Research objective. To experimentally ground the technological approaches to evaluating training effects of primary schoolers’ power loads.Materials and methods. To achieve the objectives outlined, the research used the following methods: analysis of scientific and methodological literature, pedagogical testing, modeling, pedagogical observation and experiment, methods of mathematical experiment planning (complete factorial experiment, 2k type), discriminant analysis. The participants in the study were 32 second grade boys.Research results. The training pattern affects the dynamics in the test results for the second grade boys. The test results can improve provided that the power load brings about significant changes after the training at each spot, after the training (immediate training effect), and twenty four hours after the power load (delayed training effect). The higher the dynamics is for the immediate and delayed training effects, the more significant are the improved power tests results observed after as few as three lessons.Conclusions. The discriminant function can be used to classify the training effects of the second grade boys’ power loads. The first canonical function explains the results variation by 85.0%, the second one — by 14.0%. This suggests that they are highly informative. The centroid coordinates for five groups allow to interpret the canonical functions according to the role differentiating the grades by the training effects of the primary schoolers’ power loads. The positive pole of the first function has the condition centroids at the beginning of the power loads, after three, six, nine and twelve lessons; the negative pole has the centroids of the training effects after the power loads, after the lesson, after 24 hours.Thus, the reaction to the power load has immediate, delayed and cumulative training effects.
