Abstract
The aim of this study was to assess the effect of core strength training performed on a stable surface (CTS) compared with core strength training performed on an unstable surface (CTU) on physical fitness (jump performance, sprint, and repeated sprint ability (RSA)) and quality of movement (Fundamental Movement Screen) in professional female futsal players. Fourteen professional female futsal players (mean age: 23.7 ± 5.1 years, age range: 18-28 years) were randomly assigned to a CTS (n = 7) or a CTU (n = 7) group. The intervention program was carried out 3 times a week over 6 weeks. Players of both groups performed the same four core-strengthening exercises. The only difference between the two interventions was that the CTU group performed all exercises (i.e., shoulder bridge, side bridge, prone plank, and crunch) on an unstable surface (Togu® Dyn-Air). Within-group analysis showed significant improvements (p < 0.001) in 10 m sprint performance from the pre- to post-test in the CTS (+4.37%) and CTU (+5.00%) groups. Players in both the CTS (+10.39%) and CTU (+11.10%) group also showed significant enhancement in the Functional Movement Screen total score, from the pre-test to post-test. In addition, a significant time effect was also observed for the CTU group in the relative score of the RSA test decreasing from the pre- to post-test (-30.85%). In the between-groups analysis, there were no significant differences between the core strength training groups (CTS vs CTU) in any variable. To conclude, sprint and Functional Movement Screen performance improved following CTS and CTU when conducted in combination with regular futsal training. In addition, CTU had limited benefit in RSA compared to CTS.

Published: January 2019

Abstract
The current study aimed to examine the effect of verbal instruction on explosive force production and between-session measurement reliability during maximal voluntary contractions of knee extensors. Following familiarization, 20 healthy males performed 3 maximal contractions with a “hard-and-fast” instruction and 3 maximal contractions with a “fast” instruction during 2 test-retest sessions. Knee extension maximal voluntary force (Fmax) and the maximal rate of force development (RFDmax) were measured. Maximal electromechanical delay (EMDmax), and the maximal rate of muscle activation (RMAmax) of quadriceps muscles were determined. No significant effect of instruction was observed on Fmax (p > 0.05). The RFDmax and RMAmax were significantly higher with the “fast” compared to the “hard-and-fast” instruction (36.07%, ES = 1.99 and 37.24%, ES = 0.92, respectively), whereas EMDmax was significantly lower with the “fast” instruction compared to the “hard-and-fast” instruction (-3.79%, ES = - 0.29). No significant differences between test and retest measurements were found (p < 0.05). However, the reliability of the RFDmax was higher with the fast instruction compared to the hard-and-fast instruction (CV: 7.3 vs. 16.2%; ICC: 0.84 vs. 0.56). Besides, the RFDmax was associated with the RMAmax and EMDmax with a significant effect of instruction. Data showed that the instruction given prior contracting muscle affected explosive force production and associated neuromuscular variables. As a result, the “fast” instruction may be preferred in the assessment of explosive force capacity of skeletal muscle during maximal efforts.
Maximizing the Functional Performance Outcomes of Patients Undergoing Rehabilitation by Maximizing their Overall Health and Wellbeing
Authors: Dean Elizabeth 
Published: January 2019

Abstract
To maximize the performance of an athlete, a team of experts work together to ensure each athlete achieves the maximal benefit from their prescribed exercise conditioning programs. In addition to the exercise specialists, the athlete’s team frequently includes psychologists (who address performance anxiety, stress, and depression), counselors (who address smoking cessation, reduction or elimination of alcohol consumption if necessary, weight optimization, and optimal sleep), and nutritionists (who address optimal nutrition and body mass attributes). Such a collaborative approach has become standard practice for athletes aiming to excel in their sports. Despite unequivocal and compelling evidence, this paradigm has only weakly been transferred to the needs of patients participating in rehabilitation programs. These individuals, like the athlete, also need to achieve their highest level of functional performance and recovery for carrying out their activities of daily living, managing the needs of their families, and often returning to work. This article reviews the evidence-based literature and the implications of this multifaceted approach in rehabilitation programs. The augmented benefits to exercise training and conditioning (prescriptive activity/exercise and less sitting) along with their ‘effect sizes’ are described in the rehabilitation context, in conjunction with smoking cessation, reduced harmful alcohol consumption, optimal nutrition, optimal body mass, manageable stress, and optimal sleep. These factors can be viewed as physical performance enhancers both in individuals participating in rehabilitation whose aim is maximal performance and recovery and in athletes aiming for maximal performance in their sports. Thus, without targeted attention to these lifestyle factors, rehabilitation outcomes cannot be maximized. The evidence presented in this article has implications for health professionals including physical therapists and others who are practicing in rehabilitation settings and those working with individuals in need in the community.

