Comparison of force-related performance indicators between heavyweight and lightweight rowers   总被引：1，自引：0，他引：1

The aim of this study was to examine biomechanical variables relating to the force production of men's Lightweight (LW) and Heavyweight (HW) rowing pairs. Seven HW and seven LW coxless pairs were studied under a range of stroke rates, from 20 spm to race rating (average of 33.7 spm for the HWs and 33.9 spm for the LWs). Each crew was equipped with biomechanical apparatus allowing the measurement of gate force, horizontal oar angle, and boat velocity. The HW crews exhibited significantly higher (p < 0.05) values for all variables examined, at all rates. Peak handle force was 26.2% to 30.2% higher in the HW group. Average handle force ranged from 18.7% to 22.1% higher than the LW group. Work per stroke was found to be 26% to 28% higher for the HW crews, and Power Per Kilogram was also greater for the HW crews, from 24.0% to 29.2%. The LWs were observed to be consistently, but not significantly, slower than the HWs (from 96.9% at the race situation, to 98.7% at 28 spm). These observations are important when considering biomechanical performance indicators in rowing, as significant changes in performance indicators may lead to only minimal alteration in boat velocity.  相似文献

Postcontraction influences on reaction time     

Etnyre B  Kinugasa T 《Research quarterly for exercise and sport》2002,73(3):271-281

The purpose of this study was to compare reaction time (RT) and fractionated RT components (premotor and motor times) between normal and postcontraction conditions. Twelve participants performed 20 trials each of control and postcontraction RT conditions. For the control condition, participants executed a learned, rapid, knee-extension contraction response to an auditory stimulus. The postcontraction condition was identical to the control condition except that the participants performed a 3-s isometric contraction of the knee extensor muscles prior to an auditory stimulus. Muscle activity was recorded from the quadriceps muscle group. Results indicated that the postcontraction condition was significantly faster than the control condition for the average RT, premotor time, and motor time. It was concluded that reaction time, processing time, and muscle contraction time for a learned task could be significantly reduced following an isometric contraction.  相似文献

Dualisms in Higher Education: a Critique of Their Influence and Effect          下载免费PDF全文

Bruce Macfarlane 《Higher Education Quarterly》2015,69(1):101-118

Dualisms pervade the language of higher education research providing an over‐simplified roadmap to the field. However, the lazy logic of their popular appeal supports the perpetuation of erroneous and often outdated assumptions about the nature of modern higher education. This paper explores nine commonly occurring dualisms: collegiality/managerialism, student‐centred/teacher‐centred, deep learning/surface learning, academics/non‐academics; research/teaching, old universities/new universities, liberal/vocational, public universities/private universities and higher education/further education. Illustrated by reference to a range of international contexts, it is argued that over‐reliance on dualisms among higher education scholars has adverse effects including narrowing the possibilities of research design and inhibiting intellectual advancement within the field.  相似文献

Leisure and Recreation in Australia:past,present and future     

Bruce Hayllar 《首都体育学院学报》2007,19(1):1-3

IntroductionLike most western countries,and probably those in the‘east’,contemporary leisure behaviour in Australia is shapedby its past.As the logical corollary,the leisure of today willlikely shape the future.As with the past,the future will bei mpacted upon by a range of social and economic changes?some predictable,some speculative,and some for which ourcurrent state of knowledge and forecasting cannot conceivablypredict.Reflecting on the PastAustralia’s leisure history has two distinct periods.Thefirst ...  相似文献
