1. In assessing muscle strength, we must first understand the relationship that affects muscle strength. The relationship between muscle length and muscle tension is incorrectly stated as follows:
A. Muscle initial length refers to the initial length of the muscle before contraction
B. The longer the initial length is, the greater the muscle strength produced by the muscle generation is
C. If the muscle is contracted, the initial length is in a state of shortening, and the contraction force decreases.
D. If the muscle contraction, the initial length is already in the state of excessive elongation, its contractile force decreases
E. The muscle length-tension relationship refers to the relationship between the initial length of the muscle and the amount of muscle force generated by the contraction
2. The form of muscle contraction includes centripetal and centrifugal contraction, centripetal contraction is also a very common form of contraction in daily life, centripetal contraction is also very common contraction. Characterized by:
A. An increase in the distance between the starting point and the stopping point of a muscle when the muscle is contracted
B. A form of training in plyometrics that produces a centripetal contraction of a muscle
C. Its kinematic function is to produce decelerated motion
D. The contraction of the triceps brachii muscle when the elbow joint is flexed is centripetal
E. The contraction of the quadriceps femoris muscle when the knee is flexed is centripetal
E. The contraction of the quadriceps femoris muscle when the knee is flexed is centrifugal
Flexed. Quadriceps contraction during knee flexion
3. The forms of muscle contraction include centripetal and centrifugal contractions, and centripetal contractions are characterized by:
A. Their kinematic function is to produce primarily accelerated motion
B. Centrifugal contraction of the anterior tibialis muscle during ankle dorsiflexion
C. Centrifugal contractions are a form of training in which a muscle produces a smaller tension
D. Centrifugal contraction is a form of training in which the muscle starts and stops during a The distance between the starting and stopping points of a muscle is passively lengthened during a centrifugal contraction
E. The movement of the body requires only a centrifugal contraction for all movements to be accomplished
4. Assisted training is a commonly used therapeutic technique for plyometrics training in rehabilitation therapy, which is incorrectly described as follows:
A. It refers to the completion of a movement through the patient's active muscular contraction with the assistance of an outside force
p> B. It is suitable for patients with muscle strength class 1 to perform muscle training
C. It is suitable for patients with muscle strength class 2 to perform muscle training
D. It is suitable for patients with muscle strength class 3 to perform muscle training
E. It is suitable for patients with muscle strength class 4 to perform muscle training
5. Active training is a commonly used therapeutic technique for muscle training in rehabilitation therapy, and the characteristics of active training do not include. The characteristics of active training do not include:
A. Active training refers to a training method in which exercise is accomplished through active muscle contraction by the patient
B. Active training exercises do not need to be assisted
C. Active training exercises do not need to overcome external resistance
D. Active training is not suitable for patients with adhesions in their joints
E. Active training is mainly applicable to patients with muscle strength grade 3 or above for muscle strength training
E. Active training is mainly applicable to patients with muscle strength grade 4 or above for muscle strength training
6. Active training is a common treatment technique for muscle strength training in rehabilitation therapy. 6. According to the exertion mode of plyometric training, it is divided into assisted training, active training and resistance training, among which resistance training is the most commonly used, and the characteristics of resistance training do not include:
A. It refers to a kind of training method that needs to overcome external resistance during muscle contraction in order to complete the movement
B. Resistance training is the most effective way to enhance muscle strength
B. Resistance training is the most effective way to enhance muscle strength
D. Patients with joint adhesions are not suitable for active training
C. It should be applied to patients with muscle strength level 3 or above for muscle training
D. Progressive resistance training is a training method that gradually increases the resistance
E. The load is reduced when the muscle strength is increased by progressive resistance training
Reference Answer and Analysis
1. Reference Answer B. Analysis: This question is about the definitional part of the knowledge related to plyometric training. The muscle length-tension relationship refers to the correlation between the initial length of the muscle before contraction and the amount of muscle force produced by the muscle contraction. Only the appropriate initial length, in order to produce the maximum contraction force of the muscle; if the muscle contraction, the initial length has been in the shortening state or excessive elongation state, its contraction force decreased.
2. Reference answer B. Analysis: This question is about the definition of plyometric training part of the knowledge. Centripetal contraction: In plyometric training, the muscle produces a centripetal contraction of a training method. When a muscle contracts, the distance between the starting point and the stopping point of the muscle is shortened, which is called centripetal contraction, and its kinematic function is to produce accelerated movement. For example, biceps contraction during elbow flexion and quadriceps contraction during knee extension.
3. Answer C. Analysis: This question is about the definition of plyometric training. A centrifugal contraction is a type of training in which the distance between the starting and ending points of a muscle is passively lengthened during plyometric training, and the muscle produces greater tension at the same time.
4. Answer E. Analysis: This question is about the definition of plyometric training. Aid training refers to a training method to complete the movement or action through the patient's active muscle contraction with the assistance of external force. It is mainly applicable to patients with muscle strength level 1?3 for muscle strength training.
5. Reference answer D. Analysis: This question is about the definition of plyometric training part of the knowledge. Active training refers to a training method in which movement is accomplished through active muscle contraction by the patient. The exercise does not need to be assisted nor overcome external resistance. It is mainly suitable for plyometric training in patients with muscle strength level 3 or above.
6. Reference answer E. Analysis: This question examines the content of the definition of plyometric training part of the knowledge. Resistance training refers to the patient in the process of muscle contraction, need to overcome external resistance to complete the movement of a training method. Resistance training is most effective in increasing muscle strength. It is primarily used for plyometric training in patients with muscle strength level 3 or higher. Progressive resistance training is a training method that gradually increases resistance, and the load increases as the muscle strength increases.
