“…It is apparent from our results that the contractile force is much more important than the length in explaining the viscous-like force during the sliding of myofilaments. ABBOTT and WILKIE (1953) and MATSU- MOTO (1967) showed that the force-velocity relationship was valid for all lengths less than Lo. Our results also showed that between 0.8 Lo and 1.2 Lo the dynamic constants remained fixed.…”

Considerable attention has been directed to the characteristic force-velocity relation discovered by A. V. Hill in the study of muscle kinematics. Models of contractile process were tested on the basis of their compatibility with the Hill equation. However, almost all the isotonic data have been restricted to one length, 10, the maximum lengthwith almost no resting tension; the velocities measured are those initial values when the load begins to move. The force-velocity curve extrapolates to zero velocity for isometric tension, but only for the tension at that one length. Very few efforts have been made to study the profiles of the curves throughout the range of lengths over which shortening takes place. In examining the length region, l _< 10, for an isotonically contracting muscle, not only is the force-velocity relation valid for the initial reference length, 10, but also for any other length. The analysis in this report indicates that the constants a/Po and b/lo remain fixed throughout the length change of afterloaded isotonic shortening in the Rana pipiens sartorius muscles. Fenn and Marsh (1935) established the " F e n n effect," Hill suggested that the isotonic force-velocity equation of the striated muscle could be described accurately in terms of a simple hyperbolic relation: I N T R O D U C T I O N 3 yr afterwhere a and b are constants and P0 equals isometric tension at 10. Hill achieved this result by means of study involving heat measurements in the frog sartorius muscles during contraction (A. V. Hill, 1938).Independent of heat data, the force-velocity relation can also be derived from mechanical measurements. This characteristic relation found for mechanical movement, though differing in the time factor, is similar in character II2 5

“…stimulation combined with maximum voluntary dynamic contractions (5). Furthermore, devices have relied on complex servo motors coupled to force transducers that bear little resemblance to human movement pattern (2,11,14,15,16,17,18,19,20,21,22,23,24,25,26).…”

“…A concept well accepted is that force capacity of a muscle force has an inverse non-linear relationship with the speed of shortening (2,3,8,9,10,11,12,13). In an antagonist way, the capacity of power generation increases due to the speed of stretching to a limited extent, mainly when the muscle is stimulated beyond its optimal length (2, 3, 9, 10, 13).…”

These characteristics of plasticity and strength of a muscle when taken as a principle after systematic experimental observations has helped to develop the concepts associated with FD and FE (1,2,11).…”

Introduction:The isometric force history dependence of skeletal muscle has been studied along the last one hundred years. Several theories have been formulated to explain and establish the causes of the phenomenon, but not successfully, as they have not been fully accepted and demonstrated, and much controversy on such a subject still remains. Objective: To present a systematic literature review on the dynamics of the mechanisms of force depression and force enhancement after active shortening and lengthening, respectively, identifying the key variables involved in the phenomenon, and to date to present the main theories and hypothesis developed trying to explaining it. Method: The procedure of literature searching complied the major databases, including articles either, those which directly investigated the phenomena of force depression and force enhancement or those which presented possible causes and mechanisms associated with their respective events, from the earliest studies published until the year of 2010. Results: 97
