The key and difficult points of running and jumping.

The key and difficult points of running and jumping: the upper body is upright, the swing arm is fast, the thigh is high, and the forefoot touches the ground. Running and jumping is a basic dance step in physical education class's rhythmic dance, which many students can't learn. Through teaching practice combined with incidental rhythm (the content of music class), students can be taught to run and jump quickly. This paper introduces this.

Definition of running and jumping

Running and jumping is a kind of sport, similar to triple jump, which is farther than jumping. Running and jumping is a kind of physical exercise, and it is a periodic physical activity with close cooperation between lower limbs and upper limbs. The purpose of jumping is to strengthen the leg strength and train the coordination of jumping and whole body movements.

When running and jumping, no part of the body should touch the front of the springboard, no part of the body should touch the ground behind the jumper, no jumping off the runway, no somersault, and no contact with the ground outside the landing area (sand pool) when landing. The contact outside the landing area is closer to the jumper than the nearest point in the landing area. After the trial jump is completed, it is not allowed to walk backwards out of the landing area.

There are some difficulties in the implementation of the National Standard for Students' Physical Health: on the one hand, there are few instruments and the test period is long; On the other hand, the accuracy of the instrument is prone to decline. The concrete solution is to solve the step problem by using the steps on the edge of greening, and to teach students to measure pulse, measure steps and calculate indicators.
