Effect of Weight on Climbing
19 Jun 2011
A cyclist weighing 72 kg rode several times a climb of 1 km (105m of difference in height) at increasing average wattages (from 280w up to 400w).
He repeated the same stretch at the same average power outputs, with the addition of 4 kg of scuba weights in his rear jersey pockets.
As we can see from the tab above, the influence of weight is greater when the speed (Vel) is low, probably because of the longer "dead spot" in the pedaling, which translates into a greater deceleration of the cyclist and a subsequent costly acceleration of the body mass.
