How do elementary school students jump high and jump far???

High Jump for Elementary School Students:

Depending on the different types of high jump, there are two basic essentials:

1. The essentials of leapfrogging high jump: the running action is easy, natural and elastic, the last step is slightly smaller, and the speed is fast; Jump, quickly push and extend the hips, knees, and ankles, and fully extend the torso. Highlights: A combination of run-up and take-off.

2. The essentials of the back-to-back high jump: run-up: straight line arc wheel Li line, arc run-up outside the front foot of the front foot of the palm of the calendar to the ground, swing the shoulder height and lead the jump side shoulder, lean inward, and accelerate the jump after two steps;

Jump: The penultimate step adopts a "hard brace" rapid swing, the swing leg is slightly bent and swinged inward, the knee is inward than the ankle, the swing side hip is higher than the jumping side hip, the starting leg is actively on the ground, and the shoulder side is facing away from the crossbar.

Over the bar: Hit the head and spine axially above the crossbar, and after the head passes the bar. The arms are also lowered from the top of the shoulders to the sides of the body, and when the chest is over the pole, the hips are actively pushed upward, the calves are relaxed and drooping, and the pole becomes a "bridge" action.

Landing: After the thighs cross the bar, shake the calves with the thighs and calves, bow your head and bend your shoulders, stretch your knees and shoulders and carry the pad. Highlights:

A technique that combines run-ups and take-offs.

Since the body of primary school students is still in the stage of growth and development, the practice of high jump must pay attention to the gradual step-by-step, and must not be in a hurry, otherwise the damage to the body is relatively large.

1. What are the benefits of long jump?Frequent long jump is very meaningful for us to refresh our spirits and relieve fatigue, now many people will have a very troubled situation, at this time in fact, our best antidote is exercise, you can use this method to relieve stress, so if we feel that our troubles are very much, at this time we had better do more exercise, less use of the brain, which can help us to relieve the problem of stress, is a good choice for everyone to rejuvenate the spirit.

2. What are the benefits of long jumping, which promotes heart health?

We can also help promote our heart health through long jumping, which is good for promoting myocardial perfusion, and can also help us reduce the incidence of stroke in men through long jumping, which is very good for everyone's health. Therefore, we should insist on going to the long jump in normal times, which can be very helpful to our health and is a good choice for everyone to prevent heart disease.

3. What are the benefits of long jumping?

** Bodybuilding, improves insulin resistance. A study in the United States confirmed that the body's energy expenditure is inversely proportional to the development of type 2 diabetes, and that walking at an agile and active pace for 1 hour a day can reduce the occurrence of type 2 diabetes by half, and the lowest risk is for those who use aerobic exercise and calisthenics. In fact, the long jump is also good for us, it is an effective way for everyone to maintain a good body shape, and we can also use the long jump method to help us effectively improve the situation of insulin insufficiency, which is meaningful for us to protect cardiovascular health.

Leapfrogging High Jump is a class in the fifth grade of elementary school.

According to nine years of compulsory education.

Primary 5 "Physical Education and Health".

The leapfrog high jump consists of four parts: running, jumping, flying over the pole, and landing. Questions for a lesson: preferred, determine the starting point; Secondly, low height, cross the bar in situ, feel the bar and the vertical Zheng landing action, and finally, start practicing from no height, and gradually increase the height.

Brief introduction. Through nearly a month of teaching practice, the students in the class they taught understood and mastered the leapfrog high jump. In education and teaching, advanced educational concepts are used.

and scientific teaching methods.

Strive to cultivate students' sense of cooperation and competition, choose teaching methods that can stimulate students' interest in learning and promote students' thinking activities, and pay attention to teaching students according to their aptitude and people.

It effectively mobilizes the initiative of students to learn, so that students gradually develop a good habit of serious study in the classroom, so that every student can practice in "music", practice "music", the classroom atmosphere is full of vitality, and effectively improve the quality of classroom teaching. In my survey of fifth-grade students, almost everyone can actively participate in teaching activities emotionally and in action, so that everyone participates in activities and develops healthily.

Methods of high jump for primary school students: back-to-back high jump technique, folding running technique, leapfrog high jump technique.

1. Back jumping skills.

The main feature of the back-to-back high jump run-up is the arc run-up, and the run-up line is generally "j", and its advantages are:

1. The preparatory section of the run-up is a straight line or a line with a small curvature, so it is easy to accelerate and exert speed throughout the whole process.

