use: can a round ball be used for fitness? Yes, it is a new fitness magic weapon that has swept the world this year. Although it is simple, there are many uses and advantages: it is suitable for almost all people 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 a good auxiliary injury recovery and rehabilitation function, and has a particularly significant curative effect on low back diseases; Moreover, it is safer during exercise and is not prone to injury; At the same time, it can gradually restore and improve the flexibility and balance of people (including patients and injured people), and has the functions of adjusting posture and heart and lung. The fitness ball is made of PVC material with super rubber raw material, which has sponge-like softness, tire-like compression resistance and balloon-like high elasticity, integrates leisure, exercise, weight loss and self-cultivation, is safe and convenient to use, and is a popular fitness product with a brand-new concept. Fitness ball does not require much space, so you can practice freely at home.
generally speaking, there are two kinds of fitness balls, one is a smooth PVC fitness ball, and the other is a foamed PVC fitness ball (that is, a pearlescent explosion-proof ball, also called a pockmarked ball).
the load-bearing capacity of these two balls is the same. At present, the qualified sphere can basically carry 3 kilograms.
the so-called explosion-proof ball means that when the ball hits a sharp object, the ball leaks air. If the gas leaks slowly, the ball becomes an explosion-proof ball. If the gas is deflated in an instant, the human body will immediately fall to the ground. This kind of ball is a non-explosion-proof ball. Some people think that non-explosion-proof means that the ball will explode, which is a misunderstanding.
explosion-proof reason: after PVC is foamed, 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 winding, so the gas can't rush out at once, even if the pressure is high, the slower the gas escapes. If PVC is not foamed, the PVC layer will be hard and firm. Once there is perforation, gas can rush out immediately, and the sphere will become flat immediately, and the human body will easily fall to the ground at once.
in fact, with the development of ball-making technology in recent years, many manufacturers make a smooth surface treatment after PVC foaming, which is a smooth explosion-proof fitness ball, which has both the advantages of smooth ball and explosion-proof ball.
Advantages and disadvantages of non-explosion-proof and explosion-proof balls:
The smooth fitness ball has bright surface and delicious color, which is not easy to get dirty and easy to clean. But some people don't like it very much, because sweat easily adheres 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 the 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 difficult 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 make a smooth surface treatment after PVC foaming, which is a smooth explosion-proof fitness ball, which has both the advantages of smooth ball and explosion-proof ball.
