BACKGROUND
Isokinetic training (IKT) and core stabilization training (CST) are commonly used for balance training in musculoskeletal conditions. The knowledge about the effective implementation of these training protocols on radiological and biochemical effects in university football players with chronic low back pain (LBP) is lacking.
OBJECTIVE
To find and compare the effects of isokinetic training and CST on radiological and biochemical effects in university football players with chronic LBP.
DESIGN
Randomized, double-blinded controlled study.
SETTING
University hospital.
PARTICIPANTS
60 LBP participants were randomized into isokinetic group (IKT; n = 20), core stabilization group (CST; n = 20) and the control group (n = 20) and received respective exercises for 4 weeks.
OUTCOME MEASURES
Radiological (muscle cross sectional area & muscle thickness) and biochemical (C-reactive protein, tumor necrosis factor -α, interleukin [IL]-2, IL-4, IL-6) values were measured at baseline and after 4 weeks (immediate effect).
RESULTS
The reports of the IKT, CST and control group were compared between the groups. Four weeks following training IKT group shows more significant changes in muscle cross sectional area (Psoas Major, Quadratus Lumborum, Multifidus and Erector Spinae muscles) and muscle thickness (Multifidus) than CST and control groups (p < 0.001). Biochemical measures such as C-reactive protein, tumor necrosis factor -α, IL-2, IL-4 and IL-6 also show significant improvement in IKT group than the other 2 groups (P < .001).
CONCLUSION
Training through Isokinetic is an effective treatment program than conventional exercise programs in the aspect of radiological and biochemical analysis in university football players with chronic LBP, which may also help to prevent further injury. The present study can be used to improve the physical therapist's knowledge and clinical decision skills on LBP in football players.
背景
等速训练（IKT）和核心稳定性训练（CST）常用于肌肉骨骼疾病的平衡训练。在患有慢性下腰痛（LBP）的大学生足球运动员中，关于这些训练方案对影像学和生物化学影响的有效实施的知识还很缺乏。
目的
比较等速训练和 CST 对患有慢性 LBP 的大学生足球运动员的影像学和生物化学影响。
设计
随机、双盲对照研究。
地点
大学医院。
参与者
60 名慢性 LBP 参与者被随机分为等速训练组（IKT；n=20）、核心稳定性训练组（CST；n=20）和对照组（n=20），并分别接受 4 周的相应训练。
观察指标
影像学（肌肉横截面积和肌肉厚度）和生物化学指标（C 反应蛋白、肿瘤坏死因子-α、白细胞介素[IL]-2、IL-4、IL-6）在基线和 4 周后（即刻效应）进行测量。
结果
比较了 IKT、CST 和对照组的报告。训练 4 周后，IKT 组的竖脊肌、多裂肌、腰方肌和腹直肌的肌肉横截面积和多裂肌的肌肉厚度变化明显大于 CST 组和对照组（P<0.001）。C 反应蛋白、肿瘤坏死因子-α、IL-2、IL-4 和 IL-6 等生化指标也显示 IKT 组比其他两组有明显改善（P<0.001）。
结论
与传统运动方案相比，IKT 训练是治疗患有慢性 LBP 的大学生足球运动员的有效方案，这也可能有助于预防进一步受伤。本研究可以提高物理治疗师在足球运动员 LBP 方面的知识和临床决策技能。
