Development of methods for running and long jumping biomechanics analyses in elite Paralympic athletes
No full textSport activity can be beneficial for all aspects of life, from physical to mental health, whatever level it is practiced. Sport promotes social integration, both for able-bodied people and, even more so, for people with disabilities. Therefore, it could be essential to understand how the sport gesture is performed, in order to ensure the athletes’ safety. In case of athletes with lower limb amputations, research is ongoing to investigate new technologies that could be used to mimic the lost anatomical limb.
In this perspective, the Department of Industrial Engineering (DII) of the University of Padova and INAIL (Italian National Institute for Insurance against Accidents at Work) carried out a collaboration whose aim was to study new technologies at the service of elite Paralympic athletes during sprinting and long jumping activities. Nine athletes from the Italian Paralympic team were involved in this study. They were transfemoral and transtibial unilateral amputee athletes competing in the 100 m, 200 m and long jump events.
It is well known that lower-limb amputation leads to an asymmetry between limbs. The study of the biomechanical parameters could therefore provide a better understanding of the compensatory strategies that athletes with amputations use to replace the loss of the anatomical limb.
The aim of this work was the development of instrumentation and methods to collect and analyse data for a better understanding of running and long jumping biomechanics. The purpose of all these analyses is to gain a better comprehension of how different Running Specific Prosthesis (RSP) affect the biomechanics of running and long jumping.
Significant time was spent to develop a 3D motion capture protocol to be used for unilateral transfemoral and transtibial amputee athletes. In addition, the protocol could be adjusted to be used also for able-bodied and bilateral lower-limb amputee athletes. Furthermore, effort was made to implement the spring-mass model in case of lower-limb amputation with reference to the study of Liew et al. (2017). Finally, different software packages were developed to perform biomechanical analyses. The biomechanical tool allows standard and more specific analysis to
be performed.
Several sprinting and long jumping test sessions were collected in an indoor field track using nine force platforms and ten optoelectronic cameras. During the tests, athletes changed different socket alignments and Running Prosthetic Feet (RPF) varying the stiffness category or the RPF model. Analysis of data collection was performed. However, the results are preliminary, as the data collection was intended to assess reliability of these methods and the athletes‘ Olympic preparation, rather than a full insight into RSPs’ effects on biomechanics.
To conclude, the developed methods represent the starting point for further analysis regarding the effects of different Running Specific Prosthesis on running and long jumping biomechanics

No full textTHE INFLUENCE OF THE COMPETITIVE ENVIRONMENT ON THE COMPANIES COMPETITIVENESS
No full textIn a market economy, competition is the engine which makes the entire system of connections between the economic operators work, the main element of the market mechanism which leads to the development of the economic life. The competition represents a tough fight, without considerations, where the economic interests of each participant on the market come first. In this context, this paper attempts to carry out an analysis of the competitive environment and especially of the influence exerted by it on the competitiveness of the companies. Otherwise, competitiveness can be regarded as the main goal that is to earn higher profits or a better position on the market.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Towards a Wearable System for Complete Collection of Clamp Loads in Transfemoral Paralympic Sprinters
No full textBiomechanical analysis of paralympic amputee sprinters has implications for the design of prosthetic components and for the improvement of the athletic performance. Thus, the purpose of this study was to carry out the kinetic analysis of a unilateral transfemoral amputee sprinter running on track through measurement of reaction forces and inertial data with a wearable acquisition system. The outcomes here presented find agreement with literature findings and, on top of that, add new information that strengthen knowledge in the prosthetic field and can be used for future works
