[quote author="Nick Newman" date="1259215455"]I’ve played around with fly 10m, 20m and 30m going max frequency a few times and then max stride length a few times and i find there is no difference in times…I think SR is therefore over rated…lol
Bolt @9.59 and 40 strides= 4.1x
Average Joe Sprinter at 11.9 and 49 strides = 4.1x
I like focusing on stride length and mechanics vs. frequency. Complete your strides and stay in position. Longer stride with shorter contact=faster runs. i[/quote]
Ito & Kaneko (1988) showed that the freely chosen stride length is where the sprinter produces the greatest power; any shorter or longer and it has a detrimental effect on maximum speed. The chosen measurement parameters of stride length and stride rate are only indicative of underlying mechanisms. The mechanisms that produce stride length we understand better and so can achieve more improvement in. The mechanisms that improve stride rate are so not well understood at high speed not to mention difficult to achieve absolute improvements in.
Mr. Octane… count how many steps you take in 30-m and divide it by your 30-m time. This will give an average stride rate although that rate changes over the 30-m. If you are far from the average Joe then you will need to improve.
Also I mentioned hip flexion work not neccessarily because it relates to stride rate but simply because it has been proven to provide substantial increases in sprint acceleration for relatively untrained people. However my position always is that the closer the specificity to the sprinting movement, velocity, and time of contraction (and sequence of recruitment) used in training the greater the absolute improvement.
