Isokinetic strength training method

Although we have been doing exercise since childhood, exercise is not as simple as we think. Many sports have their own effects and contraindications. Therefore, when we exercise, it is best to find out what these effects and contraindications are. This can also help us solve many problems. So what is the isokinetic strength training method? Let’s take a look at it together next.

1. Definition: A muscle strength training method that achieves a constant angular velocity on a special isokinetic trainer, that is, the movement speed remains unchanged during training, but the resistance encountered varies with the degree of force applied, so as to keep the muscle tension of the moving limbs at the optimal state.

2. Indications and contraindications

(1) Indications: muscle atrophy caused by immobilization, reduced movement or other reasons, muscle atrophy caused by muscle disease, muscle dysfunction caused by neuropathy, muscle weakness caused by joint disease or injury, muscle dysfunction, and muscle strength training for healthy people or athletes.

(2) Contraindications: joint instability, new fracture or incompletely healed fracture, acute inflammation or infection (redness and swelling), severe pain or hematoma during joint movement or muscle extension, bone and joint tumors, poor general condition, and unstable condition.

3. Equipment and tools: Isokinetic training apparatus.

4. Operation methods and steps

(1) Before training: Turn on the machine and install the corresponding training equipment according to the training requirements.

(2) Position the patient and secure him/her securely.

(3) Joint motion angle setting: Usually the entire joint motion angle can be set. For the early stages of muscle, tendon, and ligament healing, after joint surgery, or when there is a joint disease, it is advisable to limit the range of joint motion.

(4) Training methods: divided into isokinetic concentric training and isokinetic eccentric training. Movement speed: usually includes 60, 120, 180 degrees/second or 60, 120, 240 degrees/second, and the maximum speed can be increased to 720 degrees/second according to training needs. The training program can also be set to 8 to 10 speeds, increasing or decreasing by 20 or 30 degrees/second.

(5) Number of training sessions: It is recommended to repeat the exercise 10 times at each speed. The intensity of the exercise, interval time, and frequency of training can also be determined based on the goal of increasing muscle strength or developing muscle endurance.

5. Notes

(1) Before maximum load isokinetic training, low- or medium-load exercise should be performed.

(2) Perform small-angle exercises before full-angle exercises.

(3) Concentric isokinetic exercise should be performed before eccentric isokinetic exercise to help patients better master the technique of exerting force.

Because during centrifugal exercise, the speed of movement often comes from the robotic arm rather than the patient himself.

(4) For other precautions, please refer to “Isotonic Muscle Training”.

Although the isokinetic strength training method is somewhat difficult to understand, if we spend time and energy to understand it, we can learn a lot of knowledge from it. Of course, there are many issues to pay attention to in isokinetic strength training. We should not let ourselves get injured because of exercise. This is a more serious consequence for us, and of course we are unwilling to accept it.
