Resistance exercise results in health benefits in fibromyalgia. The aim of this study was to determine the factors that mediate change in muscle strength in women with fibromyalgia as a result of resistance exercise.
Sixty-seven women with fibromyalgia (age range 25-64 years) were included. Tests of muscle strength and questionnaires related to pain, fear avoidance and physical activity were carried out. Multivariable stepwise regression was used to analyse explanatory factors for change and predictors for final values of knee-extension force, elbow-flexion force and hand-grip force.
Change in knee-extension force was explained by fear avoidance beliefs about physical activity at baseline, together with change in pain intensity, knee-extension force at baseline, age and body mass index (BMI) (R2=0.40, p = 0.013). Change in elbow-flexion force was explained by pain intensity at baseline, together with baseline fear avoidance beliefs about physical activity, BMI and elbow-flexion force at baseline (R2 = 0.32, p = 0.043). Change in hand-grip force was explained by hand-grip force at baseline, change in pain intensity and baseline fear avoidance (R2 = 0.37, p = 0.009). Final muscle strength was predicted by the same variables as change, except pain.
Pain and fear avoidance are important factors to consider in rehabilitation using resistance exercise for women with fibromyalgia.
抗阻运动对纤维肌痛患者有益健康。本研究旨在确定抗阻运动后介导纤维肌痛女性肌肉力量变化的因素。
纳入67名纤维肌痛女性（年龄范围25 - 64岁）。进行了肌肉力量测试以及与疼痛、恐惧回避和身体活动相关的问卷调查。采用多变量逐步回归分析变化的解释因素以及膝关节伸展力、肘关节屈曲力和握力最终值的预测因素。
膝关节伸展力的变化由基线时对身体活动的恐惧回避信念、疼痛强度变化、基线膝关节伸展力、年龄和体重指数（BMI）共同解释（R2 = 0.40，p = 0.013）。肘关节屈曲力的变化由基线时的疼痛强度、基线时对身体活动的恐惧回避信念、BMI和基线肘关节屈曲力共同解释（R2 = 0.32，p = 0.043）。握力的变化由基线握力、疼痛强度变化和基线恐惧回避共同解释（R2 = 0.37，p = 0.009）。最终肌肉力量的预测变量与变化的变量相同，但不包括疼痛。
对于纤维肌痛女性，在使用抗阻运动进行康复时，疼痛和恐惧回避是需要考虑的重要因素。
