How to increase the speed of 100 meters

I can, give me the opening format.

The so-called sprint must have speed, and running fast is inseparable from two factors, one is the size of the pace, the other is the pace frequency, both of which are big, your sprint performance is very good, and the report also revolves around the physical fitness of the athlete, so you must understand the physical fitness of the athlete, as long as you write around these, you will be able to write a good report.

The ability to run fast.

a) Corners start 30 to 60 meters of various sections of running.

2) Straight - Curve - Straight Run 200 300 meters. It is required to start the body to the tangent square of the curve, and at the same time it is required to run out of the curve at a very fast speed, and when entering the straight, run 3 or 4 steps naturally by inertia, so that the body changes from leaning inward to running in a straight line, and then naturally accelerates to run 30 40 meters.

3) Stride jumping practice followed by acceleration running, which requires that the joints should be fully opened when doing stride jumps, and no twisting and cutting movements should be done. Studies have shown that in addition to supporting the ground, the legs are also in the air during running, and the legs also occupy a certain amount of time in the air. Therefore, stride jumping is an effective means to solve the problem of too long time in the air.

4) Kick the back leg to practice acceleration running, requiring the upper and lower legs to be folded naturally and as close to the buttocks as possible. Develop strength in the hamstring muscles of the thigh. Increase the swing radius of the leg while increasing the swing speed of the leg.

5) Raise the legs to practice the acceleration run, fold the big and small legs and lift them up as much as possible, and actively press down when they reach the highest point. Running with high leg lifts can help students experience and master the movement technique of pushing and swinging with both legs in sprinting, and also develop the strength of thigh flexion and extension muscles.

6) Running in small steps to practice accelerated running, the upper and lower limbs naturally cooperate, and the joints of the lower limbs are naturally relaxed, and the frequency should be fast.

The above auxiliary exercises are designed according to the movement trajectory of the legs during the running process, requiring students to experience the relaxation of the knee and ankle joints and the organic connection of all aspects of running on the way during the exercise, and at the same time run more quickly.

7) Short-distance sprints, usually 30 meters, 50 meters, 60 meters, 80 meters, the intensity is controlled between 85 and 95, and the interval between groups and each time is a little longer, so that students can have sufficient rest.

8) Acceleration run 20 30 meters followed by a relaxed Youxiang inertia running practice without deceleration.

Elementary school students can do this with their mathematical thinking skills

How to develop students' problem-solving skills?

1) Improve the quantity and quality of students' knowledge reserves.

help students retain knowledge firmly; A variety of variants are provided to facilitate the generalization of knowledge.

Include; Pay attention to the connection between knowledge and establish a network structure.

2) Teach and train problem-solving methods and strategies.

Combined with specific disciplines, teaching thinking methods; Externalize ideas and teach explicitly.

3) Provide a variety of opportunities to practice.

4) Develop the habit of thinking about problems.

Encourage students to take the initiative to identify problems; Encourage students to come up with hypotheses from multiple perspectives.

degree of analysis of problem solving; Encourage self-evaluation and reflection, and 4) train students' thinking skills.

It depends on how well you know your topic, how well you understand the proposal report, and how much time you spend reading the materials and literature you are looking for. These can determine the speed.
