الخصائص البيوميكانيكية لمهارة ثلاث دورات و نصف هوائية خلفية مكورة معكوسة من المنصة المتحركة 3 م للاعبي النخبة في رياضة الغطس

Abstract EN

Performance of high-level players to find the most important biomechanical properties that contribute decisively to the skill performance and that can be used in the future to modify and develop the technical performance of scuba diving players.

In terms of biomechanical characteristics of the performance of three round and half antenna spinning back mirrors from the moving platform 3 meters for high level players in scuba diving.

• The two researchers used the descriptive method using the biomechanical kinetic analysis of the skill in question, due to its relevance to the nature and objectives of the research.

The kinetic analysis sample was also chosen intentionally, and consisted of (1) an international diving player for the Egyptian team, who won first place in the FINA Diving Grand Prix 2019 held in Heliopolis Club in the city of Sunrise during the period from 21 to 24/6 / 2019, with a total number of points (425,90) points.

The recommendations that can be extracted from the results of kinetic analysis to upgrade the skill performance level of the performance of three and a half pairs of background spherical reverse mirrors from the mobile platform of the sample in question.

In order to provide the best assistance to scuba diving players when performing the skill under discussion with respect to bearing ball position during aerobic cycles that require greater muscle effort to resist the increased centrifugal forces resulting from increased rotational speed, the focus should be on training the fixed muscle contraction in the directions of the flexion of the thighs, and bending Knees, holding the torso forward and extending backward, raising the arms above the head, and the elbows bent to hold the legs.

The player must also be trained on greater control of the decentralized contractions of the muscles during the slowdown of the high rotational speed, which allows safe and vertical entry into the water.
