Background: Regular exercise is an important tool to address physical and emotional effects of breast cancer treatment. However, many breast cancer survivors do not meet minimum recommended levels of physical activity. This study examines effects of a personal trainer led exercise intervention on physical activity levels and physical function in breast cancer survivors. Methods: Women who completed active treatment for breast cancer were recruited from oncology clinics and survivorship programs from September 2015-to September 2017. Subjects were randomized to an immediate exercise or a wait-list control group. The intervention included 3 personal training sessions over a period of up to 30 weeks. Physical activity and function were assessed before and after intervention by pedometer (7-day record) and endurance step test (steps in 2 minutes). Results: 60 women were randomized to immediate intervention (n = 31) or wait-list control (n = 29). Subjects were an average of (mean ± SD) 56 ± 10 years old and 2 ± 1 years since breast cancer diagnosis. At baseline, the exercise group averaged (mean ± SD) 5236 ± 2214 steps/day and 101 ± 23 steps on 2-minute step test while the control group averaged 5856 ± 2916 steps/day and 106 ± 23 steps on 2-minute step test. After intervention, change (mean ∆± SD) was 143 ± 1842 steps/day in the exercise group and 79 ± 1862 steps/day in the control group (p= 0.9). On the 2-minute step test, the exercise group increased 18 ± 20 steps and the control group increased 9 ± 12 steps (p= 0.07). Conclusions: While there was some improvement in physical function after the personal-trainer led intervention, the short duration and intensity of the intervention may have diminished the effects. Our results suggest a multi-faceted approach may be needed to support significant changes in breast cancer survivors’ physical activity. Future efforts employing a multidisciplinary team, which includes a certified personal trainer, and with larger patient samples may help address this possibility.
