The soccer is the world's most popular and widely watched game. Due to increasing technological advancement and demand for performance, the ball manufacturers have been developing new designs progressively. A traditional spherical football made of 32 leather panels stitched together in 1970s has become only 14 synthetic curved panels thermally bonded without stitches ball in 2006 and more recently 8 panels football in 2010. Despite being most popular game in the world, scan data is available on aerodynamic properties of footballs especially Jabulani, Teamgeist and Fevernova balls. The primary objectives of this study were to evaluate aerodynamic performances of these three soccer balls. The aerodynamic forces and moments were measured experimentally for a range of wind speeds. The aerodynamic forces and their non-dimensional coefficients were determined and compared.
When any object goes through the air, a thin cushion of air wraps around it that stays relatively still. This boundary layer is why you get dust trapped on your ceiling fan. At slower speeds, the air around a soccer ball moves smoothly over the surface and separates off the sides of the ball at its widest points. Imagine a ball moving from right to left across a clock, Goff explains, so traveling from the 3 to the 9. With laminar flow, the air flows over the surface and then flows off at the 12 and 6, which creates more drag in the air. Drag slows the ball down faster. At higher speeds, the air moves turbulently across the ball’s surface and peels off at the 2 and 4. The wind effectively wraps around the back. This turbulent flow has less drag, which means the ball keeps moving at high speed for longer.
Trendy names, fancy designs, and higher prices don't necessarily mean some soccer balls are better than others. Don't fall for advertising hype. A moderately-priced soccer ball might perform and hold up just as well as the one that costs three times as much. With today's advanced technologies and materials replacing good old-fashioned leather, there are many soft and durable, lightweight synthetic soccer balls that may just as well suite you, in fact leather soccer balls are no long the norm since they tend to absorb moisture. There are also things you can do to extend the life of your new soccer ball, such as storing it correctly, cleaning it, and using it properly. But the mark of a truly sweet soccer ball comes down to feel and performance, which is highly individual.
Another replica ball, the Adidas MLS TOP Glider is the exact copy of the match ball which used in the Major League Soccer. For enhanced visibility, this ball is designed in alternating colours so that the footballers can see it from long away. And when it is available in three stylish colour contrasts, everyone can purchase it as per his personal choice.
When it comes to the training soccer ball, it can be purchased at a much-reduced price as compared to the actual match-ball. Incorporating inferior quality materials in its construction, this is an ideal equipment for the sake of training. So if you’re looking for any such ball to sharpen your skills, have a look at the Adidas Champion’s League Finale Capitano Soccer Ball.
For those taking their game to the next level, it’s important to train with a ball similar to what is used for your matches. Your passing, shooting and general foot skills will be different for lighter soccer balls made with a premium bladder like latex. Try out an NFHS approved ball which is used for some club, high school, and college teams. To be NFHS approved, the soccer ball needs to:
