Abstract
According to the vast majority of experts, aerobic exercises are basic in fitness. Their effectiveness in the practice involves the rational regulation of load parameters, one of which is the intensity of exercises. However as practice shows the proposed methods for determining the necessary intensity of aerobic exercises do not quite adequately take into account the individual characteristics - age and fitness level.
 The purpose of the research is to evaluate methods for calculating intensity of aerobic exercise in fitness. In our studies we proceeded from the fact that calculation methods should consider two main trends.
 
 At the aging heart rate at rest slightly rises, and the upper pulse during exercises decreases.
 A higher fitness connected with significant decrease in heart rate at rest and an increase in its upper rate at critical intensity (expanding the range of heart rate during exercise). According to the vast majority of specialists, aerobic exercise is basic in wellness physical culture. Their effective application in the practice of wellness work implies rational regulation of the load parameters, one of which is the intensity of work.
 
 As a result the analysis of real situations it was demonstrated that the calculation intensity of aerobic activity according to heart rate indicators using formulas that take into account only the age of the practitioners is applicable in a certain age range (up to about 50-55 years). As age increases the correctness of such calculations decreases and loses its meaning in certain point due to the fact that calculated indicators of heart rate during exercises may be less than those at rest.
 Karvonen formula which takes into account the individual level of physical fitness for heart rate at rest is more accurate for determining heart rate in aerobic exercise. Its using allows us more correctly determine the lower pulse during exercises declining it because decrease in resting heart rate. However this formula also declining the upper pulse during exercises, although it should increase as the cardiovascular system improves.
Highlights
Более точной для определения ЧСС в аэробных упражнениях является формула Карвонена, которая учитывает индивидуальный уровень физической подготовленности по ЧСС в покое
Перспектива дальнейших исследований будет связана с разработкой способов расчета рабочей ЧСС для оздоровительной физической культуры, более адекватно учитывающей возраст и уровень подготовленности занимающихся, чем ныне существующие формулы
Summary
РАСЧЕТ ИНТЕНСИВНОСТИ АЭРОБНЫХ НАГРУЗОК В ОЗДОРОВИТЕЛЬНОЙ ФИЗИЧЕСКОЙ КУЛЬТУРЕ В статье рассмотрены формулы расчета интенсивности аэробных нагрузок в оздоровительной физической культуре. В результате анализа реальных ситуация было продемонстрировано, что расчёт интенсивности аэробных нагрузок по показателям ЧСС с использованием формул, учитывающих только возраст занимающихся, применим в определенном возрастном диапазоне (приблизительно до 50-55 лет).
