ANALYSIS OF MORPHOMETRIC INDICATORS OF RIGHT-HANDERS AND LEFT-HANDERS IN THE SECOND PERIOD OF CHILDHOOD

Аннотация

The analysis was carried out on 10-year-old children of secondary schools №32. The results of the study showed that 10-year-old left- handed children lagged somewhat behind in physical development (body weight and chest circumference) compared to right-handed children of the same age, while the height and size of the left hand increased significantly. Keywords. anthropometric indicators, height, body weight, interhemispheric asymmetry I. Introduction. Today children's applause is relevant and does not have the problem of a certain approach in the field of pedagogy and physical education. Some researchers have developed methods for teaching squirrels to the right, while others, on the contrary, have a positive attitude to the phenomenon. An individual approach has not been developed. In our opinion, this problem requires one solution, since different forms of training and retraining of the left hand can negatively affect their physical and mental development. The issue of a differentiated approach to teaching (the teacher takes into account the individual characteristics of a student or a group of students in the learning process) is the basis of modern pedagogy [1]. The negative attitude towards the left hand has a long history and is reflected in the events, actions and attitudes associated with the right and left hand in different cultures [2]. As a rule, in different cultures, positive qualities are associated with the right side, negative - with the left. Perhaps this is one of the manifestations of the right-left attitude, as in different cultures. Many researchers note that among left-handed children there are children who are able to perform motor movements at a high level, but there are also certain difficulties in performing awkward and incoherent movements and developing skills [7,11]. This is probably due to the congenital left hand. The advantage of the left hemisphere lies not only in the superiority of the left hand in performing motor movements, but also in the distribution of various functions (motor, visual, sensory, etc.) between the right and left hemispheres as a kind of reflection of interhemispherik asymmetry [1,10]. 106 CURRENT APPROACHES AND NEW RESEARCH IN MODERN SCIENCES International scientific-online conference We are often confronted with similar views of the left hand and relationships like this. Perhaps the decisive factor is negligence, misunderstanding of the biological mechanisms of flattery, and most importantly, the inability of children to accept a variety of individual differences, their abilities, inclinations, differences in reactions, under the influence of the same factors, these individual characteristics [2]. The number of left-handers in the world has a positive trend: if in 1928 3.3% of left-handers and 4.7% of left-handed men were identified, then in 1973 - 8.8% of left-handers and 10.4% of left-handers. Left-handed men, 1978-1988 Over the years, the number of left-handers increased by 12.4%, and left-handed men - by 13.9%. The increase in the number of students in schools in Ishim in 1998 was 5.2%, in 1999 - 6.1%. , in 2000 - 5.5%, in 2001 - 7.5%, in 2002 - 7.9%, in 2003 - 8.3%, in 2004 - 8, 6% [12]. A decrease in intellectual abilities of a protein may have only one cause - it is a developmental pathology, but healthy proteins can also have remarkable abilities, there are plenty of such data [2]. Lefties have peculiarities of visual perception of information. It was found that the well-being of the visual system is especially characteristic of left-handed children [11,18]. On the contrary, cases such as asthenic neurosis are more common in children of primary school age. This is accompanied by a decrease in working capacity and activity, increased fatigue, and rapid fatigue. The peak of activity is observed only in the first two lessons, after which a decrease in endurance and motor movements is observed in children. In the following hours, children feel tired, lethargic and lose interest in new information [1,5]. It is recommended to start teaching children at school, as well as problems with such disorders as coordination of movements, including the lack of fine motor skills of the leading hand and the perception of body shapes through the program, the whole system discusses exercises for corrective work has significant opportunities in practice [6,11, 16]. The analysis of the available literature showed that the anthropometric parameters in one or another part of the body were not studied individually and to a certain extent in the “lefthanded” complex for children. There is no data on the morphometric parameters of the body parts of left-handed children depending on age and sexual demorphism. All this requires a deep study of the problem and analysis of the data obtained in the future. 107 CURRENT APPROACHES AND NEW RESEARCH IN MODERN SCIENCES International scientific-online conference Objective of the study: to study the comparative characteristics of mo
