- Characterization of physical activity levels in female breast cancer survivors: relationship with lymphedema (AtiLinf)Publication . Duarte, Alice Ralheta; Neto, Carla Martinho; Prates, Leonor; Lobo, Pablo; Tomás, Maria TeresaThe development of lymphedema (LE) is a major concern in breast cancer treatment, and it is crucial to understand the best ways to prevent and treat it. Physical activity is effective, safe, and feasible in controlling complications arising from treatments, as well as improving function and quality of life in breast cancer survivors. This study aimed to investigate the relationship between physical activity and grip strength, as well as LE development, in breast cancer survivors. A cross-sectional analytical study was conducted, and women who had survived breast cancer between 1 and 5 years after surgery were selected. Participants completed the International Physical Activity Questionnaire Short Form. The volume of the upper limb (UL) was measured using perimetry, handgrip strength was assessed with the JAMAR dynamometer, and the Actigraph accelerometer was placed on the waist. It was found that 50% of the sample was overweight, 28.3% were obese, and 52% of the participants had grip strength below the recommended level. They had an average energy expenditure of 1.2 (0.1) metabolic equivalents, 8.3 (1.8) hours/day of sedentary activity, and spent an average of 61% of their awake time in sedentary activity per day. Significant correlations were found between grip strength on the affected side and the difference in volume between the UL (rp = -.303, P = .041), as well as between body mass index (BMI) and the difference in volume between the UL (rp = .341; P = .020). Moreover, a significant correlation between BMI and the volume of the affected UL was found (rp = .848, P = .000). BMI and grip strength of the affected side were identified as significant predictors of LE, both with P values less than .05. Although physical activity cannot directly prevent LE, it may contribute by helping to control BMI and promote higher levels of grip strength, both of which are important factors in the prediction of LE.
- Female breast cancer survivors: how can physical activity and grip strength impact the development of lymphedema?Publication . Duarte, Alice Ralheta; Neto, Carla Martinho; Prates, Leonor; Lobo, Pablo; Tomás, Maria TeresaIntroduction: Over the past few years there has been an increase in the number of breast cancer survivors, which implies living with the chronic implications resulting from the treatment. These complications harm the function, participation, and quality of life of this population. The development of lymphedema (LE) is one of the main complications and concerns that arise from breast cancer treatment and therefore it is crucial to understand the best way to prevent and treat its development. Scientific evidence suggests that LE prevention involves promoting active and healthy lifestyles by changing behaviors and controlling changeable risk factors. Practicing physical activity (PA) brings various clinical benefits, which are effective, safe, and viable in controlling complications after breast cancer treatments, as well as improving the function and quality of life of the population being studied. In general, greater benefits were demonstrated for women with increased physical activity levels, with a moderate PA (3-6 MET) considered feasible and sufficient to improve the prognosis of these patients (International Society of Lymphology, 2020). On the other hand, this population has a reduced tendency to change their lifestyle and do PA. In this regard, it becomes relevant to conduct a study that characterizes the physical exercise habits of Portuguese women who survived breast cancer with LE. Objectives: Study the relationship between physical activity (PA) with grip strength and lymphedema volume in female breast cancer survivors. Methods: A cross-sectional analytical study was conducted, with a convenience sample. Women who survived breast cancer between 1 and 5 years after surgery were selected and women with bilateral surgery and who have not finished the active phase of the treatments were excluded.
