EFFECTIENESS OF JUNIOR FORM PUPILS’ TRAINING OF GYMNASTIC EXERCISES IN DIFFERENT MODES OF THEIR FULFILLMENT

Purpose: determination of junior pupils’ motor skills’ formation. Material: in the research 172 pupils participated: in every parallel of forms – 48 pupils. Results: effectiveness of 1 form pupils’ is positively influenced (exercise – forward roll) by increase of attempts up to 12 times; quantity of repetitions in one attempt shall be within 13. For 2 form pupils (exercise – forward roll), 3 form (exercise – vault over the width of gymnastic horse) and 4 form pupils (exercise – vault over width of gout with bent legs) positive influence was rendered by increase of repetitions in one attempt up to 3 times and quantity of attempts within 6-12 times. Attention shall be accentuated on quantity of exercise’s repetitions in one attempt (2-4 forms) and quantity of attempts (4 from). Conclusions: Experiment of 2 type permitted to study multi-factorial structure of modes of 1-4 forms’ schoolchildren’s training to physical exercises; to specify optimal correlations of quantity of attempts, quantity of repetitions in one attempt and rest interval in period of acrobatic exercises’ and gymnastic vaults’ training at physical culture lessons.

In works of O.M. Khudolii, О.V. Ivashchenko [31,35] there was studied level of physical exercises' mastering and its dynamic.For determination of training process's laws study of level increment of physical exercises' mastering as a criterion of training effectiveness is rather promising.Thus, study of junior schoolchildren's motor skills' formation is rather important and urgent.

Purpose, tasks of the work, material and methods
The purpose of the work is determination of junior pupils' motor skills' formation.
The methods and organization of the work: in the work we used analysis and generalization of scientific and methodic literature data, theoretical general-scientific methods: analogy, analysis, synthesis, abstraction, induction.Besides, we used empiric general scientific methods: observation, testing, experiment.
In the process of planning of our research we used conceptual approaches to planning of experiment, which were substantiated in works of O.M. Khudolii and Т.V. Karpunets [24], O.M. Khudolii and O.V. Ivashchenko [31,35], O.M. Khudolii [26].In dissertation works of O.M. Khudolii [28], O.V. Ivashchenko [11], V.І.Міroshnichenko [16] there was stated that control over training process would be more effective with determination of training modes on the base of regressive models by results of full factorial experiment (FFE) of type FFE 2 к .
In the research we used plans of factorial experiment of type FFE 2 3 (see table 1).We researched motor modes of training: forward roll (1 st , 2 nd forms' pupils); vault over width of horse (3 rd form pupils); vault over width of gout with bent legs (4 th form pupils.The purpose of FFE was to optimize modes of training and determine peculiarities of formation of 1 st -4 th form schoolchildren's motor skills on the base of regression equations' analysis. In pedagogic experiment we studied influence of quantity of attempts (x1), quantity of repetitions in one attempt (x2) and rest intervals (x3) on change of mastering level's increment of 1 st -4 th form schoolchildren.
In the process of gymnastic exercises' training we assessed level of mastering with alternative method ("fulfilled", "not fulfilled"), considered probability of exercise's fulfillment (p = n/m, where nquantity of successfully fulfilled attempts, mgeneral quantity of attempts).Then we analyzed increment of mastering of gymnastic exercises.
In training of junior school age children we used method of algorithmic orders.Transition to next exercises was realized after three successful attempts.In 1 st -4 th forms we trained forward roll,, vault over gout with legs apart and legs bent [10, 36,].
Training of forward roll was in 1 st -2 nd forms.Technique of fulfillment: forward rollforward movement of body with full turnover and successive touching floor with shoulders and back.Forward roll is fulfilled from squat position, hands are placed at 30-40 cm from tip toes (resting on hands) unbend legs.Strongly bending back and dropping head on chest fall down ahead, bending arms.Slowing fall, softly rest on neck and blades, quickly tuck and make roll.
