Human ageing represents one of the biggest socio-economic and healthcare challenges in the 21st century, especially in Europe, with the highest percentage of people above 65 years of age in the entire population (15 %). It has been scientifically proved that programmed physical exercise works to improve health, quality of life, longer maintenance of body function, maintenance of independence and autonomy, as well as prevents falls and their consequences. Therefore, the basic aim of this PhD thesis is to evaluate the effects of a specific exercise program intervention in accordance with scientific discoveries in older age groups within a group treatment, which included individual progress of each participant. The study included 56 senior participants of both genders (>65 years old). There were 30 participants in the experimental and 26 in the control group. Both groups were assessed using various measurements: measurements to assess the range of motion of the hip, shoulder and spine, those to assess the muscular strength of the hip and shoulder, furthermore, measurements to assess the static balance, then the spatial parameters using gait analysis, the ones to assess the quality of the breathing pattern, and others to assess the parameters of the self-assessment questionnaire on quality of life. All the assessed measurements showed no statistically significant differences in the initial measurement between the two groups of participants. Two-factor analysis of variance determined statistical significance of interaction within the TIME / GROUP factors, such as the effect size of change in the repeated measurements between the groups. The results of the study showed that there are statistically significant qualitative changes among the repeated measurements between the experimental and the control group of senior participants, and these were found when measuring the range of motion (ROM) in all movements of the hip, shoulder and spine, as well as while measuring the muscular strength of the hip and shoulder. The changes were also found when measuring the static balance, the quality of the breathing pattern, but also in the social functioning aspect when self-assessing the quality of life. There are no statistically significant qualitative changes among the repeated measurements between the experimental and the control group of senior participants when it comes to measuring the spatial parameters using gait analysis. Using the multiple regression model showed a correlation between the set of reduced predictor variables and the criterion variable of the result change in the physical functioning segment when self-assessing the quality of life.
