![]() ![]() We select from several technical parameters with significant differences, choose from several technical parameters that have significant difference, and calculate the correlation parameters and results. This paper mainly studies and analyzes some important technical parameters and achievements of elite female discus athletes aged 2018∼2021 by using the methods of Pearson, partial correlation and grey correlation analysis. This paper introduces the concept of champion model and puts forward a targeted technical training system based on the differentiation research of champion model. Training starts from the construction of accurate personalized technology and physical fitness model. The brilliance of Chinese women's throwing benefits from the closed-loop personalized training system. Athletes will typically throw six times per competition.The personalized training of elite athletes is the key to the breakthrough of Chinese track and field events in the Tokyo Olympic Games. For the distance to be measured, the discus must land inside a marked sector, and the athlete must not leave the circle before the discus has landed, and only from the rear half of the circle. The thrower typically takes one-and-a-half spins before releasing the discus. The discus throw is considered the classic event of athletics the Greek sculptor Miron sculpted the bronze sculpture of the Discus Thrower around 450 BC. A slightly smaller discus weighing 1 kg and 180 mm in diameter is used in women's discus throw.The modern discus used in international men's competition is about 219 mm in diameter and 44 mm thick at its centre.Here are details for discus weight per age group for male and female. However, if the throw is correct, higher weights may result in longer distance. For any given rotation rate, the heavier discus in the rim will generate more angular momentum and therefore be more stable, although it's harder to throw. The rim must be smooth with no roughness or finger grip. When selecting a discus, consider the flight characteristics and the athlete's ability to create rotary velocity (spin). The discus can be solid or hollow, made of wood or other suitable materials, surrounded by metal rings, and the edges of the metal rings should be rounded. Let's find out more details about the standard discus size here. There are certain rules to follow, and weights and sizes will differ depending on the age group. The discus rim is made of wood or similar material, with a smooth metal rim and small, circular brass plates set flush into its sides. In terms of technical structure, the complete discus-throwing process can be divided into five parts: grip, preparatory posture, pre-swing rotation, final force, and body balance after the discus is thrown. In 1912, the International Amateur Athletic Federation unified the weight and size of the standard discus.ĭuring the game, the discus thrower holds the discus in one hand and throws it as far as possible in the throwing circle. In 1896, the Athens Olympics included the men's discus as an event. In the ancient Olympic Games, discus became an official event, but the equipment used in the competition was flat stones, and there was no uniform standard for weight and size. Discus throw originated from the ancient Greeks' entertainment of throwing stone chips. The discus throw is a popular sport with a long history. ![]()
