Comparison of power and EMG during 6-s all-out cycling between young and older women

Abstract To investigate the effects of ageing on the neural control strategies governing sprint cycling on a friction-loaded cycle-ergometer, 10 older (aged 70-83yr) and 8 young (aged 19-35yr) healthy women completed seven 6-s all-out cycling trials against varying loads. Root mean square (RMS), median frequency and muscle fibre conduction velocity were determined from the vastus lateralis of the dominant limb during each pedal stroke. Peak power was 43% lower in the older group compared to the younger (p??0.05). ΔRMS from the first to the sixth second during each trial was found to increase significantly with the development of power output in both groups (p?相似文献   

2019年度中国企业海外形象调查分析报告——以拉美五国为调查对象     

当代中国与世界研究院课题组  翟慧霞 《对外大传播》2020,(1):29-31

一、调查基本情况,新世纪以来,中拉关系得到了全面快速发展,逐步形成了全方位、宽领域、多层次的合作伙伴关系。当前中拉高层交往频繁,政治互信不断加深,整体合作取得历史性突破,中拉关系已经进入全方位发展的新时代。为了更好地了解中国企业在拉美地区的形象,2019年6月至8月,当代中国与世界研究院联合中国报道杂志社与凯度(Kantar China)共同在拉美五国开展了第6次中国企业海外形象调查。调查国家包括阿根廷、巴西、智利、墨西哥、秘鲁。  相似文献

突出知识创新促进生产发展--提铟新工艺产业化示范工程中的体会与认识     

长沙矿冶研究院 《中国科技论坛》1999,(3):63-63

广西大厂是我国重要的有色金属基地,矿产资源十分丰富,以锡为主,铟储量居世界第一,在开发矿山生产锡精矿的同时,产出高铟锌精矿,锌精矿含铟0.095%,杂质含量很高,共生关系极其复杂,不能用现有冶炼工艺处理,长期以来,这种精矿只能作配矿使用压价销售,一方面制约了企业经济效益的提高,另一方面使国家宝贵的铟资源严重流失.  相似文献

Treatment of specific developmental reading disorders, derived from single- and dual-route models     

Tressoldi PE  Lonciari I  Vio C 《Journal of learning disabilities》2000,33(3):278-285

A group of 21 participants with specific reading disorders was treated with a method derived from dual-route models and another group of 23 with a method derived from single-route models of reading. Both treatments were compared with four control treatments. The reading performance of each participant was compared with that of his or her chronological-age controls on the following variables: speed and accuracy of reading passage, isolated words and nonwords, and accuracy in homophone recognition. The treatment deriving from dual-route models produced significant improvements in the homophone recognition, compared to all other treatments. The treatment deriving from single-route models produced significant improvements, compared to all other treatments, in speed of word reading. Furthermore, these two treatments produced significant improvement with respect to all other treatments but one, in speed of nonword reading. These findings support the hypothesis that treatments derived from specific models of reading development are superior to other treatments. However the benefits obtained on the reading of isolated stimuli (words, homophones) did not significantly improve the reading of a passage. This fact suggests that treatments should include exercises involving passages or sentences.  相似文献
