摘要

背景:膝关节伸展运动对肥胖和超重者是有用和实用的,因为这种形式的运动可以有效地减少关节的体重负荷,改善身体的生理功能。本研究旨在比较办公室工作人员在装有主动脚踏板(AFR)原型机的活动工作站上进行坐姿膝关节伸展运动时的生理和心理物理参数,以及比较正常体重和肥胖办公室工作人员的生理和心理物理参数。方法:在准实验研究中,对32名28 ~ 50岁上班族(M = 42.72,标准差[SD] = 4.37)在坐式和活动式工作站(配备AFR)执行办公任务时的心率(HR)和能量消耗(EE)生理参数(使用Fitbit Charge HR智能手表测量)进行两次交叉随机测试,其中16名体重正常,16名肥胖。感知体力消耗、舒适度、疲劳度和喜爱度也通过给参与者打分来衡量。研究结果:与坐着工作的参与者相比,AFR参与者在执行计算机任务时的短期活动显著改善了生理和心理物理参数。然而,在正常体重和肥胖参与者之间,AFR对生理和心理物理参数的影响没有显著差异。结论/在实践中的应用:考虑到与传统工作站相比,使用AFR运动导致的情感表达和人力资源显著增加,使用AFR可以帮助上班族在工作场所达到最低的身体活动标准。

Knee Extension Exercise Effects on Physiological and Psychophysical Performance: Normal Weight Versus Obese Office Workers.

Background: Knee extension exercise is useful and practical for obese and overweight people as this form of exercise is effective in minimizing body weight loading on joints and improving the body's physiological function. This study aimed to compare the physiological and psychophysical parameters of office workers while computer-based working in an active workstation equipped with an active footrest (AFR) prototype with a mechanism for performing knee extension exercises in a sitting position, and also to compare the physiological and psychophysical parameters among normal-weight and obese office workers.

Methods: In this quasi-experimental study, the physiological parameters of heart rate (HR) and energy expenditure (EE) (measured with the Fitbit Charge HR smartwatch) were measured in two cross-over random sessions for 32 office workers (16 normal-weight and 16 obese) aged 28 to 50 years (M = 42.72, standard deviation [SD] = 4.37) while performing office tasks in sitting and active workstations (equipped with AFR). Perceived physical exertion, comfort, fatigue, and liking were also measured by rating the participants.

Findings: Short-term activity of the participants with AFR performing computer tasks significantly improved physiological and psychophysical parameters compared with the participants in sitting workstations. However, there was no significant difference in the effect of AFR on physiological and psychophysical parameters between normal-weight and obese participants.

Conclusions/application to practice: Given the significant increase in EE and HR resulting from exercise with AFR compared with the conventional workstation, the use of AFR can help office workers achieve the minimum standard of physical activity at their workplace.
