I’ve been trying to get some info on where peak frequency occurs and maximum velocity occurs for female sprinters. So far I’ve only come up with 40-60m where max velocity occurs but still nothing for peak frequency. I know that Charlie mentions 25-30m for peak frequency for sprinters but I think that he’s mentioning that for males and not females. Seaching the archives for a couple of hours now and I would appreciate any and all help regarding this matter.
I would think It would depend on the top speed of the athlete. Reguardless if the athlete were male or female a 11.0 100 meter runner may reach peak freq. at the same time. And the faster the athlete the longer (distance wise) it would take to reach this peak frequency just like the longer it would take to reach max velocity.
For high developped female sprinters and in normal conditions, in 100m races, this is how things occur: max step frequency, max speed, max step length, male or female. Of course in one example there can be variations, but taking averages for several races that’s the general scheme.
Example, looking at Marion Jones, max frequency occurs between 20m and 40m (or 3 and 5sec), max speed between 40 and 70m (or 5 and 8sec, and max length between 50 and 100m (or 6 and 11sec), depending on the external conditions and physical condition. It isn’t different for other top female sprinters, nor male sprinters actually.
Data from Laser gun at 1997 World Champs in Athens 100m Finals gave the following distance point for max speed:
From this we can say first that men reach max speed after women. But that’s not completely true. Men reach 60.42m after 6.49sec of race, while Women reach 53.73m after 6.48sec. If “After” and “Before” refers to time (not space), then we can say that men and women reach max speed after the same time of race. But as men are faster, the place where it occurs isn’t the same. Unfortunately, the vocabulary for Space and Time is similar, because human spirit can’t make a clear separation between them. Fortunately sprinting does it for us
i thought you might have some data
i was referring to distance, yes; but hadn’t thought the time factor, which is interesting as well! it might be worth adjusting distances accordingly rather than having both males and females run fixed drills…
thanks for this!
