Apurando os sentidos: sonoridades, performance e imagens nos rituais de Umbanda em Corumbá

O principal objetivo deste trabalho é investigar o ponto de vista nativo do conceito de sonoridades que constituem os rituais de Umbanda em Corumbá, município situado no Estado de Mato Grosso do Sul, Centro-Oeste brasileiro, pouco presente na literatura sobre o tema. Para a execução da pesquisa, foi utilizada a concepção de Seeger, na qual é preciso observar todo o contexto em que a manifestação musical ocorre, ou seja, o fato social musical total, com o intuito de compreender mais profundamente seus significados. Como metodologia, a pesquisa lançou mão da observação participante e entrevistas em profundidade com alguns dos importantes personagens inseridos no contexto umbandista local. O campo foi, igualmente, registrado por meio de fotografias, vídeos e gravações em áudio, a fim de viabilizar a criação de um acervo e, ainda, facilitar a transcrição e análise do material coletado e quiçá, viabilizar desdobramentos deste trabalho. Concluiu-se que a sua matéria-prima, as frequências sonoras, representam um instrumento ideal para a Umbanda, pelas seguintes razões: em primeiro lugar, as sonoridades, por sua natureza etérea, podem, assim como os orixás e as entidades espirituais, constituir vibrações invisíveis aos olhos dos leigos, mas não dos fiéis, que penetram os corpos e podem ser percebidos tanto no mundo espiritual quanto no mundo físico; em segundo lugar e, em decorrência do primeiro aspecto, é um perfeito meio para a comunicação tanto partindo do mundo espiritual em direção aos seus adeptos quanto vice-versa. É por meio das curimbas ou pontos que os orixás cantam as suas dijinas, ou seja, os seus nomes, realizando a continuidade de uma tradição ancestral. A pulsação promovida pelas vibrações sonoras traz consigo toda a simbologia cosmológica presente na Umbanda, revestida por um complexo e belo universo de narrativas, vestimentas, cores, cheiros, coreografias, afetos, intenções, realizações e afirmações identitárias dos componentes dos rituais vivenciados. Chegou-se, ainda, à conclusão de que podemos considerar o que os umbandistas da Tenda Nossa Senhora da Guia, principal grupo estudado, entendem por sonoridade, um fato social total, clássico conceito cunhado por Mauss. Estrategicamente e borrando as fronteiras entre resistência e comunhão com a comunidade maior em que está inserida na cidade, a Tenda aprofunda a cada dia as suas raízes, fincadas por Maria Theodora Gonçalves de Paula nos idos de 1920, ainda escrava. Apesar de ter findado oficialmente em 1888, a escravidão permaneceu nos rincões do País que resistia às mudanças sociais, econômicas e políticas que ocorriam em território nacional. A Tenda, hoje, é uma instituição que estabelece importantes trocas simbólicas, econômicas, políticas, sociais, culturais e espirituais, a partir de um território quilombola reconhecido pela Fundação Palmares e na esfera religiosa, pela a Federação dos Cultos Afro-Brasileiros e Ameríndios de Mato Grosso do Sul (FECAMS)

Effects of Small-Sided Games vs. Interval Training in Aerobic Fitness and Physical Enjoyment in Young Elite Soccer Players

The purpose of this study was to compare the effects of Small-Sided Games (SSG) vs. Interval Training (IT) in soccer training on aerobic fitness and physical enjoyment in youth elite soccer players during the last 8 weeks of the season. Seventeen U-16 male soccer players (age = 15.5 +/- 0.6 years, and 8.5 years of experience) of a Spanish First Division club academy were randomized to 2 different groups for 6 weeks: SSG group (n = 9) and IT group (n = 8). In addition to the usual technical and tactical sessions and competitive games, the SSG group performed 11 sessions with different SSGs, whereas the IT group performed the same number of sessions of IT. Players were tested before and after the 6-week training intervention with a continuous maximal multistage running field test and the counter movement jump test (CMJ). At the end of the study, players answered the physical activity enjoyment scale (PACES). During the study, heart rate (HR) and session perceived effort (sRPE) were assessed. SSGs were as effective as IT in maintaining the aerobic fitness in elite young soccer players during the last weeks of the season. Players in the SSG group declared a greater physical enjoyment than IT (P = 0.006; ES = 1.86 +/- 1.07). Coaches could use SSG training during the last weeks of the season as an option without fear of losing aerobic fitness while promoting high physical enjoyment.

