On the issue of standardizing the volume of weekly motor activity for schoolchildren with intellectual disabilities

The purpose of the study is to compare the weekly motor activity levels of children with intellectual disabilities with the requirements and recommendations of regulatory documents on physical education and sports. Research methods and organization. Methods used included the analysis of regulatory documents, examination of medical record extracts, a rapid assessment of health indicators according to Apanasenko, and a week-long heart rate monitoring using individual wearable devices. Heart rate indicators and the duration of time spent in pulse zones of varying intensity were recorded over a week in schoolchildren aged 12–14 with mild intellectual impairment. Research results and conclusions. The monitoring data were compared with the health status of the participants, and it was determined that, when performing almost all variants of the recommended motor activity volume, the health of the surveyed schoolchildren corresponds to the following levels: low, below average, and average. This can be attributed to the fact that the dominant pulse zones during the implemented load are those of low and moderate intensity. This fact confirms the insufficiency of solely temporal and quantitative characteristics as a basis for weekly physical activity recommendations, adherence to which can create conditions for health-promoting and developmental effects, and underlines the relevance of the approach developed by the authors for the correction of these norms.
