Research Summary/Interests
The Cardiovascular Research and Rehabilitation Laboratory (CRRL) has a primary interest to investigate limitations in 1) human performance in healthy individuals and 2) exercise intolerance in those with cardiovascular and pulmonary disorders. In addition, we aim to develop novel treatment strategies to improve cardiorespiratory regulation during exercise.
The CRRL uses a multi-system approach as limitations to exercise are dependent on health and training status, exercise type and intensity and age of the individual. The interaction of systems is important for optimal exercise and activity performance. Our Laboratory uses several techniques to quantify heart, lung and skeletal muscle function (i.e. gas exchange, open-circuit acetylene wash-in for cardiac output, non-invasive blood flow measurements, and skeletal muscle strength and fatigue measurements) in healthy individuals and patients with cardiovascular and pulmonary diseases. Because of the disease progression in these patients, they develop skeletal muscle myopathies that limit exercise performance and can contribute to sensations of dyspnea, fatigue and ultimately exercise intolerance. We aim to delineate mechanisms of limitations to exercise and identify optimal treatment strategies to improve exercise and functional capacity and quality of life in clinical populations.
- Mechanisms of exercise intolerance in clinical populations including muscular dystrophy and heart failure
- The contribution of locomotor muscle afferents (group III and IV) to central drive and cardiorespiratory responses during exercise in both healthy adults and those with heart failure
- Autonomic regulation of blood pressure in post-menopausal women
- Mechanisms of increased cardiovascular disease risk in women who enter menopause premature or early
- Use of neuromodulation to reduce blood pressure in patients with hypertension and heart failure
