(P32-003-23) Comparison of Body Fat Percentage Values Measured by Air Displacement Plethysmography (ADP) and Bioelectrical Impedance Analysis (BIA) in Male Volleyball Players

Objectives: Optimal body fat percentage and non-fat body mass differ according to the sports branch, and it plays a vital role in sports performance. In order to preserve the health of athletes and improve their sports performance, the body composition of athletes should be evaluated accurately. This study aims to compare the body fat percentage values measured by Air Displacement Plethysmography (ADP) and Bioelectrical Impedance Analysis (BIA) in male volleyball players.

Methods: Totally, 42 male elite volleyball players were included in this study, with a mean age of 20,50± 3.118, mean weight of 81.27±12.47 and mean height of 185.571±8.58. Subsequent to providing proper conditions, the body compositions of the athletes were measured by the ADP method and BIA equipment. SPSS 20.0 was used for the statistical analysis of the data. The Bland Altman plot was performed to determine mean bias and limits of agreement between BIA body fat percentage and body fat percentage results of ADP. The intra-class correlation coefficient (ICC) was calculated to determine the agreement between measured and predicted RMRs. ICC results were interpreted as poor (below 0.5), moderate (0.50-0.75), good (0.75-0.90) and high (0.90 or higher). The statistical significance level was accepted as p< 0.05.

Results: There was a low bias and no statistically significant difference between the body fat percentages measured by ADP and BIA (p >0.05). Also, the ICC value was 0.78 between BOD-POD and BIA, a high agreement was found, and the confidence interval was 0.598-0.884.

Conclusions: The results suggest the use of the BIA method as a valid and accurate alternative to ADP for the measurement of body fat percentage in male volleyball players.
