COORDINATION OF MOVEMENTS AND PHYSIOLOGICAL INDICATORS IN YOUNG PEOPLE DEPENDING ON THE DOMINANCE OF THE HEMISPHERES OF THE BRAIN WHEN USING A JUMP ROPE

Abstract

The jump rope is a children’s cardio simulator that simultaneously trains the cerebellum, interhemispheric interaction, concentration and attentiveness. Ten minutes of jumping rope is equal to 30 minutes of running to increase the efficiency of the cardiovascular system. The purpose of this work is to evaluate the physiological parameters and coordination of movements in young people depending on the dominance of the hemispheres of the brain when using a jump rope when performing jumping exercises. Materials and methods. The object of the study is medical university students aged 18–22 years. Among them, 21.7 % of boys and 78.3 % of girls. The analysis of the results of changes in blood pressure in the subjects, depending on the revolutions made on the left and right legs and the mistakes made during the exercise, was carried out. According to the number of errors, the coordination of movements of the subject was judged depending on the dominant hemisphere. Results. Violations of coordination of movements depending on gender and the dominance of the hemispheres were noted. The boys’ right hemisphere was significantly daminated. The number of mistakes they made when jumping on the left leg was 11.1 %, and on the right — 16.67 %. In girls with a dominant right hemisphere, only 1.5 %, with the left — 1.6 % of the mistakes made during jumping exercises with a jump rope. In 22 % of girls with a dominant left hemisphere, blood pressure after exercise was registered above normal and amounted to 150/70 mm Hg, and in girls with a dominant right hemisphere, no excess blood pressure was noted.

Conclusions 1. It was revealed that the increase in blood pressure in young people when using a jump rope depends on the dominant hemisphere and on the gender of the user. 2. When using a jump rope, young people noted violations of coordination of movements depending on gender and the dominance of the hemispheres. 3. The jump rope can serve as a tool for physical training to train the motor activity of students with a low level of motor activity.
