Abstract

Abstract
 
Introduction: The cardiovascular system is one of the most important parts of exercise design, and the range of effect of exercise can range from the aerobic threshold to the anaerobic threshold.Therefore, this study aimed to determine the effectiveness of exercise based on the heart rate function curve in active young men.
 
Subjects & Methods:For this purpose, 20 young and active boys with an average age of 20 to 25 years were selected as subjects and performed the helpless test of running on a treadmill. Heart rate and blood lactic acid level equivalent to aerobic and anaerobic thresholds were determined using the Dmax method and lactate measuring device, respectively. Simultaneously with the use of a respiratory gas analysis system, changes in the volume of oxygen consumption and carbon dioxide production were measured. In this study, to analyze the data, descriptive statistical methods such as categorizing information and converting them into frequency tables, adjusting the frequency and average percentage and standard deviation of variables were used. Integration operations were also used to calculate the area under the curve.
 
Results: The results showed that to determine the aerobic and anaerobic threshold, the method based on the maximum distance from the heart rate function curve as well as the level of oxygen consumption and blood lactate can be used. The heart rate function curve is also effective in determining the effective range of exercise, the area under the curve, and the step speed equivalent to the aerobic and anaerobic thresholds.
 
Conclusion: Therefore, it can be concluded that using the heart rate function curve model, the range of effectiveness of exercise can be determined and used as a new method in presenting exercise programs.
