      abstract     = {Performing 2-3 exercise sessions/week may relieve
                      therapy-related side effects of breast cancer patients
                      (BRCA) and improve their quality of life. However,
                      attendance to the exercise sessions is often impaired. Thus,
                      we investigated patterns and possible influencing factors of
                      attendance to an aerobic (AT) or resistance training (RT)
                      intervention in BRCA during neoadjuvant chemotherapy.BRCA (N
                      = 122) were randomly allocated to supervised AT or RT twice
                      weekly during neoadjuvant chemotherapy (18 ± 4 weeks).
                      Attendance was calculated individually and group-wise per
                      training week as the percentage of the performed sessions
                      out of the prescribed sessions. Possible influencing factors
                      were investigated using multiple regression analyses.Mean
                      individual attendance was $44.1\%$ ± $29.3\%$ with no
                      significant differences between the groups. Group-wise
                      attendance was highest in the first 6 weeks of training with
                      ≥ $60\%$ for AT and ≥ $50\%$ for RT, but decreased over
                      the course of the intervention accompanying chemotherapy.
                      Significantly higher attendance was associated with not
                      having vs. having nausea (ß = - 14.57; p = 0.007) and not
                      having vs. having pain (ß = - 12.07; p = 0.12), whereas
                      fatigue did not show any association (ß = - 0.006; p =
                      0.96). Having been randomized into a preferred intervention
                      group $(48.8\%)$ showed no association with attendance. Yet,
                      patients' rating of the exercise intervention as 'good'/
                      'very good' $(58.7\%)$ was significantly associated with
                      higher attendance (p = 0.01).For both exercise
                      interventions, group-wise attendance/training week decreased
                      during chemotherapy despite good intervention ratings. While
                      some patients never started, others trained almost
                      constantly twice weekly. The study revealed that patients
                      who are nauseous or experience pain may need more support to
                      attend more exercise sessions. Trial Registration
