“…We performed the experiments on rat (Rattus norvegicus, Wistar) M. gastrocnemius medialis (GM; n¼9, m GM ¼ 8217 100 mg, mean 7 standard deviation (SD), Table 1). The experimental setup was described in detail previously in the literature, and we refer the interested reader to Siebert et al (2014b) and Till et al (2008).…”

“…Furthermore, kinesio taping can influence passive muscle shape and architecture (Pamuk and Yucesoy, 2015) and change at least the initial conditions of a contraction. On the other hand, transversal compressive forces that do not necessarily require structural continuity with the muscle belly to be transmitted can lead to a decrease in longitudinal muscle force, and this decrease is of the same order of magnitude as the transversal load (Siebert et al, 2014b).…”

“…Application of local transversal pressures in these ranges (1.3-5.3 N cm −2 ) induced by a plunger on rat M. gastrocnemius medialis resulted in a reduction of muscle forces by 5-13% (Siebert et al, 2014b). These results suggest that the observed IrMP between rabbit GAS and PLA can reduce the muscle force produced by both muscles during contraction.…”

“…Isometric experiments with and without transversal muscle loading (contact area: 0.5 cm 2 ) on rat M. gastrocnemius medialis demonstrated that, compared with an unloaded situation, the maximum isometric force and the rate of force development were reduced by 4.8% to 12.8% and 20.2% to 34.6%, respectively, at pressures ranging from 1.3 to 5.3 N cm −2 (Siebert et al, 2014b). Although these studies provided evidence that transversal muscle loading has an impact on contraction dynamics, only limited conclusions regarding the situation in vivo could be drawn.…”

The purpose of the study was to examine the relationship between muscle force generated during isometric contractions (i.e. at a constant muscle-tendon unit length) and the intermuscular (between adjacent muscles) pressure in synergistic muscles. Therefore, the pressure at the contact area of the gastrocnemius and plantaris muscle was measured synchronously to the force of the whole calf musculature in the rabbit species Oryctolagus cuniculus. Similar results were obtained when using a conductive pressure sensor, or a fibre-optic pressure transducer connected to a waterfilled balloon. Both methods revealed a strong linear relationship between force and pressure in the ascending limb of the force-length relationship. The shape of the measured force-time and pressuretime traces was almost identical for each contraction (r=0.97). Intermuscular pressure ranged between 100 and 700 mbar (70,000 Pa) for forces up to 287 N. These pressures are similar to previous (intramuscular) recordings within skeletal muscles of different vertebrate species. Furthermore, our results suggest that the rise in intermuscular pressure during contraction may reduce the force production in muscle packages (compartments).

The dynamics of the skeletal muscle: A systems biophysics perspective on muscle modeling with the focus on Hill‐type muscle models

Skeletal muscle is one of the most fascinating and crucial ingredients of motion generation in nature. Since the beginning of science, people dedicate their life as researchers to enhance knowledge about this biological motor. Thus, the scientific knowledge about the skeletal muscle is overwhelmingly broad and detailed. This contribution collects knowledge about the active and passive dynamics of skeletal muscle. Furthermore, it highlights a special perspective in which not only the muscle itself, but also the role muscles play in the interaction with other structures is studied. The first section introduces this systems biophysics perspective, which clusters the investigation of the relations, interactions and dependencies between muscles and the other structures in the movement apparatus. In the second section, the muscles are considered in more detail by describing three approaches to muscle modeling. The third section deals with recent advances based on Hill‐type models, such as, for example, the integration of mass.
