The aim of our research was to study parameters of heart rate, stroke volume of the blood of the young people, systematically engaged in parachute sport. The experiments were carried out at the airport «Куркачи», which is located in the Republic of Tatarstan. Research has covered by athletes in the range from beginning to engage in this kind of sport and to masters of sports of the international class.
Registration of the heart rate (HR) and stroke volume of blood (UOK) produced in the day of jumps, i.e. in the morning, immediately after the upgrade. Further to jump, i.e. immediately before boarding an aircraft and immediately after the landing of parachutist. To determine heart rate and WALK method is used тетраполярной chest реографии.
Studying the reaction of the heart pumping function of parachute jumpers at different stages of preparation for a jump made it possible to come to conclusion that difference in heart rate before the boarding and after the landing significantly abates depending on the sportsman qualification. Thus, the least difference in heart rate indices before the boarding and after the landing is registered among the masters of sports of the international class. At the same time, this difference remained at a high level and amounted to approximately 69-70 heartbeats per minute (Р<0.05) for sportsmen of general-class and masters of sports. The highest difference between the values of heart rate before boarding and after landing was the one of the ex-masters of sports. As the parachutists’ mastership in training grows, the reaction of the blood stroke volume, on the contrary, increases. However, both parachute sport beginners and ex-masters were observed having a negative reaction of stroke volume after a jump.
