![]() Then, using results from our earlier lab study which measured lower extremity reactions, we calculated that by reducing the force threshold for women at the Olympics by 21 percent, the reaction gap should disappear. They replied that information was proprietary. Once you realized what might be causing the difference in women versus men’s reaction times, what step did you take?Īshton-Miller: Prior to publishing that article, we reached out to Omega to ask what force threshold they used on their starting blocks and whether it was the same for men and women. That would mean that the sex difference in reaction time was likely an artifact. Eventually, based on our lab study, we speculated that Omega sister company Swiss Timing (the official Olympic timekeeper) must have used the same force level on the starting blocks for men and women in determining whether a false start had taken place. Our analysis showing slower reaction times by women in Beijing surprised us, but initially we accepted the finding. If the blocks register a certain level of force before 100 milliseconds has elapsed after the starting gun, it is deemed a false start. When the athlete adopts their starting position, one foot goes against each plate and, in order to accelerate forward, the athlete has to push off against these instrumented blocks. Now, both plates on the starting blocks at the Olympics are equipped with a force sensor. ![]() But if a much larger force was required to register reaction, then it took women longer than men to reach that threshold. Those data unequivocally showed that for small forces, women reacted faster than men. What troubled you about your own findings in that paper?Īshton-Miller: It happens that, as part of a previous study on the biomechanics of falls, our team measured lower extremity reaction times in a lab. ![]() Those data indicated that female sprinters had slower reaction times than their male counterparts. A paper you published in 2011 analyzed data compiled during the 2008 Summer Olympics in Beijing from track and field events. His latest work provides insights into what may, or may not, have happened since.Īshton-Miller is the Albert Schultz Collegiate Research Professor & Distinguished Research Scientist in mechanical engineering and biomedical engineering. It did not accurately detect false starts by women. In 2011, James Ashton-Miller, a Michigan Engineer, helped reveal that Olympic starting-line technology created a different experience for male and female sprinters.
