Physical training is associated with many positive effects on body and mind. Especially for psychiatric patients in rehabilitation programs, sports therapy can be an essential part of the therapy plan. For psychiatric patients taking part in rehabilitation programs, motivation also plays an important part in the success of the training therapy. The aim of the study was to explore motivational as well as obstructive factors for physical activity in patients who take part in a psychiatric rehabilitation program. Insight into these factors was gathered from the patients past, present (time at rehabilitation center) and future. The theory section presents positive effects of physical exercise on the mind. Furthermore, qualitative research studies about motivational and obstructive factors for physical activity in psychiatric patients, the average population or other selected diseases are presented and discussed in this section of the paper. 9 patients (5 female, 4 male, age: 23 - 57 years) of the private clinic in St.Radegund, Graz, participated in the study. A qualitative study design was chosen, using semi-structured interviews. These interviews were transcribed and analyzed according to Mayring.
