Full textCyclists have always wanted to keep and/or improve their performance. However, comfort is still a determinant factor because of the time spend on the bike. This comfort is especially altered by the coverings and the irregularities of the field generating loads that are often harmful to health. Therefore, the scientific community is interested in the research of a compromise between performance and health. This interest leads it to explore a large amount of tools characterized by the measure of a physical quantity. Among these values, the acceleration appears as a quantity rich in information. It allows to analyse the performance through monitoring of the athlete or the prevention of health disorders by the evaluation and limitation of the harmful effects

Resumo: Duas classes de medicamentos denominadas estimuladores e ativadores da GCs foram desenvolvidas para uso terapêutico em situações patológicas, onde há menor biodisponibilidade NO ou tolerância farmacológica. A principal diferença entre os moduladores da GCs é que os ativadores atuam de maneira mais eficaz mesmo quando a enzima encontra-se no estado oxidado. O presente trabalho foi dividido em duas etapas, a saber: 1) caracterização farmacológica do ativador BAY 60-2770 em corpo cavernoso (CC) de coelho e 2) avaliação do efeito do ativador BAY 60-2770 e estimulador BAY 41-2272 da GCs em CC isolado de ratos espontaneamente hipertensos (SHR) e normotensos (WKY). O BAY 60-2770 promoveu relaxamento concentração dependente em corpo cavernoso de coelho (pEC50: 7,584 ± 0,1923), sendo este efeito potencializado na presença dos inibidores da GCs ODQ (10 µM; pEC50: 8,170 ± 0,1365) e da fosfodiesterase tipo 5 (PDE5), tadalafil (100 ?M; pEC50: 8,381 ± 0,1334). A contração induzida por estimulação elétrica foi reduzida em aproximadamente 50% na presença de BAY 60-2770, sendo este efeito potencializado na presença de ODQ. Em relação ao relaxamento induzido pela estimulação elétrica, o ODQ e BAY 60-2770 aboliu e aumentou, respectivamente o relaxamento. A co-incubação de BAY 60-2770 com ODQ não alterou o relaxamento em comparação com o ODQ sozinho. Curiosamente, quando BAY 60-2770 foi incubado 20 min antes da adição de ODQ, os relaxamentos induzidos por estimulação elétrica foram parcialmente restaurados quando comparado com o ODQ sozinho. Em relação à segunda etapa do trabalho, o relaxamento induzido pelos moduladores da GCs, BAY 60-2770 e BAY 41-2272 não diferiram em CC de ratos SHR comparados ao seu respectivo controle, porém, estes dados não corroboram com a quantificação de GMPc, no qual evidenciamos aumento dos seus níveis em CC de ratos SHR sendo estes níveis ainda maiores quando na presença de ODQ em comparação ao CC de WKY. Observamos também que o relaxamento induzido pela acetilcolina (ACh) encontrou-se reduzido em CC dos animais hipertensos, entretanto, a adição de BAY 60-2770 ou BAY 41-2272 restaurou este relaxamento. Não foi encontrada diferença na expressão das subunidades ?1 e ?1 da GCs em ratos SHR e WKY, porém quando analisamos a expressão da PDE-5, verificamos maior expressão em CC de ratos SHR. O BAY 60-2770 foi capaz de elevar a pressão intracavernosa em CC de ratos normotensos em todas as frequências estudadas, porém esta elevação somente foi significativa na frequência de 16 Hz. Considerando que 1) BAY 60-2770 induziu relaxamento em CC de coelho e de rato hipertenso de maneira mais potente que o estimulador BAY 41-2272, 2) a adição de ODQ potencializou o relaxamento do BAY 60-2770, mas não do BAY 41-2272 em CC de ambas espécies, 3) o aumento dos níveis de GMPc foi maior em CC de ratos SHR após estímulo com BAY 60-2770, mas não com BAY 41-2272 pode-se concluir que em situações patológicas onde há oxidação da GCs e/ou menor biodisponilidade de NO, os ativadores da GCs seriam mais vantajosos que os estimuladores ou inibidores da PDE5 para o tratamento da disfunção erétil
Abstract: Two classes of drugs referred to as stimulators and sGC activators have been developed for therapeutic use in pathological situations where there is less NO bioavailability and pharmacological tolerance. The main difference between the sGC activators modulators is that they act more effectively even when the enzyme is in the oxidized state. This study was divided into two stages: 1) pharmacological characterization of BAY 60-2770 activator in corpus cavernosum (CC) of rabbit and 2) evaluation of the effect of BAY 60-2770 BAY 41-2272 activator and stimulator of GCs isolated from spontaneously hypertensive rats (SHR) and normotensive (WKY). The BAY 60-2770 induced concentration-dependent relaxation in