To test the hypothesis that sprinters' quickest legitimate reaction times are 100 ms and that there is no gender difference in that time, we examined the fastest reaction times attained by each of the 425 male and female sprinters who competed in the 2008 Beijing Olympics. The results showed that men's fastest reaction time was 100 ms in 11 athletes, women's fastest reaction time was also 100 ms in 11 athletes. The conclusion was that men and women have identical maximum reaction times of 100 ms. This means that if all other factors are equal, men and women would have an equal chance of winning any race between them. However, research has shown that in actual racing situations, other factors such as muscle tone, body type, and training will affect how fast you can react under pressure. For example, if one person is able to relax more than another, they might be able to respond faster to a signal. Also, people with more muscle mass or who practice sports that require speed of movement, such as sprinting, will be able to prepare themselves faster for a competition. Last, individuals who train their reactions skills may be able to respond quicker than those who do not. Overall, your reaction time depends on many different factors.
