The purpose of this study was to determine the influence of 2 different periodized exercise rehabilitation programs (resistance training [RT] and aerobic training [AT]) on musculoskeletal health, body composition, pain, disability, and quality of life (QOL) in chronic (>or=3 months; >or=3 d.wk) nonspecific low-back pain (CLBP) persons. Twenty-seven CLBP subjects were randomly assigned to 1 of 3 groups, 1) RT (n = 9), 2) AT (n = 9), or 3) control (C; n = 9). Subjects were tested at baseline and at weeks 8 and 16 of training. Intensity and volume were periodized in the training groups. Significance was set at p <or= 0.05. No significant differences were noted among the groups at baseline. The RT group significantly decreased body fat percent from baseline to week 8 and from baseline to week 16, whereas the AT group significantly decreased body fat percent and body mass from baseline to week 16. The RT group significantly improved most musculoskeletal fitness, pain, disability, and QOL outcomes from baseline to week 8, baseline to week 16, and weeks 8 to 16. However, the AT group showed significant improvements in flexibility from baseline to week 8 and in cardiorespiratory and peak leg power from baseline to week 8 and baseline to week 16. The AT groups showed no significant improvements in pain, disability, or QOL. The primary finding was that periodized RT was successful at improving many fitness, pain, disability, and QOL outcome measures, whereas AT was not. This study indicates that whole-body periodized RT can be used by training and conditioning personnel in the rehabilitation of those clients suffering with CLBP.
本研究旨在确定两种不同的阶段性运动康复计划（阻力训练[RT]和有氧训练[AT]）对慢性（≥3个月；≥3天/周）非特异性下腰痛（CLBP）患者肌肉骨骼健康、身体成分、疼痛、残疾状况和生活质量（QOL）的影响。27名CLBP受试者被随机分为3组中的1组，1）RT组（n = 9），2）AT组（n = 9），或3）对照组（C；n = 9）。在基线以及训练的第8周和第16周对受试者进行测试。训练组的强度和训练量进行了阶段性调整。显著性设定为p≤0.05。在基线时，各组之间未观察到显著差异。RT组从基线到第8周以及从基线到第16周，身体脂肪百分比显著降低，而AT组从基线到第16周，身体脂肪百分比和体重显著降低。RT组从基线到第8周、基线到第16周以及第8周到第16周，大多数肌肉骨骼适应性、疼痛、残疾状况和生活质量指标均显著改善。然而，AT组从基线到第8周，柔韧性显著改善，从基线到第8周以及基线到第16周，心肺功能和腿部峰值力量显著改善。AT组在疼痛、残疾状况或生活质量方面没有显著改善。主要发现是，阶段性RT成功改善了许多适应性、疼痛、残疾状况和生活质量指标，而AT则没有。本研究表明，全身阶段性RT可被训练和体能训练人员用于CLBP患者的康复。
