Research Progress on the Effects of Walking Exercise on Negative Emotions in Breast Cancer Patients Undergoing Chemotherapy

乳腺癌是全球女性最常见的恶性肿瘤之一。化疗作为其重要治疗手段虽能有效控制病情，但常引发负性情绪等问题，显著降低患者生活质量和治疗依从性。步行运动作为一种经济、易行的干预方式，在改善乳腺癌化疗患者心理状态方面展现出显著潜力。然而，国内相关研究仍较匮乏。本文通过系统综述，探讨步行运动对乳腺癌化疗患者负性情绪的干预效果、作用机制及临床适用性，揭示当前研究局限性。为步行运动在我国乳腺癌化疗患者情绪管理中的规范化应用提供循证依据。Breast cancer is the most common malignant tumor among women worldwide. Although chemotherapy serves as a critical treatment modality and effectively controls disease progression, it often induces adverse effects such as negative emotions significantly impairing patients’ quality of life and treatment adherence. Walking exercise, as a cost-effective and accessible intervention, has demonstrated significant potential in improving the psychological well-being of breast cancer patients undergoing chemotherapy. However, relevant domestic research remains limited. This systematic review examines the efficacy, underlying mechanisms, and clinical applicability of walking exercise in managing negative emotions among this patient population, while highlighting current research limitations. The findings provide evidence-based support for standardizing the implementation of walking exercise in emotional management for breast cancer patients undergoing chemotherapy in China.
