how to design a circuit for convert a 5v dc to 100v impulse. the circuit should be smallest as possible. the output must be an impulse because the circuit is for stimulation of human muscles

This is not a free design service. If you however have a circuit in mind we'd be glad to help you with understanding it.
I'm not going to recommend any specific circuit, but I am going to mention a few important things you need to consider:
The heart is a muscle, you need to make sure your stimulation thingy is not going to stimulate that muscle. You should also avoid stimulating the central nervous center, i.e. the brain and the spine.
I've seen numbers on how much current is required to command muscles but not voltages, and I also know that the skin's resistance can vary a lot. You need to regulate the current.
The circuit needs to be absolutely fool proof:
Continuously zapping a muscle may inhibit the subject from releasing him-/herself from your circuit.
A subject might touch something grounded, you'll need galvanic isolation.
Stick to arms and legs or you might accidentally kill someone.
Limit to one limb at a time, otherwise you might get current through more vital organs, e.g. the heart.
Limit the voltage so that it will be unlikely that it can supply a dangerous current through more than one limbs plus the heart.
And if you don't know what you're doing, please don't connect electricity to someone's body.
