Force-Length Analysis

This lecture covers the analysis of active force as a muscle is progressively lengthened, showing how force increases, peaks, and then decreases due to myosin heads losing attachment sites. It also explores passive force behavior, highlighting how muscle relaxation is facilitated by contractions. The lecture delves into representing maximum force, passive behavior, and the relationship between muscle length and force generation. Additionally, it discusses the impact of muscle lengthening on contraction kinetics, revealing that muscle tension affects relaxation difficulty.
