Compilation of written exercises for physical education examinations in middle and high schools in national teacher recruitment

In the recruitment examination of physical education teachers, especially in senior high school, the content of sports events is often examined, which is difficult for candidates to understand and is also a difficult point in the examination. Let's try to make some basic choices and fill in the blanks.

example

1. When kicking the ball on the instep, () muscles contract explosively.

A. rectus abdominis B. quadriceps femoris C. Gastrocnemius D. Gluteus maximus

1. Answer B. Analysis: Develop the strength of hip flexors and knee extensors when kicking the ball on the instep. That is, the strength of muscles such as iliopsoas and quadriceps femoris (almost fixed).

2. Kicking mainly exercises () muscle strength.

A. rectus abdominis and gracilis B. rectus abdominis and posterior thigh muscles

C. iliopsoas and rectus femoris D. medial and lateral femur

2. Answer C. Analysis: The iliopsoas muscle is the active muscle of hip flexion, and the rectus femoris muscle can bend the thigh at the hip joint, so the iliopsoas muscle and rectus femoris muscle are mainly developed for kicking. The gracilis muscle is located in the superficial layer of the inner thigh, and when contracted near the fixed position, the thigh can be adducted at the hip joint.

3. Among the following options, the one that does not belong to the typical symptom of meniscus injury of knee joint is ().

A. there is obvious tenderness in the knee joint. B. swelling of the knee joint.

C. The knee tendon reflex disappears and the leg is forced to bend. D. quadriceps femoris muscular atrophy

3. Answer C. Analysis: The typical symptoms of meniscus injury of knee joint are joint swelling, pain, quadriceps muscular atrophy, tenderness, joint locking, snapping and joint instability.

4. What are the characteristics of the body shape of the athletes in the body-oriented strength events? ( )

A. Arm length B. Hip

C. Muscle fiber D. All the above statements are correct

4. Answer C. Analysis: Physical exercise can increase muscle volume. The increase of muscle volume is due to the thickening of muscle fibers. The main reason of muscle fiber thickening is that the internal structure of muscle fiber has changed. Therefore, this question chooses C.

5. When hypoglycemia occurs, the first thing that is affected is ().

A. myocardial contractility B. transport of blood oxygen C. skeletal muscle D. brain and sympathetic nerve

5. Answer D. Analysis: Blood sugar is the main energy source of brain cells, so the influence of hypoglycemia on the body is mainly the nervous system, especially the brain and/or sympathetic nerve. Severe and long-term hypoglycemia attacks can cause a wide range of nervous system diseases.
