###### Abstract  
This longitudinal study aimed to analyze the effects of a team rowing-based training program on physical fitness and anthropometric parameters in female breast cancer survivors (\(n=40\); \(56.78\pm\)\(6.38\) years). Participants were divided into two groups: one rowed in fixed seat rowing (FSR) boats (\(n=20\); \(56.35\pm\)\(4.89\) years) and the other in sliding seat rowing (SSR) boats (\(n=20\); \(57.20\pm\)\(7.7\) years). Both groups engaged in two 75-min sessions per week for 24 weeks. Significant improvements were observed in both groups in resting heart rate (FSR: \(-10.65\) bpm; SSR: \(-8.45\) bpm), heart rate at the beginning of the 6-min walk test (6 MWT) (FSR: \(-10.7\) bpm; SSR: \(-11.25\) bpm), and heart rate at the end of the test (FSR: \(-13.85\) bpm; SSR: \(-20.35\) bpm). Blood pressure improved significantly in both diastolic blood pressure (FSR: \(-12.35\) mmHg; SSR: \(-19.25\) mmHg) and systolic blood pressure (FSR: \(-13\) mmHg; SSR: \(-16.95\) mmHg). Additionally, both groups increased the distance covered in the 6 MWT (FSR: \(+63.05\) m; SSR: \(+93.65\) m). These results suggest that a rowing training program is a viable and safe activity for female breast cancer survivors, improving cardiac function, blood pressure, and cardiorespiratory capacity, particularly in sliding seat boats.

factor, since current breast cancer treatments, based on chemotherapy, radiotherapy, and endocrine therapies, have a potentially deleterious effect related to cancer-induced cardiotoxicity and, consequently, to the development of cardiovascular disease [8; 9]. Therefore, there is a need to examine which types of complementary non-pharmacological interventions can help to reduce the risk of developing cardiovascular disease in female breast cancer survivors. The diagnosis of cancer is often accompanied by drastic changes in a person's life. Taking into account that the lifestyle adopted can positively influence the chances of survival of the disease [12], as well as protect against the possible sequelae of treatment [13; 14], scientific evidence has shown that engaging in physical exercise can reduce the onset of symptoms associated with cancer treatment and improve physical fitness and mental health [1; 6; 15; 16]. This research has shown that a controlled training program can produce significant improvements in aerobic capacity, as well as an increase in muscle mass and strength, in addition to improving functionality of the upper limbs in women with breast cancer [17; 18; 19; 20]. The majority of the studies consulted affirm that physical activity positively influences health status, mood, and body composition, positively affecting the quality of life of survivors [15; 16; 21; 22; 23]. Despite the proven benefits of exercise and its positive impact on the health of women with breast cancer [1; 8; 24; 25], the level of physical activity is significantly reduced during cancer treatment [26], and remains even lower than it was before diagnosis [25]. Unfortunately, studies have shown that women who have been diagnosed with breast cancer decrease their physical activity by 11%, falling even further in those who are treated with chemotherapy (50%) and radiotherapy (24%), compared to untreated women [26]. Fatigue, low motivation, kinesiophobia, fear of lymphedema, and difficulties in accessing sports facilities are the main barriers to participation in physical activities in cancer patients [4]. Additionally, we must also consider that persistent chronic pain and sensory changes are common sequelae following breast cancer surgery. Studies report that between 20% and 60% of women experience persistent pain, primarily felt in the anterior chest, arms, and axillae after breast cancer surgery, significantly worsening their quality of life [27; 28].
