“…This reinforces the association between large speed, the amount of shortening and force produced during shortening, and the magnitude of the FD to be partly dependent on the elongation vs shortening cycle to stop the phenomenon (6,7,32,33).…”

“…Literature data point to the idea that the intensity of the decline of isometric force is directly influenced by the extent of muscle shortening, the shortening speed and the amount of force produced during the shortening phase (2,6,7,14,15,16,33). This can be seen in the summary of the studies shown in Table 1, which also shows that the employed force control, in most studies, is made by frequency of the stimulation produced in the sarcomere, or to muscle fiber.…”

“…Relevant fact is that the phenomenon has a greater duration than five seconds (2,6,33,40,41), considered expressive by the investigator of such subject. Moreover, the FD cannot be completely eliminated after a maneuver of muscle relaxation by deactivation nor manipulated by shortening with fast speed, preceded by a shortening with slow and steady speed, which would result in a reduction of the isometric force to zero (6,7,15,42).…”

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

Dynamic human body models in vehicle safety: An overview

et al. 2023

View full text Add to dashboard Cite

Significant trends in the vehicle industry are autonomous driving, micromobility, electrification and the increased use of shared mobility solutions. These new vehicle automation and mobility classes lead to a larger number of occupant positions, interiors and load directions. As safety systems interact with and protect occupants, it is essential to place the human, with its variability and vulnerability, at the center of the design and operation of these systems. Digital human body models (HBMs) can help meet these requirements and are therefore increasingly being integrated into the development of new vehicle models. This contribution provides an overview of current HBMs and their applications in vehicle safety in different driving modes. The authors briefly introduce the underlying mathematical methods and present a selection of HBMs to the reader. An overview table with guideline values for simulation times, common applications and available variants of the models is provided. To provide insight into the broad application of HBMs, the authors present three case studies in the field of vehicle safety: (i) in‐crash finite element simulations and injuries of riders on a motorcycle; (ii) scenario‐based assessment of the active pre‐crash behavior of occupants with the Madymo multibody HBM; (iii) prediction of human behavior in a take‐over scenario using the EMMA model.
