The research activities of doctor Georges Jabbour involve three approaches 1) exercise and clinical physiology, 2) health promotion, and 3) individualize medicine.

Exercise and clinical physiology. Doctor Georges Jabbour is particularly interested in the sympatho-adrenal response to exercise and its impact on glucoregulation depending on factors related to the individual (ex. age, gender).  In addition, he studied the substrate utilization and metabolism during exercise in different diseased states (ex. type 1 and type 2 diabetes mellitus, cancer). Since 2012, he worked on projects dealing with the cardiac rehabilitation of organ transplant patients, women with breast neoplasia undergoing cardiotoxic chemotherapy; and in metabolic rehabilitation using neuromuscular electrical stimulation. Finally, since his undergraduate studies he was interested in identifying factors affecting performances and physical fitness indices in symptomatically individuals and athletes.

Health Promotion. The optimization of physical activity components (e. g. duration, frequency and intensity) is a major concern, especially considering the current lifestyle where so little time is devoted to physical activity. Doctor Georges Jabbour developed tools to promote physical activity practices among certain populations, especially those with high cardiovascular risk. Moreover, he is interested in identifying barriers that limit physical activity practices among specific populations, such as in children with type 1 diabetes.

Personalized medicine.  Since 2014, doctor Georges Jabbour studied the interaction between cancer and metabolic and cardiovascular diseases to determine the origin of this link and be so able to develop strategies of care more adapted to these patients.
