Abstract

Objective: The purpose of this study was to examine the reliability and validity of the 30-15 Intermittent Field Test (30-15_IFT) with and without a ball. Methods: 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_IFT, and 3 trials of the 30-15_IFT with a ball (30-15_IFT-B), separated by a minimum 48 hours. Maximal intermittent running velocity (V_IFT), heart rate at exhaustion (HR_peak), and rating of perceived exertion (RPE) were collected. Results: Intraclass correlation coefficients (ICCs) between trials demonstrated good reliability during the 30-15_IFT in V_IFT (ICC = 0.88) and HR_peak (ICC = 0.89), in addition to the 30-15_IFT-B V_IFT (ICC = 0.83) and HR_peak (ICC = 0.87). V_IFT was significantly reduced in 30-15_IFT-B (15.82 km h^-1) compared to 30-15_IFT (17.52 km h^-1; p < .001), regardless of trial. HR and RPE were significantly greater in 30-15_IFT compared to 30-15_IFT-B (p < .05). Estimated maximal oxygen consumption (VO₂max) YYIR and estimated VO₂max of 30-15_IFT and 30-15_IFT-B was very strongly (r = 0.82) and strongly (r = 0.68) correlated. Conclusion: The 30-15_IFT is considered valid and reliable and the 30-15_IFT-B was reliable in female soccer players.

30-15间歇场地测试的信度和效度。

目的:本研究的目的是检验30-15间歇场测试(30-15IFT)的信度和效度，有无球。方法:24名女大学生足球运动员(19.46±1.22岁;167.01±7.23 cm;(60.95±7.84 kg)进行1次溜溜球间歇恢复(YYIR)试验，3次30-15IFT试验，3次30-15IFT带球试验(30-15IFT- b)，间隔至少48小时。收集最大间歇跑步速度(VIFT)、衰竭心率(HRpeak)和感知运动评分(RPE)。结果:除了30-15IFT- b VIFT (ICC = 0.83)和HRpeak (ICC = 0.87)外，试验间的类内相关系数(ICC)在30-15IFT期间的VIFT (ICC = 0.88)和HRpeak (ICC = 0.89)中表现出良好的可靠性。与30-15IFT (17.52 km h-1)相比，30-15IFT- b (15.82 km h-1)显著降低了VIFT;P < 0.001)，与试验无关。30-15IFT组HR和RPE显著高于30-15IFT- b组(p < 0.05)。估计的最大耗氧量(VO2max) YYIR与30-15IFT和30-15IFT- b的估计VO2max非常强(r = 0.82)和强(r = 0.68)相关。结论:30-15IFT量表在女足运动员中是有效可靠的，30-15IFT- b量表是可靠的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
