This study evaluated the use of a new primary field test method based on test equating to address inconsistent classification among field tests. We analyzed students' information on the Progressive Aerobic Cardiovascular Endurance Run (PACER), mile run (MR), and VO2max from three data sets (college: n = 94; middle school: n = 39; elementary school: n = 96). Using the college and elementary school data, the equivalent relationship between PACER and MR scores was first established by the Kernel equating method. This yielded MR scores derived from PACER (mile run PACER equated [MR PEQ]), which were used to predict maximal oxygen uptake (VO2max) and classify students according to the FITNESSGRAM Healthy Fitness Zones. We compared the results to the predictions and classifications based on measured VO2max, MR and PACER-predicted VO2max and cross-validated the relationships using the middle school data. We found the test conversion to be accurate and that the MR PEQ scores functioned similarly to the original MR scores. Both performed better than the original PACER scores in predicting VO2max and classifying students. The middle school data generally supported these results. The proposed method is accurate and effective in setting a new field test onto the same scale of a primary field test and determining its cut-off scores.
本研究评估了一种新的基于测试等效的主要现场测试方法的使用,以解决现场测试之间不一致的分类问题。我们分析了来自三个数据集(学院:n = 94;中学:n = 39;小学:n = 96)的学生在渐进式有氧运动心血管耐力跑(PACER)、英里跑(MR)和最大摄氧量(VO2max)方面的信息。使用学院和小学数据,首先通过核等方法建立 PACER 和 MR 分数的等效关系。由此产生的从 PACER 得出的 MR 分数(英里跑 PACER 等效 [MR PEQ])用于预测最大摄氧量(VO2max),并根据 FITNESSGRAM 健康健身区对学生进行分类。我们将结果与基于实测 VO2max、MR 和 PACER 预测 VO2max 的预测和分类进行了比较,并使用中学数据对关系进行了交叉验证。我们发现测试转换是准确的,MR PEQ 分数的功能与原始 MR 分数相似。在预测 VO2max 和对学生进行分类方面,两者都优于原始 PACER 分数。中学数据通常支持这些结果。该方法在将新的现场测试设置到主要现场测试的相同量表上并确定其截止分数方面是准确和有效的。
