: This study evaluated participants' ability to assemble a computer keyboard while at a cycling workstation. Depending on task completion time, error percentage, and workload based on subjective workload ratings, subjective body discomfort, electroencephalography (EEG) and electrocardiographic (ECG) signals, human performances were compared at four different cycling conditions: no cycling, low level cycling (15 km/h), preferred level cycling, and high level cycling (25 km/h). The experiment consisted of 16 participants. Each participant performed the test four times (each cycling condition) on different days. : The repeated measure test showed that the alpha and beta EEG signals were high during session times (post) when compared with session times (pre). Moreover, the mean interbeat (R-R) interval decreased after the participants performed the assembly while pedaling, possibly due to the physical effort of cycling. : Pedaling had no significant effect on body discomfort ratings, task errors, or completion time.
: 本研究评估了参与者在自行车工作站上组装计算机键盘的能力。根据任务完成时间、错误百分比以及基于主观工作负荷评定、主观身体不适、脑电图 (EEG) 和心电图 (ECG) 信号的工作负荷，在四种不同的骑行条件下比较了人类表现：不骑行、低水平骑行（15 公里/小时）、偏好水平骑行和高水平骑行（25 公里/小时）。实验由 16 名参与者组成。每位参与者在不同的日子里四次完成测试（每种骑行条件一次）。 : 重复测量检验表明，与时段（前）相比，时段（后）的α和β脑电信号较高。此外，参与者在踩踏时进行组装后，平均心搏（R-R）间隔缩短，这可能是由于骑行的体力消耗所致。 : 踩踏对身体不适评分、任务错误或完成时间没有显著影响。
