Modification of heart rate in lactacid anaerobic effort among amateur athletes

Abstract

Lactacid anaerobic efforts are frequently encountered in the practice of physical exercises by amateur athletes, while the modification of heart rate in such activities differs from one athlete to another, mainly depending on the training level. The purpose of the paper is to monitor the heart rate in lactacid anaerobic effort and to highlight the immediate modification caused by effort. 15 male amateur athletes performed the race of 200 m, at peak intensity. The modification of heart rate during effort, in 13 of the athletes, did not reach Hrmax calculated by the formula 220 – age, but it exceeded in case of two of the research subjects.

Heart rate in maximum aerobic effort and anaerobic lactacid capacity in female handball players

“…Anaerobic effort is predominantly lactacid, which results in increased lactic acid production in the muscles. Anaerobic lactacid capacity is the potential of the athlete to sustain an exhausting effort under the conditions of using the energy substrate specific to anaerobic lactacid metabolism (Honceriu & Trofin, 2017).…”
