Bodysurfing is related to riding on a wave with no help from aid tools such as a surfboard. That’s why it is called the “purest” form of surfing. In fact, it is one of very few extreme sports—free climbing and cliff diving are. others—that can be practiced using nothing but the human body.
How do you do it?
To catch a wave, swim to where the waves break and, as one approaches, start swimming towards the beach. You must try to travel at the same speed as the wave and, if you do it correctly, you will feel the wave lifting you and pushing you forwards. Then try and cut along the surface of the wave.
What do you need?
It is more enjoyable and safer if you use flippers (large flat rubber shoes). This is because they enable you to swim faster and surf along them more easily. A wetsuit is also advisable. Another aid is a handboard, a mini-surf board about the size of an iron, held in one hand to speed up along the wave. If you are lucky enough to be surfing in warm water, make sure you have your boardshorts at the ready.
Unofficial world championship
Bodysurfing is not a professional sport, but in Hawaii there is such a festival called the Pipeline Bodysurfing Classic each year. Local bodysurfers compete against athletes from places such as Australia, Brazil, Japan or France. Famous bodyboarder Mike Stewart has won the event no fewer than 12 times, and Kelly Slater, the greatest surfer in history, has also competed.

2 . Exercise could not only benefit your body, but also improve your memory, researchers found recently. In their paper published on Monday, researchers from the University of California, Irvine in the United States and the University of Tsukuba in Japan introduced their experiment and conclusion.
Scientists invited 36 volunteers who were in their early 20s to do 10 minutes of light exercise before taking a memory test in which they were shown pictures like broccoli（西兰花）or picnic baskets and asked to recall them later. The same experiment was repeated with the same group of volunteers without exercising. u The memory task was really quite challenging , " said Michael Yassa,co-author of the study and a neuroscientist （神经科学家）at the University of California, Irvine. "We used very tricky similar items to see if they would remember whether it was this exact picnic basket versus （对抗）that picnic basket. "
Researchers also scanned brains of some, of the participants during the experiment. They found strengthened communication between regions involved in the storage and recollection of memories in brains of those who had exercised. This suggested that just 10 minutes of light exercise like walking,yoga or Tai Chi might increase memory power.
As all the volunteers in the experiment were relatively young, researchers are still working to look at the effects of light exercise on older people. "Our future goal is to try to develop an exercise prescription（处方） that can be used by older adults who might have disabilities or mobility impairments,but can still adopt very simple exercise rules of life and be able to,perhaps,delay cognitive decline temporarily," said Yassa.
