郭沫若《女神》中标语口号诗句的再评价     

门红丽 《钦州学院学报》2008,23(2):82-84

郭沫若的<女神>中所表达出来的是一种情绪的恣意释放与飞升,这种恣意通常以一种呼喊的方式出现,即标语口号的诗句.这也成了后人诟病郭沫若诗歌的重要依据.但进入诗歌本身探讨"标语口号"诗句产生前因后果,为其存在的魅力找到合适的阐释也许更为重要,更可见出<女神>在新诗史上的意义.  相似文献

“终止”与“终止式”的辨析     

钮菲菲 《科教文汇》2012,(34):138-140

和声学中的半终止、全终止与曲式学中的半终止、全终止在所指上有所不同,但常被人们混同.本文比较了两者的不同,指出前者指的是终止式,即终止处相邻几个和弦的功能关系;而后者指的是终止所处的结构位置,期望在实际应用中能区分两者,不要将两者混为一谈.  相似文献   

场地自行车运动员踏蹬动作肌电研究   总被引：1，自引：0，他引：1  

袁鹏  刘伟民  吴翠娥  武桂新 《体育与科学》2008,29(6)

为从神经肌肉协调角度研究场地自行车运动员踏蹬动作技术特征,本文结合场地4km专项特点,研究10名场地自行车运动员在500w负荷下以100rpm、120rpm、130rpm、140rpm四种频率稳态骑行时下肢7块肌肉的EMG信号及四组单、双关节拮抗肌协调的变化规律。结果表明,更高踏蹬频率下RF活动显著提前至上提末段,TDC处平滑过渡另有机制。VL和GAS活动区域显著增大。TA突出表现为双峰模式,前峰在协调GAS传递能量和防止VM功能加强引起的膝关节过伸方面起重要作用。更高频率下RF与GM间拮抗机制表现为相反改变,BF/VL始终保持正相关,有助于下踏阶段膝-髋间的净能量传递。VL与GAS间显著负相关保证了近端环节至曲柄的高效传递,TA与GAS间显著负相关侧面证实TA双峰的重要意义。研究提示,专项频率(130-140rpm)下踏蹬动作有其特征的肌肉协调变化。  相似文献   

浅谈音乐教学中律动教学方法的运用     

黄志江 《辽宁高职学报》2009,11(11):69-70,94

主要阐述了律动教学方法在音乐课程中的运用。在众多的音乐教学改革原则、方法和模式中,律动教学具有一定的代表性,律动是一种技能,它是在有规律的动作中培养节奏感和韵律感。鉴于青少年学生活泼好动的年龄特点,在音乐课上,让他们通过体态律动去合上音乐节奏,不但可以使学生更快、更准地踏准音乐节奏,而且对音乐节奏的脉动,对音乐的情绪、情感内涵有更深刻的体验。  相似文献   

中国古典舞基本功训练与身韵训练关系之辨     

孟妍 《辽宁高职学报》2010,12(12):69-71

身韵是由身法和韵律组成的,也正是由于二者完美的结合,才真正体现出中国古典舞的风貌和精髓。在中国古典舞基本功的训练中,一定要让学生知道中国古典舞基本功训练与身韵训练两者是缺一不可的。如果基本功训练没有身韵就如同人没有了生命力,表现的只是空壳,这样就无法体现优美和精彩的中国古典舞。只有这两者相结合,才能表现出最完美的舞蹈之美。  相似文献

The effects of an increasing versus constant crank rate on peak physiological responses during incremental arm crank ergometry

Abstract

We examined the effects of concomitant increases in crank rate and power output on incremental arm crank ergometry. Ten healthy males undertook three incremental upper body exercise tests to volitional exhaustion. The first test determined peak minute power. The subsequent tests involved arm cranking at an initial workload of 40% peak minute power with further increases of 10% peak minute power every 2 min. One involved a constant crank rate of 70 rev · min^?1, the other an initial crank rate of 50 rev · min^?1 increasing by 10 rev · min^?1 every 2 min. Fingertip capillary blood samples were analysed for blood lactate at rest and exhaustion. Local (working muscles) and cardiorespiratory ratings of perceived exertion (RPE) were recorded at the end of each exercise stage. Heart rate and expired gas were monitored continuously. No differences were observed in peak physiological responses or peak minute power achieved during either protocol. Blood lactate concentration tended to be greater for the constant crank rate protocol (P = 0.06). Test duration was shorter for the increasing than for the constant crank rate protocol. The relationship between local RPE and heart rate differed between tests. The results of this study show that increasing cadence during incremental arm crank ergometry provides a valid assessment of peak responses over a shorter duration but alters the heart rate–local RPE relationship.  相似文献

This critical review reflects the current state of cadence research during cyclical activities at different intensities. Moreover, this review aims at making suggestions in the areas of evaluation, therapy and sporting performance in the light of all the different results reported in studies. A large number of researchers have tried to determine the ‘optimal’ cadence from imposed, preferred or spontaneously chosen cadences in order to improve efficiency and performances. Results are sometimes conflicting and difficult to explain or interpret. The authors have studied the variations in cadences using a reduced number of parameters, without links between energetic (oxygen consumption, ventilation), biomechanical (force, electromyography) and/or perceived parameters (rating of perceived exertion). Conclusions point out that the ‘optimal’ cadence cannot be unique and must be associated with the objectives and individual characteristics of the subject (skills and training level, anthropometric parameters). In the area of training and reconditioning, cadences would have to be set in relation to the nature of cyclical activities and the subjects’ condition.  相似文献
