Abstract:BACKGROUND: An understanding of the reproducibility of body composition measurements is essential for effective intervention studies. Air displacement plethysmography (ADP) and bioelectrical impedance (BIA) are two easy-to-use measures of body composition. The present study aimed to assess the reproducibility of ADP and BIA and compare them with each other, as well as with skinfold measurement. METHODS: Forty-one participants were tested on two occasions following an overnight fast. On test day 1, participants' height, weight and % body fat (BF) were measured using ADP and BIA. Measurements were replicated to assess the within-day reproducibility. On test day 2, participants were again tested using ADP and BIA and had skinfold measurements taken. Three skinfold equations for BF calculation were applied. Comparisons of within- and between-day reproducibility and between measurement techniques were completed using Pearson correlations and Bland-Altman analysis. RESULTS: Both Pearson correlation and Bland-Altman analysis showed good within- and between-day relationships and agreement for BF from ADP and BIA measurements. The two methods had a high correlation between them; however, the mean difference between the two was 3.1% (4.1%). From the skinfold equations used, the best agreement with ADP had a mean difference of 0.3% (0.8%) and, with BIA, had mean differences of 1.9% (4.2%). CONCLUSIONS: The data indicate that ADP and BIA cannot be used interchangeably, although both measurements had good within- and between-day agreement.
