OBJECTIVES:: The aims of the present study were to evaluate links between biochemical markers and competition and training conditions, overtraining questionnaire scores, and anthropometric characteristics of young elite rugby players, and to identify evolving profiles of fatigue during the sports season. METHODS:: Twelve elite rugby players were included in the study. The tests were carried out every 15 days over the course of one sporting season from July until March, including the inter-season. Changes in body composition parameters, blood biochemistry, and scores on various questionnaires were examined. RESULTS:: The majority of the biochemical parameters and subjective variables showed significant variations over time. There were significant positive correlations between overtraining scores and alanine amino transferase (r = 0.24, p < 0.05) and creatine phosphokinase (r = 0.3 p < 0.01) levels. In addition, game time was significantly correlated with changes in creatine phosphokinase (r = 0.46, p < 0.01), while difficult training sessions were significantly correlated with changes in both creatine phosphokinase (r = 0.27, p < 0.05) and alanine amino transferase (r = 0.33 p < 0.01). CONCLUSION:: We suggest that regular monitoring of these biochemical parameters may provide important information for the coach on the fatigue of rugby players and their perceived difficulty of training. |
