The Z disk closer together when the position constantly crossing the bridges. The weight pull forced apart from each other by equal forces.

Sarcomeres are the same in the length. When the lower weight of the bridges occurs than the original weight, the sarcomeres get lengthen.

On the other hand when the weight raises the forces than the weight will increase and sarcomere get shorten.
