Research shows men kick the soccer ball differently than women. The study, published this month in the Journal of Bone and Joint Surgery, finds males activate certain hip and leg muscles more than females during the most common soccer kicks – the instep and side-foot kicks. While men activate more muscles, the data may explain why female players are twice as likely as male players to sustain anterior cruciate ligament (ACL) injury.
“By analyzing the detailed motion of a soccer kick in progress, our goal was to home in on some of the differences between the sexes and how they may relate to injury risk,” said orthopaedic surgeon Robert H. Brophy, MD, the study author and assistant professor of orthopedics at Washington University School of Medicine in St. Louis. Read the rest of this entry »

How many calls came into question during the recent World Cup competition in South Africa? In just about every competitive sport, referees must call who crossed the line first, or if the ball was inside or outside of a line. Many sports have addressed the issue. Tennis uses a Hawk-Eye technology that films and replays the ball play in question. Cycling uses cameras on the finish line and transponders on each bike. Football draws a digital line in the replay to measure the ball and distance it’s traveled. More technology is on the way.

One thing was proven at this year’s World Cup tournament: you need to have eyes like a hawk to keep track of the ball. That’s why Dr. Paul Hawkin, inventor of Hawk-Eye, is pushing for adopting of his tracking system by the International Football Association Board. If adopted this could see the use of goal-line watching technology put in place this year.
Hawkins isn’t new to the world of sports either, and he previously developed the ball-tracking device used in cricket, snooker and tennis, and is pushing for similar technology to be used in football/soccer. The system includes six cameras facing the goal from different angles to track the ball, where a signal is transmitted via a bank of computers to a referee with half a second of the ball crossing the line. Given some of the disputed calls during the World Cup, this could make a huge difference.
However, not all are in embracing the idea. It has been noted that many English Premier League matches are carried by Sky TV, which has eight cameras on the field, so a simple replay should often be enough to determine a call. But the real question is whether you can ever really have enough eyes – Hawk – or otherwise watching the action?

adidas World Cup Jabulani Ball
This week the California Institute of Technology gave new meaning to the concept of “air ball” as aerospace engineers at the prestigious school put the controversial new “Jabulani” football (that’s soccer to most of us Americans) to the test in a wind tunnel. The ball, which was developed by adidas, is currently being used in the World Cup, where players, coaches and fans have blamed it for missed shots. So much for blaming bad play?
According to reports two balls were put into the Lucas Wind Tunnel and exposed to wind speeds of about 10 meters per second, which is actually slower than a typical kicked ball. To determine the movement of air around said balls, a smoke machine was called in. This helped the engineers visualize the air movement. The findings actually matched some complaints from teams in the World Cup. The ball reportedly had some “bizarre trajectories.”
Developed by the adidas Innovation Team (a.i.t.), the ball has been tested as new “match ball” for the 2010 FIFA World Cup in South Africa. This mean tests under the toughest laboratory conditions, but it isn’t clear if this is in fact the first time the ball went into a wind tunnel. At this point it doesn’t look as if the ball will pulled, but with more studies coming dare we say that the wind of change is blowing through.

These players are kicking on a hybrid natural grass and artificial turf.
Field caretakers at this year’s World Cup may get a break from patching grass at this tournament. The fields are sewn with reinforced natural grass produced by Belgian-based company Desso Sports Systems. An article appearing in USAToday details “a surface with 20 million threads of synthetic grass fibers woven in between and beneath the natural grass.” The surface is far from Astroturf of yesterday. Natural grass composes most of the playing field, but is reinforced with artificial threads driven eight inches into the surface and intertwined with the roots of the real grass to keep the field intact for the long series of soccer games to be played.
The enhanced surface is already installed in a number of fields worldwide. For soccer, or football as the rest of the world calls it, Arsenal and Liverpool in the U.K. and the training grounds of Real Madrid. For American football, the Denver Broncos and the Philadelphia Eagles already use the reinforced natural grass.

The heart rate monitor and GPS device is no longer personal for world football players. Australia’s World Cup players are picking up data via satellite for each player’s workout. Teams get competitive data on their own performance, and their competitors, according to “Socceroos go high-tech to gain an edge over rest of the world,” an article published in The Sydney Morning Herald.
Players down under were able to compare their training to that of their Russian counterparts. Team coaches also use the data to provide support for their players. “We’re analyzing the players’ volumes of sweat and composition so we can accurately predict how much fluid they’ll lose during a game and at training,” Australia’s strength and conditioning coach Darren Burgess told the paper. “We want to have a rehydration strategy for each player.”
It will be interesting to see what other teams and leagues pick up this method of training. Will it lead to real-time data access to personal workouts instead of uploading details upon return from a run?

Nike makes team uniforms from recycled plastic bottles.
The recent trend in sports and fitness clothing is green, sustainability. Nike is part of this trend and especially when it comes to football (that’s soccer to many of you), and the upcoming 2010 World Cup in South Africa. This year Nike is outfitting the Brazil team with home and away kits, plus eight away kits for other Nike-sponsored federations appearing in the games. What’s so sustainable about these kits or outfits you ask? Nike’s fabric suppliers sourced plastic bottles from landfill sites in Japan and Taiwan to produce the jerseys and shorts.
Eight plastic bottles produce one jersey. To turn bottle into soft, breathable fabric bottles the manufacturer melts the plastics down to produce new yarn and then convert that yarn into fabric to construct jerseys. Just because the jerseys are made from plastic doesn’t mean players will drown in their own sweat. Designed to keep players drier, cooler, and more comfortable, the outfit has a handful of features. The Dri-Fit fabric is 15 percent lighter than previous Nike kit fabrications, which also benefits players’ ability to do their stuff out on the field. The coordinating shorts have additional ventilation zones below the waistband and near the base of the spine to keep the outfit breathable.
The outfits have some protection built in as well. Nike Pro Combat, adds protection against light impact and abrasion in the Slider and Impact shorts. The Pro Combat also features a therma Mock that protects a player’s neck against harsh conditions such as sun.
The process saves raw materials and reduces energy consumption by up to 30 percent compared to the manufacture of virgin polyester. For the upcoming season and competition, Nike salvaged roughly 13 million plastic bottles, totaling around 254,000 kg of polyester waste from landfill sites. That’s enough to stretch a distance of 3,000 kilometers if the bottles are laid out end-to-end.
The games take place in South Africa with teams from Brazil, The Netherlands, Portugal, U.S.A., South Korea, Australia, New Zealand, Serbia, and Slovenia. Get your own team kits at nike.com and nikefootball.com.
