Sprinters closest to starter pistol have advantage over those farther away, says study

On your marks, get set go to lane 1?

Researchers at the University of Alberta in Edmonton studying the connection between loud sounds and reaction time are reporting findings that may have sprinters thinking twice about lane assignments at the upcoming Olympics.

Led by Dave Collins, professor of physical education and recreation, and student Alex Brown, researchers hypothesized that the loud starter's pistol at the Olympic Games would allow racers closer to the starter to react sooner and stronger than runners farther away. By analyzing RT for the 100/110m athletics events at the 2004 Olympics sorted by lane number, they found that runners closest to the starter had significantly lower RT than those further away.

"Whether you're a competitive athlete or just a pedestrian trying to cross a busy street, reaction time can be critical," said Collins. "Past research has shown loud sounds can decrease RT and increase force generated during voluntary contractions, and when those sounds evoke a startle response, RT is decreased even further, which is a good thing."

Collins and Brown, along with Brian Maraj and Zoltan Kenwell, both of the Faculty of Physical Education and Recreation, had four trained sprinters and 12 untrained participants perform sprint starts from starting blocks modified to measure horizontal force. Using a recorded gunshot as the ''go'' signal, they randomly presented the signal to test subjects at various decibel levels, from a low of 80 dB to a high of 120 dB. The louder the gunshot, the faster the reaction time of the test subjects.

"In sprint events, where hundredths of a second can make the difference between a gold medal and a silver, minimizing reaction time can be the key to an athlete's success. We suggest that procedures presently used to start the Olympic sprint events give runners closer to the starter the advantage of hearing the "go" signal louder; consequently, they react sooner than th
