Texas Tech University

Vascular Health Laboratory

The Vascular Health Laboratory (VHL) is located in the Department of Kinesiology & Sport Management and is directed by Dr. Arturo Figueroa. The primary research focus of the VHL is to investigate the relationships between vascular (macro and micro) function and muscular fitness or sarcopenia (mass, strength, and exercise capacity) in aging, hypertension, obesity, metabolic syndrome, and type 2 diabetes. The primary interventions used in the VHL are resistance exercise training and L-citrulline supplementation. Currently, there are collaborations with faculty focusing on vascular function, body composition, and dietary supplementations.

The VHL is equipped with an ultrasound device (GE LogiQ S7 R3) with an edge detection software, finometer MIDI, Complior Analyse, SphygmoCor Xcel, two Artinis MKII Near-Infrared Spectroscopy (NIRS) devices for measurements of endothelial function, blood flow, central (aortic and carotid) blood pressures and wave reflection, arterial stiffness, spontaneous cardiovagal baroreflex sensitivity, and hemodynamics. In addition, the VHL has collaborations that allow access to equipment to measure skin blood flow using microdyalisis (Moors and Perimed), body composition (DEXA GE Lunar Prodigy and BIA Seca mBCA 514), oxygen consumption, resting energy expenditure (indirect calorimetry, Moxus AEI) and ambulatory blood pressure (Mobil-O-Graph).

Arun Maharaj and Stephen Fischer have M.S. degrees in Exercise Science/Physiology from Florida Atlantic University and Kent State University, respectively. Both have extensive training in vascular physiology and are currently research assistants in the VHL. They will start the Ph.D. in Exercise Physiology in the Fall of 2018. Dr. Figueroa is looking for highly motivated graduate (M.S. and Ph.D.) students for the Fall 2018.  If interested, please contact Dr. Figueroa.
