Abstract:
Information concerning the kinematic parameters of the diving-entry phase is very
limited in current information sources. There are publications of the group of authors, including
the authors of the present article [1;2; 3; 4], concerning the problem of splashes formation in
competitive dives. They don’t reflect all theoretical and practical questions of this kind of sport.
Kinematic parameters of the dives fulfillment from 10-metres platform were not previously
studied and may differ significantly from 3-metres springboard dives. In this connection the
presented article is dedicated to kinematic parameters of springboard diving analysis among
the participants of the Olympic Games 2020. Research methods: video materials analysis,
measuring the angles of the athletes’ body positions by means of a special computer program
“Screen protractor”, methods of statistical data processing (calculation of X mean values and rootmean-
square deviations). Material. The article describes kinematical analysis of the dive final
phase fulfillment by the World’s strongest athletes on the basis of video material of the Olympic
Games 2020 final competition in Tokyo. Results and novelty of the research work. We
defined kinematic parameters of the I and IV class dives’ final phase fulfillment by high-class
athletes. It was revealed that rotation stop in the I and IV class dives is fulfilled by the athletes in
two ways: opening through the angle with considerable flexion in pelvis and straightening at a big
angle relative to water and smaller angle in hip joints. It was revealed that the angle in shoulder
joints significantly influences the quality of water entry. “Amortized” water entry in springboard
dives is the key evaluation criterion for the success of a dive. Conclusion. During the I class
dives fulfillment athletes have less time (twice less) for entry hands position, than during the IV
class dives fulfillment. That is why an athlete has to fulfill the final movements with higher speed
and it decreases the possibility of splashes formation and as a result, influences the quality of
water entry estimation.