Self-reported sitting time and physical activity: interactive associations with mental well-being and productivity in office employees

Background: Little is known about how sitting time, alone or in combination with markers of physical activity (PA), influences mental well-being and work productivity. Given the need to develop workplace PA interventions that target employees' health related efficiency outcomes; this study examined the associations between self-reported sitting time, PA, mental well-being and work productivity in office employees. Methods: Descriptive cross-sectional study. Spanish university office employees (n = 557) completed a survey measuring socio-demographics, total and domain specific (work and travel) self-reported sitting time, PA (International Physical Activity Questionnaire short version), mental well-being (Warwick-Edinburg Mental Well-Being Scale) and work productivity (Work Limitations Questionnaire). Multivariate linear regression analyses determined associations between the main variables adjusted for gender, age, body mass index and occupation. PA levels (low, moderate and high) were introduced into the model to examine interactive associations. Results: Higher volumes of PA were related to higher mental well-being, work productivity and spending less time sitting at work, throughout the working day and travelling during the week, including the weekends (p < 0.05). Greater levels of sitting during weekends was associated with lower mental well-being (p < 0.05). Similarly, more sitting while travelling at weekends was linked to lower work productivity (p < 0.05). In highly active employees, higher sitting times on work days and occupational sitting were associated with decreased mental well-being (p < 0.05). Higher sitting times while travelling on weekend days was also linked to lower work productivity in the highly active (p < 0.05). No significant associations were observed in low active employees. Conclusions: Employees' PA levels exerts different influences on the associations between sitting time, mental well-being and work productivity. The specific associations and the broad sweep of evidence in the current study suggest that workplace PA strategies to improve the mental well-being and productivity of all employees should focus on reducing sitting time alongside efforts to increase PA.

Number of Players and Relative Pitch Area per Player: Comparing Their Influence on Heart Rate and Physical Demands in Under-12 and Under-13 Football Players

The aim of the present study is to analyse the influence of different large-sided games (LSGs) on the physical and physiological variables in under-12s (U12) and -13s (U13) soccer players. The effects of the combination of different number of players per team, 7, 9, and 11 (P7, P9, and P11, respectively) with three relative pitch areas, 100, 200, and 300 m(2) (A100, A200, and A300, respectively), were analysed in this study. The variables analysed were: 1) global indicator such as total distance (TD); work:rest ratio (W:R); player-load (PL) and maximal speed (V-max); 2) heart rate (HR) mean and time spent in different intensity zones of HR (<75%, 75-84%, 84-90% and >90%), and; 3) five absolute (<8, 8-13, 13-16 and >16 Km h(-1)) and three relative speed categories (<40%, 40-60% and >60% V-max). The results support the theory that a change in format (player number and pitch dimensions) affects no similarly in the two players categories. Although it can seem that U13 players are more demanded in this kind of LSG, when the work load is assessed from a relative point of view, great pitch dimensions and/or high number of player per team are involved in the training task to the U12 players. The results of this study could alert to the coaches to avoid some types of LSGs for the U12 players such as:P11 played in A100, A200 or A300, P9 played in A200 or A300 and P7 played in A300 due to that U13>U12 in several physical and physiological variables (W:R, time spent in 84-90% HRmax, distance in 8-13 and 13-16 Km h(-1) and time spent in 40-60% V-max). These results may help youth soccer coaches to plan the progressive introduction of LSGs so that task demands are adapted to the physiological and physical development of participants.
