Background and objectives Development of a small psychomotor is one of the main factors of success in training. However, there is a lack of awareness of the relationship of the physical fine psychomotor with physical development of children and adolescents. In this regard, there is a task of evaluating these two forms of development of pupils and their relationship in the learning process.
Methods The study included a comprehensive longitudinal study of 220 students from 1 to 11 classes in 5 Moscow schools. The indicators of physical development and psychomotor were annually estimated by methods of visual-motor coordination in conducting with rod inside the groove, tapping test, a simple sensorimotor reaction. The study identified a group of schoolchildren with excess body mass.
Results It was found that students with excess body mass demonstrated a significant negative distinction from students with normal body mass. Frequency of touchings the edges of the groove at visual-motor coordination in children with excess body weight is up to 9,6% (p<0,05); time of touching is up 16,3% (p<0,001); latent component of a simple sensorimotor reaction is up 5,1% (p<0,01).
At the same time indicators of tapping test and motor component of simple sensorimotor reaction did not show any differences.
Conclusion Students with excess body mass have less developed psychomotor, but accuracy of coordination and decision-making time suffer, which should be considered in solving problems of their health and increasing the efficiency of the educational process.
