Bola Sepak Latihan Anak Football Light Learning Ball Size 4 Blue Green

8753544 We have designed this Learning Ball especially for kids. It #39;s lighter than a traditional football, making it easier for kids to learn to play. Learning to kick a ball and get it off the ground is not as easy as it looks. That #39;s why we created this ball, which is 15% lighter than traditional balls. Durability TPU outer layer to withstand wear. Lasting air retention Optimised bladder for good air retention. Reduced impact Lighter ball with foam-padded panels for a more comfortable game. Bounce The ball meets international football standards in terms of bounce. Lighter than a regular ball This ball is considered light because it is about 15% lighter than a regular size 4 football. What difference does that make? Thanks to its weight, young football players can kick or head the ball more comfortably. It #39;s also easier to aim, do long passes and score goals.A guaranteed hit! Too light? Too heavy? The weight is standardised... The weight of this ball is between 280 g and 300 g compared with 350 g and 390 g for a traditional size 4 football. How big is it? What #39;s the circumference? This ball measures between 63.5 cm and 66.0 cm (size 4). A round ball? We measure the football #39;s sphericity at 4500 different points and then examine any differences. If the discrepancy is greater than 1,8% (FIFA PRO Standard), our engineers are tasked with improving the sphericity to ensure a consistent bounce. We inflate the ball to the recommended pressure (meaning 0.8 bar). 72 hours later, the ball must not lose more than 15% of its pressure, meaning approx. 0.1 bar. The pressure after 72 hours must, therefore, be at approx. 0.7 bar. This also means that it is quite normal for a ball to lose pressure after a few days.
