Is heading in soccer dangerous?
頭球危險嗎？
It's a question that has met its fair share of controversy.
這個問題引發了不少爭議。
If you've never played soccer, heading may look pretty dangerous to the poor brain.
如果你從未踢過足球，頭球看起來對可憐的大腦的確殺傷力很大。
Where else in life do you not wantto duck away from an object flying straight at your head?
如果，生活中的其它時候你看到飛來橫物，你難道沒有躲閃以求護頭？
However, soccer players know thatthere is a proper way to head the ball.
然而，足球運動員是知道頭球路數的。
Yes, there is a technique to meeting a flying ball with your head.
當然，頭球是需要技巧的。
Dr. Frank Webbe, is a formersoccer referee and coach who is also a psychologist specializing in sports psychology.
足球裁判兼教練Frank Webbe在足球心理學上也有研究。
He says there is good reason to believe that with proper technique, a player's risk for brain injury is low.
他說有理由相信有技巧的頭球可以降低大腦受傷的幾率。
The problem is that in a fast-paced game of soccer, obstacles sometimes prevent a player fromheading with good technique.
可問題在于在踢球這個快節奏的運動中，球員頭球的技巧可能會受限制。
And that's when problems are likely to arise.
這也是問題的關鍵。
Webbe and collaborators tested soccer players in neurocognitive performance such as attention,concentration, and speed of thinking.
Webbe和同事測試了足球運動員的神經認知，比如注意力、集中力、思維反應。
They compared long-time soccer players to novices, as well as moderate-to-frequent headers toless than moderate headers.
他們比較了新老足球運動員,較常頭球的球員和較少頭球的球員，
In addition, they tested people who had played soccer recently as wellas people who hadn't played in some time.
最近常常踢球的人和在一段時間內沒有踢球的人。
The results suggested that more frequent headers are at more risk for brain injury than lessfrequent headers.
結果顯示常常頭球的人比較少頭球的人損傷大腦的風險更高。
As a group, frequent headers performed lower on cognition tests in the weekafter a game of frequent heading than did other subjects.
前者總的來說，在長期頭球后的一周內做的認知測試中普遍比后者表現得更差。
Also, players with the highest lifetime estimates of heading scored lowest overall on thesecognition tests.
此外，球員估計在此生中頭球最多的在認知測試中表現最差。
The results convince Webbe that heading does indeed pose a threat to brainfunction and that more research needs to be done.
測試結果足以說服Webbe頭球確實有損大腦功能，需要更多研究加以驗證。
