Abstract

Purpose: Exercise is important to address physical and emotional effects of breast cancer treatment. This study examines effects of a personal trainer led exercise intervention on physical activity levels, physical function and quality of life (QoL) in breast cancer survivors. Methods: Women post active breast cancer treatment were recruited from 2015 to 2017, randomized to immediate exercise or wait-list control, and received three personal training sessions for up to 30 weeks. Physical activity and function were assessed by pedometer, and tests of endurance, strength, and flexibility. Self-reported physical activity, physical activity self-efficacy, and QoL were also assessed. Results: 60 women were randomized to immediate intervention (n = 31) or wait-list control (n = 29). Subjects were aged (mean ± SD) 56 ± 10 years. On the endurance test, the exercise group significantly improved (increase of 18 ± 20 steps vs control 9 ± 12 steps) (p = 0.036). On the strength test, the exercise group significantly improved (increase of 4 ± 3 curls vs control 1 ± 3 curls) (p = 0.002). After intervention, change (mean ∆ ± SD) in the FACT-ES physical well-being subscale score was 1 ± 2 in the exercise group and − 1 ± 2 in the control group (p = 0.023). Improvement in Self-efficacy and Physical Activity (SEPA) score was significant with a change (mean ∆ ± SD) of 2 ± 5 for exercise vs 0 ± 5 for control (p = 0.047). The number of steps/day, back scratch test, weight, and self-reported physical activity did not significantly improve with intervention. Conclusions: The intervention yielded significant improvements in endurance and strength but not physical activity or quality of life. Implications for cancer survivors: Future efforts to explore feasible ways to support patient’s physical activity efforts need to be undertaken.
