Abstract

Distracted biking can have serious repercussions for the rider such as accidents. The purpose of the present experiment was to determine the effect of visually monitoring two parameters, the cadence, and the heart rate on a bike computer fixed on a racing bike, and simultaneously detect hazardous traffic situations. Individuals (n = 20) were instructed to ride a racing bike that was fitted onto a roller trainer. After conducting a bicycle step test to assess the maximal heart rate (HF_max), participants were assigned to a within subject-design on a separate day. They were instructed to perform the riding task in two single-task conditions (only watching the traffic at the video with occluded or without occluded bike computer), two multi-tasking conditions (monitoring the cadence of 70 RPM or 90 RPM, monitoring the heart rate, and observing the traffic) and one control condition (no instructions). Percentage dwell time of the eye movements, the constant error from the target cadence, keeping the heart rate in an interval of 50% - 70% of the HF_max, and percentage of the recognized hazard traffic situations were analyzed. The analysis indicated that monitoring the parameters on the bike computer induced no significant decline in perceived hazardous traffic situations.

多任务情况下竞速自行车运动员的视觉行为

骑车分心会给骑车者带来严重后果，如发生事故。本实验的目的是确定通过固定在赛车上的自行车电脑目视监测两个参数（步频和心率）的效果，并同时检测危险的交通状况。实验人员（n = 20）在指导下骑上安装在滚轴训练器上的赛车。在进行自行车台阶测试以评估最大心率（HFmax）后，参与者被分配到另一天的受试者内设计中。他们在两种单一任务条件下（只观察视频中的交通情况，并遮挡或不遮挡自行车电脑）、两种多任务条件下（监测 70 RPM 或 90 RPM 的步频、监测心率并观察交通情况）和一种对照条件下（无指导）完成骑行任务。对眼球运动的停留时间百分比、与目标速度的恒定误差、将心率保持在最高心率的 50%-70%之间以及识别危险交通状况的百分比进行了分析。分析结果表明，监控自行车电脑上的参数并不会导致感知到的危险交通状况显著下降。

期刊介绍： Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
