ABSTRACT. The purpose of this study is to evaluate anthropometric parameters resul# ng from measurements by their sta# s# cal and mathema# cal processing. The study was conducted on a sample of 300 male subjects from three geographic regions of Romania: South (100 subjects), East (100 subjects) and Centre and West (100 subjects). The anthropometric data collected by 3D scanning of the le& and right foot were grouped into four samples (South, East, Centre-West and Total) and the sta# s# cal indicators of characteriza# on (arithme# c mean and standard devia# on) and sta# s# cal variables (the minimum and maximum values, the amplitude and the coeffi cient of varia# on) were calcuated for each varia# onal sequence of the 20 anthropometric parameters studied. To verify the working hypothesis that there were no signifi cant diff erences between le& and right foot, Student's t-test and the Fisher (F) test were used to verify the variants. Both tests have shown that there are no signifi cant diff erences between the le& foot and the right foot for most anthropometric parameters. Samples for the four groups studied were based on the average of anthropometric parameters of the right and le& foot. One-dimensional normal-size distribu# on for Foot Length (Lp) and Toe Girth (Pd) anthropometric parameters was verifi ed. In this respect, the limits of the frequency classes, the centre of the class and the rela# ve and absolute frequencies were established. This distribu# on is found in the commissioning of the shoe size series. For an op# mal fi t of the shoe, it is necessary to divide the size series into length and width classes.

Manufacturing high quality footwear with an optimal degree of comfort, adapted to the needs of various pathologies of the consumer, with effects on the size and shape of the foot, is conditioned by mastering techniques of processing anthropometric data obtained by 3D foot scanning, transposition of the anatomical, morphological, and biomechanical information into parameters for the design and modeling of shoe lasts and models. Anthropometric measurements are also required because of the specificity of each population, either in terms of length, width, height and foot conformation and consequently, the correlation between them, or growth rate during certain periods of time, depending on socio-cultural conditions, climate, food, etc. The current technological progress makes it possible to obtain 3D anthropometric data and use them in many industrial and research applications. Setting up a database of anthropometric data for the citizens of a country becomes a necessity. Digitized anthropometric data management enables their application in various professional disciplines such as medical studies, anthropometry studies, CAD/CAM footwear design, design of medical devices. This study aims to demonstrate the necessity and importance of creating a database of anthropometric parameters for the Romanian population.

This paper presents the development of a system for measuring the walking speed on a force plate that measures ground reaction. The walking speed measurement system must meet the following criteria: minimal impact on the force plate, easy installation/dismantling, speed must be detected "without contact" and speed of subject must be detected irrespective of the subject's clothing colour, it must provide the possibility of using several types of force plate, it must allow the addition of new functions and have a competitive price. Ground reaction force was measured using the AMTI's AccuGait force plate and the NetForce component, while analysis was performed using the BioAnalysis module. To assess the three components of the ground reaction force provided by the force plate, for a subject not wearing shoes, walking at different speeds, two measurement sessions were organized: placing optical barriers of the walking speed measurement system at distances of 2.5 m and 0.7 m, respectively. Upon analyzing the values ? ? obtained in this case study, we can observe an increase in values of the following components: vertical component, Fz, medio-lateral component, Fy and anterior-posterior component, Fx at the speed of 2.33 m/s, compared to those obtained at 0.6 m/s. By comparing values provided by the force plate with optical barriers of the walking speed measurement system placed at distances of 2.5 m and 0.7 m, respectively, very small differences can be noticed. Therefore, the position of optical barriers does not affect the measurement of ground reaction force components. KEY WORDS: speed, walking, ground reaction force SISTEM DE MÃSURARE A VITEZEI DE DEPLASARE A SUBIECTULUI UMAN LA MERSUL PE O PLATFORMÃ DE FORÞÃREZUMAT. În cadrul acestei lucrãri se prezintã realizarea unui sistem de mãsurare a vitezei de deplasare deasupra unei platforme de mãsurare a reacþiunii solului. Sistemul de mãsurare a vitezei de deplasare trebuie sã respecte urmãtoarele criterii: impact minim asupra platformei, permiterea unei montãri/demontãri facile, detecþia vitezei sã se realizeze "fãrã contact" ºi cea a subiectului sã se realizeze indiferent de culoarea îmbrãcãmintei subiectului, sã ofere posibilitatea folosirii la mai multe tipuri de platforme de forþã, sã permitã adãugarea unor noi funcþiuni ºi sã fie la un preþ competitiv. Mãsurarea forþei de reacþiune a solului s-a realizat cu platforma AMTI's AccuGait, folosind componenta NetForce, iar analiza acesteia s-a realizat cu modulul BioAnalysis. Pentru evaluarea celor trei componente ale forþei de reacþiune a solului furnizate de platforma de forþã, în cazul unui subiect ce nu poartã încãlþãminte, mergând cu viteze diferite, au fost organizate douã sesiuni de mãsurare: amplasarea barierelor optice ale sistemului de mãsurare a vitezei de mers la distanþa de 2,5 m, respectiv 0,7 m. Analizând valorile obþinute în acest studiu de caz, se poate observa o creºtere a valorilor componentelor: verticale Fz, medio-laterale Fy ºi a celei antero-posterioare Fx la viteza de 2,33 m/s faþã de cele obþi...

Gait and balance disorders are common in older adults and they are independent predictors for the functional decline resulting in various degrees of disability and loss of independence. Gait disorders have multiple causes, they have a progressive course and may negatively impact the functional performances. Many gait disorders appear in connection with underlying diseases. The incidence of gait deficiencies is greater in older women. Non-neurological causes are more often identified. Painful joint deformities are common causes of gait disturbances in elderly. The study proposes to identify the influence of age on the walking speed and the support phase during walking. The study included 100 female volunteers, aged between 55 and 87. The subjects participated in the measurement of biomechanical parameters using AMTI's AccuGait System, while speed was determined using a speed measurement system placed above the ground reaction force measuring platform. It was found that there are statistically significant differences among the three age groups in terms of walking speed and support phase.

The purpose of this scientific paper is to present aspects related to a pre-project to develop an Original Romanian Standard by establishing anthropometric foot sizes of Romanian male population, specifying the size systems used in the design and development of lasts used to make shoes in the footwear industry. In the anthropometric survey conducted in Romania, the 3D shape of the foot in order to calculate anthropometric parameters was captured using the INFOOT USB system made up of the 3D scanner and the dedicated MEASURE 2.8 software. Anthropometric studies were conducted on a sample of 300 male subjects from three geographic regions of Romania: South (100 subjects), East (100 subjects) and Centre and West (100 subjects), aged between 24 and 72. Subjects with particular anthropometric features, including deformities and structural abnormalities of the foot, were excluded. Sizes obtained by processing are itemised in an individual anthropometric chart. A data base comprising 300 anthropometric charts was compiled. Values of each dimensional parameter were centralized in a table that constitutes a database. Anthropometric data were grouped for each foot size. The interdimensional interval was determined for each anthropometric size, for each size and standardized values were established.
