The Cooper Institute established new criterion-referenced standards for the body composition and cardiovascular fitness standards for the FITNESSGRAM(®) program.
The purpose of this study was to evaluate differences in the achievement of standards and classification agreement between the old and new standards.
Fitness data were collected during the 2009-2010 school year from 1686 youth (grades 3-12) from six schools (two districts) in a small Midwestern town. Data analyses were completed during the 2010 and 2011 school year. Descriptive statistics were computed to determine the percentage of students classified into the various fitness classifications using both the old and new standards. Classification agreement was examined for alternative tests of cardiovascular fitness (Progressive Aerobic Cardiovascular Endurance Run [PACER] and 1-mile run) and body composition (skinfold determination of body fat and BMI) using both the old and new standards.
The descriptive results reveal important age and gender differences in reported levels of fitness levels in school-aged youth. For body composition, the percentage of youth achieving the healthy fitness zone (HFZ) was about 10% lower with the new standards than the old ones. For aerobic capacity, a larger percentage of young boys and a smaller percentage of older boys achieved the new HFZ for aerobic capacity. However, a smaller percentage of girls achieved the new HFZ at all ages. The use of test-equating in the revised standards led to significant improvements in the classification agreement between 1-mile run and the PACER.
The large data set provided a useful sample to examine the impact of the new fitness standards on the documentation of youth fitness levels in schools. The new standards address a number of measurement issues with the old standards and provide a more appropriate way to evaluate levels of health-related fitness in youth.
库珀研究所（Cooper Institute）为 FITNESSGRAM（®）计划的身体成分和心血管健康标准制定了新的参考标准。
本研究旨在评估新标准和旧标准在达标情况和分类一致性方面的差异。
在 2009-2010 学年，从一个中西部小镇的六所学校（两个区）收集了 1686 名青少年（3-12 年级）的健身数据。数据分析于 2010 年和 2011 年学年进行。使用旧标准和新标准计算了不同健身分类的学生比例的描述性统计数据。使用旧标准和新标准对替代心血管健康测试（渐进式有氧运动心血管耐力跑[PACER]和 1 英里跑）和身体成分（体脂皮褶测定和 BMI）进行了分类一致性检验。
描述性结果揭示了不同年龄段和性别的青少年在报告的健身水平方面的重要差异。在身体成分方面，新的标准下，达到健康健身区（HFZ）的青少年比例比旧标准低约 10%。在有氧能力方面，更多的年轻男孩和较少的年长男孩达到了新的有氧能力 HFZ。然而，所有年龄段的女孩达到新 HFZ 的比例都较小。在修订标准中使用测试等效性导致了 1 英里跑和 PACER 之间的分类一致性的显著提高。
大量数据集为检查新标准对学校青少年健身水平记录的影响提供了有用的样本。新标准解决了旧标准的一些测量问题，并为评估青少年健康相关健身水平提供了更合适的方法。
