Introduction

Physical activity reduces fatigue and depression while improving quality of life in cancer survivors. Exercise is generally considered safe and is recommended to survivors of all ages. Despite the high prevalence of cancer in the elderly, few studies address physical activity interventions targeting this older population. Fit & Strong! is an evidence-based physical activity program shown to improve level of physical activity, exercise-self-efficacy, and mood in older adults with osteoarthritis. This study tests the feasibility and short-term impact of the Fit & Strong! exercise program adapted for older cancer survivors.

Methods

Participants were cancer survivors at least 50 years of age who were not on active treatment with intravenous chemotherapy or radiation. They participated in the 8-week Fit & Strong! program, which included three 90-min sessions per week; 60 min of group physical activity and 30 min of education. Education on osteoarthritis was removed from the Fit & Strong! program and replaced with relevant topics on cancer survivorship issues. Feasibility was measured by the ability to recruit and retain older cancer survivors. Pre and post-intervention surveys evaluated the effect of the intervention on physical activity and quality of life.

Results

The study enrolled 72 cancer survivors to participate in an 8-week exercise program. The mean age of participants was 70. Over two-thirds (68%) of participants completed the program and with a mean attendance rate of 75% (18 of 24 sessions). No safety issues occurred. Improvements from baseline to post-intervention were observed for self-reported minutes of physical activity per week, self-efficacy for aerobic exercise, and symptoms related to depression and anxiety.

Conclusion

This study was successful in recruiting and retaining a population of older cancer survivors to participate in a group exercise program. Significant improvement in level of physical activity and mood suggests this evidence-based physical activity intervention can be adapted to promote health benefits in cancer survivors. Additional studies are necessary to confirm efficacy and assess long-term benefits.
