"&lt;p&gt;&lt;/p&gt;&lt;p&gt;LONDON (AP) -- Taekwondo officials are changing the rules to protect fighters from the impact of head kicks.&lt;/p&gt;&lt;p&gt;   At the London Olympics, fighters will score points for head kicks as soon as any part of their foot touches their opponent's head - without regard for impact, as was previously the case.&lt;/p&gt;&lt;p&gt;   World Taekwondo Federation sports director Jeongkang Seo says the change will make scoring more uniform and encourage athletes to try for more head kicks without demanding extreme force.&lt;/p&gt;&lt;p&gt;   The change will likely have little effect on head kicks that most often result in knockouts, since those usually involve a spinning technique that are almost always delivered with significant power.&lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
