The aim of this study was to analyze the influence of individualized training (IT) as a function of motor type and effort status on changes of in specific physiological parameters among young soccer competitors. Blood pH and lactate concentrations, and lactate dehydrogenase (LDH), and creatine kinase (CK) activities were measured at the beginning of a preparation period, a match season, and a recuperation period of a 6-month macrocycle. The differences among specific physiological parameters as a function of the preparation phase for a defined motor type were analyzed by means of a 1-way generalized linear model (GLM) for repeated measurements. The differences in physiological parameters among defined motor types for a defined preparation phase were analyzed by means of the GLM for independent data. The differences in specific parameters before and after short time effort were analyzed by means of a t-test for matched pairs. Applied experimental and analytical approaches have revealed that IT administered to specific motor types differentiates players with respect to the pH, lactate concentration, and LDH activity. Obtained results indicate also that the dynamics of these parameters reflects the player's fitness level. Analysis of CK activity as a function of a preparation phase may serve as a prognostic tool for both overtraining and physical exhaustion.
本研究旨在分析个体化训练（IT）作为运动类型和努力状态的函数对年轻足球运动员特定生理参数变化的影响。在准备期、比赛赛季和 6 个月大周期的恢复期开始时，测量血液 pH 值和乳酸浓度以及乳酸脱氢酶（LDH）和肌酸激酶（CK）活性。通过重复测量的单向广义线性模型（GLM）分析特定生理参数随特定运动类型的准备阶段的差异。通过独立数据的 GLM 分析特定运动类型之间的生理参数差异。通过配对 t 检验分析短时间努力前后的特定参数差异。应用的实验和分析方法表明，针对特定运动类型的 IT 可以区分球员的 pH 值、乳酸浓度和 LDH 活性。结果还表明，这些参数的动态反映了运动员的健康水平。分析 CK 活性作为准备阶段的函数可以作为过度训练和身体疲劳的预测工具。
