Comparative assessment of strength indexes indicators of the leading hand and back among children of Uzbekistan engaged in different sports groups

Studying of muscular activity features, including degree of development of muscle strength of a leading hand and back, taking into account an orientation of training process defines regularities and features of diagnostics promoting control of adaptation of the leading systems of young athletes’ organism. Objective: to give a comparative assessment of strength indexes among pupils’ athletes of Uzbekistan depending on sports group and an experience of sports activities. Materials and methods: about 14000 pupils’ athletes at 11-17 years old living in Tashkent, Nukus, Samarkand, Gulistan, Qarshi and Urgench were examined. Based on anthropometrical parameters of physical development strength indexes were calculated. Results: the indices of boys athletes of Uzbekistan were following: small force of an arm was considered at strength index <30% of body weight, force is lower than average - from 30 to 41%, average force - from 42 to 64%, force is higher than average - from 65 to 74%, larger force - >74% of the weight. In girls: respectively <35% - small, from 35 to 39% - below average, from 40 to 51% - average, from 52 to 57% - above an average and >57% - larger force. Levels of an index of back strength in children athletes from 7 to 17 years were following: in boys - the weak back force was considered at back strength index <101% of the weight, force is lower than average - from 101 to 119%, average force - from 120 to 156%, force is higher than average - from 157 to 174%, larger force >174% of the weight; girls have small force of a back - <83% of the weight, force is lower than average - from 83 to 92%, average force - from 93 to 109%, force is higher than average - from 110 to 117%, larger force - >117% of the weight. Conclusions: reliable positive changes of a strength index of a hand have been revealed among the boys engaged in combat sport, team, complicated coordinating and cyclic sports for more than 1 year, and among the girls engaged in combat sport, acyclic and complicated coordinating sports. Back strength index is significantly higher among the boys engaged in combat sport, acyclic and complicated coordinating and administrative sports for more than 1 year, and among girls engaged in combat sport, acyclic and team sports. A high level of strength training of pupils is observed in these sports groups.
