Надана характеристика стану серцево-судинної системи та її регуляторних механізмів у стані спокою, при виконанні
ортостатичної проби та в період відновлення після фізичних навантажень у дітей молодшого шкільного віку з різним рівнем
фізичного здоров’я.
Дана характеристика
состояния сердечно-сосудистой системы и её регуляторных механизмов в состоянии покоя, при выполнении
ортостатической пробы и в период восстановления после физических нагрузок у детей младшего школьного возраста с
разным уровнем физического здоровья.
The article presents the features of the reaction of
the cardiovascular system of children of primary school age in the physical exercise. The authors describe the state of the cardiovascular
system and its regulatory mechanisms in primary school children with different levels of physical fitness. Performance was measured in
children before the exercise, after exercise and during orthostatic test. Methods of research: method of assessing physical health, a method
of mathematical analysis of heart rate. 57% of primary school children have low and below the average level of physical health, and 43% -
average and above average. Children with high levels of physical health were found. Analysis of heart rate during exercise found the
reaction of the body especially schoolchildren depending on the level of physical health. Schoolchildren with average and above average
levels of physical health revealed lower values of heart rate during exercise and post them for testing on a treadmill (p <0,05). In
schoolchildren from low and lower middle level of physical health in the regulation of heart rate prevailing influence of the sympathetic
nervous system during exercise and post them for testing on a treadmill. This is evidenced by higher rates АМо (p < 0,05). In children with
average and above average levels of physical health found lower values of heart rate, AМo, myocardial tension index, index of autonomic
balance, vegetative index rate. This shows the efficiency of work compared to children from low and lower middle level of physical health.
