摘要跑步场地测试是用来评估运动员体能水平的一种高特异性测试。然而，在分级运动测试中，缺乏速度控制会导致不均匀的步伐，降低可重复性和准确性。本研究的目的是开发反馈变量（FV），并调查其对运动员保持速度恒定的能力的影响。48名参与者在4种步速（7.5 - 10 km·h-1）下完成了4次Conconi测试（随机）。一款智能手机应用程序为运动员提供了四种FV：经典、声音（口头）、振动和声音与振动。我们发现，FV对依从性（定义为在目标速度0.3 km·h−1以内的时间）有显著影响：F（3，141）= 41.45，p <0.001，η2 = 0.268。经典（M± SD）的依从性为39.51 ± 13.51%，显著低于（p < .001）振动（53.24 ± 14.98%）、声音（60.34 ± 11.21%）和声音与振动（59.17 ± 15.17%）。与传统方法相比，新型FV提供了更好的粘附性，其中声音和声音与振动显示出最高的粘附性。通常，新型FV具有易于实现和减少设置、数据收集和处理所需时间的优点，因此证明在进行现场性能测试中是有用的。
ABSTRACT Running field tests are utilised to assess the athlete’s fitness level with high specificity. However, in graded exercise tests the lack of speed control can result in an uneven pace, reducing reproducibility and accuracy. The purpose of this study was to develop feedback variants (FV) and investigate their effect on the athlete’s ability to keep the pace constant. Forty-eight participants completed four trials of a Conconi test (randomised) over four paces (7.5 − 10 km·h−1). A smartphone app provided athletes with four FVs: Classic, Sound (verbal), Vibration, and Sound & Vibration. We found a significant effect of FV on adherence (defined as time within 0.3 km·h−1 of target speed): F(3,141) = 41.45, p < .001, η2 = .268. Adherence in Classic (M± SD) 39.51 ± 13.51% was significantly lower (p < .001) than in Vibration (53.24 ± 14.98%), Sound (60.34 ± 11.21%) and Sound & Vibration (59.17 ± 15.17%). The novel FV provided better adherence compared to the conventional method, with Sound and Sound & Vibration showing the highest adherence. Generally, the novel FVs have the advantage of being easily implemented and decreasing the required time for setup, data collection and processing, therefore proving useful in conducting field performance tests.
