3 . Brazil sports are out of control! Brazil may be one of the most sports­crazy countries in the world. Whether you are into watching or playing, Brazil sports have a lot to offer everyone.

Football in Brazil is more than a sport. It's a way of life. Football is popular in Brazil for several reasons. One reason is that it is fast paced and fun to watch. This is the reason why the World Cup Soccer is the most watched sports event in the world aside from the Summer Olympics. Also, you don't need anything to play soccer except for something to kick, and a big area in which to play. Few will argue if you say that Brazil leads the world in football. No nation has won as many world cups as Brazil.

Volleyball is a close second in Brazil sports. In the world of international volleyball, Brazil wins many championships of all kinds, including indoor and beach volleyball. Brazil has nearly 5,000 miles of coastline. If you go to a beach in Brazil, there will always be a volleyball game going on somewhere, and usually two or three.

Footvolley was created in Brazil in the 1960s. It is a mix of football and volleyball, where the players must use their feet and head to get the ball over the net and into the opponents' court, and is also played in sand. It is one of the most popular beach sports in Brazil.

Swimming, tennis, rugby, boxing, judo, sailing, golf, surfing, and handball are all greatly popular in Brazil.

5 . As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

6 . Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact(接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
