We analyzed the usefulness of a semi-tethered field running test (STR) and the relationships between indices of anaerobic power, anaerobic capacity and running performance in 9 trained male sprinters (22.2 ± 2.9 yrs, 176 ± 1 cm, 68.0 ± 9.4 kg). STR involved an all out 120 m run attached to an apparatus that enabled power calculation from force and velocity measures. Subjects also carried out a cycloergometer Wingate Anaerobic Test (WT), an all out 300 m run and had accessed their maximal accumulated oxygen deficit (MAOD) on a treadmill. Peak and mean powers attained in STR (1720 ± 221 and 1391 ± 201 W) were greater but significantly related (r = 0.82; P < 0.01) to those in the WT (808 ± 130 and 603 ± 87 W). In addition, power measures derived from the STR were stronger related to running performance compared to those from the WT (r = 0.81-0.94 vs. 0.68-0.84; P < 0.05). Relationships between MAOD and most power indices were only weak to moderate. These results support the usefulness of STR for specific power assessment in field running and suggest that anaerobic power and capacity are not related entities, irrespective of having been evaluated using similar or dissimilar exercise modes.
我们分析了半束缚场跑测试（STR）的有用性，以及在 9 名训练有素的男性短跑运动员（22.2 ± 2.9 岁，176 ± 1 厘米，68.0 ± 9.4 公斤）的无氧功率、无氧能力和跑步表现之间的关系。STR 涉及一项全力以赴的 120 米跑，该跑与一个设备相连，该设备可以根据力和速度测量来计算功率。受试者还进行了自行车测功机无氧测试（WT）、全力以赴的 300 米跑，并在跑步机上测量了最大累积氧亏（MAOD）。STR 中达到的峰值和平均功率（1720 ± 221 和 1391 ± 201 W）较高，但与 WT 中的功率（808 ± 130 和 603 ± 87 W）显著相关（r = 0.82；P < 0.01）。此外，与 WT 相比，STR 得出的功率测量与跑步表现的关系更强（r = 0.81-0.94 对 0.68-0.84；P < 0.05）。MAOD 与大多数功率指数之间的关系仅为弱到中度。这些结果支持 STR 在现场跑步中进行特定功率评估的有用性，并表明无氧功率和能力不是相关实体，无论使用相似或不同的运动模式进行评估。
