我们调查了在最近验证的短跑跑步机上进行的100 m短跑与在标准跑道上进行的100 m短跑之间的表现差异。到目前为止，比较地上跑和跑步机跑的研究主要集中在恒定的而不是最大的“自由”跑速度上，并在有限的步数上比较跑步动力学和运动学，但不是整体短跑表现。11名男性体育教育的学生，包括两名短跑运动员进行了一个100米的跑步机和一个标准的田径跑道上的随机顺序，分开30分钟。性能数据来自在这两种情况下，从测量与雷达和仪表短跑跑步机，它允许受试者运行和生产速度“自由”，即没有预定的皮带速度施加速度的速度-时间关系。采用t检验比较了运动场和跑台的典型速度-距离曲线、最大速度和平均速度、100 m时间和加减速时间常数，并检验了运动场-跑台的相关性。除达到最高速度的时间和减速时间常数外，所有性能参数在场地和跑步机之间均存在显著差异，平均差异约为20%（例如，最高速度为8.84 +/- A 0.51 vs 6.90 +/- A 0.39 m s（-1））。除达到最高速度的时间外，其余各项指标均呈显著相关（r > 0.63; P < 0.05）。跑步机和100米短跑的表现是不同的，尽管事实上，受试者可以自由地加速带。然而，显着的相关性发现，使人们有可能调查和解释个体间的差异，从跑步机的测量领域的表现。
We investigated the differences in performance between 100-m sprints performed on a sprint treadmill recently validated versus on a standard track. To date, studies comparing overground and treadmill running have mainly focused on constant and not maximal "free" running speed, and compared running kinetics and kinematics over a limited number of steps, but not overall sprint performance. Eleven male physical education students including two sprinters performed one 100-m on the treadmill and one on a standard athletics track in a randomized order, separated by 30 min. Performance data were derived in both cases from speed-time relationships measured with a radar and with the instrumented sprint treadmill, which allowed subjects to run and produce speed "freely", i.e. with no predetermined belt speed imposed. Field and treadmill typical speed-distance curves and data of maximal and mean speed, 100-m time and acceleration/deceleration time constants were compared using t tests and field-treadmill correlations were tested. All the performance parameters but time to reach top speed and deceleration time constant differed significantly, by about 20% on average, between field and treadmill (e.g. top speed of 8.84 +/- A 0.51 vs. 6.90 +/- A 0.39 m s(-1)). However, significant correlations were found (r > 0.63; P < 0.05) for all the performance parameters except time to reach top speed. Treadmill and field 100-m sprint performances are different, despite the fact that subjects could freely accelerate the belt. However, the significant correlations found make it possible to investigate and interpret inter-individual differences in field performance from treadmill measurements.
