An Evaluation of Exercise-Related Self-Efficacy Metrics Following a Resistance Training Program in Individuals Treated for Cancer

As the number of cancer survivors grows, managing treatment side effects and promoting healthy behaviors like physical activity is crucial. Low exercise self-efficacy, an individual's belief in their capability to perform exercise, is a significant barrier to physical activity adherence. This study assessed if an 8-week supervised resistance training program could improve self-efficacy for exercise (SEE) and outcome expectations of exercise (OEE) in individuals treated for cancer. Participants (n=25) attended twice-weekly, one-hour sessions. SEE and OEE scales were administered pre- and post-intervention. Results indicated a significant increase in SEE scores (mean difference = 8.96 ± 19.87, p = 0.041), demonstrating an enhanced belief by participants in their ability to exercise. However, OEE scores showed no significant change (mean difference = -1.92 ± 5.79, p = 0.80). These findings suggest that structured resistance training effectively boosts perceived ability to exercise in individuals treated for cancer, which is vital for initiating and maintaining physical activity. While SEE improved, positively influencing beliefs about exercise benefits (OEE) may require different or longer interventions. Resistance training is a valuable tool in the field of cancer survivorship care to promote increased self-efficacy and adherence to physical activity regimens to combat the side effects of cancer treatment.
