Evaluation of Training Effects of Primary School Girls’ Power Loads

Abstract

Research objective. To experimentally ground the technological approaches to evaluation of the training effects of primary school girls’ power loads.
 Materials and methods. To achieve the tasks outlined, the research relied on the following methods: analysis of scientific and methodological literature, pedagogical testing, modeling, pedagogical observations and experiment, methods of mathematical experiment planning (complete factorial experiment, 2k type), discriminant analysis.
 The participants in the study were 32 second-grade girls.
 Research results. The training pattern effects the dynamics in the test results for the second-grade girls. The test results can improve provided that the power load brings about significant changes after the training at each spot, after the lesson (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 results of the power tests observed after as few as three lessons.
 Conclusions. The discriminant function can be used to classify the training effects of the second-grade girls’ power loads. The first canonical function explains the results variation by 96,2%. This suggests that it is highly informative.
 The centroid coordinates for five groups allow to interpret the canonical functions according to their role in differentiating the grades by the training effects of the power loads of the primary school girls. 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. The biggest cumulative training effect is after twelve lessons (3.045).
