About this research group
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.
Specifically, Dick examines the impact of physical activity on the quality and structure of arteries, and the role of hemodynamic forces (such as shear stress and pressure) on these adaptations. Recently, this work was summarized in an invited review for the leading journal Physiological Reviews (IF35.5)
In his work, Dick adopts state-of-the-art ultrasound-based techniques, such as flow-mediated dilation, pulse wave velocity, echocardiography and transcranial Doppler. To further improve their insight into the topics above, Dick also invests into the development of novel techniques to non-invasively measure vascular function (i.e. carotid artery reactivity) and cardiac function (i.e. deformation-area loops). This work recently resulted in the publication of the first papers on these novel techniques (J Hypert, JACC: CV Imaging, Ann Surg, J Physiol), which demonstrate enormous potential for future work and the potential of clinical and prognostic value.
In addition to examining ‘traditional’ modes of exercise training (e.g. endurance, strength, high-intensity interval), Dick's work has also focused on novel strategies to improve health. For example, he performed studies on the impact of prolonged sitting on cardio- and cerebrovascular systems and potential strategies to prevent these detrimental effects, including in clinical populations such as diabetes, cardiovascular disease and dementia (Exerc Sports Sci Rev, Diabetes Care). In addition, his lab has introduced the concept of exercise preconditioning (JAMA Cardiology) to explain how exercise protects against cardiovascular events. His lab was the first to explore the impact of (repeated) ischaemic on cardiovascular health (invited review in Exp Physiol).
- 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).
