Abstract

BACKGROUND: FITNESSGRAM recommends the use of the PACER, a 20-meter shuttle run, to assess the aerobic ability of children in physical education classes.

OBJECTIVES: To examine the reliability and validity of the PACER for 3rd and 4th grade males. In addition, the reliability and validity of the criterion-referenced standards will be examined.

METHODS: 22 students ran 3 trials of the FITNESSGRAM PACER while wearing the Cosmed K4b2 system.

RESULTS: From the 22 students, the intraclass correlation for the number of laps for trial 2 to trial 3 was 0.81. The reliability of the estimated VO2 from trial 2 to trial 3 was 0 83. For validity, the correlation for the estimated V02 max to peak V02 from the Cosmed was 0.42 for trial 2. For trial 3, the correlation was 0.60. The correlation between laps and peak V02 was 0.57 for trial 2. For trial 3, the correlation was 0.69. The consistency of the classification for the criterion-referenced standards was 0.91 with a modified kappa of 0.85. The accuracy of the classification for the criterion-referenced standards for trial 2 was 0.59. For trial 3, the proportion of agreement was 0.68.

CONCLUSION: The criterion-referenced standards consistently classifies the participants, however, the validity of the classification is low. Peak V02 scores and the estimated V02 did not appear to be highly related. However, the PACER has a high test-rest reliability for males ages 8-10 years.
