Matters needing attention

Exercise should improve your ability and avoid injury. Warm-up and stretching are just like the basic internal skills in martial arts novels, so we must persevere and be down-to-earth. But many people only know one, don't know the other, or can't grasp the essentials; Not benefit from it, but suffer from it; Therefore, in order to get the maximum benefit from the tie-wraps and ensure safety, the following principles must be observed:

1. Be sure to warm up before tying your shoelaces; For example, using a small run to raise the body temperature, so that the muscles and tendons are in a state of preparation, the effect of lacing will be improved, and the chance of injury due to improper lacing can also be reduced.

2. Don't pause breathing when stretching tendons; Take a deep breath slowly; Pause and hold your breath, it will increase negative oxygen debt, uncoordinated movements, and increase the chance of laceration injury.

3. Stretch tendons before and after exercise; Most people only remember to stretch tendons before exercise; Tired after exercise, I don't want to move even; In fact, after exercise, although the muscles are sore, it is still necessary to gently do lacing again, so that the muscle fibers can be re-conditioned, the speed of fatigue recovery will be accelerated, and the muscle state will be better next time.

4. The lacing action should be slow and gentle, and it is forbidden to use force too hard or too hard. The purpose of lacing is to stimulate the nerve information of muscle spindle nerve and tendon sensory corpuscle by using the elasticity and extensibility of tendon, and gradually increase the stretching potential and endurance. Whether it is rhythmic or fixed (more than 30 seconds in a row), it is effective as long as it is moderate; The most taboo is the tendons that can't be pulled and pressed normally. In order to be quick, they are pressed by violence, or others apply external help; As long as the force is improper, it will cause harm.
