Features of 14-15 years’ age boys’ training to physical exercises

Purpose: to optimize modes of 14-15 years’ age boys’ training to physical exercises in educational process. Material: in experiment 14 years’ age boys (n=24) and 15 years’ old boys (n=24) participated. Plan of factorial experiment was used. Results: we detected influence of quantity of exercises’ repetitions (Х1) and rest intervals (Х2) on effectiveness of physical exercises’ training. Simultaneous varying of factors as per special program ensured studying of every of them in different conditions. It permitted to receive more reliable conclusions, suitable for changeable conditions. Results of dispersion analysis witness that for 14-15 years’ age boys optimal modes of training are within 6-12 repetitions in one lesson with rest intervals 60-120 sec. In case of 14 years’ age boys it is necessary to pay attention to quantity of exercises’ repetitions in one lesson. Concerning 15 years age boys - attention should be paid to increase of rest intervals and consideration of interaction of these two factors. Conclusions: We have determined that increase of effectiveness of training process is possible on the base of analysis of regression models, calculation of optimal modes of physical exercises’ fulfillment in process of their training.
