Hispanic ethnicity as a moderator of the effects of aerobic and resistance exercise on physical fitness and quality-of-life in breast cancer survivors

This study aimed to examine the relationships between activity restriction, quality of life (QoL), and hematopoietic profile in breast cancer survivors according to exercise modality. The subjects in this study were 187 female breast cancer survivors among a total of 32,631 participants in the Korea National Health and Nutrition Examination Survey, which was conducted from 2016 to 2018. The selected subjects participated in a questionnaire survey and blood analysis. A cross-analysis was conducted to determine the relationship between participation in various modality of exercise (e.g., aerobic exercise, resistance exercise, walking exercise). The phi coefficients or Cramer’s V value for activity restriction and QoL were calculated; an independent t-test was conducted to evaluate the differences between hematopoietic profiles based on the modality of exercise. Statistically significant correlations were seen between obesity and aerobic exercise and walking frequency, as well as between diabetes and aerobic exercise and activity restriction. With respect to QoL, there was a statistically significant correlation between participation in aerobic exercise and exercise ability, participation in aerobic exercise and anxiety/depression, participation in resistance exercise and subjective health status, participation in resistance exercise and exercise ability, and participation in weekly walking exercise and self-care ability. Regarding hemodynamic changes, red blood cells increased significantly in breast cancer survivors who participated in weekly resistance exercise compared to in those who did not. In conclusion, exercise participation had a positive effect on activity restriction, QoL, and hematopoietic profile in breast cancer survivors; in particular, some modalities of aerobic exercise were more effective.

143 Background: Breast cancer treatment has adverse effects. The aim of this study was to examine the effects of a multidisciplinary oncologic rehabilitation program on health related quality of life (HRQoL), cancer related fatigue (CRF), muscle strength, physical fitness and anthropometrics in breast cancer survivors. Methods: This quasi-experimental study included 30 early breast cancer patients in the first year following treatment. Patients completed a 12-week exercise program for 4 hours a week combined with lifestyle guidance for 2 hours a week. The supervised training sessions consisted of aerobic exercises combined with muscular strengthening exercises. Measurements were carried out at baseline (T0), at the end of the intervention (T1) and at 12-weeks follow-up (T2). HRQoL (EORTC QLQ-C30 questionnaire) and CRF (FACIT-Fatigue questionnaire), were measured at T0, T1 and T2. Muscle strength (handgrip dynamometer) was measured at T0 and T1. Physical fitness and anthropometrics were assessed at T0 and T1 using spiro ergometrics, bioimpedance and waist- and hip circumference. Results: Significant positive changes in HRQoL were found, especially for physical functioning (p = 0.004) and dyspnea (p = 0,003) at T1, but HRQoL decreased at T2. Weight, BMI, waist - and hip circumference and fat free mass decreased significantly (respectively p = 0,030; p = 0,047; p = 0,020; p = 0,041 and p = 0,003). Body impedance increased significantly over time (p = 0,034). There was a significant improvement in CRF at T1 (p = 0.03), that was no longer significant at T2. No significant improvements were found in muscle strength at the affected side (p = 0.16) and the non-affected side (p = 0.95). Physical fitness increased significantly for VO2max at the maximal progressive cycle test (p = 0.005). Conclusions: This study reports significant improvements in HRQoL, anthropometric characteristics, CRF and physical fitness after a 12-week rehabilitation program. The declines between T1 and T2 may be explained by discontinuation of physical activity. Further research should use randomized clinical trials to examine the effectiveness of rehabilitation programs with different contents, duration and initiation.
