与传统椅子相比,积极坐椅每15分钟能耗增加1.5千卡. 这一发现表明,运动椅是减少久坐行为和在工作站促进新陈代谢的可行选择.
科学领域:
- 职业健康 职业健康 职业健康
- 人体工程学就是人体工程学.
- 人体生理学 人体生理学
背景情况:
- 工作场所的久坐不动行为越来越令人担忧.
- 积极的坐椅被提出作为减轻久坐行为的解决方案.
- 这项研究研究了活跃的坐椅对生理的影响.
研究的目的:
- 为了评估一个活跃的坐着的椅子对电脑工作期间的能源消耗的影响.
- 为了比较活跃的坐椅和传统的办公椅之间的生理反应.
- 评估不同类型的椅子之间代谢和心脏变量的差异.
主要方法:
- 一项涉及16名参与者 (8名男性,8名女性) 的横截面研究.
- 参与者完成了两次20分钟的标准化计算机工作会议,一个是在积极的坐椅上,一个在传统的办公椅上.
- 用代谢车和Hexoskin衫测量了新陈代谢,呼吸和心脏变量.
主要成果:
- 活动式坐椅显著增加了7.6% (0.02L/分钟) 的氧气吸收 (V ̇O2).
- 这与传统的椅子相比,每15分钟能耗增加1.5千卡.
- 观察到分钟通风率 (V ̇E),心率 (HR) 的显著增加,心率变化率 (HRV) 的下降.
结论:
- 活动式坐椅增加了能量消耗,相当于每小时6千卡或每天48千卡.
- 热量消耗相当于爬楼梯或使用其他替代工作站.
- 带有多轴旋转座椅板的活式坐椅提供了一种可行的方法来增加工作站的能源消耗.
