Aging is a process that is defined through a series of biopsychosocial processes. Many abilities of an individual develop throughout life, when they reach their peak, and after a certain time many abilities decline. Physical and cognitive changes occur during aging. Changes occur in physical appearance, in the cardiovascular and respiratory systems, in the digestive and urinary systems, in cognitive abilities, and especially in the skeletal system for movement. Physical activity is an important component in the model of active and healthy aging. Performing physical activity prevents the degenerative processes of aging, diseases of the locomotor system, the cardiovascular system, the onset of diabetes and even some types of tumors. It has a positive impact on preventing the development of sarcopenia, psychological health and inclusion of the elderly in the community and society. In addition to slowing down the aging process, it also acts as a protective health factor, has a favorable effect on a person's self-confidence, functional ability, cognitive abilities, satisfaction with life, sense of usefulness, belonging and connection with the community, and is often a source of relaxation and fun. In the process of aging, the functional assessment of an elderly person, the way of performing activities of daily life, and how physical activity affects their health is important. The implementation of physical activities should be appropriate and adapted to the individual, and should be an integral part of his lifestyle. It is essential to design an adequate program for elderly people in order to preserve or improve functional abilities. A physiotherapist can also provide his knowledge and expertise in the assessment and planned goals. Some of the recommended physical activities are: running, walking, skiing, hiking, gardening, tennis, cycling and many other forms of physical activity. In order to increase the physical condition of elderly people, the following can be used: aerobic exercises, strengthening exercises, balance exercises, coordination exercises, proprioception exercises and flexibility exercises. Sometimes it is difficult to find motivation in elderly people to engage in physical activity, therefore physiotherapists and other health professionals should encourage physically active and healthy lifestyles with their way of working.
