Fitness, originally for the purpose of "fitness" but not familiar with the use of fitness equipment, or without supervision and guidance, the use of heavy weight, there will be such a dilemma - not fitness first hurt.
The weight-bearing belt is recognized as one of the most important fitness equipment. Weight-bearing belt can not only strengthen the strength, but also provide you with the necessary protection against sports injury, especially for the lumbar spine. Timing: only when heavy weight training is used. In particular, those exercises are directly applied to the spine, such as squat, push and bend.
There is evidence that waistbands also contribute to the development of strength in the core area of the body rather than hinder it. One study found that abdominal muscle activity increased by 10% during stretching, while another recorded a 23% increase in erector muscle activity during squatting. Not only that, it has the following functions:
First, pressure. Apply some pressure to the muscles to adjust the balance of the force. To a certain extent, strengthen muscle strength. Muscles are stimulated during exercise, and the amount of water in the muscle cells increases, causing the cells to feel swollen. Proper pressure exertion helps to make the exercise more relaxed and powerful, and to find the feeling more easily.
Second, support. Rigid waist protector can provide a certain amount of support in the course of exercise, holding the bending of the waist too large, alleviating the muscles suffered inside, to protect the waist will not sprain or pain. Certain functional waist protectors have metal sheets attached to the back, which can effectively provide greater support and avoid accidental injury. This kind of waist protector is generally higher at the back.
Third, keep warm. The double layer or multi-layer material has soft and comfortable waist and has a strong thermal insulation function. Athletes in sports often wear less, and waist heat more, easy to catch cold, make people back acid, spasm or cause stomach discomfort. Heat preservation performance waist protection can effectively maintain waist temperature, accelerate blood circulation, prevent colds and stomach discomfort.
Fourth, body building. Strengthening cell metabolism, burning fat, regulating tightness, and applying appropriate pressure can help weight loss and body building. In doing waist-related exercises, pressure, heat preservation and sweat absorption waist protector can speed up fat decomposition, is a necessary waist fitness equipment.
Years of fitness, the protection of the fragile lumbar vertebra is absolutely a major event can not be ignored, or wait until the time of lumbar injury to regret. Novice should do a good job for their own body protection, in order to keep fit but hurt the body on the contrary!
