In the study we are looking at how a bout of walking performed prior to prolonged sitting impacts arterial stiffness (non-invasive cardiovascular measure). This is important as increased arterial stiffness from prolonged sitting increases the risk for cardiovascular disease.

In this study, we want to learn about the effects of different kinds of force on the knee when walking on a treadmill. We will do this by looking at MRI images of knee cartilage in people with and without a history of ACL reconstruction.

In this study, we want to learn more about brain and body outcomes in young adults with and without a history of a concussion from a sport. By learning more about you and your lifestyle, it will help us to inform how we help and rehabilitate sport-related concussions in young adults.

In this study, we want to learn more about mental health stigma and resource utilization. We also want to learn how stigma affects attitdues towards mental health and mental health resources in collegiate athletes.

Individuals with a history of anterior cruciate ligament (ACL) injury and have had an ACL reconstruction (ACLR) are at a greater risk for developing osteoarthritis. The greater risk for developing osteoarthritis is likely caused by too little force or physical activity applied to the knee during weightbearing tasks such as walking. To reduce this decrease in forces during walking following an ACLR, we must first develop effective treatments that can train a person to walk in a way that reduces their risk of developing osteoarthritis. The purpose of this research study is to determine the feasibility and the initial effects of a 6-week training program designed to improve walking mechanics of individuals with an ACL reconstruction.

The purpose of this study to is assess changes in knee joint health before and after 8 weeks of physical activity participation in individuals with a history of anterior cruciate ligament reconstruction (ACLR) 6 months to 5 years ago.

In this study, we want to learn more about mental health stigma and mental health history. We also would like to learn about how these factors affect a person's willingness to participate in therapy.

There are 3 different non-invasive devices that are used to test how stiff your arteries are. We want to learn if these devices give us similar measurements. This will allow us to compare data across different devices, which will assist with future research.

The purpose of this study is to learn more about how people feel about staying safe during sports and concussion safety. This study will focus on participants who identify with underrepresented racial and ethnic backgrounds.

To understand the current health and well-being of athletes during the COVID-19 pandemic.
