Cardiovascular physiology and physical (in)activity
This research group focuses on the field of cardiovascular physiology and physical (in)activity. The work strongly focuses on understanding the impact of exercise training and physical activity on reducing the risk of developing cardiovascular and metabolic diseases.read more
- Understanding of the impact of hemodynamic stimuli (such as shear rate) in mediating vascular adaptation in response to exercise training and physical activity.
- Examine how improvements in vascular function-structure contribute to the cardioprotective effects of regular exercise training.
- Assess the role of hemodynamic stimuli (specifically blood flow or shear rate) in the process of atherosclerosis in central and peripheral arteries.
- Examine the role of physical inactivity or sedentary behaviour (i.e. too much sitting) in the development of non-communicable diseases, such as cardiovascular disease and metabolic disorders, but also other disease states characterized by physical inactivity (e.g. dementia, Parkinson’s Disease).
- Development of novel ultrasound-based techniques to examine cardiac (i.e. strain-volume loops) or vascular function (i.e. carotid artery reactivity) to improve physiological understanding of disease processes and predict future events.
- Explore the impact of exercise preconditioning in protecting against the severity of cardiovascular events, and identify potential factors interfering with these effects.
- Understand the potential clinical impact of (repeated) ischaemic preconditioning in improving cerebral and peripheral vascular health in healthy and diseased populations.
- Repeated elevations in shear stress represents a key stimulus in mediating adaptations in vascular function and structure, which subsequently contribute to cardioprotective effects of regular exercise training and physical activity (Physiol Rev 2017).
- Exercise preconditioning refers to the phenomenon that exercise mediates immediate cardioprotective effects immediate after a single bout of exercise (JAMA Cardiol 2018).
- Development of the carotid artery reactivity test as a novel, simple, non-invasive tool to examine carotid artery vascular function. My lab reported close relation with coronary artery vascular function, relation to traditional cardiovascular risk factors, and found independent prognostic value for future cerebro-/cardiovascular events (J Hypert 2017, Annals of Surg 2018).
- The novel strain-volume loop of the left (J Physiol 2017) and right ventricle (JACC: CV Imaging 2017) have strong clinical potential to improve mechanistic insight into cardiac disease and may improve classification of patients groups.
- An increase in sedentary behaviour relates to weight gain after the start of insulin therapy in type 2 diabetes patients (Diabetes Care 2017).
- Exercise training has a larger impact on visceral fat compared to dietary interventions, despite demonstrating smaller effect sizes on body weight (Obes Rev 2017).
- Repeated exposure to ischaemic preconditioning leads to local and systemic improvements of conduit, resistance and (skin) microvessels (Exp Physiol 2016).
