  1. KNR 205: Scientific Principles of Coaching Introduction

  2. General course stuff • This is a new course...first for me, first for you, first for the school • It is designed for athletic coaching minors, but available to KNR majors • Have you had any of these... • 181 (A&P), 240 (Fitness), 280 (Ex. Phys.), 282 (biomechanics)? • If so, you’ll be duplicating information you’ve already covered. • This course was designed to cover aspects of all those courses, as well as 254 and 257, so that it would function as a general intro to kinesiology for minors

  3. General course stuff • Consequences for course organization • A lot of material • Broad and shallow approach • Focusing on “getting the idea” of a number of areas • Assessments that survey basic familiarity rather than mastery

  4. General course stuff • To do this week... • Go to the web site (www.cast.ilstu/smith) and download the syllabus. Read it. Submit the on-line quiz by Wednesday 24th at 9am. • On the 24th, bring a photo of yourself with your name printed legibly on the back, so that I can learn your names. No photocopies. You will get these back later in the semester. • Download the first slides and print them up. You should be able to print multiple slides per page – I recommend 3 slides a page • Read chapters 1 & 2 and answer the online quiz on chapter 2 by Friday 26th

  5. Chapter 1: Introduction • We’re going to skim this and get into the nitty gritty of chapter 2 ASAP • As this course is designed as the survey course for the coaching minor, it makes sense to read about the discipline a little first. • The best summary I can see in the text is on page 4, figure 1.1 • As you can see, it’s busy. There’s a lot of stuff, and a lot of influences

  6. Or, as we call it, kinesiology

  7. Part One: Anatomical Bases of Human Movement Functional Anatomy

  8. General intro... • Again, we’ll skim this introduction so we can get to the meat of chapter 2. • Functional anatomy is essentially about the structure and function of the human body • Can be from a number of levels of analysis • Subcellular • Tissues • Organs • The key point is that we are interested in the relationship between body structure and body function at whatever level of analysis we study

  9. Chapter 2 Basic Concepts of the Musculoskeletal System

  10. Objective (from syllabus) • To understand key concepts related to the structure and function of the skeletal, articular (joint) and muscular systems • You’ll find I stick very closely to the book throughout (like a drowning man clutching driftwood) • I see my role as a facilitator, whose job it is to simply relate and explain the content of the text to you • As such, I need you to simply point out where I’m not being clear

  11. Tools for Measurement • Bone density: • radiology • Bone structure: • chemical preparation • Movement: • goniometry (joint motion) • dynamometers (muscle force)

  12. The skeletal system • Functions • Mechanical • Physiological • Bone composition • Mechanical properties • Types of bone • Architecture of bone • Shape and organization • Architecture of long bones

  13. The articular system • Classification of joints • Features of synovial joints • Classification of synovial joints • Range of movements allowed by synovial joints • Joint protection, lubrication, and wear • The joint as the functional unit of the skeletal system
