Vascular Aging Laboratory
Director: Joaquin U. Gonzales, Ph.D.
Location: Kinesiology & Sport Management Building, room 119
Laboratory Focus
Nearly half of U.S. adults have some form of cardiovascular disease. Many modifiable lifestyle factors have a strong impact on cardiovascular health. Our laboratory focuses on the multidirectional relation between sleep, physical activity, and vascular function in order to determine optimal behaviors to lower the risk for developing cardiovascular disease and promote healthy aging.
Funding
The Vascular Aging Laboratory at Texas Tech University has been active in human research since 2011. During this time, the laboratory has been funded by various funding sources.

Recent Research Findings
Does muscle microvessel reactivity associate with muscle perfusion during exercise? Our laboratory recently demonstrated that microvascular reactivity in the vastus lateralis muscle is correlated with oxygenation of the vastus lateralis muscle during moderate and high intensity exercise. This finding suggests that the capacity of muscle microvessels to dilate has the potential to inform about possible skeletal muscle microvascular limitations during exercise. This work is published in the journal Microvascular Research and can be viewed at https://doi.org/10.1016/j.mvr.2023.104569 .
