What is the best throwing angle in throwing? Do you need to grit your teeth when running 100 meter

1. What is the best throwing angle in throwing?

According to the parabolic principle, 45° is the optimal throwing angle for an object under the condition that the throwing speed is constant. However, this principle only applies under vacuum, and the throwing point and the landing point are on the same horizontal plane. The movement of throwing events is different, one is affected by air resistance, buoyancy, wind direction, the shape and weight of the instrument itself, and the other is that the shooting point of the instrument is generally about 2 meters above the ground (i.e., the landing point).

Due to the "drop" between the shot point (throwing point) and the landing point, a ground bevel angle (that is, the angle formed by the connection between the shooting point and the landing point and the ground), the higher the shot point, the greater the ground bevel angle. In this way, if the shooting angle is less than 45°, the horizontal component of the forward force increases, which is beneficial to increase the flight distance of the instrument. It's like throwing a rock down on the top of a mountain, the smaller and flatter the angle, the farther you can throw; The larger the angle, the closer the upward shot.

Therefore, the reasonable shooting angle of each throwing event is less than 45°, and the optimal shooting angle is: shot put event 38°-42°, discus event 30°-35°, javelin event 28°-33°, chain throw and grenade 42°-44°. The best throwing angle of the above items is different, because these devices themselves have different structures, shapes, and characteristics, which form different relationships with some external factors, and in addition, the throwing methods are also different.

2. Do you need to "grit your teeth" when running 100 meters?

For the world's best athletes, the 100-meter race is often a matter of a second. So, how to win this precious moment?

The sports research team of Carl Lewis's university in the United States put forward a very strict request to him: it is not allowed to "grit your teeth" during the final sprint, and the scientific researchers of the group found that "clenching your teeth" consumes physical strength and does "useless work", which affects the performance of athletes. Lewis was initially skeptical of this advice, but training practice confirmed that "relaxed expressions" can improve the 100m by a few hundredths of a second compared to "grit your teeth".

From this point of view, Lewis's success in recent years is not unrelated to not being allowed to "grit his teeth".

The best angle of the throw in throwing is 45 degrees; When running 100 meters, we need to clench our teeth, because if we don't clench our teeth at this time, it will affect our physical dynamics and cause deflatment.

Athletes who throw hammer throws more than 80 meters have an initial velocity of 27 30 meters and a suitable angle of 40-44; No, you don't.

When investing in athletics, the angle of the throwing hand needs to be determined according to the proportion of the player's body, and the 100-meter run can only achieve better results by gritting your teeth.
