Dr. med. Valentin Z. Markser

Dr. med. Valentin Z. Markser studied medicine, philosophy, history and sociology. He runs his own practice for psychiatry, psychotherapy, psycho-somatic medicine and psychoanalysis in Cologne since 1988.

As a competitive athlete in handball he was German Champion, German cup winner and EHF cup winner. Thus, he focused occupationally on mental health in competitive sport for the last decades.


The Department of Sports psychiatry and psychotherapy of the DGPPN was founded due to his initiative. He is also member of the advisory board of the Robert-Enke foundation.

Professor Dr. med. Karl-Jürgen Bär

Prof. Bär is deputy director of the Clinic of Psychiatry and Psychotherapy belonging to the University Hospital Jena since 2010. Prior to that, he was deputy medical director of the LWL-Clinic in Bochum and assistant medical director at the University Hospital Jena.


He focuses scientifically on the influence of psychological disorders on the body. Thus, the altered perception of pain or the autonomic nervous system with regard to psychiatric diseases are his specialty. Due to that, it exists a close collaboration between the clinic and the Institute for Sports Medicine and Health Promotion (Prof. H. Gabriel) for roughly 10 years now. The impact of mental diseases on physical motivation is being investigated in the context of this collaboration.


Thereby the interest in mental diseases relating to competitive sports evolved and a respective outpatient clinic was founded. Prof. Bär is member of the Department of Sports psychiatry and psychotherapy of the DGPPN.
