Influence of Biological Maturation Status on Kinanthropometric Characteristics, Physical Fitness and Diet in Adolescent Male Handball Players

Abstract

The aims of this research were to analyze the differences in kinanthropometric characteristics and physical performance as a function of biological maturation, as well as to analyze these differences with the inclusion of the covariates age, maturity offset and diet, and to know how the players were classified according to BMI z-score. Seventy-three handball players (mean age: 14.17 ± 0.61) underwent a kinanthropometric assessment, physical performance tests and self-completed the KIDMED questionnaire. The sample was divided into three groups based on age at peak height velocity (APHV). Significant differences were found for basic measurements, BMI, BMI z-score, Cormic Index, muscle mass, medicine ball throw and SJ jump (p p p < 0.000–0.033), so these covariates should be considered in evaluations to predict the future performance of players. Finally, significant differences were found between the biological maturation groups in the distribution of the BMI classification, with the normal-weight grade being the predominant one.
