    Comparison of Biomechanical Characteristics during the Second Landing Phase in Female Latin Dancers: Evaluation of the Bounce and Side Chasse Step

    Fengfeng Li1, Huiyu Zhou1,2, Datao Xu1, Julien S. Baker3, Yaodong Gu1,*
    Molecular & Cellular Biomechanics, Vol.19, No.3, pp. 115-129, 2022, DOI:10.32604/mcb.2022.022658
    Abstract Research on dance lower extremity joint motion has been limited. Thus, the purpose of this study was to investigate the lower limb biomechanics differences between the side chasse step (SCS) and the bounce step (BS) of the second landing phase in Jive. Thirteen female recreational Latin dancers (Age: 22 ± 2.5 years; Height: 1.65 ± 0.05 m; Weight: 50 ± 4.5 kg; Dance experience: 4 ± 2 years) were involved in the experiment. The same music was used throughout the data collection period. We intended to determine whether these two steps generate different kinematic and kinetic data. The ankle, hip, and knee joint angle, moment, velocity, and… More >

    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 >

    Molecular & Cellular Biomechanics, Vol.19, No.3, pp. 141-149, 2022, DOI:10.32604/mcb.2022.018558
    Abstract This study aims to analyze the difference in biomechanical properties of football players at different levels when kicking the football with the inner edge of the instep. Before the experiment, ten football players were selected; five were higher than the national level (group A), and the other five players were lower than the national level II (group B). 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 >

    Measurement of Myopia and Normal Human Choroidal Thickness Using Spectral Domain Optical Coherence Tomography

    Jia Qin1,2,3,4,5, Lin An1,2,3,4,5,*
    Molecular & Cellular Biomechanics, Vol.19, No.3, pp. 151-157, 2022, DOI:10.32604/mcb.2022.018578
    Abstract Myopia is a common ophthalmic deficiency. The structure and function of choroid layer is assumed to be associated with myopia. In this study, a laboratory developed spectral domain optical coherence tomography scanning system is used to image human eyes. The axial resolution of the system is about 7 μm, and the acquisition rate is 100 kHz. Firstly, a cross-sectional image was acquired by averaging 100 images from imaging posterior segment of each eye. The choroid thickness was measured by 11 discrete points. The average thickness of normal human eyes was (0.296 ± 0.126) mm, whereas the average choroid thickness of… 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.
