Study Details:

Length of study: 12 weeks total

Number of visits: 29 visits

Compensation: 200$


The study will be conducted at Texas Tech University in the Department of Kinesiology and Sport Management Building (Exercise and Thermal Integrative Physiology Laboratory). The main part of the study will require you to take omega 3 supplementations that we will provide you over 12 weeks. Other study procedures involve measuring your body temperature, heart rate, blood pressure, and perspiration. From week 6 to 12, you will visit the laboratory and rest in a hot water tub, lasting for 90 minutes each visit. At pre- and post-12 weeks you will have the following test done:


Pre-post Study Measures:

Mixed meal tolerance test that requires obtaining blood samples;

Vascular function test that measures small and large blood vessels health with a laser doppler and ultrasound;

Gut microbiome profile analysis which requires you to provide a stool sample.
