The article analyzes the methods of calculating the intensity of aerobic health-improving loads and presents own solution the problem.
The effective use of aerobic exercises is based on the formula calculation of the parameters of physical activity corresponding to the individual characteristics of the practitioners, among which one of the most important is intensity. However, the practical application of the proposed formulas indicates that they do not always adequately take into account the most important, in this case, age characteristics and the functional state of the cardiovascular system.
The purpose of the research is to develop a method for determining the intensity of aerobic health-improving loads which makes it possible to calculate the target heart rate more adequately than the currently existing options.
Among the existing formulas the most adequate for calculating heart rate in the process of health-improving aerobic exercise is Karvonen's formula which takes into account not only age but also heart rate at rest which reflect the functional state of the cardiovascular system. Its advantage lies in the more correct determination of the lower target pulse. The disadvantage of this formula is that it reduces, rather than increases, the upper target pulse due to the increased efficiency of the cardiovascular system.
During the theoretical research it was established that it was impossible to develop a single formula that would allow to correctly determine the upper and lower target pulse. In this regard we came to the conclusion that to calculate the lower heart rate it is necessary to use the Karvonen formula and the upper tagert puls should be determined by the formula developed by us. It is based on the Haskell & Fox formula (HRmax = 220 - age). The proposed additions determine the upper heart rate as the result of subtracting the individual heart rate from the average age heart rate. A procedure for calculating specific puls based on knowledge of the upper and lower heart rate is proposed.