rabbit corpus cavernosum (pEC 50: 7.584 ± 0.1923), and this increased effect in the presence of GCs ODQ inhibitors (10 ?M; pEC 50: 8.170 ± 0.1365) and the phosphodiesterase type 5 (PDE5), tadalafil (100 ?m; pEC50: 8.381 ± 0.1334). The contraction induced by electric stimulation was reduced by approximately 50% in the presence of BAY 60-2770, and this increased effect in the presence of ODQ. In relation to the relaxation induced by electrical stimulation, ODQ and BAY 60-2770 abolished and increased, respectively the relaxation. Co-incubation with BAY 60-2770 with ODQ did not change compared to the relaxation with only ODQ. Curiously, when BAY 60-2770 was incubated 20 minutes before addition of ODQ, the relaxation induced by electric stimulation was partially restored when compared with only ODQ. In the second part, relaxation induced by modulators of GCs, BAY 60-2770 and BAY 41-2272 did not differ in SHR CC compared to their respective control, however, these data do not corroborate the quantification of cGMP, in which we observed an increase in their levels in SHR rats and these levels even higher in the presence of ODQ in comparing the CC of WKY. We also observed a reduction of the relaxation induced by acetylcholine (ACh) in CC of hypertensive animals, however, the addition of BAY 60-2770 or BAY 41-2272 restored this relaxation. There was no difference in the expression of ?1 and ?1 subunits of sGC in SHR and WKY rats, but when we analyzed the expression of PDE-5, we found greater expression in SHR. The BAY 60-2770 was able to raise up the intracavernous pressure in the normotensive rats in all studied frequencies, but this increase was only significant in the frequency of 16 Hz. Considering 1) BAY 60-2770 induced relaxation in rabbit and hypertensive rat so that the most potent stimulator BAY 41-2272, 2) addition of ODQ potentiated relaxation of BAY 60-2770, but not in BAY 41-2272 in CC of both, 3) increased levels cGMP was greater in SHR rats after stimulation with BAY 60-2770, but not in BAY 41-2272 so can be concluded that in pathologic situations where there is oxidation of GCs and / or low bioavailability of NO, would activators of sGC more advantageous than PDE5 inhibitors or stimulators for the treatment of erectile dysfunction

Giangreco, Maidana Alejandro José. "Cyclic abelian varieties over finite fields." Thesis, Aix-Marseille, 2019. http://www.theses.fr/2019AIXM0316.
Full textThe set A(k) of rational points of an abelian variety A defined over a finite field k forms a finite abelian group. This group is suitable for multiple applications, and its structure is very important. Knowing the possible group structures of A(k) and some statistics is then fundamental. In this thesis, we focus our interest in "cyclic varieties", i.e. abelian varieties defined over finite fields with cyclic group of rational points. Isogenies give us a coarser classification than that given by the isomorphism classes of abelian varieties, but they provide a powerful tool in algebraic geometry. Every isogeny class is determined by its Weil polynomial. We give a criterion to characterize "cyclic isogeny classes", i.e. isogeny classes of abelian varieties defined over finite fields containing only cyclic varieties. This criterion is based on the Weil polynomial of the isogeny class.From this, we give bounds on the fractions of cyclic isogeny classes among certain families of isogeny classes parameterized by their Weil polynomials.Also we give the proportion of "local"-cyclic isogeny classes among the isogeny classes defined over the finite field mathbb{F}_q with q elements, when q tends to infinity

Full textManagement of information technology (IT) assets within an enterprise is necessary to control organizational costs and ensure that the necessary business requirements are supported. For over 10 years, the Navy Marine Corps Intranet (NMCI) was charged with this task in Navy and Marine Corps IT systems. With the expiration of the NMCI contract, the Marine Corps is now managing its own IT assets. To understand the scope of IT assets to enable better management, this research explores items accounted for within the master data repository, which is aiding in the migration of legacy logistics systems to GCSS-MC. These items and their associated costs are divided into categories to provide a baseline view of Marine Corps IT hardware assets. An equivalent annual cost is applied to assets to suggest a refreshment cycle for laptops, desktops, and servers. This demonstrates a method that can provide IT managers with a means of determining when an asset should be refreshed.
