PHYSICAL DEVELOPMENT, THE LEVEL OF PHYSICAL AND TECHNICAL PREPAREDNESS OF 14 - 15 YEAR OLD YOUNG WEIGHTLIFTERS OF DIFFERENT WEIGHT CATEGORIES GROUPS

Annotation. Purpose: explore physical development, the level of physical and technical preparedness of young weightlifters of different weight categories groups. Material: the study involved 36 athletes. Athletes age 14-15 years. Results: present physical development, the level of physical and technical preparedness of athletes who are preparing for the championship of Ukraine. Found that indicators body length athletes tend to increase with increasing weight category groups by 15,0% (p <0,05). It is estimated that the active body mass index increases with sportsmen groups weight categories by 20,0% (p <0,05). It is proved that the difference between the strength of the left and right brushes all weight categories of groups 2.4%. The analysis of the indicators in the control of technical readiness exercises in the snatch. Conclusions: to determine the trends of physical development, the level of physical and technical preparedness of athletes of different groups of weight categories. Indicator is dynamometry athletes increased with increasing weight category groups by 47,7% (p <0,05).

Introduction 1  Intensive trainings with weight bar facilitate manifestation of maximal strength of junior weight lifters owing to strengthening of health and development of active muscular mass.
Analysis of recent researches and publications witnesses that most of authors in weight lifting wanted [1][2][3][4] to generalize results of study of physical condition indicators, levels of physical and technical fitness of the strongest junior weightlifters.With it in the couse of study of physical condition and physical and technical fitness of junior weightlifters of different weight categories we have not found reasons of selection for competitions neither in theory and practice of weight lifting nor in domestic and foreign literature.That is why, on the base of analysis of coaches' and sportsmen's questioning we think that this problem shall be studied.
The work has been fulfilled in compliance with "Combined plan of SRW in field of physical culture and sports for 2011-2015" of Ministry of youth and sports of Ukraine by topic 2.8."Improvement of sportsmen's training in separate kinds of sports" (state registration number 0107U001647).

Purpose, tasks of the work, material and methods
The purpose of the work is analysis of indicators of physical condition, level of physical and technical fitness.
The methods of the research: 1. Analysis of scientific-research literature.2. Questioning of coaches and sportsmen.3. Anthropometry.Caliperometry. 4. Determination of technical fitness with the help of video computer analysis of space characteristics of jerk weight lifting in control exercises.5. Pedagogic observation over training process.6. Methods of mathematical statistics.

Results of the research
We studied physical condition's indicators, levels of physical and technical fitness of junior weight lifters.Indicators of mass body content of junior weight lifters are informative indicator of their functional potentials and level of fitness [1,3,4].Thickness of junior weightlifters' fat layer depends on hereditary factors, which can not be changed, but quantity of fat can be changed by regulating of physical loads volume and mode of eating.Index of active body mass (IABM) permits not only to compare fitness of different sportsmen but also permits to control of body mass increasing.Trainings of junior weightlifters and their eating permit increasing of muscular tissue [1][2][3][4].
In our opinion distribution of fat layer on body segments of junior weight lifters depend on body mass and qualification of sportsmen and is individual by character [1,3,4].
Analysis shows that difference between strength of left and right hands of all weight categories is 2.4 %, that is proved by researches of advanced specialists [1,3,4].
We gave indicators of technical fitness of 14-15 years old weight lifters in jerk in table 3. Analysis shows that time of fulfillment of pulling increases with increasing of weight category -by 0.7 % (р < 0.05) and 5.0 % (р < 0.05); height of rising, depending on body length -by 1.1 % (р < 0.05) and 0.1 % (p > 0.05); height of fixing in phase of final acceleration, depending on length of body -by 1.3 % (р < 0.05) and 0.1 % (p > 0.05), that is proved by researches of advanced specialists [1,3,4].Conclusions 1.We have fulfilled analysis of indicators of physical condition, physical and technical fitness of junior weightlifters of different weight categories, who train for Ukraine junior championship.2. We determined that indicators of body length have trend to increasing with increasing of weight category -by 9.5 % (p < 0.05) and 4.9 % (p < 0.05).We proved that index of active body mass increases with increasing of weight categoryby 1.6 % (p > 0.05), and 18.0 % (p < 0.05); difference between strength of left and right hands of all weight categories was -2.4 %; indicators of backbone dynamometry increase with increasing of weight category -by 36.3 % (р < 0.05) and 8.3 % (р < 0.05).
3. We have determined dependence of technical fitness in jerk indicators of junior weightlifters for different weight categories.
Further researches imply to fulfill in direction of studying of other training problems of different age and weight groups of weightlifters.
