运动能力是癌症患者死亡率的重要决定因素，因此了解运动能力的可能决定因素将为患有癌症恶病质的个体带来身心上的益处。 探讨运动能力与外周肌和呼吸肌力量、体力活动、疲劳之间的关系以及患有癌症恶病质的受试者的生活质量。该研究包括 31 名被诊断患有癌症恶病质的患者。通过 6 分钟步行测试评估功能能力，通过手测力计评估握力和近端肌肉质量，通过最大呼气压力和最大吸气压力测量评估呼吸肌力量，通过国际体育活动简表问卷评估体力活动，通过短暂疲劳评估疲劳程度EORT-QLQ-C30 的库存和生活质量。使用 Spearman 或 Pearson 检验确定功能能力与连续自变量之间的关系。运动能力与呼气肌力量（r = 0.75，p < 0.001）、活动水平（r = 0.68，p < 0.001）之间观察到强正相关。 ）和生活质量全球健康状况（r = 0.74，p < 0.001）。相反，运动能力与疲劳严重程度之间存在很强的负相关性（r = -0.64，p < 0.001）。癌症恶病质患者较高的运动能力与疲劳减轻、呼吸肌力量改善、体力活动水平增加和体力活动增强有关。生活质量。在为癌症恶病质患者设计康复计划或运动干预措施时，评估他们的运动能力并相应调整计划至关重要。

Exercise capacity is a significant determinant of mortality for cancer patients, so knowing the possible determinants of exercise capacity will produce physical and psychological benefits for individuals with cancer cachexia.To investigate the relationship between exercise capacity on peripheric and respiratory muscle strength, physical activity, fatigue and quality of life in subjects with cancer cachexia.The study included 31 patients diagnosed with cancer cachexia. Functional capacity was assessed by 6-Minute Walk Test, hand grip strength and proximal muscle mass by hand dynamometer, respiratory muscle strength by the Maximum Expiratory Pressure and Maximum Inspiratory Pressure measurements, physical activity by International Physical Activity Questionnaire Short Form, fatigue by Brief Fatigue Inventory, and quality of life by EORT-QLQ-C30. The relationship between functional capacity and continuous independent variables was determined using Spearman's or Pearson's tests.A strong positive correlation was observed between exercise capacity and expiratory muscle strength (r = 0.75, p < 0.001), activity level (r = 0.68, p < 0.001), and quality of life global health status (r = 0.74, p < 0.001). Conversely, a strong negative correlation was found between exercise capacity and fatigue severity (r = -0.64, p < 0.001).Higher exercise capacity in cancer cachexia patients is linked to reduced fatigue, improved respiratory muscle strength, increased physical activity levels, and enhanced quality of life. When designing rehabilitation programs or exercise interventions for individuals with cancer cachexia, it is crucial to assess their exercise capacity and tailor the programs accordingly.
