Exercise physiology
Exercise Physiology

  • A biological study of physical activity stresses, both acute effects and training adaptations

  • Typical ergometers used to study exercise effects

    • cycle

    • treadmill

Course prerequisites
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.

How to be successful in physiology of exercise
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

E book available from mcgraw hill
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.

Einstruction personal response pads clickers
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

What is a clicker
What is a Clicker?

  • Classroom Performance System

  • Each student has a clicker

  • Clickers send wireless signals

  • Computer has a receiver

  • Displays responses from class

Why clickers
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

Course grading
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

Review of physiological principles
Review of Physiological Principles

  • atoms, molecules, and ions

  • substrates products

    ATP  ADP + Pi + energy

    glucose  2 pyruvic acid  2 lactic acid

Review of physiological principles1
Review of Physiological Principles

Enzymes speed up reaction rates


ATP <———> ADP + Pi + energy

carbonic anhydrase

H+ + HCO3- <——————> H2CO3 <——> H2O + CO2

Review of physiological principles2
Review of Physiological Principles

  • pH

  • buffer

  • homeostasis

  • steady-state

Absolute and relative comparisons
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

Absolute and relative comparisons1
Absolute and Relative Comparisons


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

  • Independent variable – one that is manipulated/controlled by investigator

  • Dependent variable – one that is measured to determine response from varying independent variable
