Abstract: nanomaterials have been widely used in sports stadiums, sports turf, athletics track, sports apparel, sports equipment and sports supplements. nanomaterials, however, may have a negative impact on cell lung tissue, liver tissue and brain tissue. Actually, there is a certain biological security risk in it. When the full use of nanomaterials in sports are been taken, the positive effects of development projects and biological research on nanomaterials should be emphasized.

Abstract: Kaedah A is a fend off technique engaged in Seni Silat Cekak Malaysia, upon confronting a punch force exerted within the vicinity of the thorax area. Hitherto, there is still lack of biomechanical analysis on the execution of Kaedah A. Therefore, this study aims at analysing the effectiveness of Kaedah A based on the total execution time as well as to describe the kinematic characteristics of the hand movement upon its execution. The experiment was carried out by means of motion capture. Microsoft Kinect was utilised to detect the hand movement whilst the post processing of the captured motion was performed via Virtual Sensei Lite. Kaedah A was executed five times by an experienced Seni Silat Cekak Malaysia practitioner to investigate the accuracy and repeatability of the system. The data obtained serves as an input for the trajectory mapping for both initial and end point identification. The time difference, Δt between the points demonstrates that the total time execution for Kaedah A is less than 0.1 s. Further analysis involves filtering the coordinate data obtained in order to generate the polynomial function of the hand movement during the execution of Kaedah A. It could be concluded that the Kaedah A execution has the features of a ballistic movement. The findings provides useful data for reliability prediction as well as further enhancement of the Kaedah A itself.

Abstract: Nanomaterials have widely been applied in sports engineering, such as sports stadiums, field turf, tracks, sports-wears, equipments and supplements. Inevitably, nanomaterials may cause some potential adverse effects on the cells, lung, liver, kidney, and brain, respectively. Nanmaterials have been fully used in sports fields, and its biosafety should also be focused.

Abstract: The applications of advanced materials in the sports Engineering are the long-term needs of sports development. The roles of the advanced materials played to improve relations between the level of science and technology and the sports Engineering are elaborated, the applications of the new materials at home and abroad are introduced in the paper, pointing out that the development of sports needs people to explore and use new materials, and the research and application of new materials have great significance on the development of sports.

Abstract: Functional properties of nanophase materials are different from conventional materials, which determined the related technology for the rapid development and wide application space. Nanophase materials have been widely used in sports stadiums, sports turf, athletics track, sports clothing, sports equipment and sports supplements, and so on. At the same time, there may be a negative effect of nanophase materials on cell, lung, liver, kidney and brain. Therefore, the biological study of nanophase materials should also be strengthening.

Abstract: This paper aims to define sports engineering through the use of historical and contemporary examples. The historical development of the technology in the sprint and in the javelin are discussed, from their introduction to the Olympics over two and a half thousand years ago to the current day. The rules pertaining to tennis racquets are described and the ways in which manufacturers and researchers attempt to maximize performance using technology are examined. Two models for a tennis racquet are shown, one in which the racquet is modelled as a rigid body and one in which it is modelled as a flexible beam. Use of the models shows that further advances in racquet technology using stiffer and lighter materials are unlikely to speed the game up. It was concluded that technology can be used by athletes and manufacturers to enhance performance. Equally, the ruling bodies of sport can also use technology to limit performance, leading to a delicate balance between technology and tradition.
