1. Diaphragmatic length–tension curve in normal hamsters and hamsters with elastase-induced emphysema. Tension is expressed as a percentage of maximum tetanic tension, PO, and length is expressed as a percentage of original optimal length, LO. The degree of filament overlap among actin (A) and myosin (M) filaments in control (A), acute (B), and chronic hyperinflation (C) is shown. Note that due to sarcomere adaptation in chronic hyperinflation, the degree of filament overlap is the same at a considerably shorter length.