2. The transition to the arc is relatively smooth and natural, which can avoid pause or deceleration.

3. The curvature of the arc changes from large to small, so that the body gradually increases the internal frequency.

4. The last step is about 20 degrees to 30 degrees angle with the crossbar to ensure that the human body has a suitable vertical displacement distance relative to the crossbar after vacating.

2. Folding running technology.

The task of the run-up is to achieve the necessary horizontal speed and create the conditions for an improved take-off and a smooth crossing of the crossbar. The back-to-back high jump generally uses 8 to 12 steps to run, which is divided into a straight line and an arc run.

1. Straight-line running technique: similar to the short-circuit running technique, the center of gravity of the body is high and stable when running, the upper body is appropriately leaned forward, the back pedal is full and powerful, the forward swing is actively lifted by the legs, and the arms are coordinated and swing greatly.

2. Arc running technique: the body is gradually tilted inward, increasing the swing amplitude of the outer leg arm, and keeping the head and torso in a straight line to lean inward. The whole process of running should have obvious acceleration and a strong sense of rhythm, especially the last few steps gradually accelerated, to the last step is the fastest.

3. Leapfrogging high jump skills.

Leapfrog high jump action method: slash run, jump with the sole of the foot on the ground, swing the leg up, swing the arm quickly, lean forward with the upper body, lean the thigh against the chest, swing the leg after the rod turns down and presses down, the jumping leg is raised, the swing leg lands on the ground first, and the knee is bent to cushion.

Action method: step up and jump after running in a straight line, the two arms and swing legs swing quickly, and the jumping legs are fully extended; After crossing the bar, swing the leg to the ground first, bend the knee to cushion.

Action points: the running action is relaxed, natural and elastic, the last step is slightly smaller, and the speed is fast; Jump, quickly push and extend the hips, knees, and ankles, and fully extend the torso.

1. Run-up. Start running in a straight line, with your shoulders drooping and your forefeet on the ground, so that you can run elastically; Raise the center of gravity, noisy and vertical disturbance stride evenly, and continue to accelerate; During the run-up, the arms should swing back and forth actively and vigorously, and the swing amplitude of the outer arm should be greater than that of the inner arm when running in an arc.

2. Take off. Landing of the jumping leg, cushioning and pushing and extension techniques: To speed up the take-off, the jumping leg should land on the outside of the ball of the foot sharply and smoothly, and quickly roll from the heel to the ball of the foot.

When the body turns from tilting to perpendicular to the center of gravity of the body to the top of the jumping leg, quickly and forcefully straighten the three joints of the jumping leg, and the torso stands almost vertically on the jumping foot in an instant before leaving the ground;

Coordination and coordination technique of swinging leg and arms during take-off: the arm farther away from the crossbar during take-off swings the neck upward, plus one arm does not swing out fully, and brakes early. The swing of the swing leg should start from the side of the jump leg with the knee bent, lead with the knee, bend the knee first, fold the knee, and swing vigorously above the distal pillar of the rear jump overhead;

3. Crossing the pole and landing. When crossing the bar, immediately bend the hips and abdomen, quickly lead the lower jaw to the chest, and at the same time raise the two calves compensally and actively shake the slim upwards, the head can not be tilted back, and the eyes must always be fixed on the direction of the crossbar.

Long jump skills: 1. Pre-swing: open your feet left and right, shoulder width apart, swing your arms back and forth, swing your legs straight when swinging forward, bend your knees to lower your center of gravity, lean your upper body slightly forward, and swing your hands back as much as possible.

Key points: The upper and lower limbs are coordinated and coordinated, the center of gravity is lowered by one extension and two flexion when swinging, and the upper body is slightly leaning forward.

2. Take off and take off: kick the ground quickly and hard with both feet, and swing from back to front and top with both arms slightly bent, jump forward and upward in the air, and fully extend the body.

Key points: Kick the ground quickly and powerfully, the leg pedal and the hand swing should be coordinated, the aerial body should be sufficient, and the forefoot before leaving the ground should be emphasized to push the ground instantaneously.

3. Landing buffer: Tuck the abdomen and raise the legs, stretch the calves forward, swing the arms back at the same time, and bend the knees to drop the chain without slowing down the buffer.

Key points: Grasp the timing of the calf extension, bend the leg and extend the arm back, and go forward and not backward after landing.
