Efeito das cargas de treinamento sobre parâmetros fisiológicos de futebolistas

The aim of this study was to investigate the effects of three weeks of training with intensity monitored on the aerobic capacity of professional soccer players. Fourteen players, members of a first division Brazilian Championship team in 2010, aged 22.78 +/- 3.06 years were evaluated pre and post three weeks of training. The anaerobic threshold intensity LAn was determined by bi-segmented method, for this four submaximal efforts of 800 meters with intensities 10, 12, 14 and 16 km/h were applied. Thirty three training sessions were quantified in zones according to heart rate related to the LAn (FCLAn): Z1 - 10% below, Z2 - 90-100% and Z3 - above the FCLAn. During training participants remained 31.17 +/- 14.86%, 42.96% and 25.87 +/- 14.90 +/- 16.67% in Z1, Z2, and Z3 respectively. There were no significant differences in the LAn (pre = 13,29 +/- 0,71 km.h(-1); post = 12,85 +/- 0,90 km.h(-1)), perceived exertion (pre = 11,53 +/- 1,45 u.a; post = 11,23 +/- 1,53 u.a) and FCLAn (pre = 166,64 +/- 10,69 bpm; post = 174,50 +/- 10,89 bpm) between conditions before and after training, indicating that three weeks of training are insufficient to generate positive changes in soccer players LAn.

Corpo: forma, movimento e equilíbrio : um olhar interdisciplinar sobre o corpo, a mente e o comportamento humano

For centuries have studied the man in a segmented manner, which today, even with the emergence of new forms of research, holistic, we see that the influence of centuries of construction of scientific knowledge has taken root in such a way that even now with new understandings about matter and its structure pointing to systemic relations, studies are still largely dichotomized by dividing body, mind and environment. This paper is a literature review on several sources of knowledge, seeking an interdisciplinary way in physics, chemistry, biology, psychology and physical education, relate the body, mind and their interactions with the environment, building a more current concept of body. The studies showed that the physical, cognitive, emotional, social and environmental aspects involve an interaction continues between human been with the world, which changes shapes, balances and transactions, and thus human behavior. So when we speak of the body should relate all this that makes us conscious organisms in constant internal and external dynamic with the universe

Mudanças estruturais nas cadeias de valor na indústria do vestuário: um estudo de caso

In the early 1990 Gary Gereffi and Miguel Korzeniewicz published the book Commodity Chains and Global Capitalism. In the two decades prior to the publication, industrialization worldwide, had undergone significant changes, made more segmented and dispersed in certain regions. In the book, the authors produce a new set of categories to analyze the new standards for establishment and operation of global value chains, their organization, the new geography of manufacturing and the role of the countries in this scenario. Today, in the middle of the second decade of this century, world trade has expanded and multiplied continuously throughout this period, encouraged by reducing barriers and national borders promoted by 'peddlers' of this new era. The purpose of this study is to show that retailers are establishing purchasing offices in producing countries - or in nearby regions - to directly hire outsourced production

Aplicação clínica da mola T do grupo B para retração dos dentes anteriores

A TAS (Técnica do Arco Segmentado) representa uma alternativa à mecânica de deslizamento, muitas vezes dificultada pela incerteza da quantidade de força de atrito envolvida em cada sistema de forças utilizado. Nesse contexto, sabe-se que poucos cursos de Ortodontia no Brasil têm ensinado efetivamente a filosofia e o modo de trabalhar com a TAS. Portanto, este trabalho procura elucidar a forma de raciocínio das relaçÕes entre força e momento manipuladas na TAS, bem como mostrar a forma de confecção e utilização de mola "T" do grupo B, onde objetiva-se a movimentação recíproca dos segmentos posterior e anterior e, por fim, apresentar um caso clínico tratado com esse tipo de mecânica.

Necessidade de ancoragem do grupo A e o controle biomecanico da mola T pré-ativada por curvatura para o fechamento de espacos

Contemporary orthodontics has sought, beyond the esthetic, occlusal and functional goals, treatments even faster and with less visits to the orthodontist — especially in patients that require dental extractions in which the generated space becomes a nuisance. The segmented arch technic (SAT), by the use of a "T" loop spring, has provided such results within these requirements. Therefore, this study aimed to appraise and demonstrate the confection, activation and biomechanical control of "T" loop spring, in the group with high anchorage necessity (group A), for retraction of anterior teeth; as well as to present a case report, with high anterior retraction necessity, treated with "T" loop spring.

Otimização do tracionamento de canino impactado pela técnica do arco segmentado: relato de caso clinico

Upper canines impaction are considered the second most frequent and are associated to important esthetics and functional limitations. Among the treatment strategies described in the literature the most commonly used are the extraction of the primary canines and the surgical exposure followed by orthodontic traction, that requires an adequate interdisciplinary approach. The aim of this case report is to draw the attention of the clinician to the possibility of adapting the segmented arch technique to manage a canine impaction clinical case.

Changes in nuclear morphology and chromatin texture of basal keratinocytes in melasma

BackgroundThe pathogenesis of melasma and the role of keratinocytes in disease development and maintenance are not completely understood. Dermal abnormalities, the expression of inflammatory mediators, growth factors, epithelial expression of melanocortin and sexual hormones receptors suggest that not only melanocytes, but entire epidermal melanin unit is involved in melasma physiopathology.ObjectivesTo compare nuclear morphological features and chromatin texture between basal keratinocytes in facial melasma and adjacent normal skin.MethodsWe took facial skin biopsies (2mm melasma and adjacent normal skin) from women processed for haematoxylin and eosin. Thirty non-overlapping basal keratinocyte nuclei were segmented and descriptors of area, highest diameter, perimeter, circularity, pixel intensity, profilometric index (Ra) and fractal dimension were extracted using ImageJ software.ResultsBasal keratinocyte nuclei from facial melasma epidermis displayed larger size, irregular shape, hyperpigmentation and chromatin heterogeneity by fractal dimension than perilesional skin.ConclusionBasal keratinocytes from facial melasma display changes in nuclear form and chromatin texture, suggesting that the phenotype differences between melasma and adjacent facial skin can result from complete epidermal melanin unit alterations, not just hypertrophic melanocytes.

Inflection and stability points of diphasic logistic analysis of growth

Growth functions with inflection points following a diphasic model, can be adjusted by two approaches using segmented regression or the sum of two functions. In both cases, there are two functions, one for each phase, with inflection and stability points. However, when they are summed, the result is a new function and the points of inflection and stability are different from those obtained from using each function individually. A method to determine these points in a diphasic logistics sum of functions is suggested and the results obtained from fitting the models to eucalyptus growth data showed a better fit of the logistic diphasic sum as compared with segmented regression and monophasic logistic models.
