BIOMECHANICAL FACTORS TO BE TAKEN INTO ACCOUNT TO PREVENT INJURIES AND IMPROVE SPORTING PERFORMANCE ON ARTIFICIAL TURF
2009
This article reviews existing knowledge concerning the epidemiology, instruments and regulatory criteria currently used to evaluate artificial turf soccer pitches. Recent years have seen tremendous growth in the use of artificial turf as a playing surface for sports (rugby, soccer, American football…) and the problems traditionally associated with artificial turf and its relationship with a higher percentage of injuries seem to be disappearing. The contribution of biomechanics to the development of new techniques and instruments for analysing the properties and characteristics of grass pitches has contributed towards close collaboration with the regulatory bodies of different sporting organ…

Effect of Foot Orthoses and Shoes in Parkinson's Disease Patients : A PRISMA Systematic Review
2021
[Abstract] Reduced plantar foot sensation, postural instability, and gait difficulties are characteristic of Parkinson´s disease patients. A systematic review was carried out to determine the effect of the different types of insoles and shoes in these patients. Several databases were used to search for relevant articles reporting Parkinson´s disease patients undergoing treatment with any type of insole and footwear. All titles and abstracts were reviewed independently by two reviewers and the available data were extracted. The study eligibility criteria were any type of experimental study that included Parkinson’s disease patients treated with any type of insole or footwear. Eight studies w…
Improvement of balance in a 7-year-old child through a six-week learning programme
2018
Given that human beings are constantly subjected to equilibration processes, developing basic perceptual motor skills, especially balance, is important. The main purpose of this study is the validation of the tasks and the progression of activities that form the learning programme for balance development in a six-week didactic unit of 12 sessions (2 sessions per week), for 6 to 9 year old children (1st, 2nd, and 3rd grade of elementary school in Brazil). The changes in balance after applying the programme are also analysed through a new measuring protocol using baropodometry. Although the session was put into practice in a class of 28 children, data were extracted from a 7-year-old child. T…
Use of the electronic baropodometer (EBP) to study dysmetria of the lower limbs: A case report
2001
An electronic baropodometer was used to study a case of lower limb dysmetria caused by an accident with delayed functional recovery of gait. A static baropodometric test of the patient without shoes and without orthesis revealed plantar imprints with loads within the norm; a static test with shoes but without orthesis showed that the operated right foot carried 42% of the body weight and the pressure peak M was on the second left metatarsal head, while the pressure centres of the individual plantar ("articular") imprints were not equidistant from the ground projection of the body's centre of gravity. In a static baropodometric test with shoes and with external orthesis, the loads were unifo…
Personal Reasons for Withdrawal from Team Sports and the Influence of Significant others among Youth Athletes
2013
The aim of this study was to identify the main reasons for withdrawal from team sports and to examine the influence of significant others (i.e., coaches, parents, peers, and siblings) in the decision making concerning withdrawal from youth sports. An attempt was also made to compare withdrawal components and the influence of significant others in terms of gender, level of competition and years of involvement in youth sports. The participants in this study were young football (American soccer) (n=397), ice hockey (n=88) and basketball (n=50) players who had terminated their participation in their sports. Principal component analysis was used to reduce the number of withdrawal items and iden…
Life Cycle Assessment for Supporting Eco-Design: The Case Study of Sodium–Nickel Chloride Cells
2021
The European Union is moving towards a sustainable, decarbonized, and circular economy. It has identified seven key value chains in which to intervene, with the battery and vehicle value chain being one of them. Thus, actions and strategies for the sustainability of batteries need to be developed. Since Life Cycle Assessment (LCA) is a strategic tool for evaluating environmental sustainability, this paper investigates its application to two configurations of a sodium–nickel chloride cell (planar and tubular), focusing on the active material and the anode, with the purpose of identifying the configuration characterized by the lowest environmental impacts. The results, based on a “from cradle…
Influence of a thin horizontal weak layer on the mechanical behaviour of shallow foundations resting on sand
2021
The presence of minor details of the ground, including soil or rock masses, occurs more frequently than what is normally believed. Thin weak layers, shear bands, and slickensided surfaces can substantially affect the behaviour of foundations, as well as that of other geostructures. In fact, they can affect the failure mechanisms, the ultimate bearing capacity of footings, and the safety factor of the geotechnical system. In this research, numerically conducted through Finite Element Code Plaxis 2D, the influence of a horizontal thin weak layer on the mechanical behaviour of shallow footings was evaluated. The obtained results prove that the weak layer strongly influences both the failure me…
A sustainable on-line CapLC method for quantifying antifouling agents like irgarol-1051 and diuron in water samples: Estimation of the carbon footpri…
2016
In this work, in-tube solid phase microextraction (in-tube SPME) coupled to capillary LC (CapLC) with diode array detection has been reported, for on-line extraction and enrichment of booster biocides (irgarol-1051 and diuron) included in Water Frame Directive 2013/39/UE (WFD). The analytical performance has been successfully demonstrated. Furthermore, in the present work, the environmental friendliness of the procedure has been quantified by means of the implementation of the carbon footprint calculation of the analytical procedure and the comparison with other methodologies previously reported. Under the optimum conditions, the method presents good linearity over the range assayed, 0.05-1…
Oleanonic acid, a 3-oxotriterpene from Pistacia, inhibits leukotriene synthesis and has anti-inflammatory activity.
2001
One of the best known bioactive triterpenoids is oleanolic acid, a widespread 3-hydroxy-17-carboxy oleanane-type compound. In order to determine whether further oxidation of carbon 3 affects anti-inflammatory activity in mice, different tests were carried out on oleanolic acid and its 3-oxo-analogue oleanonic acid, which was obtained from Pistacia terebinthus galls. The last one showed activity on the ear oedema induced by 12-deoxyphorbol-13-phenylacetate (DPP), the dermatitis induced by multiple applications of 12-O-tetradecanoyl-13-acetate (TPA) and the paw oedemas induced by bradykinin and phospholipase A2. The production of leukotriene B4 from rat peritoneal leukocytes was reduced by ol…
