Abstract
The purpose of this study was to analyze differences between endocrine markers
in soccer players, based on playing positions, and correlations between endocrine
markers (testosterone, cortisol, growth hormone, and insulin-like growth factor-1), with
accumulatedworkload training and fitness parameters [maximal oxygen uptake (VO2max),
countermovement jump (CMJ), and isometric maximal strength (1-RM) of the knee for
hamstring (ISH) and quadriceps (ISQ) muscles] during early-, mid-, and end-seasons.
Twenty-four elite soccer players under 17 participated in this study. The results showed
that there was no difference between levels of the endocrine markers among the different
positions of the players. Significant correlations were observed between endocrines
parameters and fitness performance (ISQ, ISH, VO2max, and CMJ). Regression analysis
showed that 1-RM and VO2max were the best predictors of endocrine markers. These
findings demonstrated that the activity profiles of youth soccer players were not
influenced by endocrine markers. Also, it may be assumed that endocrines levels can
be used to better explain the physical capacities of this population. Finally, endocrines
markers may help to predict changes in 1-RM and VO2max.
