Unless you are running completely retarded,‘tweaking your mechanics’ is not going to improve your speed across the ground all that much.
Srsly bro, hang on a monkey bar and pedal your legs in the air as fast as possible…DAMN UR PRETTY FAST. U GOT GOOD TURNOVER.
What would this indicate(?)
1Amount of force put against the ground with your foot >> 2turnover > 3technique
1Get a higher strength/weight ratio >> 2work on speed stuff > 3be mindful of good technique
It’s true the speed of your legs traveling through the air when you run will not be significantly slower than that of say Usain Bolt and what will differentiate you is the fact that
- His foot contact time will be significantly less than yours.
- His stride length will be significanlty longer than yours, helped of course because he is 1.96m or 6 foot 5.
His ground reaction force will be much greater resulting from the faster generation of force. So yes it all comes down to his power generation. Now to say speed isn’t an issue may be pushing it too far. Have you ever tried running down a slight hill or tried running on a track with spikes after months of training on grass? your legs struggle to keep up.
Please don’t underestimate the benefits of technique. Good technique is purely positioning the body in its best possible position so that the majority of the forces generated from your legs/body are transfered into the ground and not wasted through unnecessary movements and poor stride length. To put it into a weightlifters terminology it would be like trying to deadlift with the bar say several inches or a foot infront of your shins. Sure if you were stronger you could lift more but without doing it properly you will be lifting well below what you are capable.
And believe me the technique of the majority of non professional sportsmen/footballers is somewhat short of optimum.
