Simulation of process of 14-15 years old girls’ training of light athletic and gymnastic exercises

Purpose: to optimize physical exercises’ training regiment in educational process of 14-15 years old girls. Material: in experimentgirls of 14 years age (n=24) and 15 years (n=24) participated. The plan of factorial experiment was used. Results: we have shown influence of quantity of exercises’ repetitions (Х 1) and rest intervals (Х 2) on effectiveness of physical exercises’ training. We have offered complex approach to studying of objects, which admits simultaneous varying of several factors for assessment of their interactions’ influence. Simultaneous varying of factors by special program ensured studying of each of them in different conditions. It permitted to receive more reliable conclusions, suitable for changeable conditions. Conclusions: it was established that increase of training process’s effectiveness is possible on the base of analysis of regressive models, calculation of optimal modes of physical exercises’ fulfillment in process of their mastering at school physical culture lessons
