|Abstract: ||Introduction: Supervised exercise may have positive effects on motivation and continued
exercise in cancer survivors, but few randomized controlled trials have examined this issue. Here, we report the motivational outcomes
and longer-term exercise behavior from the Healthy Exercise for Lymphoma Patients trial. Methods: Lymphoma patients were randomly
assigned to 12 wk of supervised aerobic exercise (SUP, n = 60) or usual care (UC, n = 62). Motivational outcomes from the theory
of planned behavior were assessed at baseline, after intervention, and at 6-month follow-up using standardized measures. Exercise
behavior was self-reported at baseline and 6-month follow-up using the Godin Leisure Time Exercise Questionnaire. Results: Data were
available from 95% of participants after intervention and 90% at 6-month follow-up. SUP attended a median of 92% of the supervised
exercise sessions. After intervention, SUP was superior to UC for intention (+0.41 (+0.09 to +0.72), P = 0.012) and perceived behavioral
control (+0.36 (+0.01 to +0.72), P = 0.047) and borderline superior for self-efficacy (+0.35 (j0.02 to +0.72), P = 0.060). At 6-month
follow-up, SUP reported significantly more exercise minutes compared with UC (+133 (+38 to +227), P = 0.006), and a higher
percentage of SUP participants were meeting public health exercise guidelines (+25.6% (+8.2% to +43.0%), P = 0.004). Path analysis
showed that perceived behavioral control partially mediated the effects of supervised exercise (group assignment) on exercise behavior
at 6-month follow-up (meeting exercise guidelines). Conclusions: Supervised exercise has motivational effects in lymphoma patients
and improves longer-term exercise behavior. Strategies to further enhance the motivational value of supervised exercise are warranted.|
