The purpose of this study was to determine the physiological, anthropometric, performance, and nutritional characteristics of the Brazil Canoe Polo National Team. Ten male canoe polo athletes (age 26.7 ± 4.1 years) performed a battery of tests including assessments of anthropometric parameters, upper-body anaerobic power (Wingate), muscular strength, aerobic power, and nutritional profile. In addition, we characterized heart rate and plasma lactate responses and the temporal pattern of the effort/recovery during a simulated canoe polo match. The main results are as follows: body fat, 12.3 ± 4.0%; upper-body peak and mean power, 6.8 ± 0.5 and 4.7 ± 0.4 W · kg(-1), respectively; 1-RM bench press, 99.1 ± 11.7 kg; peak oxygen uptake, 44.3 ± 5.8 mL · kg(-1) · min(-1); total energy intake, 42.8 ± 8.6 kcal · kg(-1); protein, carbohydrate, and fat intakes, 1.9 ± 0.1, 5.0 ± 1.5, and 1.7 ± 0.4 g · kg(-1), respectively; mean heart rate, 146 ± 11 beats · min(-1); plasma lactate, 5.7 ± 3.8 mmol · L(-1) at half-time and 4.6 ± 2.2 mmol · L(-1) at the end of the match; effort time (relative to total match time), 93.1 ± 3.0%; number of sprints, 9.6 ± 4.4. The results of this study will assist coaches, trainers, and nutritionists in developing more adequate training programmes and dietary interventions for canoe polo athletes. 相似文献

‘Language death’ is an undeniable phenomenon of our modern times as languages have started to disappear at an alarming rate. This has led linguists, anthropologists, philosophers and educationists to engage with this issue at various levels in an attempt to try to understand the decline in this rich area of human communication and culture. In this article I refer to some interesting and innovative educational projects in the Amazon region of Brazil, which are revitalizing local languages, cultures and communities. I analyse these projects in the light of some of Paulo Freire’s ideas, particularly his views on conscientization, praxis and contextualization, and will argue that these educational ventures might be viewed as useful templates for other countries and peoples seeking to reverse or avoid ‘language-culture’ death. 相似文献

ABSTRACTThe aim of this study was to examine the relationship between the peak velocity derived from the Carminatti Test (T-CAR) (PVT-CAR) and physical match performance in young soccer players. Thirty-three youth soccer players were recruited from 2 non-professional clubs. Friendly matches and small-sided game were performed. Physical match demands were assessed using Global Positioning System (GPS) technology. On a separate occasion, the players were submitted to the T-CAR. Players were categorised into 3 groups based on their T-CAR performance: Low (PVT-CAR ≤ P33), Intermediate (P33 > PVT-CAR < P66) and High (PVT-CAR ≥ P66). The PVT-CAR (15.5 ± 0.7 km·h?1) was significantly related to high-intensity activities (HIA; r = 0.78, P < 0.001), high-intensity running (HIR; r = 0.66, P < 0.001), sprinting (r = 0.62, P < 0.001) and total distance (TD) covered (r = 0.47, P < 0.01) during friendly matches. The PVT-CAR was strongly correlated with the amount of HIA (r = 0.81, P < 0.001), HIR (r = 0.85, P < 0.001) and TD covered (r = 0.81, P < 0.001) during small-sided game. No significant correlation was observed between the PVT-CAR and distance of sprinting (r = 0.49, P = 0.067) during small-side game. Furthermore, players in the High group covered significantly more TD (10%) and did more HIA (42%), sprinting (31%) and HIR (25%) during friendly matches compared to the players classified as having Low performance on the T-CAR. These differences still remained after adjusting for chronological age (CA), maturity and body size. In conclusion, the current study gives empirical support to the ecological and construct validity of this novel field test (T-CAR) as an indicator of match-related physical performance in young soccer players during pubertal years. 相似文献

This paper analyses teaching and non-teaching staff perceptions on the implementation of internal quality assurance (QA) practices at their higher education institutions. The aim is to understand how far different perspectives on quality – as culture, as compliance or as consistency – are reflected in the views of these two groups on such practices. Data from a survey sent to all Portuguese institutions show that, to some extent, the perspectives of quality as culture and quality as compliance seem to permeate both groups’ views. This is evident in regard to the factors identified as supporting the development of internal QA, the main features underlying the implementation of such practices and their main effects. As the study allows for a better understanding on how these practices are perceived by teaching and non-teaching staff, it can contribute to promoting the critical reflection of institutions about QA and the way it can be both more effective and aligned with academia’s needs and expectations, contributing to influencing institutional practices. 相似文献

This article claims that Freire’s work offers an important ground for a potential theory of intercultural ethics and, for that purpose, examines his ideas at different levels: (1) the ontological; (2) the ideological; (3) the political; (4) languages and languaging; and (5) cultural identity and diversity. Freire never used the word ‘intercultural’, although it is suggested here that this is due to the fact that terminology related to cultural diversity has changed over time and in his day this term was not yet common currency. Moreover, Freire uses more often the term ‘multiculturalidade’ rather than ‘multiculturalismo’ (multiculturalism) since the former suffix ‘-dad(e)’ has a different meaning which refers to the ontological nature of the condition and is more usual in both Portuguese and Spanish. This article also argues for the relevance of a theory of intercultural ethics in the contemporary world that imprints (inter)cultural flexibility on the current hermeneutics of ethics while preventing excessive abuses on behalf of relativism, dogmatism, essentialism and fundamentalism. 相似文献

Research into violence in schools has been growing steadily at an international level, and has shown high degrees of violence at various different levels. Given the seriousness of the problem, finding ways of responding to this issue in schools becomes an imperative for educationists. In this article, we engage with this problem by defending the view that whilst violence might be endemic in schools, there are also real possibilities for working towards different ways of being in relationship in schools. Firstly, we discuss Galtung’s understanding of violence and peace, paying particular attention to his concepts of structural and cultural violence, peacekeeping, peacemaking and peacebuilding. Secondly, we connect Galtung’s notions of peacemaking to Buber’s philosophy of dialogue, in order to make a case for an ‘epistemological shift’ which might enable individuals and communities to achieve ‘peace’. Finally, we direct our argument to the education context and put forward some concrete proposals for peacemaking in schools. 相似文献
