The effect of aquatic and land exercise on the mental well-being of women following breast cancer surgery-comparative study

Abstract

Abstract Purpose Women after surgical treatment of breast cancer are less likely to engage in physical activity and may exhibit depressive symptoms even for many years post-treatment. The aim of the study was to compare the impact of 6 months aquatic and land exercise on mental well-being of women after breast cancer surgery. Methods The study was based on a survey which involved a total of 90 women ≥ 50 years of age (including 60 subjects after treatment of breast cancer ≥ 2 years after surgery and 30 healthy control). The study participants were divided into three groups, i.e. women attending general exercise sessions in a gym (A, n = 30), participating in aquatic exercise (B, n = 30), as well as healthy female peers reporting no regular physical exercise for the period of 6 months (C, n = 30). The present data were acquired using standardized questionnaires designed to assess physical activity (IPAQ-SF), mental well-being (WHO-5) and level of anxiety, i.e., Generalized Anxiety Disorder Questionnaire (GAD-7). Results Both the aquatic and land exercise had positive effect on mental well-being of woman after breast cancer surgery and there were no significant differences between them. Analysis of the anxiety level (GAD-7) confirms that women after breast cancer treatment were more exposed to a feeling of generalised anxiety disorder, i.e. 8.67 vs. 6.73, 4.5 (p = 0.001). The results of WHO-5 index were significantly higher in the A and B groups comparing to healthy control, i.e. 13.27 vs. 14.18; 10.10 (p < 0.001), but the obtained results still indicate the low self-esteem of the study group. Women after breast cancer surgery who regularly participated in aquatic exercise were engaged in more vigorous physical activity compared to the other groups, i.e. 1049.33 vs. 521.33; 860.00 MET min/week (p = 0.001). Conclusion Regardless of the type of physical activity, 6 months aquatic and land exercise contributed to improved mental well-being and ensured adequate levels of moderate physical activity of woman after BC surgery. Regular physical activity is crucial in the rehabilitation after mastectomy and can be an effective treatment to achieve beneficial mental outcomes.
