  1. ENS 304 Physiology of Exercise(section 2) Fred W. Kolkhorst, Ph.D. ENS 311; 594-1924 fred.kolkhorst@sdsu.edu office hours: MWF 9:00-11:00 http://www-rohan.sdsu.edu/course/ens304/public_html/section2/index.html

  2. Exercise Physiology • A biological study of physical activity stresses, both acute effects and training adaptations • Typical ergometers used to study exercise effects • cycle • treadmill

  3. Course Prerequisites • classified as a major in kinesiology or nutrition • grade of C (not C-) or better in BIOL 336 (Human Physiology) or equivalent course • ENS 210 or equivalent course • If WebPortal indicates that you have NOT met these prerequisites, you MUST provide documentation to me.

  4. How to be Successful in Physiology of Exercise • Class will begin at 8:00, everyone is to be on time. If you are late, enter the back door of the classroom so as not to disturb others • Cell phones are to be turned off during class • YOU determine your success through your consistent effort • Take an active part in your learning; don’t hesitate to ask questions or visit me, that’s what I’m here for • Attempt to understand rather than memorize • Study with classmates on a regular basis • Sit in the front, don’t miss class

  5. e-book available from McGraw Hill • Go to http://ebooks.primisonline.com • Click on the “McGraw-Hill e-book” icon (the big yellow ”e”). • Review the 5 steps listed on the screen then click “Next”. • On “Step 1” Click “Social Sciences and Humanities”. • Select the appropriate discipline, and then select text title.  (Be sure to select correct edition.) Powers & Howley, Exercise Physiology: Theory and Application to Fintess and Performance, 2007. • Follow the screen prompts.

  6. eInstruction Personal Response Pads(clickers) • We will use the CPS Personal Response Pads (i.e., “clickers”) • Purchase clicker from Aztec Shops • Before you can use clicker, mustregister through Blackboard • Instructions found in Blackboard (Tools/CPS Connection) • Must first create an account and register your clicker • Register clicker for class by Tue, Sep 4

  7. What is a Clicker? • Classroom Performance System • Each student has a clicker • Clickers send wireless signals • Computer has a receiver • Displays responses from class

  8. Why Clickers? • Questions will be posed during each class that require your response • Enhances student learning • Encourages interaction • Provides feedback • Increase active learning • Quizzes will be given periodically using the clickers • Exams will be administered with paper/pencil

  9. Course Grading • Four exams 40-60 points each (200 points) • Eight unannounced quizzes 5 points each • will throw out two lowest scores (60 points) • Plusses and minuses will be used for course grades

  10. Review of Physiological Principles • atoms, molecules, and ions • substrates products ATP  ADP + Pi + energy glucose  2 pyruvic acid  2 lactic acid

  11. Review of Physiological Principles Enzymes speed up reaction rates ATPase ATP <———> ADP + Pi + energy carbonic anhydrase H+ + HCO3- <——————> H2CO3 <——> H2O + CO2

  12. Review of Physiological Principles • pH • buffer • homeostasis • steady-state

  13. Absolute and Relative Comparisons A 100-lb woman can bench press 50 lb and a 200-lb man can bench press 75 lb. Who is the strongest? Explain. • 100-lb woman • 200-lb man • Absolute strength – man can lift 25 lb more than woman • Relative strength – woman can lift 0.5 lb / lb body weight whereas man can lift only 0.375 lb / lb body weight

  14. Absolute and Relative Comparisons Question Would you prescribe an absolute or relative target HR in a fitness class of 20- and 80-yr old clients? Explain.

  15. Interpreting GraphsRelationship between Variables • Independent variable – one that is manipulated/controlled by investigator • Dependent variable – one that is measured to determine response from varying independent variable

  16. Relationship of Variables Curvilinear Linear Blood [La] HR Running Velocity Running Velocity Identify the dependent and independent variables
