: The purpose of this study was to examine the reliability and validity of the 30-15 Intermittent Field Test (30-15) with and without a ball. : Twenty-four collegiate female soccer players (19.46 ± 1.22 years; 167.01 ± 7.23 cm; 60.95 ± 7.84 kg) performed 1 trial of the Yo-Yo Intermittent Recovery (YYIR) test, 3 trials of the 30-15, and 3 trials of the 30-15 with a ball (30-15), separated by a minimum 48 hours. Maximal intermittent running velocity (V), heart rate at exhaustion (HR), and rating of perceived exertion (RPE) were collected. : Intraclass correlation coefficients (ICCs) between trials demonstrated good reliability during the 30-15 in V (ICC = 0.88) and HR (ICC = 0.89), in addition to the 30-15 V (ICC = 0.83) and HR (ICC = 0.87). V was significantly reduced in 30-15 (15.82 km h) compared to 30-15 (17.52 km h; < .001), regardless of trial. HR and RPE were significantly greater in 30-15 compared to 30-15 ( < .05). Estimated maximal oxygen consumption (VOmax) YYIR and estimated VOmax of 30-15 and 30-15 was very strongly ( = 0.82) and strongly ( = 0.68) correlated. : The 30-15 is considered valid and reliable and the 30-15 was reliable in female soccer players.
: 本研究旨在检验有球和无球情况下 30-15 间歇性场内测试（30-15）的可靠性和有效性。 : 24 名大学女子足球运动员（19.46 ± 1.22 岁；167.01 ± 7.23 厘米；60.95 ± 7.84 公斤）进行了 1 次 Yo-Yo 间歇性恢复测试（YYIR）、3 次 30-15 测试和 3 次 30-15 带球测试（30-15），两次测试之间至少间隔 48 小时。收集了最大间歇性跑动速度（V）、力竭时的心率（HR）和感知用力程度（RPE）。 : 试验间的组内相关系数（ICC）表明，在 30-15 的 V（ICC = 0.88）和 HR（ICC = 0.89）以及 30-15 的 V（ICC = 0.83）和 HR（ICC = 0.87）方面具有良好的可靠性。与 30-15（17.52 公里/小时）相比，30-15（15.82 公里/小时）的 V 明显降低（<0.001），且无论试验如何。与 30-15 相比，HR 和 RPE 在 30-15 中显著更高（<0.05）。YYIR 的最大估计耗氧量（VOmax）和 30-15 和 30-15 的估计 VOmax 具有非常强的相关性（= 0.82）和强相关性（= 0.68）。 : 30-15 被认为是有效和可靠的，而在女子足球运动员中，30-15 是可靠的。
