本研究旨在探讨相邻跑步者的脚步对主跑者步频、心率及运动量的影响。参与者是属于大学田径队的男子长跑运动员。进行了两个实验，其中主跑步者（参与者）和NR（检查者）以相同的跑步速度在两个由薄壁隔开的相邻跑步机上跑步。参与者被告知，实验目的是调查与他人一起跑步和独自跑步时的HR。在实验1中，NR进行了三次试验，在5 bpm（每分钟心跳）更快（+5bpmFS），5 bpm更慢（-5bpmFS），或没有脚步（NF）的条件下改变脚步克里思。结果表明，足迹条件影响SF的变异性，但不影响平均SF。接下来，通过增加脚步克里思条件来进行实验2。NR进行了7次试验，分别将脚步克里思改变±3 bpm、±5 bpm、±10 bpm或不改变脚步。结果表明，脚步条件影响平均SF，并且与NF相比，SF在-10bpmFS处降低。两种条件下的HR和RPE无差异。这些结果表明，NR的脚步可以影响SF，虽然目前还不清楚脚步是否参与了跑步者之间的同步。总的来说，我们的研究结果强调了影响跑步行为的环境因素，包括NR的脚步声。
This study aimed to investigate the effect of footsteps of a neighboring runner (NR) on the main runner’s step frequency (SF), heart rate (HR), and rating of perceived exertion (RPE). The participants were male long-distance runners belonging to a university track and field team. Two experiments were conducted in which the main runner (participant) and NR (examiner) ran with the same running speed on two adjacent treadmills separated by a thin wall. The participants were instructed that the experimental purpose was to investigate the HR when running with others and running alone. In Experiment 1, NR performed three trials of changing the footstep tempo in 5 bpm (beat per minute) faster (+5bpmFS), 5 bpm slower (-5bpmFS), or no footsteps (NF) conditions. The results showed that the footstep condition affected the variability of the SF but not the mean SF. Next, Experiment 2 was conducted by increasing the footstep tempo condition. NR performed seven trials of changing the footstep tempo by ±3 bpm, ±5 bpm, ±10 bpm, or no footstep. The results showed that the footstep condition affected the mean SF and the SF decreased at -10bpmFS compared to NF. There were no differences in the HR and RPE between conditions. These results indicated that the footsteps of NR could influence the SF, although it was unclear whether footsteps were involved in the synchronization between runners. Overall, our findings emphasize the environmental factors that influence running behavior, including the NR’s footsteps.
