Fibromyalgia (FM) is a chronic pain condition that causes impaired functional capacity, possibly through the adoption of sedentary behaviour. However, little is known regarding physical activity level and its relationship with physical performance in women with FM.
To compare physical activity level, assessed using the International Physical Activity Questionnaire (IPAQ), and physical performance, measured using the six-minute walk test (6MWT), in women with and without FM, and to examine the possible relationships between physical activity level and physical performance in both groups.
The study included 30 women diagnosed with FM (patients) and 28 healthy women (controls) who answered the IPAQ and performed the 6MWT.
Patients and controls self-reported similar physical activity level, considering both the total score and all IPAC subcomponents (P > 0.05). However, the FM patients had worse physical performance in the 6MWT (patients, 441.8 ± 84.1 m vs. controls, 523.9 ± 80.3 m; P < 0.01). There were no relationships between the distance walked in the 6MWT and the IPAQ variables for the control group. However, the distance walked by patients in the test showed a significant correlation (P < 0.05) with the total score and the subcomponents transport, household activities, and physical activities of moderate intensity in the IPAQ.
Women with FM had physical activity levels similar to women without FM but exhibited worse physical performance. This functional impairment may be related to lifestyle adopted because there was a relationship between physical activity level and physical performance in those patients.
纤维肌痛（FM）是一种慢性疼痛病症，可能通过久坐行为导致功能能力受损。然而，关于FM女性的身体活动水平及其与身体机能的关系，我们知之甚少。
比较使用国际身体活动问卷（IPAQ）评估的有FM和无FM女性的身体活动水平，以及使用六分钟步行试验（6MWT）测量的身体机能，并研究两组中身体活动水平与身体机能之间的可能关系。
该研究纳入了30名被诊断为FM的女性（患者）和28名健康女性（对照组），她们回答了IPAQ并进行了6MWT。
考虑总分和所有IPAQ子成分，患者和对照组自我报告的身体活动水平相似（P>0.05）。然而，FM患者在6MWT中的身体机能较差（患者为441.8±84.1米，对照组为523.9±80.3米；P<0.01）。对照组6MWT中的步行距离与IPAQ变量之间没有关系。然而，患者在测试中的步行距离与IPAQ中的总分以及交通、家务活动和中等强度身体活动的子成分显示出显著相关性（P<0.05）。
患有FM的女性与未患FM的女性身体活动水平相似，但身体机能较差。这种功能损害可能与所采用的生活方式有关，因为这些患者的身体活动水平与身体机能之间存在关联。
