Objectives Supervised exercise is beneficial for lymphoma patients, but it needs to be maintained to optimize long‐term benefits. Here, we report the predictors of follow‐up exercise behavior 6 months after a randomized controlled trial in lymphoma patients. Methods Lymphoma patients were randomly assigned to 12 weeks of supervised aerobic exercise ( n = 60) or usual care ( n = 62). At baseline and post‐intervention, data were collected on demographic, medical, health‐related fitness, quality of life, and motivational variables. At 6‐month follow‐up, participants were mailed a questionnaire that assessed exercise behavior and were categorized as meeting or not meeting public health exercise guidelines. Results At 6‐month follow‐up, 110 participants (90.2%) responded, of which 61 (55.5%) were meeting public health exercise guidelines. In univariate analyses, 16 variables predicted 6‐month follow‐up exercise behavior. In a stepwise regression analysis, five variables entered the model and explained 38% ( p < 0.001) of the variance including the following: accepting a post‐intervention exercise prescription ( β = 0.33; p < 0.001), achieving a higher peak power output at post‐intervention ( β = 0.28; p = 0.001), experiencing a larger positive change in perceived behavioral control ( β = 0.18; p = 0.028), having Hodgkin lymphoma ( β = 0.19; p = 0.025), and having a stronger post‐intervention intention ( β = 0.18; p = 0.034). Conclusion Exercise behavior in lymphoma patients 6 months after a randomized trial was predicted by a wide range of demographic, medical, health‐related fitness, quality of life, and motivational variables. These findings may help facilitate the uptake of self‐directed exercise after short‐term supervised exercise in lymphoma patients. Copyright © 2011 John Wiley & Sons, Ltd.
