Introduction: Physical activity is any movement performed by activating skeletal muscles and using energy. It has a positive effect on physical and mental health. Regular physical activity improves fitness, increases muscle strength and endurance, and prevents the onset of non-communicable diseases. Regular physical activity reduces the risk of chronic non-communicable diseases and has a positive effect on mental health. Physical activity has a significant impact on the body of women, which is especially sensitive in specific periods of life such as adolescence, pregnancy, the postpartum period and menopause. The aim of this research was to determine how regular physical activity affects the cardiorespiratory status of women. Materials and methods: 24 respondents participated in the research, included in the program of organized regular physical activity in the period from February 1, 2024. Until 31.03.2024. years. Before and after exercise, oxygen saturation was measured, a six-minute walk test was performed, and the body mass index was determined. Upon completion of data collection, the obtained data were processed using appropriate statistical methods in the Statistica 13.3 program (TIBCO Software Inc.). Results: Of the three hypotheses, two were confirmed. In the first hypothesis, statistical analysis using the Wilcoxon test confirms that there are no significant differences in the body mass index of the subjects between the first and second measurements, p=0.422. The research confirmed that there are significant differences between oxygen saturation before and after training - p=0.003. The test subjects achieved significantly better results in the 6-minute walk test after the two-month physical activity program (p<0.0001). Conclusion: Regular physical activity contributes to a significant improvement of cardiorespiratory status, especially with increasing age. Although short-term TA can bring certain benefits, an integrated long-term approach that includes an overall change in lifestyle habits is certainly more effective in general health improvement.
