Diminuição nas manifestações físicas e psicológicas da síndrome pré-menstrual e de seu impacto funcional através do protocolo de dose mínima

Abstract

Premenstrual Syndrome (PMS) is a set of more than 200 symptoms that involve behavioral factors and somatic, emotional, and cognitive symptoms that are directly related to hormonal changes that occur in the premenstrual period. Amid stressful situations experienced throughout life, strategies are needed to face and adapt to such events. How one chooses to deal with situations is characterized by coping strategies. Women with PMS use different coping strategies compared to women without PMS, making it necessary to understand which strategies are useful for dealing with premenstrual distress and which can be actively modified with methods such as physical activity. The beneficial effect of exercise on PMS symptoms is the reduction of psychological symptoms, but studies with the application of controlled, long-term protocols are still needed. Minimum dose training is like “training snacks”, with summarized training, below that is recommended by global institutions, providing physical and psychological gains to practitioners, compared to a sedentary life. The objectives of the study are: a) to analyze the effects of a minimum dose protocol of 8 weeks on the psychological symptoms of PMS, and b) to identify which coping strategies were used by women affected by PMS during a minimum dose protocol of eight weeks. After selection by inclusion criteria based on information from a Sociodemographic Questionnaire, the PMS Symptom Screening Questionnaire (Premenstrual Symptom Screening Tool - PSST), and the Physical Activity Readiness Questionnaire (PAR-Q), 33 university students were affected. by the SPM, they were referred to two groups: the Resistance Training Group (GTR), which carried out a resistance training program, and the Control Group (CG), which carried out physical tests and filled out questionnaires. Both responded to the questionnaire (Premenstrual Symptom Screening Tool - PSST) on day 1 of their cycle for two menstrual cycles and the coping strategies questionnaire (Brief Cope), given at the end of every week for two months. For data analysis, the linear mixed model was used using Restricted Maximum Likelihood (REML) with the application of the ANOVA III table and Tukey's post hoc for the analysis of PMS symptoms. To analyze coping strategies, the linear mixed model was used for each domain, with descriptive and exploratory analysis. The program used for the analysis was R Studio. The results of the analysis showed significant differences in physical and psychological manifestations, in the second moment, with a reduction in symptoms in the GTR compared to the CG. Differences were also noticed in the functional impacts of symptoms, in the second moment, with a reduction in impacts in the GTR compared to the CG. In the coping analysis, constancy was observed in the choice of strategies, demonstrating that it was not influenced by the minimum dose protocol. We conclude that the practice of resistance training with the minimum dose method helps in the treatment of PMS symptoms by reducing physical and psychological manifestations as well as the functional impact of the symptoms on the lives of those affected. The chosen coping strategies seem to remain constant, not being influenced by the minimum dose protocol.
