AbstractThe aim of this study was to test the correlation between knee-to-hip flexion ratio during a single leg landing task and hip and knee strength, and ankle range of motion. Twenty-four male participants from a professional soccer team performed a continuous single leg jump-landing test during 10s, while lower limb kinematics data were collected using a motion analysis system. After biomechanical testing, maximal isometric hip (abduction, extension, external rotation), knee extension and flexion strength were measured. Maximum ankle dorsiflexion range of motion was assessed statically using the weight bearing lunge test. Pearson correlation coefficients were calculated to determine the associations between the predictor variables (knee and hip strength, and ankle ROM) and the main outcome measure (knee-to-hip flexion ratio). Correlation between knee-to-hip flexion ratio and hip abductors strength was significant (r = ?0.47; p = 0.019). No other significant correlations were observed among the variables (p > 0.05). These results demonstrated that a lower hip abductors strength in male soccer players was correlated with a high knee-to-hip flexion ratio during landing from a single leg jump, potentially increasing knee overload by decreasing energy absorption at the hip. The results provide a novel proposal for the functioning of hip muscles to control knee overload. 相似文献

This article presents the concept and practice of adult education as a key issue for Brazil and other Latin American countries, both for formal and non-formal education in the public and private sectors. It includes citizen education focused on democratisation of society and sustainable development. The concept is pluralist and ideological as well as technical. All along the history of contemporary education it is essential to highlight the importance of the CONFINTEA conferences for the construction of an expanded vision of this concept. Adult education is understood as a human right. The right to education does not end when a person has reached the so-called ??proper?? age; it continues to be a right for the duration of everyone??s entire life. This article explores Paulo Freire??s contribution, particularly the methodology of MOVA (Youth and Adult Literacy Movement). It also presents the ecopedagogic perspective, which was inspired by Paulo Freire??s legacy. Finally, this article stresses the need to support a long-term policy for adult education, following the recommendations of the Civil Society International Forum (FISC) and CONFINTEA VI, both held in Belém, Brazil, in 2009. 相似文献

AbstractThis article introduces the core concepts that emerged from five environmental education action research studies conducted by a group called Learning Communities in Environmental Education, Science and Mathematics (CEAMECIM) from the Universidade Federal do Rio Grande (FURG) in the south of Brazil. The studies focus on teacher education processes in learning communities involving teachers, researchers and environmental educators, and the critical writing and reading texts of classroom recordings to problematise participants’ teaching practices. CEAMECIM used action research cycles to examine narratives of educational action, narratives from teachers concerning their development as environmental educators, and narratives of their development of a sense of belonging, with a particular focus on critiquing social models that are based on hierarchies and individuality. From this analysis, we propose a new perspective on being and learning how to become a learning community, crystallised by the belief that ‘we are more when we are together’. 相似文献

The purpose of the study was to examine the minimum number of monitoring days for reliably estimating physical activity (PA) and sedentary behaviour (SB) from accelerometer data in older adults. Forty-two older adults from a local senior centre participated in this study. Participants wore an ActiGraph wGT3X-BT on the right hip for 7 consecutive days. Accelerometer data were downloaded to a computer and converted to activity count data in 60s epochs. Time spent in SB and different PA intensity categories were estimated with commonly used activity count cut-points. Participants with at least 7 valid days of monitoring (≥10 h.day?1) were included in the analysis. Intraclass correlation coefficients (ICC) were calculated for determining single-day monitoring reliability. The Spearman-Brown prophecy formula was used to estimate the minimum number of monitoring days required for achieving an ICC of 0.80. Single-day ICC values for time spent in SB and PA intensity categories ranged from 0.45 to 0.61. Minimum number of monitoring days required for achieving an ICC of 0.80 ranged from 2.5 to 4.9 days. In this study, a minimum of 5 consecutive days of monitoring was required for reliably estimating SB and PA from accelerometer data in older adults. 相似文献