Forey, Arthur. "Invariants motiviques dans les corps valués." Thesis, Paris 6, 2017. http://www.theses.fr/2017PA066557/document.
Full textThis thesis is devoted to define and study some motivic invariants associated to semialgebraic sets in valued fields. They are boolean combinations of sets defined by valuative inequalities. Our main tool is the theory of motivic integration, which is a kind of measure theory with values in the Grothendieck group of varieties defined over the residue field. In the first part, we define the notion of motivic local density. It is a valuative analog of complex Lelong number, Kurdyka-Raby real density and p-adic density of Cluckers- Comte-Loeser. It is a metric invariant with values in a localization of the Grothendieck group of varieties. Our main result is that it can be computed on the tangent cone with motivic multiplicities. We also establish an analog of the local Cauchy-Crofton formula. We finally show that the density of a germ of plane curve defined over the residue field is equal to the sum of the inverses of the multiplicities of the formal branches of the curve. The goal of the second part is to define a ring morphism from the Grothendieck group of semi-algebraic sets defined over a valued field K to the Grothendieck group of Ayoub’s categoryof rigid analytic motives over K. We show that it extends the morphism sending the class of an algebraic variety to the class of its cohomological motive with compact support. This gives a notion of virtual cohomological motive with compact support for rigid analytic varieties. We also show a duality theorem allowing us to compare the cohomological motive of the analytic Milnor fiber with the motivic Milnor fiber

Resumo: O sildenafil, inibidor específico de PDE5, é utilizado no tratamento da disfunção erétil. Na procura de um inibidor mais potente e seletivo de PDE5, testamos vinte novos análogos do sildenafil (6a-v), caracterizados pela presença de um grupo sulfonil ou de um substituinte n'n'etilendiamina na posição do grupo metil da piperazina. Os objetivos deste trabalho foram: 1) Avaliar a atividade inibitória da PDE5 de plaquetas humanas; 2) Avaliar o efeito relaxante dos análogos do sildenafil em corpo cavernoso de coelho; 3) Avaliar o efeito relaxante dos análogos do sildenafil em anéis de aorta de coelho. Foi utilizado sangue de voluntários sadios para a atividade inibitória da PDE5 e coelhos New Zealand machos (2-3 kg) procedentes do CEMIB-UNICAMP para os estudos funcionais. Os animais foram anestesiados com uretana, o corpo cavernoso e a artéria aorta foram rapidamente removidos. O tecido cavernoso e anéis de aorta foram montados em banho para órgão isolado contendo solução de Krebs (37oC, 95% O2 / 5% CO2). Os tecidos foram ligados a transdutores isométricos conectados a um sistema PowerLab® de aquisição de dados. Nossos resultados mostraram que a atividade inibitória da PDE5 induzida pelos análogos do sildenafil em plaquetas humanas foi de maneira dependente da concentração. Os compostos 6m, 6n e 6q mostraram valores elevados de IC50 para inibir a PDE5 plaquetária, enquanto que os compostos 6a, 6b, 6d, 6g e 6p produziram inibição inferior a 50%. A potência inibitória (IC50) dos compostos 6c, 6e, 6f, 6h, 6i, 6l e 6o foi similar ao sildenafil (IC50: 0,05 µM) com valores variando entre 0,05 e 0,15 µM. Os análogos que derivaram da molécula n'n'etilendiamina (6r, 6s, 6t e 6v) mostraram uma boa atividade inibitória com valores entre 0,20-0,51 µM. Interessantemente, o composto 6u mostrou uma potência de 0,04 µM, o qual representou o menor valor obtido dos análogos do sildenafil. Nos estudos funcionais, todos os análogos do sildenafil, à exceção do análogo 6m, relaxaram preparações de corpo cavernoso de coelho de maneira dependente da concentração. Particularmente, o análogo 6f mostrou o melhor perfil farmacológico no relaxamento, com potência similar ao sildenafil, e pode servir de base para o desenvolvimento de novos inibidores de PDE5 para o tratamento da disfunção erétil. Além disso, nossos resultados mostraram que os análogos do sildenafil produzem relaxamento dependente da concentração em anéis de aorta de coelho com endotélio íntegro ou removido. Somente o análogo 6b e 6m apresentaram valores de potência inferiores quando comparados ao sildenafil em tecidos com endotélio íntegro. A remoção do endotélio ou a adição do LNAME ou do ODQ (inibidor da NO sintase e da guanilil ciclase solúvel, respectivamente) em tecidos com endotélio íntegro, provocou deslocamento à direita para o sildenafil e seus análogos, à exceção do 6r e 6u que não apresentaram diminuição da potência decorrente da inibição do NO, seja pela remoção do endotélio, pela inibição da NO sintase ou pela inibição da guanilil ciclase solúvel. Nossos dados também mostram que o 6r e 6u, em combinação com o BAY 41-2272, aumentam a potência evocada por estes análogos tanto em anéis de aorta com endotélio íntegro ou removido. O relaxamento evocado pelo sildenafil, 6r e 6u não envolve a participação de canais de potássio e de cálcio, nem envolve a formação de prostanóides. As respostas relaxantes destes dois análogos não foram alteradas em tecidos desprovidos de endotélio, mostrando-se independentes da via NO/GMPc. Isto sugere que estes dois análogos podem ser de particular interesse em patologias decorrentes de disfunção endotelial.
