2 0 0 0 m赛艇项目从基础理论分析 ,居于中等时间的有氧供能为主的运动项目 ,它不仅要求运动员具备较好的有氧工作能力和较好的肌肉克服阻力的能力 ,而具备有单位时间内肌肉克服阻力的能力。单位时间内肌肉克服阻力的能力越强 ,在其它条件不变的情况下 ,划桨力就越大 ,成绩就越好。所以提高赛艇运动员单位时间肌肉克服阻力的能力 ,是解决赛艇运动员划桨力提高的关键因素之一。1 测功仪训练对赛艇运动员划桨力的影响及其训练方法( 1 )测功仪训练对赛艇运动员划桨力的影响 :测功仪训练较荡桨训练、水上训练技术运用环节简单化 ,而且不受平衡… 相似文献

力量素质是指人体肌肉工作时，依靠肌肉紧张或收缩克服或对抗阻力的能力。他是人体运动的基本素质，也是衡量运动员身体训练水平的重要标志。人体的运动几乎都是和对抗阻力有关，有较大的肌肉力量，常常为取得优异运动成绩提供良好的基础。力量与其它素质有着极为密切的关系，也是掌握运动技能的基础。因此力量是一项基础素质，对运动员来说专项练习更需要进行一定的力量素质训练。 相似文献

A model of the motion of a single‐scull rowing hull has been developed and verified against rowing performance data. The model was then used to explore the effect of changes in the cyclic rowing force on the boat speed. The calculations have shown that the shape of the rowing force curve and the proportion of recovery time in the total stroke can have an important effect on the boat speed. It has also been shown that a study of the fluid mechanics of the oar blade would be advantageous in determining whether a reduction in the power wasted can be obtained by changing the ratio of rowing force to normal force. 相似文献

Assessment and feedback devices have been regularly used in technique training in high-performance sports. Biomechanical analysis is mainly visually based and so can exclude athletes with visual impairments. The aim of this study was to examine the effects of auditory feedback on mean boat speed during on-water training of visually impaired athletes. The German National Para-Rowing team (six athletes, mean ± s, age 34.8 ± 10.6 years, body mass 76.5 ± 13.5 kg, stature 179.3 ± 8.6 cm) participated in the study. Kinematics included boat acceleration and distance travelled, collected with Sofirow at two intensities of training. The boat acceleration-time traces were converted online into acoustic feedback and presented via speakers during rowing (sections with and without alternately). Repeated-measures within-participant factorial ANOVA showed greater boat speed with acoustic feedback than baseline (0.08 ± 0.01 m·s?1). The time structure of rowing cycles was improved (extended time of positive acceleration). Questioning of athletes showed acoustic feedback to be a supportive training aid as it provided important functional information about the boat motion independent of vision. It gave access for visually impaired athletes to biomechanical analysis via auditory information. The concept for adaptive athletes has been successfully integrated into the preparation for the Para-Rowing World Championships and Paralympics. 相似文献

目的:讨论一种在赛艇训练中增加训练阻力同时又不影响运动员技术动作的设备,即赛艇阻力器,在不同攻角、不同速度状态下,阻力、压力的变化,阻力与速度之间的关系以及增阻效果分析。方法:运用CFD软件FLUENT 6.2版本进行数值模拟。结果:速度不同,攻角相同状态下的阻力系数是相等的,阻力随速度和攻角的增大而增大,速度变化对阻力板阻力及压力的影响要大于角度的变化所产生的影响,阻力大小与速度的平方成正比,而阻力系数是常数。以155kg和175kg赛艇,阻力板攻角90°,赛艇划行速度5m/s为例,当无风状态时,安装阻力板的155kg赛艇增加的阻力(20.58N)比增加20kg重量(175kg)的阻力值(7.25N)大13.33N,增加的阻力值接近2倍。当顺风风速为3m/s时,阻力板增加的阻力为3.26N,比增加20kg重量的阻力值小3.99N,当逆风风速为3m/s时,阻力板增加的阻力为51.94N,比增加20kg重量增加的阻力值大44.69N,增加的阻力值近6倍多。结论:FLUENT软件对赛艇阻力板阻力计算是准确的,模拟的结果可以应用于具体的实际问题中。90°攻角状态下使用阻力板增加的阻力要优于由于赛艇艇重增加所达到的增阻效果。当处于顺风训练时,风速使阻力板增加的阻力值减小,减弱增阻效果,而逆风训练时,风速使阻力板产生的阻力值增大,加大了增阻效果。因此,采用阻力板训练,可以不改变赛艇的吃水和重心,保证运动员技术的完整性和连贯性,并且增加训练的强度,提高了训练的科学化水平。 相似文献

In a case study, Schaffert and Mattes reported the application of acoustic feedback (sonification) to optimise the time course of boat acceleration. The authors attributed an increased boat speed in the feedback condition to an optimised boat acceleration (mainly during the recovery phase). However, in rowing it is biomechanically impossible to increase the boat speed significantly by reducing the fluctuations in boat acceleration during the rowing cycle. To assess such a, potentially small, optimising effect experimentally, the confounding variables must be controlled very accurately (that is especially the propulsive forces must be kept constant between experimental conditions or the differences in propulsive forces between conditions must be much smaller than the effects on boat speed resulting from an optimised movement pattern). However, this was not controlled adequately by the authors. Instead, the presented boat acceleration data show that the increased boat speed under acoustic feedback was due to increased propulsive forces. 相似文献

Factors that affect boat speed are important determinants of rowing performance and should form the basis of feedback to rowers and their coaches. Biomechanical analysis of rowing has led to variables that are causally linked to boat speed. With modern technology, these variables can be measured and feedback can be presented instantaneously on-water, or be presented simultaneously with video after the event. This paper demonstrates the links between the criterion of success in rowing, the time for completing 2000 m and the forces acting on the boat, and describes an instrumentation system for providing feedback of these variables to rowers and coaches. These feedback techniques have been used with rowers from national to Olympic competition standard. Aspects of technique have been linked to the determinants of boat speed and several examples are presented here. The motor learning literature supports the effectiveness of kinetic information feedback for the improvement of motor skill and provides a relevant conceptual framework for the improvement of rowing performance. However, although rowers and their coaches value this feedback, further research must be undertaken to establish a sound basis for comparing the effectiveness of such feedback compared with traditional styles, such as verbal feedback of performance. 相似文献
