The paper discusses 16 sportsmen finishing 400m running with maximum load on the pre-programmed automatic control runaway, makes sportsmen pile up lots of lactic acid, then determines respectively all different kinds of strength renewing sports' in clearing rate of Hla and observes relationship between Hla clearing away speed rate and renew sportsman's strength, and therefore find he optimum strength scope. The experiment shows that cleaing away Hla's fastest strength in 50%-65%, heart rate is between 145～165time/min.The research result proves that optimum renew sport's strength is 60% within 400 m, heart rate is 150-160 time/min. In this period the 16 sportsmen's running speed is (4.21±0.67) m/s, and it has no obvious differences in trainer's running speed oxygenless value (4.35±0.88)m/s (P0.05)
Vocal music is a special subject in music art, and vocal music teaching hasn't unified criteria and trainirng methods for a long time. We hold that we must correctly handle the dialectical relationship of voice and breath, relative stability and adjusting variation of laryns forward moving and backward moving of voice, voice and emation,which is also the general law to be followed in vocal music teaching.
Comparing with that of musical academies, musical specialty in normal universities has different characteristics in the quality of its pre-university students, the goal of cultivation, teaching environment, the size and design of curriculums. So, the vocal teaching system which fits the characteristics of normal music specialty must be built by teaching reforms, such as stressing its normal features, adopting pluralistic vocal teaching approaches, eliminating factious prejudices, strengthening artistic practice and so on.
当前,在大学体育课中如何开展素质教育,是高校体育教育界一个普遍关注的问题,本文从大学体育教学实践的角度,结合现代素质教育理论,对此作了认真的思考.作者认为,现阶段我国大学体育课堂教学隐含着与一般大学教育常识相悖的四个特点:①教程的非衔接性,它既给大学体育教学增加了难度,也给大学体育教学提供了广度.②成绩的非进展性,它使大学体育教育不能盲目追求技术与成绩的提高.③教育的非系统性,它使大学体育教学不能实施连续性与发展性的教学性质.④学生的非独立性,它使教学过程强调集体合作而不象其它课程那样强调独立操作.由于上述四个方面的特殊性,大学体育课在推行素质教育的过程中,既有易于接受素质教育理论的优势,也有难于实施素质教育的困惑.在大学体育课的发展走向上,作者通过逻辑推理,提出应创建"一个中心,三个基本点"的大学生体育课素质教育新观念."一个中心"是指大学体育教育要围绕学生的健康展开教学工作,要把体育教学面向全体学生和促进全面发展视为己任."三个基本点"是指大学体育教育是以提高身体素质、增强心理素质、养成社会参与为支撑点,开展课程教学与体育专业本领传授.说得更具体一点,提高身体素质要抓体能与技能的培养;增强心理素质要抓心理调适力与心理承受力的指导:养成社会参与力要抓社交艺术与集体观念的传播.认识到大学体育课"一个中心,三个基本点"的推行,必将受到大学体育特殊性的影响与制约,为此作者提出与新观念配套的三项改革,即改革教学内容,使大学生的体育学习从被动状态向主动状态转移;改革教学模式,使大学生体育学习由师从一人向师从多人转变;改革考核方式,使过程性评价向过程性评价与终结性评价发展.作者最后指出:"一个中心,三个基本点"的新观念一旦与体育教学内容、教学模式、考核方式改革相结合,一定能使大学体育课的作用与地位得到广大学生的认同与承认,从而真正使素质教育思想在大学体育中得到落实.
Compared with normal university education, PE teaching has four different characteristics: bad linking of teaching course, non-system of education, no developing in scores and dependence of learning. On the basis of the contradictory fact in carrying out quality education in PE class, the author suggests that PE in university should center on improvement the students' health, and be propped up by the improving mental and physical health and forming the ability of participating in society. Meanwhile, the teaching content, mode and test way should be reformed relevantly.
endurance athletes are separated randomly into control group and experimental group during the experiment lasting 3 months. Following indices are tested before and after experiment, Hb, speed at IAT, activities of RBC-SOD and RBC-GSH-Px, concentration of plasma MDA and RBC-MDA, Bla resumptive velocity after fixed load exercise and the best speed of 5000m. The results show that the indices and running speed of the experimental group are all better than that of the control group. It suggests that the medicine retard the occurrence of fatigue and speed up the resumption of performance and have positive effect on improving endurance performance.
