5 years to take part in a six-week study to learn if mindfulness can help outcomes after a concussion.

Interested in participating in future research studies? Whether you have had a previous concussion(s) 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.

In this study, we want to learn more about young adults with a history of concussion and their relationship with stress and mindfulness. This will help us to create concussion prevention and rehab plans to improve recovery.

Do you sit too much at work or home? There is strong evidence for an association between sitting and cardiovascular diseases such as coronary heart disease and stroke. In this study, we want to identify strategies to break up sitting for long periods of time. Compensation will be provided.