Published: January 2019

Abstract
The aim of this study was to analyze the effect of different pitch surfaces (artificial turf, natural turf and dirt field) on positioning and displacement of young soccer players (age: 13.4 ± 0.5 yrs; body height: 161.82 ± 7.52 cm; body mass: 50.79 ± 7.22 kg and playing experience: 3.5 ± 1.4 yrs). Data were collected using GPS units which allowed to calculate spatial distribution variability, assessed by measuring entropy of individual distribution maps (ShannEn). Ellipsoidal areas (m2) representing players’ displacement on the pitch, centred on the average players’ positional coordinates, were also calculated, with axes corresponding to the standard deviations of the displacement in the longitudinal and lateral directions. Analysis of variance (ANOVA) was used to evaluate differences between pitch surfaces and across players’ positions. There was significant effect in positioning (η2 = 0.146; p < 0.001) and displacement (η2 = 0.063; p < 0.05) by the players between pitch surfaces. A dirt field condition induced an increase in the players’ movement variability, while players’ displacement was more restricted when playing on artificial turf. Also, there were significant effects on positioning (η2 = 0.496; p < 0.001) and displacement (η2 = 0.339; p < 0.001) across players’ positions. Central midfielders presented the greatest movement variability and displacement while fullbacks showed the lowest variability. Subsequently, the results may contribute to implement strategies that optimise players’ performance in different surface conditions.

Apresentação. A emergência da imagem crítica
Authors: Costa Luiz Cláudio da 
Published: January 2019

O enunciado central – a emergência da imagem – desvela algo da discussão que propomos para este dossiê: aparição que se eleva como sintoma; visibilidade que se manifesta com urgência. Situando nosso interesse primeiro pela imagem no âmbito artístico, pretendemos interrogar sobre sua potência, sua sacralidade, sua tipologia, seu poder manipulador, seus ritmos, sua pedagogia, sua história, seu poder de figurar. Nossa época necessita de uma abordagem crítica e transdisciplinar da imagem, visto que sua relevância ultrapassa as artes, afetando igualmente a antropologia, a história da arte, a cultura visual, a sociologia, a religião. A imagem povoa o cotidiano das pessoas. O destino das imagens parece estar sob a luz dos holofotes no século XXI, não somente pelo fator tecnológico, mas também pela inserção e influência das imagens em diversas zonas de interesse, de práticas e saberes. Acreditamos que as imagens ainda estão à espera de suportes, à espera de que possamos as qualificar (qualificá-las?), demonstrar suas possibilidades e contradições. Convivemos com muitas imagens, mas ainda nos faltam aquelas cuja intensidade dialética permitiriam fomentar novas densidades para o pensamento visual e a construção de uma visibilidade crítica que possa contribuir com os ritmos da percepção no novo milênio.

Sobre as Limitações do Dilema do Bonde para a Avaliação dos Riscos Impostos por Veículos Autônomos
Authors: Kinouchi Renato Rodrigues 
Published: January 2019

Neste trabalho discuto a adequação da versão original do dilema do bonde no que concerne a questão dos potenciais acidentes com veículos autônomos. A principal crítica se refere à impossibilidade de incluir questões relativas aos riscos e incertezas envolvidos em tais acidentes. A seguir, apresento um modelo abstrato que satisfaz os requisitos conceituais da noção padrão de risco, o qual assumirá a forma de um dilema do bonde de natureza probabilística. Mediante a análise de dois exemplos, procuro mostrar que o novo modelo é mais adequado para se avaliar a questão dos riscos impostos por veículos autônomos. Embora não pretenda dar uma solução para o problema colocado, procuro esclarecer como tais veículos pode impor riscos distintos a pedestres e passageiros, uma questão ética não contemplada na versão original do dilema.

