MONITORING THE LOAD OF RESCUERS IN THE SUMMER ACTIVE PERIOD THROUGH CONTINUOUS RECORDING OF PHYSIOLOGICAL PARAMETERS WITH MEASURING BRACELETS
ABSTRACT: In order to reduce the medical damage in case of accident in the aquatic environment, it is important to have a good assessment of the changes occurring in the human body and especially those in the body of the person providing assistance in case of a water of sea accident. During the period from 21.07.20 to 22.02.21 in Varna, Bulgaria in a training water pool were measured heart rate of those preparing for lifeguards. Modern waterproof measuring bracelets were used. During the training, several different types of loads are included, which are as close as possible to the challenges of a real rescue operation, without putting the lives of the subjects at risk. By analysing the received information, it is established that the best prepared subject was a 34-year-old man with the smallest deviation from the normal values of the heart rate. The other four participants were 17-years-old students and they all had similar performance. The most significant differences between the first volunteer and the other four lie in the prior marine training, greater life experience and higher confidence of the first candidate. Another indicative finding is the establishment of better and better results in the subjects with the progress of training. An expression of this is the comparison between results from the first training of the water rescue course on one hand, and on the other hand results from the exam held on 04.03.21.
