I need to know what happens to the reading on the scale just after i start rising and just before I stop rising. I cannot find our scale so I cannot do this.

Just after you start rising, you will accelerate and the scale will register a higher weight.
Just before you stop, you will decelerate and the scale will register a lower weight.

F = ma
A scale measures force body mass x acceleration due to gravity.
When you go from a squat to a stand you have to accelerate a portion of your bodies mass upward.
The scale reading will increase depending on your mass and the acceleration rate. (how fast you go from a squat to standing)

I agree with roadkill. The momentum will exert a bit of extra force that will increase the number depending on your weight and the speed with which you stand.

Imagine someone squatting on you. Now, they spring upward to full height. Will it hurt more or less when they start to stand up? When they are at full height, what will it feel like?
