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.
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).
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.
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).
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.
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.
短期监督运动干预可改善肺癌幸存者的与健康相关的体能；然而，需要持续运动以维持健康益处。运动干预对动机结果的影响对于长期运动的采用可能很重要。
本研究的目的是根据计划行为理论（TPB），检验 10 周监督渐进式抗阻训练计划对肺癌幸存者的动机结果的影响。
招募接受治疗的肺癌幸存者参加 10 周的监督抗阻训练干预。在基线和干预后测量 TPB 的 2 个组成部分模型。
15 名参与者完成了 TPB 措施的评估。干预后，自我效能感（P =.022）和感知可控性（P =.032）显著增加，情感态度（P =.090）略有增加。干预后意向明显降低（P =.044）。干预后意向的显著相关因素是工具性态度（P =.001）、自我效能感（P =.004）、感知行为控制（P =.009）和情感态度（P =.044）。干预后，自我效能感与计划显著相关（P <.046）。
短期监督抗阻训练可能会改善肺癌幸存者的某些动机结果。干预后，意图似乎减弱，但这一发现有其方法学解释。
参加短期监督抗阻训练可能是改善肺癌幸存者与运动相关的某些动机因素的有效方法。需要进一步研究来检验监督抗阻训练对肺癌幸存者动机结果的长期影响。需要研究保持监督抗阻运动干预后发生的动机变化的策略。
