Summary

In this video, the topic of discus throwing in athletics is explored, including its definition, equipment, and techniques. The discus is a circular object, typically made of aluminum with a wooden or rubber center, and its weight differs for men (12 kg) and women (1 kg). The video covers the correct throwing technique, with a focus on grip and body positioning, demonstrating both side-throwing and back-throwing styles. Viewers are encouraged to learn through a written assignment and a practical task to demonstrate their understanding by mimicking the discus throw with improvised equipment. The lesson concludes with instructions to download further learning materials.

Q & A

What is discus throwing?

Discus throwing is an athletic sport where the objective is to throw a discus as far as possible, with a throwing angle of approximately 45 degrees.

What materials are used to make a discus?

A discus is typically made of a circular metal body, often with an aluminum or other material outer layer. The center can be made of wood or rubber, which serves as the weight of the discus.

For male athletes, the discus weighs 12 kg, while for female athletes, the discus weighs 1 kg.

What is the purpose of the protective boundary in discus throwing?

The protective boundary, usually made of a hard material, is designed to prevent the discus from hitting the audience and ensures safety during the throw.

How is the discus held when throwing?

The discus is held by gripping it with the fingers, where the tips of each finger, excluding the thumb, touch the discus. The distance between the fingers should be slightly wide, and the discus rests on the palm at its center of mass.

In the sideways style, the body is positioned sideways at the beginning of the throw, with the throw directed to the side.

What is the backward style of throwing the discus?

In the backward style, the athlete starts by turning their back to the throwing direction and performs a more complex motion, including a body rotation, to launch the discus.

What are the key differences between the sideways and backward throwing styles?

The sideways style involves a side-facing body position at the start of the throw, while the backward style requires the athlete to face away from the throwing direction and include a rotational movement of the body.

What practical task are students required to complete in the lesson?

Students are tasked with demonstrating both the sideways and backward discus throwing styles, using improvised objects such as metal can lids, plastic plates, or similar items as substitutes for the discus.

What kind of video task are students asked to perform?

Students must record a video demonstrating their discus throw, including both the sideways and backward styles, and submit the video as part of their practical task.