Published: January 2019

Мета. Проаналізувати результати застосування модифікованої методики корекційної остеотомії бічної кісточки гомілки при її хибно консолідованих переломах без виражених деструктивно-дистрофічних змін травмованого гомілковостопного суглоба.
Матеріали і методи. Дослідження проведено щодо 37 пацієнтів, з них чоловіків - 16, жінок - 21, середній вік яких становив (38 ± 7) років. З моменту травми минуло від 6 до 15 міс, у середньому - (7,8 ± 1,9) міс. Під час рентгенологічного обстеження у пацієнтів виявлено післятравматичний остеоартроз гомілковостопного суглоба І-ІІ стадії за Келгреном - Лоуренсом.
Корекційна остеотомія включала поперечну остеотомію бічної кісточки гомілки на рівні суглобової щілини гомілковостопного суглоба, що уможливило виконати трьохплощинну корекцію положення кісточки та відновити співвідношення в гомілковостопному суглобі.
Функціональні результати оцінювали за шкалою AOFAS (American Orthopaedic Foot and Ankle Society Score) для гомілковостопного суглоба та заднього відділу стопи до та після хірургічного лікування. Ступінь прогресування остеоартрозу визначали за результатами рентгенографії в навантаженні згідно з класифікацією Келгрена - Лоуренса. Середній термін спостереження з аналізом результатів становив (1,9 ± 0,6) року.
Результати. Оцінка функціональних результатів за шкалою AOFAS у межах терміну спостереження зросла з (58,7 ± 2,4) до (86,2 ± 1,8) бала. Під час рентгенологічного обстеження у всіх пацієнтів спостерігали відновлення осі гомілковостопного суглоба, але у 8 (21%) пацієнтів виявили ІІІ стадію остеоартрозу, що свідчило про його прогресування.
Висновки. Модифікована методика корекційної остеотомії бічної кісточки гомілки при її хибно консолідованих переломах дає змогу відновити конгруентність та біомеханічну вісь подкодженого суглоба, значно покращити його функціональну здатність та уповільнити прогресування післятравматичного остеоартрозу.

O objetivo do presente trabalho é verificar o potencial de atributos polarimétricos extraídos de imagens-radar PALSAR/ALOS conjugados ao atributo de coerência interferométrica dos dados TanDEM-X/TerraSAR-X para o mapeamento de uso e cobertura da terra na Amazônia brasileira. Na análise dessas imagens-radar uma série de atributos polarimétricos foi extraída a partir da informação de fase utilizando teoremas de decomposições de alvos formulados por Cloude-Pottier, Touzi, Freeman-Durden e Yamaguchi. Esse procedimento resultou em quatro grupos de atributos, os quais foram classificados individualmente e/ou associados à coerência interferométrica, através do algoritmo MAXVER-ICM. Empregando informações de campo, a validação temática foi realizada por matrizes de confusão, índice Kappa e exatidão global. No cenário investigado nove classes temáticas (floresta primária; solo em pousio ou solo preparado; sucessões secundárias avançada, intermediária e inicial; área cultivada; pasto sujo; pasto limpo; e corpo d’água) foram identificadas no processo de mapeamento deste ambiente tropical. Atributos polarimétricos derivados do teorema de decomposição de Cloude-Pottier (H/α/A) associados ao atributo de coerência interferométrica (γ) mostraram melhor desempenho classificatório (Kappa = 0,72 e exatidão global = 78,79%) comparado aos demais. A B S T R A C TThe aim of this study is to verify the potential of polarimetric attributes extracted from PALSAR/ALOS-1 radar images combined to the interferometric coherence from TanDEM-X/TerraSAR-X data for land use and land cover mapping in the Brazilian Amazon. From the phase informationIn of these radar images, polarimetric attributes were extracted by target decomposition theorems formulated by Cloude-Pottier, Touzi, Freeman-Durden and Yamaguchi. This procedure resulted in four groups of attributes, which were classified individually and/or associated with interferometric coherence descriptors through the MAXVER-ICM algorithm. Using field information the method was validated based on the confusion matrix, Kappa and overall accuracy. A total of nine thematic classes were identified in the mapping process of this tropical environment: primary forest; advanced, intermediate and initial secondary succession; bare soil; agricultural area; two classes of pasture and water body. Derived attributes from Cloude-Pottier decomposition theorem (H/α/A) associated with interferometric coherence attribute (γ) showed the best classification performance (Kappa = 0.72 and an overall accuracy = 78.79%) compared to the other methods.Keywords: land use and land cover; Amazon.
