目的：本研究的目的是调查完全无负载屈曲和举重技术下躯干伸展的运动模式，这可以为物理治疗师、脊椎按摩医生和其他手法治疗师提供有价值的信息。方法：采用了参与者内部研究设计。使用 3 维运动分析系统（Vicon Motion Systems）收集 16 名健康男性参与者在举重和躯干完全屈曲期间的全身运动学和动力学数据。为了评估举重和躯干完全屈曲之间关节运动的关系，计算了皮尔逊相关系数。结果：举重试验前半段腰椎伸展角度的变化量与空载躯干屈曲和伸展期间腰椎运动之间没有显着相关性。然而，举重过程中腰椎伸展角度的变化量与无负载躯干屈伸过程中的髋部运动显着负相关（P < .05）。结论：躯干完全屈曲时的最大髋关节屈曲角度对举重过程中腰髋复合体的运动学有较大影响的研究结果为举重过程中人体运动提供了新的见解。所有研究参与者都是健康男性；因此，研究结果仅限于这一群体。
Objectives: The purpose of this study was to investigate between movement patterns of trunk extension from full unloaded flexion and lifting techniques, which could provide valuable information to physical therapists, doctors of chiropractic, and other manual therapists.Methods: A within-participant study design was used. Whole-body kinematic and kinetic data during lifting and full trunk flexion were collected from 16 healthy male participants using a 3-dimensional motion analysis system (Vicon Motion Systems). To evaluate the relationships of joint movement between lifting and full trunk flexion, Pearson correlation coefficients were calculated.Results: There was no significant correlation between the amount of change in the lumbar extension angle during the first half of the lifting trials and lumbar movement during unloaded trunk flexion and extension. However, the amount of change in the lumbar extension angle during lifting was significantly negatively correlated with hip movement during unloaded trunk flexion and extension (P < .05).Conclusions: The findings that the maximum hip flexion angle during full trunk flexion had a greater influence on kinematics of lumbar-hip complex during lifting provides new insight into human movement during lifting. All study participants were healthy men; thus, findings are limited to this group.
