Abstract
(6 figures) Frog sartorius muscles are stretched at rest and during maximal tetanic contractions. Parallel compliance decreases when the length increases. The relationship between compliance and length is linear in double-logarithmic scale. The compliance of the active muscle (tetanic contraction) is not related to the length. The series-compliance is calculated from the parallel compliance and the active one. It increases with the length of muscle. These results are discussed on the basis of the sliding-filaments theory.
