To analyze progression of changes in kinematics and work physiology during progressive lifting in healthy adults.
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.
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.
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.
分析健康成年人在渐进式举重过程中运动学和工作生理学变化的进展。
招募健康参与者。进行了 WorkWell 功能能力评估 (FCE) 的标准化举重测试，包括五个渐进式举重低系列，每个系列重复五次。研究了 WorkWell 观察方案的标准：肌肉使用变化（肌电图）、心率（心率监测器）、支撑基础、姿势和运动模式（运动捕捉系统）。使用重复测量方差分析来分析渐进式工作负荷期间的变化。
18 名健康年轻成年人参与（8 名男性，10 名女性；平均年龄 22 岁）。男性和女性的最大平均举重重量分别为 66（±3.2）和 44（±7.4）kg。随着负荷的增加，观察到统计学上显著（p<0.01）的差异：中度举重时次要肌肉使用增加、心率增加、支撑基础增加和运动模式变化；姿势差异不显著。
使用实验室技术，在健康成年人的渐进式举重过程中，客观地量化了 5 个运动学和工作生理学参数中的 4 个参数的变化。这些变化似乎符合现有的观察标准。
