title: Changes in motivational outcomes after a supervised resistance exercise training intervention in lung cancer survivors.
abstract: BACKGROUND
  Short-term supervised exercise interventions improve health-related fitness in lung cancer survivors; however, sustained exercise is required to maintain the health benefits. The impact of exercise interventions on motivational outcomes may be important for long-term exercise adoption.
  
  
  OBJECTIVE
  The objective of this study was to examine the effects of a 10-week supervised progressive resistance exercise training program on lung cancer survivors' motivational outcomes based on the Theory of Planned Behavior (TPB).
  
  
  METHODS
  Posttreatment lung cancer survivors were recruited to undergo a 10-week supervised resistance exercise training intervention. The 2-component model of the TPB was measured at baseline and after intervention.
  
  
  RESULTS
  Fifteen participants completed assessments of TPB measures. Significant increases in self-efficacy (P = .022) and perceived controllability (P = .032) and a nonsignificant increase in affective attitude (P = .090) were observed after intervention. Intention was significantly lower at postintervention (P = .044). Significant correlates of postintervention intention were instrumental attitude (P = .001), self-efficacy (P = .004), perceived behavioral control (P = .009), and affective attitude (P = .044). At postintervention, self-efficacy was significantly correlated with planning (P < .046).
  
  
  CONCLUSIONS
  Short-term supervised resistance exercise training may improve some motivational outcomes for lung cancer survivors. Intentions appeared to be weakened after the intervention, but there are methodological explanations for this finding.
  
  
  CONCLUSIONS
  Participation in short-term supervised resistance exercise may be an effective method to improve some motivational factors related to exercise in lung cancer survivors. More research is needed to examine the long-term effects of supervised resistance exercise on motivational outcomes in lung cancer survivors. Strategies to maintain motivational changes that occur following a supervised resistance exercise intervention need to be investigated.
