chap 16 Stretching

chap 16 Stretching
• Holding a stretch for 8-15 sec. • Always done after a thorough warm-up • Must exhale and relax as eased into the hold position • Typically done after running, but before lifting – Cool Down – Allow the body time to rid itself of lactic acid – Be limber and Flexible for Resistance Training
CHAPTER
16
Stretching and Warm-Up
Chapter Outline
Warm-up Flexibility Factors affecting flexibility Frequency, duration, and intensity of stretching When should an athlete stretch? Proprioceptors and stretching Types of stretching
– Joint mobility – ballistic stretches – Flex runs/skipping – multidirectional activity – power moves
Ch. 4 (TLTP) Stretching and Flexibility
• Reduce tension in the hips and glutes
Proprioceptors and Stretching
• Stretch Reflex: During a rapid stretching movement the Ia fibers from the muscle spindle cause increased activation of the muscle that was stretched and its synergist. This causes the muscle to shorten. THIS SHOULD BE AVOIDED • Careful static stretching does not invoke the stretch reflex • Mechanoreceptor: GTO is sensitive to muscle tension. When stimulated it causes the muscle to relax.

简爱英文原版16章Chapter 16The day after the wedding, Jane wakes up as Mrs. Rochester. She feels a sense of duty and responsibility towards her new husband, Mr. Rochester. On their wedding night, Jane was filled with a mix of emotions - excitement, nervousness, and anticipation. She wasin awe of the fact that Mr. Rochester had chosen her, a poor and plain governess, to be his wife.As the days go by, Jane settles into her role as the mistress of Thornfield Hall. She describes her new life as a blend of happiness and humility. She takes pleasure in fulfilling her duties and managing the household, striving to meet Mr. Rochester's expectations. Jane also begins to explore the vast estate and familiarizes herself with its gardens, woods, and hidden corners.Despite her initial bliss, Jane senses a slight unease. She notices that Mr. Rochester becomes more distant and secretive as time goes on. He often leaves Thornfield Hall for long periods without any explanation, causing Jane to wonder about his whereabouts and activities. Jane's intuition tells her that something is not right, but she cannot put her finger on it.One evening, as Jane sits alone in her chamber, she is startled by a mysterious laughter echoing through the hallways. She investigates the source and discovers that it is coming from the third story of the house. Jane climbs the narrow staircase leading to the third floor and finds herself in a seemingly abandoned part of Thornfield. She feels an eerie presence and wonders who or what could becausing the laughter.Suddenly, Jane encounters a woman named Grace Poole, who is revealed to be the source of the laughter. Grace, a servant at Thornfield Hall, explains that she sometimes indulges in drinking too much and loses control over her actions. Jane is puzzled by this explanation and wonders why Grace is allowed to remain in such a position of responsibility despite her behavior.Jane becomes more curious about the mysterious happenings at Thornfield, especially after encountering the disturbed laughter and Grace's strange confession. She realizes that there is much more to Mr. Rochester's past than she knows. Jane's suspicion grows as she struggles to make sense of the secrets and hidden truths lurking within Thornfield Hall.In this chapter, the reader begins to get a glimpse of the unsettling events that are about to unfold. Jane's character is shown as someone who is determined and curious, willing to investigate and uncover the truth. Additionally, the introduction of Grace Poole and the eerie laughter suggest that there is more to Thornfield Hall than meets the eye. The reader is left with a sense of anticipation, wondering what lies ahead for Jane and Mr. Rochester.。

《医用生物化学自主学习》学习指导

《医用生物化学自主学习》学习指导

前言生物化学是研究生物体的化学组成和生命过程中化学规律的科学,从分子水平探讨生命现象的本质,研究生物体基本物质的化学组成、结构与功能,物质代谢与调节及其在生命活动中的作用,遗传信息传递的分子基础与调控规律。

其中核酸、蛋白质等生物大分子的结构与功能及基因结构、基因表达与调控等内容被视为分子生物学,分子生物学是生物化学的重要组成部分,也被视作生物化学的发展和延续。

简单地说,生物化学就是生命的化学,而医用生物化学主要研究人体的生物化学,是一门重要的医学基础课程。

生物化学的理论和技术已经渗透到医学科学的各个领域,掌握生物化学的基本理论、基本技能和基本实验方法,可以为进一步学习免疫学、微生物学、病理学、药理学、遗传学及细胞生物学等基础医学打下良好基础,现代医学的发展也经常运用生物化学的理论和技术来诊断、治疗和预防疾病,许多疾病的发病机制也需要从分子水平加以探讨。

《医用生物化学》课程的教学目的就是为医学生解释、解决医学实践中的有关问题提供理论依据、思路和方法,培养学生的独立观察问题、分析问题和解决问题的能力。

鉴于本学科理论性较强、比较抽象且进展较快的特点,我们的教学方法是在传统的课堂讲授的基础上,加入了自主学习(Self-Directed Learning)的内容,其目的就是希望通过讨论、辩论等形式,加深对相关理论知识的理解掌握和应用,而且通过学生自己包括资料查询、归纳总结以及整合报告的这种锻炼,培养其学习吸纳新知识的能力。

因为大学的课堂不仅仅是教会学生掌握若干个概念、公式或某个代谢过程,更应该教会学生在未来的学习和工作过程中,能够独立地分析解决问题,并随着学科的发展能够与时俱进、吐故纳新,后者应该更为重要,而且是能够终生受益的。

根据不同章节教学内容的特点,本学期我们为临床五年制专业安排了4次自主学习,临床七年制专业安排了5次自主学习,具体如下:临床五年制(理论总学时66学时,自主学习16学时)1)第四章第五节糖代谢紊乱2)第五章第五节胆固醇的代谢3)第九章物质代谢的相互联系和调节4)第十三章第三节真核基因的表达调控临床七年制(理论总学时75学时,自主学习19学时)1)Chapter 12 The Respiratory Chain & Oxidative Phosphorylation2)Chapter 19 Gluconeogenesis & Control of the Blood Glucose3)Chapter 27 Integration of Metabolism4)Chapter 31 Conversion of Amino Acids to Specialized Products5)Chapter 39 Regulation of Gene Expression尽管我们安排了自主学习的具体章节,但原则是立足于而不拘泥于这些章节涵盖的内容,一定程度上,我们会借助于每次自主学习的机会复习相关的背景知识,有着承上启下融会贯通的作用,因此我们为每个章节的自主学习设计了相关内容,包括引言、问题(围绕本章节需掌握、熟悉的内容提出,也是同学们需要讨论展示的主要内容)、参考文献和复习题。

The compound 2,3-BPG derived from the glycolytic pathway intermediate 1,3- BPG within erythrocytes. Synthesis of 2,3-BPG represents a reaction pathway for the consumption of glucose in RBC. Note that when glucose is oxidized by this pathway , the erythrocyte loses the ability to gain 2 moles of ATP from glycolytic oxidation of 1,3-BPG to 3-PG.
