The aim of this study was to investigate the perception of vibrotactile signals during physical exercise by comparing differences in recognition between stationary and cycling positions. The impact of physical exercise on the ability to perceive vibrotactile cues is unknown, whereas the recognition in stationary position has been shown previously. Vibrating elements were positioned at 3 locations on the thighs and spine of 9 athletes to apply various vibrotactile cues. Subjects performed at 0, 50, 70 and 90% of their maximal cycling power output and denoted the interpretation of the vibration signals on a touchscreen. The results show a similarity in correct recognition between stationary position and physical exercise for the thighs and spine (p>0.1) and demonstrate a decrease in response time for 70 and 90% levels of physical exercise compared to 0 and 50% (p<0.001). Furthermore, vibrotactile signals at the spine are noticed more accurately and more rapidly compared to the thighs (p<0.01). These results suggest that vibrotactile feedback also has potential in applications during physical exercise. The potential use of vibrotactile feedback can be in cycling for, among other, correcting the aerodynamic position. Applications in other sports and health-related domains are feasible as well.
本研究旨在通过比较静止和骑行两种姿势下对振动触觉信号识别的差异，来探究运动员在运动过程中对振动触觉信号的感知。尽管先前已经证实了在静止姿势下对振动触觉信号的识别能力，但运动对感知振动触觉 cue 的能力的影响尚未可知。研究将振动元件放置在 9 名运动员的大腿和脊柱的 3 个位置，以施加不同的振动触觉 cue。被试者以 0%、50%、70%和 90%的最大骑行功率输出进行运动，并在触摸屏上对振动信号的解释进行标注。结果表明，大腿和脊柱的静止位置和运动时的正确识别率相似（p＞0.1），与 0%和 50%相比，70%和 90%的运动水平下的反应时间更短（p＜0.001）。此外，与大腿相比，脊柱上的振动触觉信号被感知得更准确、更快（p＜0.01）。这些结果表明，振动触觉反馈在运动过程中也具有潜在的应用价值。振动触觉反馈的潜在用途可以是在骑行中，例如纠正空气动力学姿势。在其他运动和与健康相关的领域也具有可行性。
