Effect of heart rate monitoring on increasing motor density of physical education lessons in children with autism spectrum disorder

We apply continuous monitoring of heart rate at physical training lessons in children with autism spectrum disorder and assess its impact on increasing motor density of physical training lessons. The study engaged children with motor dynamic stereotype. The choice of this group is due to the need to properly dose the physical load: the number of repetitions, intensity and sequence of exercises to increase the motor density of physical training lessons and increase the time of work in the moderate intensity zone. The estimation of motor density of training sessions was carried out using the method of timing and was calculated by the formula of the ratio of motor activity to the total observation time in percent. The control technique we used, allowed us to increase the motor density of physical training lessons from 62.5 to 72.5 %. In the main part of the lesson time in the moderate power zone at the initial stage was 3 minutes. At the end of the study in the experimental group, this value increased by 33.3 %. Electronic monitoring of heart rate at the lessons in students with autism spectrum disorder allows for effective control of physical activity, which increases the motor density of classes without worsening the psycho-emotional state of the child.
