If you are able to speed up on rollers by 'pumping" them IE them aggressively sucking up the frontside and pressing down the back side. couldnt you slow by resisting when you are flexing?
wouldnt the same work for mogul skiing?
Yes, you can slow yourself down by resisting the pressure build up by extending squarely, not flexing, into the mogul face as I have attempted to describe a few times. The skier finishes the turn by driving into, through and over the mogul face, then as soon as the boots are near or at the high point of the mogul face, the skier retracts/flexes to get the ski shovels back in contact with the snow to initiate the next turn. There is also some speed control gained with brushing at the finish of this turn.
TDK6 created the time frame sequence, he said he could see the skiers knees flex slightly when going up the mogul face and determined it was flexion. I tried to explain that the skier was consciously extending into the mogul face and any knee flex was the result of pressure build up/load as the skier was actually resisting this pressure, not intentionally flexing the knees to get over the mogul face.
