Body fat estimation of a volleyball player, 1999 to 2018 (Original)

Abstract

The objective of the study was to determine the fat percentage of a volleyball player from 1999 to 2018 (20 years). The intentional sample of the research was composed by a volleyball player of the Marques Junior study (2015). The fat percentage was established through circumference measurements as determined by McArdle, Katch and Katch (2011). Kruskal Wallis ANOVA detected statistical difference of the fat percentage, H (19) = 49, p = 0,0002. The post hoc Dunn identified a statistical difference of the fat percentage in a comparison: 2000 versus 2009, a difference of -48.63. The Kruskal Wallis ANOVA detected a statistical difference in abdominal circumference in centimeters, H (19) = 57.68, p = 0.0001. The post hoc Dunn identified a statistical difference of abdominal circumference in centimeters in four comparisons - 1999 to 2002 versus 2017 and 2018. The new statistic of Cumming (2014) also identified a statistical difference in the same p value. In conclusion, determining the volleyball player's fat percentage is an important measure because the physical trainer prescribes the type of training based on that data to cause an increase in the player's sporting performance.
