Purpose: Can the ball be used for fitness? Yes, it is the new magic weapon that swept the world this year. Although simple, it has many uses and advantages: it is suitable for almost everyone to exercise, including those who need rehabilitation treatment; Its fitness effect is good, especially beneficial to the exercise of spine and pelvis; It also has good auxiliary injury recovery and rehabilitation functions, especially for low back pain diseases; Moreover, it is safer during exercise and is not easy to get hurt; At the same time, it can gradually restore and improve the flexibility and balance of people (including patients and injured people), and has the function of adjusting posture and heart and lungs. The fitness ball is made of PVC material and super rubber material, which has sponge-like softness, tire-like compression resistance and balloon-like high elasticity, integrates leisure, exercise, weight loss and self-cultivation, and is safe and convenient to use. It is a mass fitness product with a brand-new concept. Fitness balls don't need much space, so you can practice freely at home.
Generally speaking, there are two kinds of fitness balls, one is PVC smooth fitness ball, and the other is PVC foaming fitness ball (also known as pearlescent explosion-proof ball, also called pockmarked ball).
These two kinds of balls have the same bearing capacity. At present, the qualified sphere can basically carry 300 kilograms.
The so-called explosion-proof ball means that when the ball hits a sharp object, the ball will leak air. If the gas leaks slowly, the ball becomes an explosion-proof ball If the gas deflates instantly, the human body will fall to the ground immediately. This kind of ball is a non-explosion-proof ball. Some people think that it is a misunderstanding that the ball will explode if it is not explosion-proof.
Explosion-proof reason: after PVC foaming, many irregular fibers will be produced on the surface of PVC, which will be softer and thicker. If the gas wants to pass through this layer, the walking path is tortuous, so it is impossible for the gas to rush out at once. Even if the pressure is high, the gas will escape more slowly. If PVC does not foam, the PVC layer will be very hard and firm. Once there is a perforation, the gas can rush out immediately, and the sphere will flatten immediately, making it easy for the human body to fall to the ground at once.
In fact, with the development of ball-making technology in recent years, many manufacturers have done smooth treatment after PVC foaming, that is, smooth explosion-proof fitness ball, which has the advantages of both smooth ball and explosion-proof ball.
Advantages and disadvantages of non-explosion-proof and explosion-proof balls;
The smooth fitness ball has bright surface, delicious color, not easy to get dirty and easy to clean. But some people don't like it very much, because sweat is easy to attach to the surface of the sphere. You can cover the sphere with a yoga towel, which can solve the problem of tax-included adhesion.
Although the surface of explosion-proof ball is pearlescent, the color is dark and not bright enough, and there are many pits on the surface, which are easy to stick to dust and not easy to clean. But sweat is not easy to adhere to the surface of the sphere, and the sphere is soft and elastic.
In fact, with the development of ball-making technology in recent years, many manufacturers have done smooth treatment after PVC foaming, that is, smooth explosion-proof fitness ball, which has the advantages of both smooth ball and explosion-proof ball.
