Physical activity is one of the most important element of a healthy lifestyle and determinant of the physical and mental health. According to the WHO, limited physical activity is the fourth most common premature deaths risk factor in the world. Regular sport and active recreation is very important for our health. Physical exercise is the most effective method used by physiotherapists to prevent and slow down the aging process of the body, and consequently, diseases of elderly, such as: osteoporosis, injuries caused by falls, diabetes or hypertension. Physical activity has a positive effect on the quality of life and cognitive functions of elderly. People over 65 years constitute about 40-50% of people who require specialist medical care in the world. Therefore, health and medical professionals dealing with preventive healthcare and treatment of elderly people should have basic knowledge in geriatric rehabilitation, as well as to be able to plan suitable physiotherapy program adequate to the needs of older people. To assess the functional status of the patient, as well as the effectiveness of the training, various types of functional tests are used, specially designed for the elderly. These tests are based on the Comprehensive Geriatric Assessment (COG) considering the state of health, physical and mental fitness as well as socio-environmental conditions. The physiotherapeutic program should be based on functional training involving the entire human body, i.e. nervous, muscular, skeletal, sensory and balance systems.
