目的：检验30-15(IFT)量表在竞技女足运动员中的信度、效度和效度。采用受试者内测验-重测研究设计来评估30-15间歇适能测验(IFT)的可靠性。在30-15(IFT)之前7天。受试者在实验室条件下进行连续有氧跑步试验(CT)，以评估30-15(IFT)的标准效度。结果：30~15次(IFT)的V-IFT(ICC=0.91；CV=1.8%)、HRPeak(ICC=0.94；CV=1.2%)和VO2max(ICC=0.94；CV=1.6%)均具有较高的可靠性(P&gT；0.05)。30-15(IFT)与CT的VO2max、HR峰值和终点速度的皮尔逊积矩相关系数分别为0.67(p=0.013)、极大(r=0.77，p=0.02)和(r=0.57，p=0.042)。这些发现还为从业者提供了证据，支持准确检测0.5公里/小时(1级)的VIFT和2次/分的心率峰值的有意义的个体变化。这些信息可以帮助教练员监测“真正的”有氧体能变化，以便更好地为女子间歇性团队运动运动员的训练提供信息。最后，教练员可以使用30-15(IFT)作为基于实验室评估的实用替代方案，以评估和监测运动员的间歇性有氧适应变化。
PURPOSE: The aim of this study was to examine the reliability, validity and usefulness of the 30-15(IFT) in competitive female soccer players.METHODS: Seventeen elite female soccer players participated in the study. A within subject test-retest study design was utilized to assess the reliability of the 30-15 intermittent fitness test (IFT). Seven days prior to 30-15(IFT). subjects performed a continuous aerobic running test (CT) under laboratory conditions to assess the criterion validity of the 30-15(IFT). End running velocity (V-CT and V-IFT), peak heart rate (HRpeak) and maximal oxygen consumption (VO2max) were collected and/or estimated for both tests.RESULTS: V-IFT (ICC = 0.91; CV = 1.8%), HRpeak (ICC = 0.94; CV = 1.2%), and VO2max (ICC = 0.94; CV = 1.6%) obtained from the 30-15(IFT) were all deemed highly reliable (p > 0.05). Pearson product moment correlations between the CT and 30-15(IFT) for VO2max, HRpeak and end running velocity were large (r = 0.67, p = 0.013), very large (r = 0.77, p = 0.02) and large (r = 0.57, p = 0.042), respectively.CONCLUSION: Current findings suggest that the 30-15(IFT) is a valid and reliable intermittent aerobic fitness test of elite female soccer players. The findings have also provided practitioners with evidence to support the accurate detection of meaningful individual changes in VIFT of 0.5 km/h (1 stage) and HRpeak of 2 bpm. This information may assist coaches in monitoring "real" aerobic fitness changes to better inform training of female intermittent team sport athletes. Lastly, coaches could use the 30-15(IFT) as a practical alternative to laboratory based assessments to assess and monitor intermittent aerobic fitness changes in their athletes.
