Cardiograph in a T-shirt
Russian scientists have built ECG sensors into athletes' T-shirts
Researchers from South Ural State University have created unique T-shirts that continuously monitor the heart rate and the state of the human heart. They will help athletes better prepare for competitions and will save the lives of many cores, the press service of the "Project 5-100" reports.
Figure from the article Kodkin, Khafizova The method of analysis of functional capabilities of athletes by continuity of the recorded ECG upon variation of physical exertion – VM.
"We register an electrocardiogram in conditions that have not been done before. When people exercise, the ECG signals are greatly distorted. In our recorders, the losses are significantly less than in standard monitors, and the signals are restored very quickly. They will allow us to form more advanced training methods," said Vladimir Kodkin from SUSU in Chelyabinsk.
Heart and vascular diseases, as well as strokes and various forms of senile dementia are today one of the main causes of death of people in the first World countries, and one of the main items in the expenditures of the health services of these states.
According to current WHO estimates, several hundred million inhabitants of the Earth will suffer from such problems by 2030, which is why today scientists are actively studying how these diseases develop and trying to find a way to reduce the likelihood of their acquisition in older years of life.
On the other hand, increased competition in sports forces many coaches, sports doctors and athletes themselves to use the latest medical discoveries and technologies during training and even during the competitions themselves.
In addition, continuous monitoring of the health of athletes will help to avoid tragic situations that often occur on ice fields or football fields due to the presence of congenital heart diseases in players.
The problem, as Kodkin notes, is that intense physical activity is almost completely incompatible with existing ECG recorders, which are usually used to check the condition of the heart and blood vessels in hospitals.
"When people do sports, the ECG signals are greatly distorted. In our recorders, the "losses" are significantly less than in standard monitors, and the signals are restored very quickly. This complex experiment allowed us to understand what needs to be done to improve the quality of recorded ECG signals," the scientist notes.
Researchers from Chelyabinsk solved this problem by creating compact, wireless and at the same time very accurate ECG sensors that can be embedded in T-shirts and other types of athletes' clothing and continuously read data from them from anywhere in the world.
The scientists tested the work of these sensors on three athletes – a weightlifter, a track and field athlete and a fitness instructor, who performed various exercises for an hour and were constantly on the move.
As these experiments showed, the sensors coped with this task by transmitting a very clear signal to a neighboring computer, by which it was possible to determine the level of load, its type, individual differences between representatives of different sports disciplines and other important parameters that may be of interest to both coaches and sports doctors.
Such "smart" clothes, according to scientists, will be useful not only for athletes, but also for people suffering from heart problems. She will help their relatives to constantly monitor their condition and instantly help them if their heart has stopped or serious problems have appeared in its work.
