    Guixue Wang1,2,*

    Molecular & Cellular Biomechanics, Vol.20, No.2, pp. 63-66, 2023, DOI:10.32604/mcb.2023.044564

    Abstract The analysis of biomechanical characteristics plays an important role in mastering the technical characteristics of athletes, providing guidance for the formulation and prevention of sports injury training plans and providing theoretical support for research on injury prevention and stability control in the sports field. With the importance of data analysis, the application scope of artificial intelligence methods is more extensive. For example, intelligent training systems can be used for athletes’ personalized and professional training, real-time monitoring and feedback of training data, and further reduce the risk of sports injury. However, deep learning methods process a large number of medical images… More >

    Effect of a Double Helical Spring Decompression Structure Backpack on the Lumbar Spine Biomechanics of School-Age Children: A Finite Element Study

    Fengping Li1, Dong Sun1,*, Qiaolin Zhang1,2,3, Hairong Chen1,2,3, István Bíró2,3, Zhiyi Zheng4, Yaodong Gu1,*

    Molecular & Cellular Biomechanics, Vol.20, No.1, pp. 35-47, 2023, DOI:10.32604/mcb.2023.041016

    Abstract Background: A children’s backpack is one of the important school supplies for school-age children. Long-term excessive weight can cause spinal deformity that cannot be reversed. This study compared a double helical spring decompression structure backpack (DHSB) with a traditional backpack (TB) to explore the optimization of decompression devices on upper body pressure. The finite element (FE) method was then used to explore the simulation of lumbar stress with different backpacks, in order to prove that DHSB can reduce the influence of backpack weight on lumbar vertebrae, avoid the occurrence of muscle discomfort and spinal deformity in children; Methods: 18 male… More > Graphic Abstract

    Quantification of Ride Comfort Using Musculoskeletal Mathematical Model Considering Vehicle Behavior

    Junya Tanehashi1, Szuchi Chang2, Takahiro Hirosei3, Masaki Izawa2, Aman Goyal2, Ayumi Takahashi4, Kazuhito Misaji4,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.135, No.3, pp. 2287-2306, 2023, DOI:10.32604/cmes.2023.022432

    Abstract This research aims to quantify driver ride comfort due to changes in damper characteristics between comfort mode and sport mode, considering the vehicle’s inertial behavior. The comfort of riding in an automobile has been evaluated in recent years on the basis of a subjective sensory evaluation given by the driver. However, reflecting driving sensations in design work to improve ride comfort is abstract in nature and difficult to express theoretically. Therefore, we evaluated the human body’s effects while driving scientifically by quantifying the driver’s behavior while operating the steering wheel and the behavior of the automobile while in motion using… More > Graphic Abstract

    Biomechanics of transendothelial migration by cancer cells

    CLAUDE VERDIER*

    BIOCELL, Vol.46, No.11, pp. 2381-2386, 2022, DOI:10.32604/biocell.2022.021368

    Abstract Cancer metastasis is still a major social issue with limited knowledge of the formation of tumors and their growth. In addition the formation of metastases is very difficult to understand, since it involves very complex physical mechanisms such as cellular interactions and cell rheology, which are flow-dependent. Previous studies investigated transendothelial migration using sophisticated techniques such as microfluidics, traction force microscopy (TFM) or Atomic Force Microscopy (AFM), combined with physical modeling. Here we summarize recent results and suggest new ways to investigate the precise mechanisms used by cancer cells to undergo transendothelial migration. More >

    A Study on the Importance of Core Strength and Coordination Balance during Basketball Based on Biomechanics

    Yixin Liu*

    Molecular & Cellular Biomechanics, Vol.19, No.3, pp. 131-139, 2022, DOI:10.32604/mcb.2022.019342

    Abstract When basketball players play against each other in a game, better coordinated balance can give them a better advantage. This paper briefly introduces the coordination balance and core strength of basketball players. Twenty basketball varsity members were selected from Chengdu College of University of Electronic Science and Technology of China as subjects for the test. The athletes were randomly divided into a control group and an experimental group. The control group received regular strength training, and the experimental group received core strength training in addition to regular training. Both groups underwent isometric muscle strength test, coordination and balance test and… More >

    A New Approach through the Eye of a Needle and Its Potential Application in Bioscience

    Hongfang Song1,2, Aike Qiao3,4,*

    Molecular & Cellular Biomechanics, Vol.19, No.3, pp. 159-164, 2022, DOI:10.32604/mcb.2022.019005

    Abstract Putting the thread through the eye of a needle is a very ordinary issues in daily life. The mechanism of putting the thread through the eye of a needle is quite similar to threading a series of polymer chains through synthetic macrocycle in bioscience. A new rubbing approach to thread through the eye of a needle was proposed in this paper, and its potential application in the fields of biomechanics and mechanobiology to mimic the micro scale assembly processes was discussed.

During the experiment, the motion process was captured by a high-speed camera for biomechanical analysis. It was found that in group A, the thigh and leg swung in less time and larger amplitude, the acceleration of backswing and forward swing of the… More >
