To examine the associations of non-bouted moderate-to-vigorous physical activity (MVPA) and patterns of MVPA in bouts ≥10 minutes with pain, physical fatigue, and disease severity in women with fibromyalgia, and test whether these associations are independent of sedentary time (ST) and physical fitness (PF).
Cross-sectional study carried out from November 2011 to January 2013.
University facilities and fibromyalgia associations.
Women with fibromyalgia (N=439; 51.3±7.6y).
Not applicable.
ST and MVPA were measured with triaxial accelerometry, and PF with the Senior Fitness test battery. We assessed pain, physical fatigue and disease severity with diverse questionnaires.
Total time in non-bouted MVPA only was independently associated with lower physical fatigue (B=-0.012; P=.010) and disease severity (B=-0.068; P=.007) in women with fibromyalgia, regardless of PF but not of ST. Patterns of bouted MVPA were overall associated with symptoms independently of ST or PF. The strongest regressor was the maximum time in MVPA bout (min/bout), which was consistently and independently associated with pain, physical fatigue and disease severity after controlling for ST or PF (all, P≤.002). Patients meeting bouted physical activity guidelines displayed lower disease severity than those not meeting guidelines (bouted or non-bouted) and those meeting non-bouted physical activity guidelines (all, P≤.008).
Patterns of MVPA performed in bouts ≥10 minutes were overall consistently and independently associated with core symptoms (pain and fatigue) in fibromyalgia and the overall disease severity, regardless of ST or PF. The results suggest that longer bouts of continuous MVPA are associated with better symptoms profile in this population, which needs to be corroborated in longitudinal research.
研究非成组中等到剧烈身体活动（MVPA）与成组 10 分钟以上 MVPA 模式与纤维肌痛女性的疼痛、身体疲劳和疾病严重程度之间的关联，并检验这些关联是否独立于久坐时间（ST）和身体适应性（PF）。
2011 年 11 月至 2013 年 1 月进行的横断面研究。
大学设施和纤维肌痛协会。
纤维肌痛女性（N=439；51.3±7.6 岁）。
无。
ST 和 MVPA 使用三轴加速度计测量，PF 使用老年人健身测试电池测量。我们使用各种问卷评估疼痛、身体疲劳和疾病严重程度。
仅非成组 MVPA 总时间与纤维肌痛女性较低的身体疲劳（B=-0.012；P=.010）和疾病严重程度（B=-0.068；P=.007）独立相关，与 PF 无关，但与 ST 有关。成组 MVPA 模式总体上与症状独立相关，与 ST 或 PF 无关。最强的回归量是 MVPA 成组中的最大时间（min/组），在控制 ST 或 PF 后，它与疼痛、身体疲劳和疾病严重程度始终独立相关（均，P≤.002）。符合成组身体活动指南的患者比不符合指南（成组或非成组）和符合非成组身体活动指南的患者的疾病严重程度更低（均，P≤.008）。
≥10 分钟的成组 MVPA 模式总体上与纤维肌痛的核心症状（疼痛和疲劳）和整体疾病严重程度独立相关，与 ST 或 PF 无关。结果表明，在该人群中，更长时间的连续 MVPA 与更好的症状谱相关，这需要在纵向研究中加以证实。
