Whoa! This was my first reaction when I first saw this video.
The sport being played in the above video is called Sepak Takraw. Since the mid-late 19th century, it's been one of the most popular games in Asia. At first glance, you see a combination of soccer and volleyball. Players are only allowed to use their feet, knees, chest, and head. You can NOT use your hands.
There are only three players on each side of the court at one time. They kick a rattan ball over the net that is generally shorter than the actual player. Each side is awarded a point when either team commits a fault. The first team to 21 points wins.
Can this be a sport we will one day see in the Summer Olympics? If curling can become a Winter sport, I can't see why Sepak Takraw couldn't be considered as a Summer event.