Abstract: Sildenafil, a cGMP-specific phosphodiesterase-5 (PDE5) inhibitor, is used for the treatment of erectile dysfunction. In the search for a potent and selective PDE5 inhibitor, new sildenafil analogues (6a-v), characterized by the presence on the sulphonyl group in the 5' position of novel N-4-substituted piperazines or ethylenediamine moiety, were synthesized. The aim of this work was 1) To evaluate the PDE5 inhibitory activity in human platelets; 2) To evaluate the relaxing effect of sildenafil analogues in rabbit corpus cavernosum; 3) To evaluate the relaxing effect of sildenafil analogues in rabbit isolated aorta. Blood from human volunteers were collected and used for PDE5 inhibitory activity and Male New Zealand rabbit (2-3 kg) for functional studies. The rabbits were anaesthetized with urethane and sacrificed. The cavernosal tissue and aortic rings were mounted in organ bath containing Krebs solution (37oC, 95% O2 / 5% CO2). Each tissue was connected to an isometric transducer which was connected to a data acquisition system Powerlab®. Our results showed that sildenafil and its analogues concentration-dependently inhibited PDE5 activity in human platelets. Compounds 6m, 6n and 6q showed higher values of IC50 to inhibit PDE5 of platelets, whereas compounds 6a, 6b, 6d, 6g and 6p did not reach 50% of inhibition. The inhibitory potency of PDE5 for 6c, 6e, 6f, 6h, 6i, 6l and 6o were similar with sildenafil (IC50: 0,05 µM) with values between 0,05-0,15 µM. Derived analogues from n'n' substitution showed great PDE5 inhibitory activity. Interesting, compound 6u exhibited greater IC50 value (0,04 µM). In functional studies, all sildenafil analogues with exception of 6m, relaxed concentration-dependently rabbit corpus cavernosum. Compound 6f exhibited great pEC50 value in corpus cavernosum and could be used as base for developing new PDE5 inhibitors. Moreover, our results showed that sildenafil analogues concentration-dependently relaxed both endothelium-intact and - denuded aortic rings with similar potency values of sildenafil. Compounds 6b and 6m showed lower values of potency when compared to sildenafil in endothelium intact. Endothelium denudation or addition of L-NAME or ODQ (NOS and sGC inhibitors, respectively) caused marked rightward shifts in the curve to sildenafil and its analogues, whereas the relaxation curves for 6r and 6u were not altered after endothelium removal or either by the NO synthase or sGC inhibition. Moreover, our data also suggest that compound 6r and 6u increased the potency values in combination with BAY 41-2272 in both intact and denuded endothelium. The relaxation evoked by sildenafil, 6r and 6u does not involve either calcium or potassium channels or prostanoids formation. The relaxing responses by these compounds were independent of NO/cGMP pathway, suggesting that these compounds may be used in several diseases involving endothelium dysfunction.

In the second part we tackle the problem of rationality and independence of l. More precisely, we introduce a notion of compatibility for systems of l-adic complexes and establish its stability by the above operations, in a slightly more general context (equivariant under finite groups).

