    • A sphere provided with an air chamber of a diameter of approximately 20-23 cm and equipped with a special valve to ensure that the air pressure, once inflated, is maintained properly. The exterior material of the air chamber is of synthetic canvas or other material like silicon rubber and has 24 conical protrusion of 2,3 to 3 cm in hight, and seperated from each other by about 8 cm. The diameter of the sphere will be of cm. The weight of the sphere may be varied according to the need, by changing the fibers of the construction. It may also be realized in different colors. The sphere, due to the protrusions and their numbers, acquires a dynamicbouncing behaviour. leading to increasing challenge for the reflexes of the players and the improvement of physical force due to the unpredictable bounce of the sphere.
    • 球体设有直径大约为20-23厘米的空气室,并装有特殊的阀门,以确保一旦充气过程中的空气压力正常保持。 空气室的外部材料是合成帆布或其他材料如硅橡胶,并且具有高度为2,3至3厘米的24个锥形突起,并且彼此分开约8厘米。 球体的直径为cm。 根据需要可以改变球体的重量,通过改变结构的纤维。 也可以用不同的颜色来实现。 由于突起及其数量,球体获得动态弹跳行为。 导致球员的反射增加的挑战和由于球体的不可预测的反弹而改善的身体力量。
