Speed does not change the weight -- which in this case is #m*g = 67 kg*9.8 m/s^2 = 656.6 N#

Explanation:

You may think that at the moments that both feet are off the ground the weight should be zero. But no, the force that is your weight is the reason you come back down.

I hope this helps,
Steve