Full textTurbidite systems are huge submarine sedimentary fans located off rivers, at the foot of the continental slope. They constitute the most distal terrigeneous deposits of a fluvial system. Their internal structure, defined as a stacking of channel-levee systems, show architectural changes through time. Forcing factors of these architectural changesare still poorly understood, and the respective role of internal (related to the own functioning of the system) or external forcing factors (climate, seal-level variations, tectonics) remains debated. To better understand the role of these controlling factors, a detailed study of the Congo system architecture was carried out. This study was conducted as part of the Reprezaï research project (Ifremer/IUEM, since 2006), following the Guiness and ZaïAngo projects (Ifremer/Total, 1992-2003), during which many oceanographic surveys allowed acquiring an important geophysical and geological data base. A quantitative analysis of different architectural parameters from the channels (e.g. total length, length built after avulsion,…) of the Congo Axial Fan (last 200 ka) reveals progradational-retrogradational sedimentary cycles of the depocenters, the highest retrogradations corresponding to avulsions located very upfan. Depocenters identified at the termination of the channels correspond to relatively elongated lobe complexes (according to the nomenclature of Prélat et al., 2009) with greatly variable volumes (from 3 to 196 km3) both in time and space, without any cyclicity like that identified by other parameters. The cumulative volume of these lobe complexes represents up to 31% of the Axial Fan volume. The multiproxies study (14C dating, δ18O, XRF measurements, Total Organic Carbon…) of cores sampled on the most prograding and retrograding channels provided a chronological framework to these sedimentary cycles. The temporal evolution of the architectural parameters was compared with changes in paleoenvironmental and paleoclimatic signals (pollens, TOC, XRF and MSCL measurements, clay mineralogy,…) recorded in the sediments of a reference core deposited simultaneously to the Axial Fan, but located outside the turbidite flows. Results highlight a strong link between the architectural evolution of the turbidite system and the Congo River discharge. These, as well as the expansion of the vegetation cover in the catchment area, control the sand/clay ratio and thus, at least partly, the transport capacity of turbidity currents that build the channel-levee systems. Both factors depend on rainfall related to the monsoon intensity variations in relation with precession (19-23 ka Milankovitch). A scenario for the deposition of channel-levee systems and lobes of the Axial Fan in link with arid/humid climate variations in the catchment area has been proposed thanks to good stratigraphic constraints for the last 40 ka. During arid periods, turbidity currents are infrequent and present a high sand/clay ratio which decreases their transport capacity. These turbidity currents are suitable to channel aggradation, generating favorable conditions for the subsequent creation of upfan avulsion. During periods of transition of arid to humid conditions, when the canopy is still underdeveloped, fluvial discharge and significant sediment load increases result in an increase of the turbidity currents volume, which favors upfan avulsions. Finally, during humid periods, Congo discharge is characterized by a strong liquid flow and a mainly clayey solid discharge which decreases gradually as the canopy extends. These conditions generate turbidity currents with decreasing transport capacity through time. However the transport capacity of these currents remains sufficient to reach distal portions of the systems and favor channels progradation. This climatic factor seems therefore to regularly disrupt the more perennial internal control which is also highlighted by the Congo Axial Fan architecture

Full textFrom "Six Moral Tales" to "Comedies and Proverbs", from "Comedies and Proverbs" to "Tales of the Four Seasons" Eric Rohmer develops a work that is organized in cycles whose center, always reactivated from film to film, is constituted by the question of desire, its excesses and its shortcomings. How can this cinema, marked by an aesthetic favoring the natural, embrace theatricality ? Theatricality precisely whose appearance and modalities will determine our study of the Rohmerian work, whose formal coherence is based on the principles of a cinema vérité initiated in the mid-1900s by the authors of the New Wave, that we will mainly examine, so as to identify the conditions, forms and the effects of an aesthetic favoring, from film to film, a dramaturgy of speech and gaze. From this perspective, we will study the staging of speech and the body in their relationship with places, considering the way in which this cinema constructs its characters through a theater of being and enhances them through the image. By framing that favors the capture of the body and its emotions, articulating plot in stages marked by a strong dramaticity, this cinema finally applies an aesthetics of fascination which is, ultimately, only the reflection, constantly thematized in the film, of an identification by the filmmaker of cinema as an ever renewed quest for the beauty of the world. The dramaturgical use the mechanism of chance, an equivalent principle, on the level of plot, of the deus ex machina, will make it possible, if necessary, to transform the character's deceptive quest into the joy of discovering that the Other was the man or woman we expected. And if, in such a narrative framework, there is a risk of excessive sentimentality, the works escapes it by the dynamis conferred by theatricality, playing with all the mechanisms of surprise, with the variation of registers and tones, finally introducing a certain irony into the discrepancy between what is shown – the image – and what is said – the discourse

