Usain Bolt could lose all of his world records if a controversial loophole is exploited by rivals, reports sportbible.com.
 
Bolt won eight Olympic gold medals across three Games in his illustrious career, breaking world records in the 100m, 200m, and the 4x100m.
 
In 2009, he re-broke his own 100m world record, finishing in 9.58 seconds, cementing his status as the fastest man ever. But a former track and field athlete, who is now a college coach, believes there is a way sprinters could save even more time. And he’s spent quite a bit of resources and time explaining why.
 
Omar Bryan believes that the angle athletes have their torso at the start line is decisive.

As the torso is the body part that stops the clock at official competitions, if athletes are able to lean forward with their torso at the start of a race, it could save valuable fractions of a second.

As Olympic sprinters typically take between 43 and 48 strides over 100m, if an athlete leaned forward with their torso by five centimetres at the start, it would save between 0.005 and 0.01 seconds.
 
Put simply, yes. There are no rules over where the torso must be at the start of the race, just that their hands must be behind the line.
 
The World Athletics Competition Rules lay out the specific regulations. Regarding the end of the race, it says: “The athletes shall be placed in the order in which any part of their torso (as distinguished from the head, neck, arms, legs, hands, or feet) reaches the vertical plane of the nearer edge of the finish line.”
 
And in the World Athletics glossary, the torso is defined as the part of the body excluding head, neck, arms, legs, hands and feet.
 
Are there any other advantages for modern athletes?
The Telegraph reported that a laboratory near Cambridge has built the first ‘super track’.
 
The digital ‘smart’ track includes sensors, which will provide data for athletes and coaches. It also has an energy return, which is 20 per cent better than normal running tracks.
   
It has been suggested that its sensors can “provide a raft of real-time data that would be transformative to athletes, coaches, fans and media, but early testing has pointed to an energy return that is some 20 per cent greater than existing tracks.”
