The IAAF bans Pistorius from competing at the Summer games in Beijing. Among other findings, it determines that his blades allow him to use 25% less energy than an able-bodied athlete. (Full findings here). Pistorius says he will appeal:
I feel that it is my responsibility, on behalf of other disabled athletes, to stand firm. I will appeal [against] this decision at the highest levels, while also continuing with my quest to race in the Paralympic Games and hopefully the Olympic Games.
