Stumbled upon a thread on another site where a commenter was saying that he can sprint faster by not swaying the bike side-to-side, thus taking a straighter overall line.
In practice, this would appear like a Cat. 5 newbie standing out of the saddle with arms and elbows locked, bobbing up and down frantically as they surge towards the finish line.
I think the guy is missing the point of why you get out of the saddle when sprinting but perhaps I'm the the one in the wrong. In theory, the guy isn't necessarily wrong as a straight line path for the wheels seems like the best approach.
But, swaying the bike under your body allows you to leverage your own body weight into each down-stroke combined with even more power being generated by your arms and upper-body muscles. Utilizing so many muscle groups at one time takes an enormous amount more energy which is why your heart-rate and breathing quicken and you can't sustain it for long.
Thus, while the wheels may not be taking the shortest path to the finish line, the increase power being generated while out of the saddle and swaying the bike back and forth more than compensates for the additional distance the wheels travel.
Am I wrong?
