1. INTRODUCTION
Peripheral arterial circulation diseases can be divided into
two groups: occlusive and non-occlusive diseases, i.e. functional
disorders. Ageing is a well known risk factor for cardiovascular
diseases and as such it is assessed as the most frequent
cause of death in the elderly (1). Physical activity plays
an important role in treatment of patients with peripheral arterial
disease. Regular training increases functional ability;
it has a positive influence on cardiovascular risk factors and
improves quality of life (2). Physical training in peripheral arterial
disease (Claudicatio intermittens), especially supervised
walking, is very efficient in treatment and secondary prevention
of this disease (3). The entire research has been conducted
in Clinic for vascular disease, Clinical Center of Sarajevo
University (CCUS). Research was controlled in two defined
comparative groups.
