Purpose

To analyze progression of changes in kinematics and work physiology during progressive lifting in healthy adults.

Methods

Healthy participants were recruited. A standardized lifting test from the WorkWell Functional Capacity Evaluation (FCE) was administered, with five progressive lifting low series of five repetitions. The criteria of the WorkWell observation protocol were studied: changes in muscle use (EMG), heart rate (heart rate monitor), base of support, posture and movement pattern (motion capture system). Repeated measures ANOVA's were used to analyze changes during progressive workloads.

Results

18 healthy young adults participated (8 men, 10 women; mean age 22 years). Mean maximum weight lifted was 66 (±3.2) and 44 (±7.4) kg for men and women, respectively. With progressive loads, statistically significant (p < 0.01) differences were observed: increase in secondary muscle use at moderate lifting, increase of heart rate, increase of base of support and movement pattern changes were observed; differences in posture were not significant.

Conclusions

Changes in 4 out of 5 kinematic and work physiology parameters were objectively quantified using lab technology during progressive lifting in healthy adults. These changes appear in line with existing observation criteria.

健康成人渐进式提升过程中运动学和工作生理学的变化

目的

分析健康成人在渐进式举重过程中运动学和工作生理学变化的进展。

方法

招募了健康的参与者。进行了来自 WorkWell 功能能力评估 (FCE) 的标准化举重测试，其中包括五个渐进式举重低系列，每组重复五次。研究了 WorkWell 观察协议的标准：肌肉使用 (EMG)、心率（心率监测器）、支撑基础、姿势和运动模式（动作捕捉系统）的变化。重复测量方差分析用于分析渐进式工作负载期间的变化。

结果

18 名健康的年轻人参加了（8 名男性，10 名女性；平均年龄 22 岁）。男性和女性的平均最大举重分别为 66 (±3.2) 和 44 (±7.4) 公斤。随着负荷的增加，观察到统计学上显着的差异（p < 0.01）：观察到中度提升时二级肌肉使用增加、心率增加、支撑基础增加和运动模式变化；姿势差异不显着。

结论

在健康成人的渐进式举重过程中，使用实验室技术客观地量化了 5 个运动学和工作生理学参数中的 4 个的变化。这些变化符合现有的观察标准。
