The above calculations use the 100,200,400 meter age factors in Table 3 in Fair (2004). They are based on pooling the 100, 200, and 400 meter track events. The data are only for men. These age factors should be used for 100, 200, and 400 meters. The swimming results in the paper suggest that women slow down a little faster than men, which if true, means that the following age factors are a little too low for women. The age factors are:
