Background: The aim of the study was to assess the influence of both physical activity, such as running and dancing, and the personal characteristics of the studied women on the occurrence and progression of premenstrual disorder (PMD). Methods: We surveyed 414 women aged 22-48 who were experiencing the menstrual cycle but not using hormonal contraception. There were two physically active groups, runners (N = 215) and Argentine tango dancers (N = 94), and there was one group not undertaking any physical activity-the control group (N = 104). The research was conducted using the researchers' own questionnaire. Results: The number of days of PMD symptoms in the tango vs. runner vs. control groups are as follows: pre-bleeding (mean: 4.14 vs. 4.86 vs. 4.85; p = 0.024), after the onset of bleeding (mean: 1.76 vs. 2.39 vs. 2.16; p = 0.001), and in total (mean: 5.94 vs. 7.25 vs. 7.01; p < 0.001). The regression analysis results without grouping results are as follows: the number of days of symptoms before bleeding and menarche (B: -0.16; 95% CIs: from -0.29 to -0.04; p = 0.011), the total duration of symptoms and menarche (B: -0.17; 95% CIs: from -0.32 to -0.01; p = 0.036), lower abdominal pain and age (B: -0.05; 95% CIs: 0.92-0.98; p = 0.002), diarrhoea (B: -0.08; 95% CIs: 0.88-0.97; p < 0.001), tearfulness, depressive states and age (B: -0.06; 95% CIs: 0.91-0.97; p < 0.001), skin problems and age (B: -0.05; 95% CIs: 0.92-0.98; p = 0.004), joint pain and age (B: -0.09; 95% CIs: 0.86-0.96; p = 0.001), pain in the lumbar spine (B: -0.06, 95% CIs: 0.91-0.98; p = 0.001), water retention and BMI (B: 0.09; 95% CIs: 0.92-0.98; p = 0.007), and water retention and menarche (B: -0.19; 95% CIs: 0.73-0.94; p = 0.003). Information: generally there is one regression model, we have several here, we have a bit the description. Conclusions: Physical activity such as dancing (tango) shortens the duration of PMD symptoms but does not completely eliminate them. Running does not have as beneficial an effect on symptom relief as dancing. Current age, age when menstruation began (menarche), and BMI were revealed to be important factors influencing the symptoms of premenstrual disorders.
