Indicators of sailing performance in youth dinghy sailing

Abstract

This study aimed to determine indicators of sailing performance in 2 (age) groups of youth sailors by investigating the anthropometric, physical and motor coordination differences and factors discriminating between elite and non-elite male optimist sailors and young dynamic hikers. Anthropometric measurements from 23 optimist sailors (mean ± SD age = 12.3 ± 1.4 years) and 24 dynamic youth hikers (i.e. Laser 4.7, Laser radial and Europe sailors <18 years who have to sail the boat in a very dynamic manner, due to a high sailor to yacht weight ratio) (mean ± SD age = 16.5 ± 1.6 years) were conducted. They performed a physical fitness test battery (EUROFIT), motor coordination test battery (Körperkoordinationstest für Kinder) and the Bucket test. Both groups of sailors were divided into two subgroups (i.e. elites and non-elites) based on sailing expertise. The significant differences, taking biological maturation into account and factors discriminating between elite and non-elite optimist sailors and dynamic hikers were explored by means of multivariate analysis of covariance and discriminant analysis, respectively. The main results indicated that 100.0% of elite optimist sailors and 88.9% of elite dynamic hikers could be correctly classified by means of two motor coordination tests (i.e. side step and side jump) and Bucket test, respectively. As such, strength- and speed-oriented motor coordination and isometric knee-extension strength endurance can be identified as indicators of sailing performance in young optimist and dynamic youth sailors, respectively. Therefore, we emphasise the importance of motor coordination skill training in optimist sailors (<15 years) and maximum strength training later on (>15 years) in order to increase their isometric knee-extension strength endurance.  相似文献

论图书馆权利体系中的自由与平等及其统一     

常安 《中国图书馆学报》2015,41(1):28-37

本文以自由与平等的冲突根源与内在联系为分析起点,认为作为制度正义的核心命题,二者间存在的内在张力和关联为图书馆权利体系的建构提供了参考。结合图书馆权利体系中自由与平等的具体内容,认为:图书馆作为一种正义的制度安排,在制度建构中必然会提出对自由和平等的主张和安排,这种制度正义性构成了图书馆权利体系中自由与平等统一的基石;图书馆需要通过积极的制度建构,以规范的形式确认自由和平等权利以及国家在实现图书馆自由平等权中的积极角色,使图书馆自由与平等权利从应有权利走向法定权利。  相似文献   

Electroosmotic flow hysteresis for dissimilar ionic solutions     

An Eng Lim  Chun Yee Lim  Yee Cheong Lam 《Biomicrofluidics》2015,9(2)

Electroosmotic flow (EOF) with two or more fluids is commonly encountered in various microfluidics applications. However, no investigation has hitherto been conducted to investigate the hysteretic or flow direction-dependent behavior during the displacement flow of solutions with dissimilar ionic species. In this investigation, electroosmotic displacement flow involving dissimilar ionic solutions was studied experimentally through a current monitoring method and numerically through finite element simulations. The flow hysteresis can be characterized by the turning and displacement times; turning time refers to the abrupt gradient change of current-time curve while displacement time is the time for one solution to completely displace the other solution. Both experimental and simulation results illustrate that the turning and displacement times for a particular solution pair can be directional-dependent, indicating that the flow conditions in the microchannel are not the same in the two different flow directions. The mechanics of EOF hysteresis was elucidated through the theoretical model which includes the ionic mobility of each species, a major governing parameter. Two distinct mechanics have been identified as the causes for the EOF hysteresis involving dissimilar ionic solutions: the widening/sharpening effect of interfacial region between the two solutions and the difference in ion concentration distributions (and thus average zeta potentials) in different flow directions. The outcome of this investigation contributes to the fundamental understanding of flow behavior in microfluidic systems involving solution pair with dissimilar ionic species.  相似文献   

How much exercise are older adults living in nursing homes doing in daily life? A cross-sectional study     

Philipe De Souto Barreto  Laurent Demougeot  Bruno Vellas  Yves Rolland 《Journal of sports sciences》2015,33(2):116-124

Information on the amount of exercise practised by nursing home (NH) residents is scarce. This study aimed at describing NH residents’ participation in exercise classes, as well as to examine whether the presence of a professional exercise instructor in the facilities is associated with residents’ exercise habits. The cross-sectional data of 5402 residents (median age = 88 years; mostly women (75.2%)) from 163 NHs in France were analysed. Adjusted logistic and linear regressions were performed to examine whether the presence of a professional exercise instructor in the NH was associated with exercise habits: exercise participation, frequency, duration, and levels. From the 5402 participants, 1914 were participating in exercise classes provided in the NH. Most of them had an exercise frequency of 1x/week or less. Median duration of exercise sessions was 45 min. Exercise levels were rated as: highly active (n = 487), intermediately active (n = 1096), and poorly active (n = 331). The presence of a professional exercise instructor working in the facility was significantly associated with exercise participation and with higher exercise frequencies and levels, and session duration. In conclusion, the presence of professional exercise instructors is associated with better exercise habits in NH residents. Improved exercise habits may potentially be translated into better health in this population.  相似文献