Full textNem sempre é comum associar a prática de desporto à engenharia e tão pouco é viável comparar o corpo humano a qualquer engenho do tipo mecânico. No entanto, desporto e engenharia convergem num novo domínio de investigação - a engenharia no desporto. Estudos revelam a importância de trabalhar e exercitar o corpo humano com fins terapêuticos no que diz respeito à prevenção de lesões futuras, admitindo-se que o decréscimo da sedentariedade no quotidiano de um ser humano promove o aumento da esperança média de vida. Mas, será que os referidos ganhos são tão lineares quanto parecem? A verdade, nua e crua, reside no facto de toda e qualquer atividade, quando levada ao limite, ter os seus efeitos nefastos. Assim, associado à prática de qualquer desporto existe sempre um risco de ocorrência de lesões futuras, tipicamente relacionadas com as vibrações induzidas. Deste modo, eleva-se cada vez mais a necessidade de estabelecer uma norma internacional que sirva de padrão para o estudo do corpo humano como um todo, ao invés de o tratar como um produto de engenharia. Na presente dissertação é apresentada uma avaliação biomecânica que pretende desmistificar o efeito das vibrações, nos sistemas mão-braço e corpo inteiro, na prática de um desporto centenário como é o caso do ciclismo sendo que se estende a análise aos domínios do ciclismo de estrada (com segmentos de BTT), ciclismo de pista e ao treino de um atleta em rolos. O estudo compreende a utilização das normas internacionais ISO 5349 e ISO 2631, associadas ao estudo da vibração mão-braço (VMB) e da vibração corpo inteiro (VCI) respetivamente, sendo que os valores obtidos são comparados com dados de referência internacional, indicados pela diretiva nº2002/44/CE, atualmente em vigor no território nacional. O método experimental adotado consistiu na instrumentação da bicicleta, com a colocação de um acelerómetro no guiador para avaliação do sistema mão-braço e posteriormente no selim para aquisição de valores de aceleração de forma a avaliar o efeito das vibrações no corpo inteiro. Os principais resultados e conclusões deste trabalho indicam que, facilmente são ultrapassados os valores diários recomendados de exposição à vibração de tal modo que, a ocorrência de impactos e vibrações transientes conduz a uma elevada solicitação musculosquelética do praticante de ciclismo, nomeadamente ao nível de ombros, braços, punhos, joelhos, e coluna vertebral. Contudo, a exposição de um atleta, num dado desporto, a estas condições não é diária, devendo ser considerado um fator de recuperação, inerente ao período em que este não é exposto. No entanto a literatura científica não reúne dados suficientes para tratar essa ponderação de forma exímia pelo que não se considera esse parâmetro no presente estudo.
It is not usually common to associate sports to engineering. In fact, it is not even feasible to compare the human body to any sort of mechanical device. However, sport and engineering have been converging in a brand new researching area – sports engineering. Studies report the importance of working and exercising the human body for therapeutic purposes, in order to prevent future injuries assuming that active people are estimated to have a greater life expectancy. But, are these sort of gains as linear as they seem to be? The truth, in an unvarnished way, is that any kind of activity, when pushed to the very limit, has their adverse effects. Thus, practicing a sport implies a sustained risk of developing injuries due to induced vibrations which increases the need to create an international regulation to serve as standard for the study of human body as a whole, rather than treating it as a product of engineering. This work presents a biomechanical assessment that aims at demystifying the effect of vibrations for both the arm-hand and whole body systems, considering the practice of a centenary sport such as cycling. The study comprehends an analysis on road cycling domains (with segments of mountain biking), track cycling and the exercise of an athlete in rollers, requiring the use of international regulamentation ISO 5349 and ISO 2631, related to the study of arm-hand vibration and whole body vibration respectively, and the values obtained are compared with referred data, indicated by the directive nº2002/44/CE, currently in force in the country. The adopted experimental method consists in instrumenting a bicycle with the allocation of tri-axial accelerometer on the handlebar to acquire data on the harm-and system and subsequently introduced in the seat post to quantify the effect of the induced vibrations imposed to the whole body system. The results indicate that the recommended daily dose of exposure to vibrations is highly exceeded, which means that impacts and transient vibrations lead to a higher musculoskeletal request particularly in what concerns shoulders , arms, wrists, knees and spine. However, it is common that a certain athlete in a given sport does not exercise in a daily basis meaning that it should be imposed a recovery factor relative to the period the athlete is not exposed. On the other hand, lectures do not gather enough data to address this weighting factor and the current study will do the same.
