Electromyographic analysis of thigh muscles during track cycling on a velodrome

We aimed to investigate neuromuscular activation of thigh muscles during track cycling at various speeds. Eight male competitive cyclists volunteered to participate in this study. Surface electromyography of the vastus lateralis, biceps femoris and adductor magnus muscles of the bilateral legs was recorded during track cycling on velodromes with a 250-m track. The participants were instructed to maintain three different lap times: 20, 18 and 16 s. The average rectified value (ARV) was calculated from the sampled surface electromyography. Significantly higher ARVs were observed in the right compared to left leg for the biceps femoris muscle during both straight and curved sections at 18- and 16-s lap times (P < 0.05). In the biceps femoris muscle, significant changes in ARVs during the recovery phase with an increase in speed were seen in the right leg only (P < 0.05). There were no significant differences in ARVs between the straight and curved sections for all three muscles (P > 0.05). From our findings, it was suggested that during track cycling on a velodrome the laterality of the biceps femoris muscle activity is a key strategy to regulate the speed, and fixed neuromuscular strategies are adopted between straight and curved sections for thigh muscles.  相似文献

Dependence of nucleotide physical properties on their placement in codons and determinative degree     

Berezhnoy AY  Duplij SA 《Journal of Zhejiang University. Science. B》2005,6(10):948-960

INTRODUCTION It is well-known from the genetic code structure that there exists a connection between codons and physical and chemical amino acid properties (Lewin, 1983). Codon properties in turn are defined by physical properties of the nucleotides from which they are compounded (Ratner, 1985; 2000). The most important properties of nucleotides as complex three-dimensional molecules are their dipole moment, heat of formation and energy of the most stable con- formation (Schneider and Be…  相似文献   

Prostate specific antigen in patients of benign prostate hypertrophy and carcinoma prostate     

T. Malati  G. Rajani Kumari  P. V. L. N. Murthy  Ch. Ram Reddy  B. Surya Prakash 《Indian journal of clinical biochemistry : IJCB》2006,21(1):34-40

Prostate Specific Antigen (PSA) has emerged as the most applicable and important tumor marker for carcinoma prostate. In the present study PSA was determined in serum of healthy subjects, patients of benign prostate hypertrophy (BPH) and Carcinoma Prostate (Ca−P) to evaluate its diagnostic efficiency in day to day management of prostate cancer patients and in differentiating patients of early prostate cancer from those with BPH. Receiver operating characteristic curve (ROC) revealed 2 ng/ml and 10 ng/ml cut off serum PSA level for BPH and untreated carcinoma prostate patients (Ca−P). An extremely significant increase (P<0.0001) was observed in mean PSA concentration in BPH patients and adenocarcinoma prostate patients when compared to healthy males. Clinical relevance of PSA was highlighted by a case study of cancer patient prior to any therapy till death.  相似文献

《登鹳雀楼》还是《登鹳鹊楼》？     

朱天运 《运城学院学报》2011,(4):27-30

唐诗现存各种版本中,王之涣《登鹳雀楼》又写作《登鹳鹊楼》,注释各异,莫衷一是。历史文献检索表明,用＂鹳雀楼＂者约占八成,而用＂鹳鹊楼＂者不到两成;唐宋元诗文皆用＂鹳雀楼＂写法;明清以后,始有＂鹳鹊楼＂之称。考该楼原为黄河岸边一座军事瞭望台,年久失修,鹳雀聚栖,因得其名。鹳雀是唐人对鹳的一般称呼,非鹳与喜鹊之集合。明中叶编撰的《大明一统志》是误植＂雀＂为＂鹊＂的肇始者,由此引起后人混乱。  相似文献   

环境规制、技术创新对全要素碳生产率的影响研究——基于中国省域的空间面板数据分析     

郭卫香  孙慧 《科技管理研究》2020,40(23):239-247

为探究环境规制政策是否能够实现碳减排和经济增长的“双红利”,本研究采用松弛模型的方向距离函数(SBM-DDF)模型和空间面板计量方法,通过测算2006-2016年中国省域全要素碳生产率,刻画中国省域全要素碳生产率的空间特征,进一步厘清环境规制、技术创新对全要素碳生产率的影响机理。研究结果显示：(1)中国各省份全要素碳生产率存在显著的空间集聚特征,其中高-高集聚(H-H)省份多位于东部沿海发达地区,而低-低集聚(L-L)省份多位中西部欠发达地区;(2)环境规制会促进全要素碳生产率的提升,且环境规制对全要素碳生产率的“本地效应”大于“邻地效应”;(3)技术创新在环境规制对全要素碳生产率的影响中存在部分中介效应。  相似文献   

跆拳道后旋踢技术动作的运动学特征分析          下载免费PDF全文

杨小芳 《河北体育学院学报》2016,30(3):81-85

采用三维高速摄像技术和运动生物力学原理,对后旋踢技术身体重心移动、动作所用时间、踝关节角度、膝关节角度和髋关节角度的运动学特征进行比较分析,得出结论:踢击腿在离地瞬间身体重心要快速向回旋方向移动;踢击腿膝关节最大程度弯曲,以缩短动作时间、加快踢击速度;踢击腿髋关节只有最大程度地弯曲,弯曲的膝关节才能快速展开;踢击腿的髋关节最大程度弯曲再打开时,踝关节能快速鞭打;支撑腿弯曲后在踢击腿踢出的瞬间,髋关节开始伸展,将对打击高度产生影响;踢击腿膝关节和髋关节最大程度弯曲时能增加击打力度.  相似文献
