    Effects of Forefoot Shoe on Knee and Ankle Loading during Running in Male Recreational Runners

    Jingying Lu1, Datao Xu1, Wenjing Quan1,2, Julien S. Baker3, Yaodong Gu1,*
    Molecular & Cellular Biomechanics, Vol.19, No.2, pp. 61-75, 2022, DOI:10.32604/mcb.2022.019978
    Abstract Objectives: Although overuse running injury risks for the ankle and knee are high, the effect of different shoe designs on Achilles tendon force (ATF) and Patellofemoral joint contact force (PTF) loading rates are unclear. Therefore, the primary objective of this study was to compare the ATF at the ankle and the PTF and Patellofemoral joint stress force (PP) at the knee using different running shoe designs (forefoot shoes vs. normal shoes). Methods: Fourteen healthy recreational male runners were recruited to run over a force plate under two shoe conditions (forefoot shoes vs. normal shoes). Sagittal plane ankle and knee kinematics… More >

    Numerical Analysis of Blood Flow through COVID-19 Infected Arteries

    Anupam Krishnan1, Anjana P. Anantharaman2,*
    Molecular & Cellular Biomechanics, Vol.19, No.2, pp. 77-88, 2022, DOI:10.32604/mcb.2022.018369
    Abstract Computational Fluid Dynamics has become relevant in the study of hemodynamics, where clinical results are challenging to obtain. This paper discusses a 2-Dimensional transient blood flow analysis through an arterial bifurcation for patients infected with the Coronavirus. The geometry considered is an arterial bifurcation with main stem diameter 3 mm and two outlets. The left outlet (smaller) has a diameter of 1.5 mm and the right outlet (larger), 2 mm. The length of the main stem, left branch and right branch are fixed at 35 mm, 20 mm and 25 mm respectively. Viscosity change that occurs in the blood leads… More >

    Influence of Nutritional Supplementation and Sports Training on the Physical Fitness of Track and Field Athletes

    Wenbing Zhu*
    Molecular & Cellular Biomechanics, Vol.19, No.2, pp. 89-96, 2022, DOI:10.32604/mcb.2022.018522
    Abstract This study aims to understand the influence of nutritional supplementation and sports training on the physical fitness of track and field athletes. Twenty track and field athletes from Chongqing Normal University were supplemented with nutrition and trained for eight weeks. Water, sugar, and vitamins were supplemented. They were trained three times a week, two hours each time. One hour was for special track and field training, and one hour was for physical training. Before and after the experiment, the body composition, sports quality, and functional movement screening (FMS) of the athletes were tested. Compared with before the experiment, the muscle… More >

    Injectable Collagen/CMC Soft Tissue Filler with Developed Flow Properties

    Reza Samanipour1, Aida Pourmostafa2, Adel Marzban2, Sara Tabatabaee3, Hasan Bahraminasab2, Amir Ali Hamidieh4, Amirhossein Tavakoli4,*
    Molecular & Cellular Biomechanics, Vol.19, No.2, pp. 97-104, 2022, DOI:10.32604/mcb.2022.019080
    Abstract Based on the remarkable demand for facial reconstitute or reshape fillers due to the dermal defects arising from specific diseases, trauma, or aging, several natural or synthetic materials have been investigated. Among the evaluated materials, decellularized dermis is one of the most biocompatible choices for the aim of skin tissue regenerative approaches. On the other hand, Carboxymethyl Cellulose (CMC), a synthetic polysaccharide, with the desirable degradability, biomechanical stability, and nontoxicity seems to be an acceptable reinforcement agent for decellularized dermis. Thus, in this research, an injectable soft tissue filler contained of human-derived decellularized collagen and CMC was fabricated. The cell-removal… More >

    A Study on the Effect of Core Strength Strengthening Training on Exercise-Induced Lumbar Injuries

    Xianghui Li*
    Molecular & Cellular Biomechanics, Vol.19, No.2, pp. 105-114, 2022, DOI:10.32604/mcb.2022.018736
    Abstract Objective: This study aims to analyze the effect of core strength strengthening training on exercise-induced lumbar injuries. Methods: Sixteen athletes suffering from lumbar injuries were randomly divided into two groups, group A and group B. Group A performed core strength strengthening training, while group B only performed normal study and life. Before and after the experiment, the Visual Analogue Scale (VAS) score, lumbar spine mobility, Oswestry Disability Index (ODI) and overall effect evaluation of the two groups were recorded and compared. Results: After the experiment, the VAS score of group A decreased to 2.78 ± 1.89 points, the anterior flexion… More >
