Abstract Age-related loss of foot intrinsic muscle (FIM) strength may be associated with disability, falls, and inability to perform daily activities. Previous studies have determined the reliability of FIM strength testing and evaluated the relationship between FIM strength and corresponding muscle morphology in young adults. However, few studies have measured FIM strength in the older. Therefore, this study aimed to assess the intra- and inter-reliability of FIM strength tests and the relationship between FIM strength and FIM size in the older. A total of 61 participants aged 60–75 years were recruited, and 18 of them were selected randomly for the verification… More > Graphic Abstract

Abstract The properties of polyurethane concrete containing a large amount of fly ash are investigated, and accordingly, a model is introduced to account for the influence of fly ash fineness, water ratio, and loss of ignition (LOI) on its mechanical performances. This research shows that, after optimization, the concrete has a compressive strength of 20.8 MPa, a flexural strength of 3.4 MPa, and a compressive modulus of elasticity of 19.2 GPa. The main factor influencing 28 and 90 d compressive strength is fly ash content, water-binder ratio, and early strength agent content. More >

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 >
