“…He attributed this behaviour to internal viscosity and experimented with visco-elastic model systems, but despaired of a quantitative solution to the problem. Later authors (Banus & Zetlin, 1938;Buchthal, Kaiser & Rosenfalck, 1951;Hill, 1952) have shown that the stress-strain curve is, to a first approximation, exponential. The time-dependent property has been analysed in two ways: either by supposing that the resting muscle contains a number of linearly damped elements with different time constants (Buchthal et al 1951;Abbott & Lowy, 1957), or that it can be treated as a single damped element with highly non-linear properties (Stacy, 1957).…”

“…Studies have long shown that the passive resistive forces of skeletal muscles increase in a curvilinear manner as the muscle-tendon unit (MTU) is stretched from a shortened length to its maximal length (Brodie 1895;Haycraft 1904;Banus and Zetlin 1938;Tabary et al 1972Tabary et al , 1976Williams and Goldspink 1978). Investigations have shown that a combination of anatomical structures are responsible for this curvilinear increase.…”

Viscoelastic properties of short calf muscle-tendon units of older women: effects of slow and fast passive dorsiflexion stretches in vivo

Changes in connective tissues of the skeletal muscle-tendon unit (MTU) of aging animal muscles have been associated with increased passive viscoelastic properties. This study examined whether similar changes in the viscoelastic properties were present in short calf MTUs of older women in vivo. Fifteen women 68-87 years of age with short calf MTUs, as represented by limited active dorsiflexion (DF) range of motion (ROM) of < or =5 degrees, and 15 women 20-26 years of age without decreased DF ROM participated. A Kin-Com dynamometer stretched the MTU from plantarflexion to maximal DF at the slow velocity of 5 degrees s(-1) (0.087 rad s(-1)) and the fast velocity of 120 degrees s(-1) (2.094 rad s(-1)) with minimal surface electromyogram activity in the soleus, gastrocnemius, and tibialis anterior muscles. Two-way analysis of variance (ANOVA) tests for repeated measures (Velocity x Group) indicated that all women showed greater passive torque, average passive elastic stiffness, and total absorbed passive elastic energy for the fast stretch than for the slow stretch (P < 0.001). The older women had greater percent increases for the average passive torque (30%) and total absorbed passive elastic energy (26%) for the fast stretch than the younger women (P < 0.05), who had 17.5 and 13% increases, respectively. The older women had less maximal and average passive torque (Nm) and total absorbed passive elastic energy (degrees Nm), but greater average passive elastic stiffness (Nm degrees (-1)) at both stretch velocities (P < 0.001). The results indicated that short calf MTUs of older women have increased passive viscoelastic properties that could have implications for balance and ambulatory function.

“…However, this cannot be the cause of the discrepancy in the many experiments performed on frog's muscle. In some cases disagreement is explained by the use of twitches instead of tetani (Reichel, 1936;Banus & Zetlin, 1938); in others the explanation is obscure (Rosenblueth, Alanis & Rubio, 1958). Some authors have attributed Blix's minimum to the effects of fatigue (e.g.…”

“…The division of total tension into an active and a resting part implies that these tensions are borne by elements that are separate in a mechanical, if not in an anatomical, sense; the experiments of Banus & Zetlin (1938) showed this to be at least a good approximation.…”

The mechanical properties of the semitendinosus muscle at lengths greater than its length in the body

As Blix knew in 1895, the total tetanic tension of frog's muscle passes through a maximum at a certain resting length L', near to the body length Lo. At lengths greater than L' tension decreases through a minimum, then rises again. Blix remarks that 'the relation disclosed here gives support to the idea, which has been proposed many times, that the force of contraction depends on the attraction between longitudinal tissue structures within the muscle, which are set apart by extension and in this way weaken the attraction'. The discovery of two separate sets of A and I filaments (Hanson & Huxley, 1953) and the demonstration that the A bands do not change in width during passive stretch or active shortening of muscle fibres (Huxley & Niedergerke, 1958) provided the structural basis for a revival of this type of theory of muscle contraction (e.g. Huxley, 1957). It is natural to suppose that the shear force between actin and myosin filaments, and thus the tension developed by the whole muscle, should be a function of the area of overlap of the two types of filaments; the decrease of tension development with increase in muscle length, which proved a stumbling block to many visco-elastic theories, is then readily explained. It also seems natural to suppose that other phenomena of contraction should be similar functions of the area of overlap. The purpose of this paper is to examine the mechanical properties of whole living muscles over the range of lengths beyond L', where the isometric tension diminishes with increasing muscle length and to answer the following questions:(1) Does tension fall when the active muscle is stretched beyond L'? (2) Does tension rise, then fall again, if the active muscle is allowed to shorten at constant speed through L'? (3) Is the relation between force and speed of contraction affected beyond L'2? And (4) is the total amount of shortening against a given load altered if contraction begins from beyond L'?
