Purpose: This study looks at how college students' biomarkers (substances in the body) change with a short exercise. It compares active students with less active ones and also examines their mental health.

Study Process: Students will be split into two groups: active and sedentary. They will first have a pre-test where blood samples are taken to check markers like ammonia, insulin, cortisol, and a c-reactive protein. After a short wait, they will exercise on an elliptical machine for 12 minutes. Later, they will return to the lab for a post-test and answer a mental health questionnaire.

• Length: Short exercise session of 12 minutes.
• Visits Needed: One visit for exercise and tests.
• Eligibility: Healthy students aged 18-34 years.

Note: Students should be comfortable with blood draws and exercise, and they must have transportation to the lab. If you're allergic to nuts, you cannot participate.
