Research/Areas of Interest

Dr. Hayward is a Professor of Sport and Exercise Science and the Director of the University of Northern Colorado Cancer Rehabilitation Institute (). The focus of our work is to improve the quality of life for cancer survivors by providing clinical exercise-based rehabilitation programs, by educating those individuals who provide exercise-based rehabilitation services, and by conducting basic and applied research that advances our understanding of cancer rehabilitation. As the Director of Â鶹´«Ã½CRI, Dr. Hayward oversees all clinical, educational, and research activities of the Institute.

Patients enrolled in our cancer rehabilitation program serve as subjects in a wide array of research studies conducted by students in our undergraduate and graduate programs at the University of Northern Colorado. Clinical research conducted at Â鶹´«Ã½CRI utilizes a multidisciplinary approach which focuses primarily on: 1) the physiological adaptations that occur in cancer survivors during exercise training, 2) identifying the exercise intensity, duration, and modality that provides the greatest benefit for cancer survivors, 3) optimizing current techniques involved with exercise assessment and prescription in cancer survivors, and 4) understanding the effects of exercise on biomarkers of prognosis and survival in cancer survivors.

In order to further understand mechanisms that may explain the beneficial effects of exercise in cancer survivors, we utilize tumor-bearing rodent models to study the effects of exercise on various physiological systems with particular interests in the cardiovascular, muscular, and immune systems. Our facilities are equipped with modern wet laboratory equipment necessary to conduct an array of biological experiments including protein analyses, spectrophotometry, and flow cytometry. Our research focuses primarily on: 1) understanding mechanisms by which exercise attenuates chemotherapy-induced toxicities associated with standard cancer treatments such as anthracyclines, 2) the impact of cancer on cardiac, muscular, and immune function and how exercise can mitigate their deleterious effect, 3) how exercise can be used in the rehabilitation of cancer/cachexia-induced cardiac dysfunction, and 4) the interaction of cancer, chemotherapy, and exercise on clinical biomarkers of cancer prognosis and survival.
